iOS将文件上传到Google Cloud Storage-获取401:“需要登录" [英] iOS Upload file to Google Cloud Storage - getting 401: 'Login Required'

问题描述

我在弄清楚如何将文件上传到公共访问存储桶到Cloud Storage时遇到麻烦.

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

1. 我已经设置了存储桶，并将所有用户的ACL设置为READ和WRITE.
2. 我已启用Cloud Storage JSON API和Cloud Storage API.
3. 我为浏览器应用程序创建了一个API密钥，该密钥允许任何引荐来源网址.

这是我在Swift中的代码:

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)
      }
  }

调用此代码时，我将在控制台中获得以下输出:

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)")

我缺少一些东西，但是我无法弄清楚.如果有人可以帮助我，它将为我节省很多头发.

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.

推荐答案

对于需要登录错误消息，尝试添加新的存储桶权限项

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

ENTITY = User, NAME = allUsers, ACCESS = Writer

请注意:您必须使用Server API key而不是iOS API key

对于对象上传，您可以添加GTLStorageObjectAccessControl

For object upload, you can add GTLStorageObjectAccessControl

GTLStorageObjectAccessControl *objAccessControl = [GTLStorageObjectAccessControl new];
objAccessControl.entity = @"allUsers";
objAccessControl.email = @"[e-mail]";
objAccessControl.role = @"OWNER";

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

比

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