I have a jquery code where I send files with xhr post, this code works fine for other files but for files with ".obj" extension it doesn't send any value in post (it doesn't send test data independent of the file either)
When I print the file value to the console, I can see that it is written correctly
Code;
var form = new FormData();
form.append("file", file);
form.append("test", "test");
var xhr = new XMLHttpRequest();
xhr.open("POST", "desk.php", true);
xhr.onload = function ()
{
if (xhr.status == 200)
{
var response = JSON.parse(xhr.responseText);
console.log(response);
}
};
xhr.send(form);

I have a XMLHttpRequest to send a courseName to php file on the server like this:
const xhr = new XMLHttpRequest();
xhr.onload = function(e) {
if(this.readyState === 4) {
console.log("Server returned: ",e.target.responseText);
}
};
const fd = new FormData();
fd.append("courseName", 'Math');
xhr.open("POST", "upload.php", true);
xhr.send(fd);
PHP:
<?php
echo $_FILES['courseName']
?>
But nothing is returned, I'm confused please help... it should return Math, Doesn't it?
The network doesn't show any data sent over.
How to use FormData for AJAX file upload?
Shows you how to send files using FormData ...

I've read the readme file at https://github.com/cloudinary/cloudinary_tinymce but still can't understand how to do it. Plus they do it on Ruby on Rails, which doesn't really help.
Do I really need to do server-side endpoint? It only asks for a signed URL. But I don't need it to be signed. How do I do it within JavaScript and HTML alone? I don't want to do anything inside my server except to render templates.
edit: I tried it with image_upload handler and it uploads to my Cloudinary account. But it won't give me the url for the image on successful upload (I expect to get something like https://res.cloudinary.com/strova/image/upload/v1527068409/asl_gjpmhn.jpg). Here's my code:
images_upload_handler: function (blobInfo, success, failure) {
var xhr, formData;
xhr = new XMLHttpRequest();
xhr.withCredentials = false;
xhr.open('POST', 'https://api.cloudinary.com/v1_1/strova/upload');
xhr.onload = function () {
var json;
if (xhr.status !== 200) {
failure('HTTP Error: ' + xhr.status);
return;
}
json = JSON.parse(xhr.responseText);
success(json.location);
};
formData = new FormData();
formData.append('file', blobInfo.blob(), blobInfo.filename());
formData.append('upload_preset', cloudinary_upload_preset);
xhr.send(formData);
}
Try "faking" a POST request for one. I am still trying. To figure out why the documentation "requires" a POST request. The PHP example: https://www.tinymce.com/docs-3x//TinyMCE3x#Installation/ just echos back what gets POSTED to server. The plugin must be interpolated the posted content.
Inspired by your code, I was able to resolve this pain point for myself. The missing part was that after parsing the response, the secure_url from the response needed to be called and assigned to json in the format required by TinyMCE. Following is the code:
images_upload_handler: function (blobInfo, success, failure) {
var xhr, formData;
xhr = new XMLHttpRequest();
xhr.withCredentials = false;
//restricted it to image only using resource_type = image in url, you can set it to auto for all types
xhr.open('POST', 'https://api.cloudinary.com/v1_1/<yourcloudname>/image/upload');
xhr.onload = function () {
if (xhr.readyState == 4 && xhr.status == 200) {
var response = JSON.parse(xhr.responseText);
var url = response.secure_url; //get the url
var json = {location: url}; //set it in the format tinyMCE wants it
success(json.location);
}
};
formData = new FormData();
formData.append('file', blobInfo.blob(), blobInfo.filename());
formData.append('upload_preset', '<YourUnsignedUploadPreset>');
xhr.send(formData);
}
I am trying to upload a image to server,In that i have converted image to base64encode string and i need to pass that base64encode string to webservice,that webservice convert the base64 string to file and saving in database.but base64encode string has huge length approximately(85,000) when i pass this string to webservice i am getting the following error.
Failed to load resource: the server responded with a status of 400 (Bad Request)
i need to pass this by using only XMLHttpRequest() with out using the ajax,jquery please help me.
below is my code.
var filesToBeUploaded = document.getElementById("afile");
var file = filesToBeUploaded.files[0];
var reader = new FileReader();
reader.onload = function(event) {
var binaryStringResult = reader.result;
var binaryString =binaryStringResult.split(',')[1];
var xhr = new XMLHttpRequest();
xhr.open("POST","http://url/api/jsonws/Global-portlet.org_roles/add-file-entry?repositoryId=11304&folderId=0&sourceFileName=test108.jpeg&mimeType=image%2Fjpeg&title=test108.jpeg&description=test108.jpeg&changeLog=test108.jpeg&basecode64="+ binaryString);
xhr.setRequestHeader("Authorization","BasicbmFyYXlhbmFAdmlkeWF5dWcuY29tOnRlc3Q=");
xhr.setRequestHeader('Content-type','application/x-www-form-urlencoded');
xhr.send();
xhr.onload = function() {
alert('in sucess');
};
xhr.onerror = function(e) {
alert('in error');
};
}
reader.readAsDataURL(file);
For POST, don't include it in the URL, you need to put it in the body, i.e.
xhr.send(binaryString);
I doubt your Content-Type of application/x-www-form-urlencoded is correct in this case.
I think the issue that you encountering here is that you are exceeding the maximum length of a query string.
What you need to do is something like the following:
var xhr = new XMLHttpRequest();
var url = "http://url/api/jsonws/Global-portlet.org_roles/add-file-entry";
var params = "repositoryId=11304&folderId=0&sourceFileName=test108.jpeg&mimeType=image%2Fjpeg&title=test108.jpeg&description=test108.jpeg&changeLog=test108.jpeg&basecode64="+ binaryString;
xhr.open("POST", url, true);
xhr.setRequestHeader("Content-type", "application/x-www-form-urlencoded");
xhr.setRequestHeader("Content-length", params.length);
xhr.setRequestHeader("Connection", "close");
xhr.onreadystatechange = function() {
if(xhr.readyState == 4 && xhr.status == 200) {
alert(xhr.responseText);
}
}
xhr.send(params);
Hope that helps
I have a text file on my server and I want to upload a text in it using XMLHttpRequest. It is downloaded successfully via GET method, but when I try to POST it I get 404 error.
var r1 = new XMLHttpRequest();
r1.open("GET", "db.txt", false);
r1.send();
var str = r1.responseText + "foo text";
var r2 = new XMLHttpRequest();
r2.open("POST", "db.txt", false);
r2.send(str);
Doing a direct upload as you're trying would be a security concern in most places and is generally not permitted... What you need to do is have a middle layer on your server to handle the request and write the file to disk safely.
You can easily upload a file using something like this:
var jsonBlob = new Blob([someJSON], {type: "text/plain;charset=utf-8"});
var data = new FormData();
data.append("filename", "new.json");
data.append("json", jsonBlob);
var xhr = new XMLHttpRequest();
var postURL = "http://example.com/post_target";
xhr.open("POST", postURL, true);
xhr.onload = function(e) {
if (this.status == 200) {
console.log(e.target.response);
}
};
xhr.send(data);
Where postURL is an endpoint which can handle file uploads.
If you post what language(s) you have available on your server (PHP?) I can give some example code to handle the upload on the server's end.
Give a HTTP Filesystem API which accepts
GET /storage/filename
PUT /storage/filename
Request body: the file contents
and these headers
Content-Length: ...
Content-Type: application/octet-stream
How can one build a backbone.js File Model which works with it? (e.g. get file contents in a variable, put back updated contents)
If backbone.js doesn't support this, how would jQuery ajax requests look like?
While I haven't found support in jQuery/backbone, here's how it can be done:
var xhr = new XMLHttpRequest();
xhr.open('GET', "url", true);
xhr.setRequestHeader("Authorization", token);
xhr.responseType = "text";
xhr.onload = function(e) {
if (this.status == 200) {
var contents = this.response;
console.log("RECEIVED " + contents);
}
};
xhr.send();
