Can I use the postman debugging requests a web page address debugging success
this is a postman headers, did not change
Request method is post, the Body parts in the x - WWW - form - unlencoded inside (on the form - data also can appear error)
Then this is the class web page request program

 public static Tuple UrlRequest (string UrlAddress, string RequestMethod, string RequestData=https://bbs.csdn.net/topics/null, string Cookie=null) 
{
Try 
{
GC. Collect (); 
HttpWebRequest request=(HttpWebRequest) WebRequest. Create (UrlAddress); 
Request. AllowAutoRedirect=false; 
Request. The Method=RequestMethod; 
Request. The Timeout=10000; 
If (cookies!=null) 
{
Request. Headers. The Add (" Cookie ", cookies); 
} 
The else 
{
CookieContainer cookie=new CookieContainer (); 
Request. CookieContainer=cookies; 
} 
Request. The ContentType="application/x - WWW - form - urlencoded"; 
If (RequestData!=null) 
{
Stream RequestStream=request. GetRequestStream (); 
Byte [] bytes=Encoding. UTF8. GetBytes (RequestData); 
Request. The ContentLength=bytes. The Length; 
RequestStream. Write (0 bytes, bytes. The Length). 
RequestStream. Close (); 
} 
HttpWebResponse response=(HttpWebResponse) request. The method GetResponse (); 
The string encoding=response. ContentEncoding; 
If (encoding==null | | encoding. The Length & lt; 1) 
{
Encoding="utf-8"; 
} 
StreamReader reader=new StreamReader (response. GetResponseStream (), Encoding, GetEncoding (Encoding)); 
String retString=reader. ReadToEnd (); 
Request. The Abort (); 
Request=null; 
//response. The Close (); 
//response=null; 
Tuple Tup=new Tuple (retString, response); 
Return tup. 
} 
Catch 
{
return null; 
} 
} 

Debug the program execution, will be submitted to the exception: the remote server returns an error: (500) internal server error
Can someone tell me where I went wrong,

CodePudding user response:

Baidu (500) internal server error

CodePudding user response:

Request the interface of the internal handling exceptions, maybe you wrong incoming parameters resulted in the interface when the exception handling, this alignment with interface

CodePudding user response:

Since 500 an internal error, so you directly debugging and see where the error,

Website is certainly no problem, after all, postman can debug successful, this method must be problem of a class, just don't know where is there a problem

interface, I cannot change, the incoming parameters like the postman is the same, the difference is that the postman is key: the form of value, enter a connector, and program class is the key=value, & amp; As a connector,

The program class RequestData travels is username=test& Password=pass

Use Fiddler requests of the network monitoring, and see the difference between two ways
