我正面临S3的问题。 经过3小时的故障排除(同时我了解了IAM角色并设法创建它们),我试图将fb个人资料图片上传到亚马逊S3。

我的代码:

if let imageData = NSData(contentsOf: NSURL(string: url) as! URL) {

                            let fileName = ProcessInfo.processInfo.globallyUniqueString + ".jpg"
                            let fileURL = NSURL(fileURLWithPath: NSTemporaryDirectory()).appendingPathComponent(fileName)
                            let image = UIImage(data: imageData as Data)
                            let imageData = UIImageJPEGRepresentation(image!, 1.0)!
                            do {
                                try imageData.write(to: fileURL! as URL)
                            } catch _ {
                                self.log.error("Could not write to file.")
                            }

                            let transferManager = AWSS3TransferManager.default()
                            let uploadRequest = AWSS3TransferManagerUploadRequest()
                            uploadRequest?.bucket = "app-files"
                            uploadRequest?.key = "user-data/" + awsId! + "_primary_profile_picture.jpg"
                            uploadRequest?.body = fileURL!

                            transferManager.upload(uploadRequest!).continueWith(executor: AWSExecutor.mainThread(), block: { (task:AWSTask<AnyObject>) -> Any? in

                                if let error = task.error as? NSError {
                                    if error.domain == AWSS3TransferManagerErrorDomain, let code = AWSS3TransferManagerErrorType(rawValue: error.code) {
                                        switch code {
                                        case .cancelled, .paused:
                                            break
                                        default:
                                            print("Error uploading: \(uploadRequest?.key) Error: \(error)")
                                        }
                                    } else {
                                        print("Error uploading: \(uploadRequest?.key) Error: \(error)")
                                    }
                                    return nil
                                }

                                let uploadOutput = task.result
                                print("Upload complete for: \(uploadRequest?.key)")
                                return nil
                            })
                        }

** **问题 我不断从S3获得The request body terminated unexpectedly错误,如下所示:

Error uploading: Optional("user-data/eu-west-1:xxxx-xxxx-xxxx-xxxx-xxxxxxxxxx_primary_profile_picture.jpg") 
Error: Error Domain=com.amazonaws.AWSS3ErrorDomain Code=0 "(null)" 
UserInfo={HostId=XXX, 
Message=The request body terminated unexpectedly, 
Code=IncompleteBody, 
RequestId=1485A0FFBD7819D7}

我不确定出了什么问题,我已经调试了,fileName,fileURL,imageData似乎没问题了

2.5.1 SDK存在错误,我对其进行了一些解释here

基本上,AWSSignature为上传创建了错误的签名......

你有两种方法来解决它:

1)通过明确声明你需要的所有pod来恢复使用2.5.0 :(编辑:我注意到你因为SWIFT问题而无法做到这一点。可能尝试选项2)

pod 'AWSCore', '2.5.0'
pod 'AWSCognito', '2.5.0'
pod 'AWSLambda', '2.5.0'
pod 'AWSSNS', '2.5.0'
pod 'AWSS3', '2.5.0'

2)自己更改代码以解决问题,直到亚马逊修复它。您需要做的就是在AWSCore / Authentication / AWSSignature.m文件中注释掉第783-785行 - 如果您尝试,您应该收到一条文件被锁定的消息,只需将其解锁即可。

if (self.endOfStream) {
    return NO;
}

答案 1 :(得分:0)

确实当前的AWSS3 SDK存在错误。如果您使用的是cocoapods,您可以安装2.5.0(兼容Swift 3):

pod 'AWSS3', '2.5.0'
