Question

我正在使用Go SDK连接到Kinesis Video Streams服务。在发出GetMedia请求时，我收到了以下正文的403回复：

<AccessDeniedException>
  <Message>Unable to determine service/operation name to be authorized</Message>
</AccessDeniedException>

我正在使用LogLevel LogDebugWithHTTPBody来查看此内容，因为SDK需要JSON并接收XML，从而导致SerializationError。

我正在使用Go 1.9.2并尝试使用aws-sdk-go的v1和v2进行此操作，结果相同。

这是我的要求：

POST /getMedia HTTP/1.1
Host: kinesisvideo.us-west-2.amazonaws.com
User-Agent: aws-sdk-go/2.0.0-preview.1 (go1.9.2; darwin; amd64)
Content-Length: 141
Authorization: AWS4-HMAC-SHA256 Credential=AKIAXXXXXXXXXXXXXX/20180112/us-west-2/kinesisvideo/aws4_request, SignedHeaders=content-length;host;x-amz-date, Signature=60c625357b67c64caed32f5a0924882f26ffc776211801e94e7ecae84e7213c2

Accept-Encoding: gzip

{"StartSelector":{"StartSelectorType":"NOW"},"StreamARN":"arn:aws:kinesisvideo:us-west-2:XXXXXXXXXXXXX:stream/StreamTest/XXXXXXXXXXXXX"}

响应：

HTTP/1.1 403 Forbidden
Content-Length: 130
Date: Fri, 12 Jan 2018 01:25:11 GMT

<AccessDeniedException>
  <Message>Unable to determine service/operation name to be authorized</Message>
</AccessDeniedException>

非常感谢任何帮助。

要跟进，我尝试直接发出上面的HTTP请求并添加了Content-Type: application/json标头，现在响应是：

{
    "Output": {
        "__type": "com.amazon.coral.service#UnknownOperationException",
        "message": null
    },
    "Version": "1.0"
}

我找到了解决方案。来自文档，

＆＃34;您必须首先调用GetDataEndpoint API以获取可以向其发送GetMedia请求的端点。＆＃34;

转到AWS SDK“无法确定要授权的服务/操作名称”
