To create a custom HTTP handler, you create a class that implements the IHttpHandler interface to create a synchronous handler. Alternatively, you can implement IHttpAsyncHandler to create an asynchronous handler. Both handler interfaces require that you implement the IsReusable property and the ...
WinHTTP provides both a C API as well as a COM API. The C API is naturally harder to use at first, but with a little help from C++ it provides a very powerful and flexible API for building HTTP clients. It also provides both synchronous and asynchronous programming models. I'm going ...
The asynchronous task. Remarks To create a custom handler for an asynchronous task, override the ProcessRequestAsync method. This method stores in the task it returns all non-usage exceptions that the method's synchronous counterpart can throw. If an exception is stored into the returned task, th...

x of the Microsoft®.NET Framework, HttpWebRequest never makes synchronous requests. What do I mean by that? Take a look at the code for HttpWebRequest.GetResponse as coded in the Shared Source CLI (SSCLI), shown here omitting the code that checks to see if the response w...
A synchronous HttpHandler implements theSystem.Web.IHttpHandlerinterface. An asynchronous HttpHandler implements theSystem.Web.IHttpAsyncHandlerinterface. TheSystem.Web.IHttpAsyncHandlerinterface inherits fromSystem.Web.IHttpHandler. Both of these interfaces require you to implement theProcessRequestmethod and theIs...
The GetResponse method makes a synchronous request to the resource specified in the RequestUri property and returns an HttpWebResponse that contains the response object. The response data can be received by using the stream returned by GetResponseStream. If the response object or the response strea...
This method stores in the task it returns all non-usage exceptions that the method's synchronous counterpart can throw. If an exception is stored into the returned task, that exception will be thrown when the task is awaited. Usage exceptions, such as ArgumentException, are still thrown synchro...
UnlikeHttpURLConnection, HTTP Client provides synchronous and asynchronous request mechanisms. 与HttpURLConnection不同,HTTP 客户端提供同步和异步请求机制。 The API consists of three core classes: API 由三个核心类组成: HttpRequestrepresents the request to be sent via theHttpClient. ...
