Minio 与 iOS AWS S3 开发工具包 SignatureDoesNotMatch

Question

我有一个 iOS 应用程序可以上传/下载到亚马逊的 S3。我想用我自己的 Minio 云替换 Amazon 的 S3。

我按照此处https://github.com/minio/minio 的快速教程进行了操作，并且我在本地主机上运行了 Minio，我可以使用 s3cmd (https://docs.minio.io/docs/s3cmd-with-minio) 放置文件。

很遗憾，我无法让它在我的 iOS 应用中运行。

我正在使用 AWS SDK v2.4.16，因此我可以更改终端节点并将其设为我的本地主机 (http://my-imac.local:9000)，并更新了我的访问密钥和密钥，但我收到 SignatureDoesNotMatch 错误：“我们的请求签名计算的与您提供的签名不匹配。请检查您的密钥和签名方法。”。

指向我的本地服务器：

AWSEndpoint *minioEndpoint = [[AWSEndpoint alloc] initWithURLString:@"http://my-imac.local:9000"];
AWSServiceConfiguration *configuration = [[AWSServiceConfiguration alloc] initWithRegion:region 
        endpoint:minioEndpoint 
        credentialsProvider:credentialProvider];
[AWSS3 registerS3WithConfiguration:configuration forKey:s3RegionString];

这是我在本地主机上得到的：

在 iOS 端：

请求头是：

{
    Authorization = "AWS4-HMAC-SHA256 Credential=LNTXV0YMMZ9SY7MD0ACZ/20170410/us-east-1/s3/aws4_request, SignedHeaders=content-length;content-type;host;user-agent;x-amz-date, Signature=454c8bad35bdd3a15a08c9bf555fc69f1d5c0dabad78a474eabd4d844ca69aef";
    "Content-Length" = 282416;
    "Content-Type" = "application/octet-stream";
    Host = "my-imac.local";

请替换accessKey、secretKey和url，根据需要更改区域，服务必须设置为.S3

(AWSS3在url中输入xxxx:9000会自动删除端口号，目前只支持不带端口的完整url，所以请确保你有一个到端口9000的域映射，你可能需要参考这个Setup Nginx proxy with Minio Server)

let accessKey = "XXXXXXX"
let secretKey = "XXXXXXX"

let credentialsProvider = AWSStaticCredentialsProvider(accessKey: accessKey, secretKey: secretKey)
let configuration = AWSServiceConfiguration(region: .USEast1, endpoint: AWSEndpoint(region: .USEast1, service: .S3, url: URL(string:"XXXXXX")),credentialsProvider: credentialsProvider)

AWSServiceManager.default().defaultServiceConfiguration = configuration

let S3BucketName = "images"
let remoteName = "test.jpg"
let fileURL = URL(fileURLWithPath: NSTemporaryDirectory()).appendingPathComponent(remoteName)
let image = UIImage(named: "test")
let data = UIImageJPEGRepresentation(image!, 0.9)
do {
    try data?.write(to: fileURL)
}
catch {}

let uploadRequest = AWSS3TransferManagerUploadRequest()!
uploadRequest.body = fileURL
uploadRequest.key = remoteName
uploadRequest.bucket = S3BucketName
uploadRequest.contentType = "image/jpeg"
uploadRequest.acl = .publicRead

let transferManager = AWSS3TransferManager.default()

transferManager.upload(uploadRequest).continueWith { (task: AWSTask<AnyObject>) -> Any? in
  ...
}
