I want to update the contents of a Google doc using the Google Drive API V3 (javascript):
https://developers.google.com/drive/v3/reference/files/update
I\'m
There are two issues:
You can work around issue #1 by writing your own upload functionality built on top of XHR. The following code should work on most modern web browsers:
function updateFileContent(fileId, contentBlob, callback) {
var xhr = new XMLHttpRequest();
xhr.responseType = 'json';
xhr.onreadystatechange = function() {
if (xhr.readyState != XMLHttpRequest.DONE) {
return;
}
callback(xhr.response);
};
xhr.open('PATCH', 'https://www.googleapis.com/upload/drive/v3/files/' + fileId + '?uploadType=media');
xhr.setRequestHeader('Authorization', 'Bearer ' + gapi.auth.getToken().access_token);
xhr.send(contentBlob);
}
To work around issue #2 you can send Drive a file type that Google Docs can import from, such .txt, .docx, etc. The following code uses the function above to update the content of a Google Doc using plain text:
function run() {
var docId = '...';
var content = 'Hello World';
var contentBlob = new Blob([content], {
'type': 'text/plain'
});
updateFileContent(fileId, contentBlob, function(response) {
console.log(response);
});
}
I build gDriveSync.js library to sync with google drive using javascript v3 api https://github.com/vitogit/gDriveSync.js
You can check the sourcecode of what I did (https://github.com/vitogit/gDriveSync.js/blob/master/lib/drive.service.js) , basically is a 2 step process, first you create the file and then you update it.
this.saveFile = function(file, done) {
function addContent(fileId) {
return gapi.client.request({
path: '/upload/drive/v3/files/' + fileId,
method: 'PATCH',
params: {
uploadType: 'media'
},
body: file.content
})
}
var metadata = {
mimeType: 'application/vnd.google-apps.document',
name: file.name,
fields: 'id'
}
if (file.parents) {
metadata.parents = file.parents;
}
if (file.id) { //just update
addContent(file.id).then(function(resp) {
console.log('File just updated', resp.result);
done(resp.result);
})
} else { //create and update
gapi.client.drive.files.create({
resource: metadata
}).then(function(resp) {
addContent(resp.result.id).then(function(resp) {
console.log('created and added content', resp.result);
done(resp.result);
})
});
}
}
Yo you can do this with fetch using the node-js google API, assuming you stored your token(s) already in a var named tokens
:
fetch("https://www.googleapis.com/upload/drive/v3/files/ID_OF_DRIVE_FILE?uploadType=media",
{
headers: {
'Content-Type':'multipart/related; boundary=a5cb0afb-f447-48a6-b26f-328b7ebd314c',
'Accept-Encoding': 'gzip',
'User-Agent': 'google-api-nodejs-client/0.7.2 (gzip)',
Authorization:tokens.token_type +" "+ tokens.access_token,
Accept:"application/json"
},
method:"PATCH",
body: "OK now iasdfsdgeaegwats AGAIN intresting",
cb(r) {
}
}).then(r => {
console.log(r);
});
