C# 发送Http请求 - WebClient类

Posted 2020-07-27 roucheng

WebClient位于System.Net命名空间下，通过这个类可以方便的创建Http请求并获取返回内容。

一、用法1 - DownloadData

string uri = "http://hovertree.top/";

WebClient wc = new WebClient();

Console.WriteLine("Sending an HTTP GET request to " + uri);

byte[] bResponse = wc.DownloadData(uri);

string strResponse = Encoding.ASCII.GetString(bResponse);

Console.WriteLine("HTTP response is: ");

Console.WriteLine(strResponse);

// 何问起

二、用法2 - OpenRead 

string uri = "http://hovertree.net";

WebClient wc = new WebClient();

Console.WriteLine("Sending an HTTP GET request to " + uri);

Stream st = wc.OpenRead(uri);

StreamReader sr = new StreamReader(st);

string res = sr.ReadToEnd();

sr.Close();

st.Close();

Console.WriteLine("HTTP Response is ");

Console.WriteLine(res);
// 何问起
