C# 从我的web服务读取Http POST正文内容？（.net 3.5）

好吧，这让我快发疯了。我正在将Amazon SNS集成到我拥有的web服务中。Amazon只需向我指定的url发送一个包含大量json内容的HTTP post。我就是无法访问它

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

Amazon只需访问url（）。正在正确调用该方法。我只需要获取它在邮件中发送的数据。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
}

但是当我这样做的时候，这个方法根本就没有被调用过。至少当我删除该参数时，该方法是有效的

编辑2：

这是亚马逊网站上关于他们向我发送的请求：

通过以下调整，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());
        }
    }

让您的方法接受string类型的参数并将其称为json。调试您的应用程序并让我们知道发生了什么。可能是@Maritim的重复，我最初尝试这样做，但当我有一个字符串参数时，它根本不会调用该方法。不幸的是，由于请求是从Amazon发送的，我不知道响应是什么，但我想参数不是预期的或使用的。您有任何类型的请求可以检查吗？我怀疑post请求的内容类型可能不是您所期望的。@Maritim，我已将他们发送的假定请求添加到主要问题中。我注意到他们将类型编码为文本，而不是json。我需要做些不同的事情来处理吗？
