Question

我试图将图像上传到Aws S3存储桶。我试图按照教程进行操作，并且我收到错误说“＃34;返回ENOTCONN，因为协议尚未设置。＆＃34;我是swift的新手，我也无法理解错误发生的原因。我上传的S3代码如下：

 let uploadRequest = AWSS3TransferManagerUploadRequest()
 uploadRequest?.body = url!
 uploadRequest?.key = remoteFileName
 uploadRequest?.bucket = S3BucketName
 uploadRequest?.contentType = "image/" + ext

 let transferManager = AWSS3TransferManager.default()

 // Perform Upload
 transferManager.upload(uploadRequest!).continueWith(block: { (task:AWSTask<AnyObject>) -> AnyObject! in

      if let error = task.error{
                print("error \(error.localizedDescription)")
            }

      if task.result != nil {
            let url = AWSS3.default().configuration.endpoint.url
            let publicURL = url?.appendingPathComponent((uploadRequest?.bucket!)!).appendingPathComponent((uploadRequest?.key!)!)
               print("Uploaded to:\(publicURL)")
            }
             return nil
 })

我的S3位于ap-south-1和cognito pool id in us-west-2。我想这就是创造问题。有没有办法解决问题，而不在us-west-2中创建另一个存储桶。我收到以下错误：

如果未将身份验证池设置为进行身份验证，您希望存储桶策略有点像这样：注意 Principal 和 Action 值

另外，您使用AWSS3TransferManagerUploadRequest是否有任何特殊原因？如果策略无法解决您的问题，您可以使用以下代码AWSS3TransferUtilityUploadExpression，它以异步方式以块的形式发送数据。

   let expression = AWSS3TransferUtilityUploadExpression()

    expression.progressBlock = progressBlock

    transferUtility.uploadData(UIImagePNGRepresentation(imageNew!)!,
                               bucket: "bucket-name",
                               key: (imgName.removeWhitespace()),
                               contentType: "image/png",
                               expression: expression,
                               completionHandler: completionHandler).continueWith { (task) -> AnyObject! in
                                                if let error = task.error {
                                                    print("Error: \(error.localizedDescription)")
                                                }

                                                if let _ = task.result {
                                                    print("Upload Starting!")
                                                    // Do something with uploadTask.
                                                }

                                                return nil;
                }

返回ENOTCONN错误
