cant make signed url

[stellanhaglund]

I get this

/home/server/node_modules/gcloud/node_modules/google-auto-auth/index.js:47
client.authorize(function (err) {
^
TypeError: undefined is not a function
at /home/server/node_modules/gcloud/node_modules/google-auto-auth/index.js:47:12

ibrary/lib/auth/googleauth.js:124:9

when running this

app.get('/file/:fileId', function(req, res){

var remoteFile = bucket.file(req.params.fileId);

remoteFile.getSignedUrl({
    action: 'read',
    expires: '2025'
}, function(err, url) {
    if (err) {
        console.log('err');
        return;
    }

    console.log(url)

});

});

Can you show where you gave auth configuration to gcloud?

[stellanhaglund]

var projectId = 'idid'; // E.g. 'grape-spaceship-123'

var gcloud = require('gcloud')({
projectId: projectId
});

Thanks, I was able to reproduce. Will keep you posted!

I published a new version of google-auto-auth that will return a more helpful error. The problem here is in order to sign URLs, we need two properties that can't be detected in an auto-auth'd environment (like on GCE): client_email and private_key.

To enable this method to work, you'll have to authenticate with a keyfile (JSON, pem, or p12).

I'm able to download a file with the .download() method, but using getSignedURL() results in the error

TypeError: bucket.file(...).getSignedURL is not a function

I'm using a firebase-storage bucket, I have a json key file including client_email and private_key.
Is this still a ACL / rights issue ?

Heres the relevant part of the stackstrace:

tryCatch (.../node_modules/regenerator-runtime/runtime.js:62:40)
    GeneratorFunctionPrototype.invoke [as _invoke] (.../node_modules/regenerator-runtime/runtime.js:336:22)
    GeneratorFunctionPrototype.prototype.(anonymous function) [as next] (.../node_modules/regenerator-runtime/runtime.js:95:21)

Try calling getSignedUrl (note the casing). It probably should have been getSignedURL, shouldn't it have?

[andreasgrimm]

That works!

and it's what the offical API docs say as well: https://googlecloudplatform.github.io/gcloud-node/#/docs/v0.36.0/storage/file?method=getSignedUrl

Thanks a ton !!
