file upload using axios in react

I am uploading file in react using axios.
when I am doing
alert(values.attachedFile[0]);
but when I am sending values.attachedFile[0] in axios post request enpty thing is going.
const { result } = await axios.post(app.resourceServerUrl + '/file/upload', {
data: values.attachedFile[0],
headers: {
'Content-Type': 'multipart/form-data',
},
});
but as part of request is is going empty.
what mistake I am doing?

To upload file with axios you need to use FormData:
const formData = new FormData();
// ...
formData.append("data", values.attachedFile[0]);
axios.post(app.resourceServerUrl + '/file/upload', formData, {
headers: {
'Content-Type': 'multipart/form-data'
}
})

Sending formData to API in reactjs

I am using html2canvas to convert HTML to images.
So whenever the user submits the form, I am trying to send the image as blob and other details to the API using formData.
I am sending formData to the API to process the submitted data.
When user click on submit button, below code is responsible.
function handleReport(target = 'body') {
html2canvas(document.querySelector(target))
.then((canvas) => {
let pngUrl = canvas.toDataURL(); // PNG is the default
fetch(pngUrl)
.then((res) => res.blob())
.then((blob) => {
const formData = new FormData();
formData.append('images', [blob]);
// textarea content
formData.append('description', textAreaValue);
// user device info
formData.append('device[platform]', device.payload.platform);
formData.append('device[name]', device.payload.name);
formData.append('device[version]', device.payload.version);
formData.append('device[ip]', device.payload.ip);
formData.append('device[id]', device.payload.id);
formData.append('device[app_version]', device.payload.app_version);
formData.append('device[device_token]', device.payload.device_token);
dispatch(actions.contactUs(util.getApiToken(), util.getToken(), formData));
});
})
.catch((error) => {
console.log(error);
});
}
action definition :
export function contactUs(apitoken, token, payload) {
return {
[RSAA]: {
endpoint: `${API_ENDPOINT}/contact-us?api_token=${apitoken}`,
headers: {
...AUTH_HEADERS,
Authorization: `Bearer ${token}`,
},
method: 'POST',
body: payload,
// body: JSON.stringify(payload),
types: [
types.CONTACT_US_REQUEST,
types.CONTACT_US_RECEIVE,
],
},
};
}
Given below is the screenshot (not full screenshot) of payload (what user sent after clicking submit button) in Chrome browser
and this is the response I am getting from API
What is my problem !
I am sending all required keys (refer formData) but don't why am I getting error like :
description field is required

My header content is -
AUTH_HEADERS = {
'X-Authorization': X_AUTHORIZATION,
'Content-Type': 'application/json',
};
I just resolved my issue by removing 'Content-Type': 'application/json' which I was sending.
Now I am sending request to API without header.
headers: {
'X-Authorization': X_AUTHORIZATION,
Authorization: `Bearer ${token}`,
},
Now everything is working is fine.

react js fetch api using file upload not being sent to body

Here is my code
let formData = new FormData();
// Update the formData object
formData.append(
"myFile",
this.state.product_picture,
this.state.product_picture.name
);
var options = { content: formData };
const token = JSON.parse(localStorage.getItem('token'));
const requestOptions = {
method: 'POST',
headers: {
'Accept': 'application/json',
'Content-Type': 'application/json',
},
body: JSON.stringify({
product_name:this.state.product_name,
product_description:this.state.product_description,
product_picture:formData,
category_name:this.state.category_choosen,
})
};
fetch('http://cms.test/api/products/insert_supplier_product?token='+token, requestOptions)
.then(response => response.json())
.then(data => {
this.setState({ product: data.product})
})
.catch(error =>{
console.log("Product creation error", error);
});
I have this fetch api its always giving a 422 response I think what is happening is that its not reading a file as I want to upload a file it all works in postman but when using react it crashes
The body here is the problem
inside the state there are some strings but inside the this.state.product_picture there is a file
Hope someone can help! Thank you!
SOLUTION: Using axios to call the api solved my problem

You cannot send a file in a JSON object in a request( atleast not without Base64 encoding it). Change your code in the following way to send a file with your form.
let formData = new FormData();
// Update the formData object
formData.append(
"myFile",
this.state.product_picture,
this.state.product_picture.name
);
formData.append("product_name",this.state.product_name);
formData.append("product_description",this.state.product_description);
formData.append("category_name",this.state.category_choosen);
var options = { content: formData };
const token = JSON.parse(localStorage.getItem('token'));
const requestOptions = {
method: 'POST',
headers: {
'Accept': 'application/json',
'Content-Type': 'multipart/form-data',
},
body: formData
};
fetch('http://cms.test/api/products/insert_supplier_product?token='+token, requestOptions)
.then(response => response.json())
.then(data => {
this.setState({ product: data.product})
})
.catch(error =>{
console.log("Product creation error", error);
});

How to download ZIP file from reactjs using post api?

How to download zip file from reactjs using POST API.
The request is coming from nodejs in binary form

you can use jszip link https://github.com/Stuk/jszip like
import zipTargetFiles from '/path'
zipTargetFiles( data ).then(file => {
//operations
})
if you use fetch like this.
fetch('URL', {
method: 'POST',
headers: {
'Accept': 'application/json',
'Content-Type': 'application/json',
},
body: JSON.stringify({
//Body
})
}).then((response)=>{
//here is youu want zip data
var zip = new JSZip();
var zipData = response.data //
// Add an top-level, arbitrary text file with contents
zip.file("response.txt", zipData);
// Generate the zip file asynchronously
zip.generateAsync({type:"blob"})
.then(function(content) {
// Force down of the Zip file
saveAs(content, "zipFile.zip");
});
}).catch((error)=>{
console.log(error)
})

You can use JsZip on Client Side. Then, do a request with axios. Like this:
request = (currentUrl: string): Promise<void> => axios({
url: currentUrl,
method: 'GET',
responseType: 'blob',
}).then((response) => {
const url: string = window.URL.createObjectURL(new Blob([response.data]));
});

Google Drive API and file uploads from the browser

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
})
}
