c# - 从我的 Web 服务读取 Http POST 正文内容？ (.net 3.5)

Question

好吧，这让我抓狂。我正在将 Amazon SNS 集成到我拥有的 Web 服务中。 Amazon 只是将带有一堆 json 内容的 HTTP post 发送到我指定的 url。我只是无法访问它。

[WebMethod]
[ScriptMethod(ResponseFormat = ResponseFormat.Json)]
public void HandleBounce()
{
    notification = //I need to put the JSON content into here
}

Amazon 只需访问 url ( http://test.com/webservice.aspx/HandleBounce )。该方法被正确调用。我只需要获取它在帖子中发送的数据。我该怎么做？

编辑:

我最初尝试使用

[WebMethod]
[ScriptMethod(ResponseFormat = ResponseFormat.Json)]
public void HandleBounce(string json)
{
    notification = //I need to put the JSON content into here
}

但是当我这样做时，这个方法根本就不会被调用。至少当我删除参数时，该方法有效。

这是亚马逊网站关于他们向我发送的请求:

Answer 1

使用以下调整，我能够解决问题:

    [WebMethod]
    [ScriptMethod(ResponseFormat = ResponseFormat.Json)]
    public void HandleBounce() //This method is called from Amazon Simple Notification Service when we receive a bounce.
    {
        string notification = "";
        using (var stream = new MemoryStream())
        {
            var request = HttpContext.Current.Request;
            request.InputStream.Seek(0, SeekOrigin.Begin);
            request.InputStream.CopyTo(stream);
            notification = Encoding.UTF8.GetString(stream.ToArray());
        }
    }
