I am running into a problem with google drive rest api. I have a button and upon the user click, I get a blob excel file from my backend and upload the file to google drive. The file is being uploaded to the google drive, but when I opened it, it says '[object blob]'. The actual content isn't in the file. Here is my function for creating the file. I found this solution from here: Create File with Google Drive Api v3 (javascript)
var UploadExcelFile = function(name, data, callback){
const boundary = '-------314159265358979323846';
const delimiter = "\r\n--" + boundary + "\r\n";
const close_delim = "\r\n--" + boundary + "--";
const contentType = "application/vnd.google-apps.spreadsheet";
var metadata = {
'name': name,
'mimeType': contentType
};
var multipartRequestBody =
delimiter +
'Content-Type: application/json\r\n\r\n' +
JSON.stringify(metadata) +
delimiter +
'Content-Type: ' + contentType + '\r\n\r\n' +
data +
close_delim;
var request = gapi.client.request({
'path': '/upload/drive/v3/files',
'method': 'POST',
'params': {'uploadType': 'multipart'},
'headers': {
'Content-Type': 'multipart/related; boundary="' + boundary + '"'
},
'body': multipartRequestBody});
if (!callback) {
callback = function(file) {
console.log(file)
};
}
request.execute(callback);
}```
```This is the response from the server:
Response {type: "basic", url:
"http://localhost:54878/home/generateexcel", redirected: false,
status:
200, ok: true, …}
body: ReadableStream
locked: true
__proto__: ReadableStream
bodyUsed: true
headers: Headers
__proto__: Headers
ok: true
redirected: false
status: 200
statusText: "OK"
type: "basic"
url: "http://localhost:54878/home/generateexcel"}
I am passing in the name of the file and the blob excel file from the backend like so:
fetch('/home/generateexcel', {
method: 'POST',
body: JSON.stringify(postData),
headers: {
"Content-Type": "application/json"
},
}).then(function (response) {
response.blob().then(function (result)
UploadExcelFile('newfile', result)
});
}).catch(function (err) {
// Error :(
});
You want to upload the downloaded xlsx file to Google Drive.
You have already confirmed that the xlsx file could be downloaded.
When a xlsx file is uploaded, you want to convert to Google Spreadsheet.
You can use Drive API and the access token for uploading files.
If my understanding is correct, how about this modification? In this modification, I used FormData() for creating the request body and used fetch() for requesting to Drive API. I think that there are several solutions for your situation. So please think of this as just one of them.
Modified script:
I modified UploadExcelFile(). Please modify as follows and try again.
function UploadExcelFile(name, data) {
var metadata = {
name: name,
mimeType: "application/vnd.google-apps.spreadsheet",
};
var form = new FormData();
form.append('metadata', new Blob([JSON.stringify(metadata)], {type: 'application/json'}));
form.append('file', data);
fetch('https://www.googleapis.com/upload/drive/v3/files?uploadType=multipart&fields=id,name,kind', {
method: 'POST',
headers: new Headers({'Authorization': 'Bearer ' + gapi.auth.getToken().access_token}),
body: form
}).then((res) => {
return res.json();
}).then(function(val) {
console.log(val);
});
}
In my environment, I could confirm that this script worked. But if this didn't work in your environment, I apologize.

I'm trying to upload a photo on Google Photos, with google api, but i always get this error:
"status":{"code":3,"message":"Failed: There was an error while trying to create this media item."}}
I think that the problem is in the way i take the binary data of photo.
In this code i follow google photo api developers documentation, and it says, after take authorization, to:
1- Upload the raw bytes to a Google Server: to take upload-token
2- Use the upload token to create the media item.
This my node js code:
const photo = fs.readFileSync("fbimages/"+req.session.id_client+"/Prague/2020-05-30T17:29:14+0000_0.png", {
'encoding': 'binary',
'flag' : 'r'
});
var url= 'https://photoslibrary.googleapis.com/v1/uploads';
var headers= {
'Authorization': 'Bearer '+token,
'Content-type': 'application/octet-stream',
'X-Goog-Upload-Content-Type': 'image/png',
'X-Goog-Upload-Protocol': 'raw',
'X-Goog-Upload-File-Name': "2020-05-30T17:29:14+0000_0.png",
};
var body= photo
request({
url: url,
method:'POST',
headers: headers,
rejectUnauthorized: false,
body: JSON.stringify(body)
}, function(error, response, body1){
if(error)
{
console.log(error);
}
else
{
var upToken = body1.toString();
console.log(upToken);
var url= 'https://photoslibrary.googleapis.com/v1/mediaItems:batchCreate';
var headers= {
'Authorization' : 'Bearer '+token,
'Content-type': 'application/json',
};
var body= {
'newMediaItems': [
{
'description': 'Prague',
'simpleMediaItem': {
'fileName': 'prova',
'uploadToken': upToken,
}
}
]
};
request({
url: url,
method: 'POST',
headers: headers,
rejectUnauthorized: false,
body: JSON.stringify(body),
}, function(error, response, body){
if(error)
{
console.log(error);
}
else
{
res.send(JSON.parse(body));
}
});
}});
Please help me, if anyone has any idea!!
How about this modification?
Modification points:
I think that encoding: "binary" is not required.
In this case, ``const photo = fs.readFileSync("fig1.png", { flag: "r" });andconst photo = fs.readFileSync("fig1.png");` can be used.
Please modify body: JSON.stringify(body) to photo of const photo = fs.readFileSync("fig1.png", { flag: "r" });.
When above points are reflected to your script, it becomes as follows.
Modified script:
From:
const photo = fs.readFileSync("fbimages/"+req.session.id_client+"/Prague/2020-05-30T17:29:14+0000_0.png", {
'encoding': 'binary',

};
var body= { 'media-binary-data': photo }
request({

request(
{
url: url,
method: "POST",
headers: headers,
rejectUnauthorized: false,

},
function (error, response, body1) {
Note:
In this modification, it supposes that your token can be used for this API. Please be careful this.
When you want to directly put the uploaded image to an alubmn, please include albumId for requesting to https://photoslibrary.googleapis.com/v1/mediaItems:batchCreate.

Upload media
I'm trying to upload a file with the Google Drive api, and I have the metadata correct, and I want to ensure that the actual file contents make it there. I have a simple page setup that looks like this:
<div id="upload">
<h6>File Upload Operations</h6>
<input type="file" placeholder='file' name='fileToUpload'>
<button id='uploadFile'>Upload File</button>
</div>
and I have a the javascript setup where the user is prompted to sign in first, and then they can upload a file. Here's the code: (currently only uploads the file metadata....)
let uploadButton = document.getElementById('uploadFile');
uploadButton.onclick = uploadFile;
const uploadFile = () => {
let ftu = document.getElementsByName('fileToUpload')[0].files[0];
console.dir(ftu);
gapi.client.drive.files.create({
'content-type': 'application/json;charset=utf-8',
uploadType: 'multipart',
name: ftu.name,
mimeType: ftu.type,
fields: 'id, name, kind'
}).then(response => {
console.dir(response);
console.log(`File: ${ftu.name} with MimeType of: ${ftu.type}`);
//Need code to upload the file contents......
});
};
First, I'm more familiar with the back end, so getting the file in bits from the <input type='file'> tag is a bit nebulous for me. On the bright side, the metadata is there. How can I get the file contents up to the api?
So According to some resources I've found in my three day search to get this going, the file simply cannot be uploaded via the gapi client. It must be uploaded through a true REST HTTP call. So let's use fetch!
const uploadFile = () => {
//initialize file data from the dom
let ftu = document.getElementsByName('fileToUpload')[0].files[0];
let file = new Blob([ftu]);
//this is to ensure the file is in a format that can be understood by the API
gapi.client.drive.files.create({
'content-type': 'application/json',
uploadType: 'multipart',
name: ftu.name,
mimeType: ftu.type,
fields: 'id, name, kind, size'
}).then(apiResponse => {
fetch(`https://www.googleapis.com/upload/drive/v3/files/${response.result.id}`, {
method: 'PATCH',
headers: new Headers({
'Authorization': `Bearer ${gapi.client.getToken().access_token}`,
'Content-Type': ftu.type
}),
body: file
}).then(res => console.log(res));
}
The Authorization Header is assigned from calling the gapi.client.getToken().access_token function, and basically this takes the empty object from the response on the gapi call and calls the fetch api to upload the actual bits of the file!
In your situation, when you upload a file using gapi.client.drive.files.create(), the empty file which has the uploaded metadata is created. If my understanding is correct, how about this workaround? I have experienced the same situation with you. At that time, I used this workaround.
Modification points:
Retrieve access token using gapi.
File is uploaded using XMLHttpRequest.
Modified script:
Please modify the script in uploadFile().
let ftu = document.getElementsByName('fileToUpload')[0].files[0];
var metadata = {
'name': ftu.name,
'mimeType': ftu.type,
};
var accessToken = gapi.auth.getToken().access_token; // Here gapi is used for retrieving the access token.
var form = new FormData();
form.append('metadata', new Blob([JSON.stringify(metadata)], {type: 'application/json'}));
form.append('file', ftu);
var xhr = new XMLHttpRequest();
xhr.open('post', 'https://www.googleapis.com/upload/drive/v3/files?uploadType=multipart&fields=id,name,kind');
xhr.setRequestHeader('Authorization', 'Bearer ' + accessToken);
xhr.responseType = 'json';
xhr.onload = () => {
console.log(xhr.response);
};
xhr.send(form);
Note:
In this modified script, it supposes that Drive API is enabled at API console and the access token can be used for uploading file.
About fields, you are using id,name,kind. So this sample also uses them.
Reference:
gapi
If I misunderstand your question or this workaround was not useful for your situation, I'm sorry.
Edit:
When you want to use fetch, how about this sample script?
let ftu = document.getElementsByName('fileToUpload')[0].files[0];
var metadata = {
'name': ftu.name,
'mimeType': ftu.type,
};
var accessToken = gapi.auth.getToken().access_token; // Here gapi is used for retrieving the access token.
var form = new FormData();
form.append('metadata', new Blob([JSON.stringify(metadata)], {type: 'application/json'}));
form.append('file', ftu);
fetch('https://www.googleapis.com/upload/drive/v3/files?uploadType=multipart&fields=id,name,kind', {
method: 'POST',
headers: new Headers({'Authorization': 'Bearer ' + accessToken}),
body: form
}).then((res) => {
return res.json();
}).then(function(val) {
console.log(val);
});
With https://www.npmjs.com/package/#types/gapi.client.drive
const makeUploadUrl = (fileId: string, params: Record<string, boolean>) => {
const uploadUrl = new URL(
`https://www.googleapis.com/upload/drive/v3/files/${fileId}`
)
Object.entries({
...params,
uploadType: 'media',
}).map(([key, value]) => uploadUrl.searchParams.append(key, `${value}`))
return uploadUrl
}
const uploadDriveFile = async ({ file }: { file: File }) => {
const params = {
enforceSingleParent: true,
supportsAllDrives: true,
}
// create file handle
const { result } = await gapi.client.drive.files.create(params, {
// CAN'T have the upload type here!
name: file.name,
mimeType: file.type,
// any resource params you need...
driveId: process.env.DRIVE_ID,
parents: [process.env.FOLDER_ID],
})
// post the file data
await fetch(makeUploadUrl(result.id!, params), {
method: 'PATCH',
headers: new Headers({
Authorization: `Bearer ${gapi.client.getToken().access_token}`,
'Content-Type': file.type,
}),
body: file,
})
return result
})

I am trying to upload a file to a specific folder, but I am unable to do it.
Uploading is working correctly but it is not putting a file in a particular folder.
I am trying to do a Resumable upload with google drive rest version 3.
Assuming I already have a Folder ID.
First getting uploading URI :
uploadFileToDrive(name: string, content: string): Promise<Object> {
const url = `https://www.googleapis.com/upload/drive/v3/files?uploadType=resumable`;
const accessToken = localStorage.getItem('accessToken');
let headers = new Headers({
'Content-Type': 'application/json; charset=UTF-8',
'Authorization': 'Bearer ' + accessToken,
});
let options = new RequestOptions({ headers: headers }); // Create a request option
return this.http
.post(url, { name: name, role: 'reader', type: 'anyone', 'parents': [{"id":parentId}] }, options)
.toPromise()
.then(response => this.gDriveUploadFile(content, response.headers.get('location')));
}
Second uploading media :
gDriveUploadFile(file, url): Promise<any> { //file and url we got from first func
console.log(file + " "+ url );
const accessToken = localStorage.getItem('accessToken');
let headers = new Headers({
'Authorization': 'Bearer ' + accessToken,
'Content-Type': 'application/json; charset=UTF-8',
'X-Upload-Content-Type': file.type ,
});
let options = new RequestOptions({ headers: headers }); // Create a request option
return this.http.post(`${url}`, file, options) //call proper resumable upload endpoint and pass just file as body
.toPromise()
}
Also, I would like to know how I will be able to create a folder using google rest API in angular.
I'm trying to send a post request from my node server to an api that expects a file and other form data as an multipart/form-data.
Here is what my code looks like
var importResponse = function(csv){
stringify(csv, function(err, output){
request.post({
headers: {'X-API-TOKEN':token, 'content-type' : 'multipart/form-data'},
url: url,
formData: {
surveyId: surveyId,
file: {
value: output,
options: {
fileName: 'test.csv',
contentType:'text/csv'
}
}
}
}, function(error, response, body){
console.log(body);
});
});
}
Using request-debug here is the request:
request:
{ debugId: 1,
uri: 'https://co1.qualtrics.com/API/v3/responseimports',
method: 'POST',
headers:
{ 'X-API-TOKEN': 'removed',
'content-type':
'multipart/form-data; boundary=--------------------------010815605562947295265820',
host: 'co1.qualtrics.com',
'content-length': 575 } } }
and the response:
response:
{ debugId: 1,
headers:
{ 'content-type': 'application/json',
'content-length': '188',
'x-edgeconnect-midmile-rtt': '28',
'x-edgeconnect-origin-mex-latency': '56',
date: 'Wed, 18 Jul 2018 03:57:59 GMT',
connection: 'close',
'set-cookie': [Array],
'strict-transport-security': 'max-age=31536000; includeSubDomains; preload' },
statusCode: 400,
body:
'{"meta":{"httpStatus":"400 - Bad Request","error":{"errorMessage":"Missing Content-Type for file part. name=file","errorCode":"MFDP_3"},"requestId":"322a16db-97f4-49e5-bf10-2ecd7665972e"}}' } }
The error I'm getting is: Missing Content-Type for file part.
I've added this in the options:
options: {
fileName: 'test.csv',
contentType:'text/csv'
}
When I look at the request, it seems as though the form data isn't included. But perhaps that is just the request-debug not showing it.
I saw a similar SO question and the answer was to use JSON.stringify.
I tried changing my code to the following:
request.post({
headers: {'X-API-TOKEN':token, 'content-type' : 'multipart/form-data'},
url: url,
body: JSON.stringify({
surveyId: surveyId,
file: {
value: output,
options: {
fileName: 'test.csv',
contentType:'text/csv'
}
}
})
However, I got the following error:
{"meta":{"httpStatus":"400 - Bad Request","error":{"errorMessage":"Missing boundary header"}}}
What am I doing wrong?
UPDATE
When I tried changing the file value to a csv on my computer fs.createReadStream('test.csv'), it worked fine
file: {
value: fs.createReadStream('test.csv'),
options: {
contentType: 'text/csv'
}
}
So I assume there is something wrong with the way I'm giving the file. The output variable that I'm using as the file just looks like "QID1,QID2\nQID1,QID2\n1,2". I assume this is causing the problems, even though the error is a bit misleading. I tried creating a Readable that I found as a StackOverFlow answer like so:
var s = new Readable
s.push(output)
s.push(null)
However, this lead to a Unexpected end of input
{"meta":{"httpStatus":"400 - Bad Request","error":{"errorMessage":"Unexpected end of input"}}}
I found the issue. My first solution was fine, but instead of fileName it should have been filename
var importResponse = function(csv){
stringify(csv, function(err, output){
request.post({
headers: {'X-API-TOKEN':token, 'content-type' : 'multipart/form-data'},
url: url,
formData: {
surveyId: surveyId,
file: {
value: output,
options: {
filename: 'test.csv', //filename NOT fileName
contentType:'text/csv'
}
}
}
}, function(error, response, body){
console.log(body);
});
});
}
Is it possible that you are using the incorrect property name for your file?
A quick read of the forms info for the request Node module makes me think you should be using custom_file instead of file.
You can read more about it here: https://github.com/request/request#forms
Hey Eric check in which format they accept multipartRequest ,as I did for uploading the file on drive like this:
request(options, function (err, response) {
var boundary = '-------314159265358979323846';
var delimiter = "\r\n--" + boundary + "\r\n";
var close_delim = "\r\n--" + boundary + "--";
var fileContent = 'Sample upload :)';
var metadata = {
'name': 'myFile.txt',
'mimeType': 'text/plain\r\n\r\n'
};
var multipartRequestBody = delimiter + 'Content-Type: application/json\r\n\r\n' + JSON.stringify(metadata) + delimiter + 'Content-Type: ' + 'text/plain\r\n\r\n' + fileContent + close_delim;
request(options, function (err, response) {
var url = 'https://www.googleapis.com/upload/drive/v3/files?uploadType=multipart&access_token=' + JSON.parse(response.body).access_token;
var options = {
method: 'POST',
url: url,
headers: {
'Content-Type': 'multipart/related; boundary="' + boundary + '"'
},
body: multipartRequestBody
};
request(options, function (err, response) {
res.send({resultdata: response.body});
});
});
});
Set the multi-part as per your endpoint accepting.
Using frameworks like express(they automatically parse headers and response) and npm modules like multer for handling multipart form data helps cause they do all the heavy lifting for you
I am trying to integrate Google drive resumable file upload/update with my application. But when i update the file, file is updating in encoded format it is not taking the actual content. Encoded format is working for multiplepart uploadType but same content is not working for Resumable upload. Please find the below details
Step 1 : Start the resumable session
function uploadFile(fileData) {
var accessToken = 'ya29.nwI5Em6UnYGHvVzVx7lBk5tD-xzFl4_JG3_c-_t4FJ3owll_8i_rL5M17LFV6VlF7QE';
const boundary = '-------314159265358979323846';
const delimiter = "\r\n--" + boundary + "\r\n";
const close_delim = "\r\n--" + boundary + "--";
var contentType = fileData.type || 'application/octet-stream';
var metadata = {
'name': fileData.name,
'mimeType': contentType,
'Content-Type': contentType,
'Content-Length': fileData.size
};
var request = gapi.client.request({
'path' : 'upload/drive/v3/files',
'method' : 'POST',
'params' : {'uploadType':'resumable'},
'headers' : {
'X-Upload-Content-Type' : fileData.type,
'Content-Type': 'application/json; charset=UTF-8',
'Authorization': 'Bearer ' + accessToken,
},
'body' : metadata
});
request.execute(function(resp, raw_resp) {
var locationUrl = JSON.parse(raw_resp).gapiRequest.data.headers.location;
console.log(locationUrl);
uploadToLocationUrl(locationUrl, fileData);
});
}
Upto here it's fine I am getting Location Url and then calling a function to upload the file.
Step 2 : Resumable session initiation request
function uploadToLocationUrl(locationUrl, fileData)
{
var reader = new FileReader();
reader.readAsBinaryString(fileData);
reader.onload = function (e) {
var contentType = fileData.type || 'application/octet-stream';
var metadata = {
'name': fileData.name,
'mimeType': contentType,
'Content-Type': contentType,
'Content-Length': fileData.size
};
var base64Data = btoa(reader.result);
var multipartRequestBody =
delimiter +
'Content-Type: application/json\r\n\r\n' +
JSON.stringify(metadata) +
delimiter +
'Content-Type: ' + contentType + '\r\n' +
'Content-Transfer-Encoding: base64\r\n' +
'\r\n' +
base64Data +
close_delim;
var requestPost = gapi.client.request({
'path' : locationUrl,
'method' : 'PUT',
'headers' : {
'X-Upload-Content-Length' : fileData.size
},
'body' : multipartRequestBody
});
console.log(requestPost);
requestPost.execute(function(resp, raw_resp) {
console.log(resp);
});
}
}
Result : Updated file in google drive
---------314159265358979323846
Content-Type: application/json
{"name":"api.txt","mimeType":"text/plain"}
---------314159265358979323846

Sorry for the delayed answer,
you just need to change the uploadToLocationUrl function code
find below the updated code,
function uploadToLocationUrl(locationUrl, fileData,arrayBuffer)
{
var contentType = fileData.type || 'application/octet-stream';
var requestPost = gapi.client.request({
'path' : locationUrl,
'method' : 'PUT',
'headers' : {
'Content-Type': contentType,
"Content-Length": arrayBuffer.byteLength,
},
'data' : arrayBuffer
});
console.log(requestPost);
requestPost.execute(function(resp, raw_resp) {
console.log(resp);
});
}
you no need to send the metadata again, just byte array is fine.
