在WebException中,我看不到GetResponse的主体。这是我在C#中的代码:
try {
return GetResponse(url + "." + ext.ToString(), method, headers, bodyParams);
} catch (WebException ex) {
switch (ex.Status) {
case WebExceptionStatus.ConnectFailure:
throw new ConnectionException();
case WebExceptionStatus.Timeout:
throw new RequestTimeRanOutException();
case WebExceptionStatus.NameResolutionFailure:
throw new ConnectionException();
case WebExceptionStatus.ProtocolError:
if (ex.Message == "The remote server returned an error: (401) unauthorized.") {
throw new CredentialsOrPortalException();
}
throw new ProtocolErrorExecption();
default:
throw;
}
我看到标题,但看不到正文。这是来自Wireshark的请求输出:

是否可以通过某种方式在WebException中查看消息文本?谢谢。
您是否尝试过(HttpWebResponse)we.Response; 您捕获的WebException在哪里“我们”?

throw ex;
而是简单地使用throw;
(在默认情况下)。另外(如果需要),我会将原始WebException放入自定义Exceptions的InnerException中(通过适当的构造函数)。
