In c #, an exception is thrown in the HttpWebRequest request. The basic connection is closed: the connection is accidentally closed,

When using httpWebRequest to simulate a request, sometimes the request is limited by the server and other factors,
When the request appearsBasic Connection closed: An Unexpected error occurred while receivingError
The general cause is that the server cannot establish persistent connection with Internet resources and the http Version.
Make the following simple modification to httpWebRequest to solve the problem:

 

Request. keepAlive = false; // you can specify whether to establish a persistent connection request. protocolVersion = HttpVersion. version10; // There are two http versions, one is 1.0, and the other is 1.1, which is more practical to test and replace.
