本文介绍了引发WebException如何获得与身体整体的反应?的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!

问题描述

在引发WebException我看不到的GetResponse的身体。这是我的code在C#中:

  {尝试
  返回的GetResponse(。网址++ ext.ToString(),方法,标头,bodyParams);
}赶上(引发WebException前){
    开关(ex.Status){
      案例WebExceptionStatus.ConnectFailure:
         抛出新ConnectionException();
     案例WebExceptionStatus.Timeout:
         抛出新RequestTimeRanOutException();
     案例WebExceptionStatus.NameResolutionFailure:
         抛出新ConnectionException();
     案例WebExceptionStatus.ProtocolError:
          如果(ex.Message ==远程服务器返回错误:(401)未经授权。){
              抛出新CredentialsOrPortalException();
          }
          抛出新ProtocolErrorExecption();
     默认:
          扔;
    }

我看到标题,但我没有看到尸体。这是Wireshark的输出要求:

是否有可能以某种方式看到引发WebException消息文本?
谢谢你。


解决方案

  VAR RESP =新的StreamReader(ex.Response.GetResponseStream())为ReadToEnd()。动态的obj = JsonConvert.DeserializeObject(RESP);
VAR messageFromServer = obj.error.message;

In WebException I cannot see body of GetResponse. This is my code in C#:

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;
    }

I see header but I don't see body. This is output from Wireshark for the request:

POST /api/1.0/authentication.json HTTP/1.1    
Content-Type: application/x-www-form-urlencoded    
Accept: application/json    
Host: nbm21tm1.teamlab.com

Connection: Keep-Alive

Content-Length: 106    
Content-Type: application/json; charset=UTF-8    
Server: Microsoft-IIS/7.5    
X-AspNet-Version: 2.0.50727    
X-Powered-By: ASP.NET    
X-Powered-By: ARR/2.5

Connection: close    

{"count":0,"startIndex":0,"status":1,"statusCode":500,"error":{"message":"Invalid username or password."}}

Is it possible somehow to see the message text in WebException? Thank you.

解决方案

var resp = new StreamReader(ex.Response.GetResponseStream()).ReadToEnd();

dynamic obj = JsonConvert.DeserializeObject(resp);
var messageFromServer = obj.error.message;
