responseType on Google Drive API v3 Files: get

[brunoimbrizi]

Originally submitted to IssueTracker https://issuetracker.google.com/issues/174302344 and recommended to file this in here "Since your feature request seems to be related to gapi.client library"

A short description of the request:
Define responseType on Google Drive API v3 Files: get, which relevant with alt=media.

What is the purpose of this new feature?
To be able to get the response body as blob or arraybuffer. At the moment it seems only possible to get the body as plain text.

Scenario
I am using the Google Drive API to create an application in the browser. I need to download the content of a file stored on Drive.

The v3 documentation for gapi.client.drive.files.get mentions alt=media which works and returns a response body. The issue is that body is plain text and it is not clear it if is possible to define a different responseType i.e. blob or arraybuffer.

The v2 documentation sheds some light on the topic with a JavaScript example to download a file's content. Using a custom XMLHttpRequest it is possible to define a responseType.

Shouldn't it be possible to do the same with gapi.client.drive.files.get?

Hey dude, I am succeded to do it in this way:

const res = await drive.files.get({
  fileId: ctx.params.fileId,
  alt: 'media',
}, {
  responseType: 'arraybuffer',
});

Hey,

I get a 502 from the server when I try it. I can see that my browser is POSTing to the API with the request body {"responseType":"arraybuffer"} when I do this:

var data = gapi.client.drive.files.get({
    'fileId': fileId,
    'alt': 'media'
}, {
    'responseType': 'arraybuffer',
});

Thanks for the feature request. Unfortunately the GAPI client does not support binary blobs well and the Drive documentation is the appropriate way to perform this task.

Managed to read the body response in this manner (Angular) -

getFileFromPicker(fileId: string, mimeType: string){
return gapi.client.drive.files.get({
"fileId": fileId,
"mimeType": mimeType,
"alt": "media",
})
}

this.getPickedFile(fileId, mimeType).then(async (value: any) => {
const blob = await this.base64toBlob(data:${mimeType};base64,${btoa(value.body)});
let file = new File([blob], fileName); //File of the pdf document
});

async base64toBlob(base64string: string) {
const base64 = await fetch(base64string);
return await base64.blob();
}
