iOS Upload file to Google Cloud Storage - getting 401: 'Login Required'

问题

I am having trouble figuring out how to upload a file to a Public Access bucket to Cloud Storage.

I have set up a bucket and set it's ACLs to READ and WRITE for all users.
I have enabled the Cloud Storage JSON API and the Cloud Storage API.
I have created an API key for browser applications that allows any referrer.

Here is my code in Swift:

private lazy var googleServiceStorage:GTLServiceStorage = {
   var storage = GTLServiceStorage()
   storage.APIKey = "AIzaSy**********m8TPCM"
   storage.additionalHTTPHeaders = ["x-goog-project-id" : "159*******7"]
   return storage
   }()
}

public func uploadAssetToGoogle(resourcePath: String?) {
  if let _resourcePath = resourcePath {
      let fileHandle = NSFileHandle(forReadingAtPath: _resourcePath)
      let uploadParams = GTLUploadParameters(fileHandle: fileHandle, MIMEType: "video/mov")
      var storageObject = GTLStorageObject.object() as GTLStorageObject
      storageObject.name = "12345678"
      let query = GTLQueryStorage.queryForObjectsInsertWithObject(storageObject, bucket: "my-bucket", uploadParameters: uploadParams) as GTLQuery
      var ticket = googleServiceStorage.executeQuery(query) { ticket, object, error in
          if let _error = error {
              println("Error upload file: \(error.localizedDescription) : \(error.localizedFailureReason)")
              return
          }
          println("Upload succeeded")
      }
      ticket.uploadProgressBlock = {ticket, numberOfBytesRead, dataLength in
          println("Ticket: \(ticket)")
          NSLog("read %llu from %llu bytes", numberOfBytesRead, dataLength)
      }
  }

When I call this code I get the following output in the console:

mediaURL type: (Metatype) - file:///Users/Michael/Library/Developer/CoreSimulator/Devices/5895B7FA-41E7-4958-84FD-2C1043CA7CD7/data/Containers/Data/Application/2DD62539-E364-4BE0-A89C-E0DD2827D74B/tmp/trim.FCE68DAD-0FC6-4E2D-8C92-37055A02DD12.MOV

Error upload file: The operation couldn’t be completed. (Login Required) : Optional("(Login Required)")

There is something I am missing, but I can't figure it out. If anyone can help me, it will save me a lot more hair.

回答1:

For Login Required error message try with adding new bucket permission item

ENTITY = User, NAME = allUsers, ACCESS = Writer

Please note: You have to use Server API key not iOS API key

For object upload, you can add GTLStorageObjectAccessControl

GTLStorageObjectAccessControl *objAccessControl = [GTLStorageObjectAccessControl new];
objAccessControl.entity = @"allUsers";
objAccessControl.email = @"xxxxxx-xxxxx@developer.gserviceaccount.com";
objAccessControl.role = @"OWNER";

GTLStorageObject *newObject = [GTLStorageObject object];
newObject.name = @"image.png";
newObject.acl = @[objAccessControl];

Than,

GTLQueryStorage *query = [GTLQueryStorage queryForObjectsInsertWithObject:newObject bucket:kBucketName uploadParameters:uploadParameters];
