使用iOS Swift将带有额外参数的文件上载到AWS S3

Question

就像常规的HTTP POST请求一样。我们可以添加无限参数作为表单数据。使用iOS AWS S3 SDK上传时怎么样？

我的iOS功能

let uploadRequest            = AWSS3TransferManagerUploadRequest();
uploadRequest?.body          = NSURL(string: "file://\(path)") as URL!;
uploadRequest?.key           = "file_name";
uploadRequest?.bucket        = aws_s3_bucket_path;
uploadRequest?.contentType   = "image/" + file_extension;

有什么办法可以添加更多参数发送到我的Lambda函数吗？

您可以add extra parameters向metaData提出请求。

let uploadRequest            = AWSS3TransferManagerUploadRequest();
uploadRequest?.body          = NSURL(string: "file://\(path)") as URL!;
uploadRequest?.key           = "file_name";
uploadRequest?.bucket        = aws_s3_bucket_path;
uploadRequest?.contentType   = "image/" + file_extension;
uploadRequest?.metadata      = ["PhotoTitle" : " testName", "PhotoCaption" : "TestCaption", "UserName" : "TestName", "UserAge" : "TestAge"]
