Forced 'Content-Type' header #156
Description
Gaxios rewrites the Content-Type header when the payload is of type 'object' in validateOpts:
if (opts.data) {
if (this.isReadableStream(opts.data)) {
opts.body = opts.data;
} else if (typeof opts.data === 'object') { // <-- Here
opts.body = JSON.stringify(opts.data);
opts.headers['Content-Type'] = 'application/json';
} else {
opts.body = opts.data;
}
}
I am currently updating to the google publisher v3 API (NodeJS) and I've hit a snag.
I am reading and passing the apk data as follows:
const apk = fs.readFileSync(apkFilePath);
this.publisher.edits.apks.upload({
editId,
packageName,
media: {
mimeType: 'application/vnd.android.package-archive',
body: apk
}
}, (err, res) => {});
In this case, I am explicitly specifying the mimeType to the one required by the upload API, apk variable is of type Buffer, but a typeof check returns 'object'. The upload API then returns
Media type 'application/json' is not supported. Valid media types: [application/octet-stream, application/vnd.android.package-archive]
I'm not sure why there's a need to force the header and serialization when the user has explicitly set them, maybe I am missing something though 🤔
