本篇内容介绍了“HttpRequest Get和Post怎么调用其他页面”的有关知识，在实际案例的操作过程中，不少人都会遇到这样的困境，接下来就让小编带领大家学习一下如何处理这些情况吧！希望大家仔细阅读，能够学有所成！
复制代码 代码如下:
//Get请求方式
private string RequestGet(string Url)
{
string PageStr = string.Empty;//用于存放还回的html
Uri url = new Uri(Url);//Uri类 提供统一资源标识符 (URI) 的对象表示形式和对 URI 各部分的轻松访问。就是处理url地址
try
{
HttpWebRequest httprequest = (HttpWebRequest)WebRequest.Create(url);//根据url地址创建HTTpWebRequest对象
#region 参数设置
httprequest.Method = "get";
//---------------------------------------------设定一些参数（不必要可以）
//httprequest.KeepAlive = false;//持久连接设置为false
//httprequest.ProtocolVersion = HttpVersion.Version11;// 网络协议的版本
//httprequest.Proxy = WebProxy.GetDefaultProxy();//服务器代理
//httprequest.ContentType = "application/x-www-form-urlencoded";//http 头
//httprequest.AllowAutoRedirect = true;
//httprequest.MaximumAutomaticRedirections = 10;
//httprequest.Timeout = 30000;//设定超时十秒（毫秒）
//httprequest.UserAgent = "mozilla/4.0 (compatible; msie 6.0; windows nt 5.1)"; //浏览器
//=================================================
#endregion
HttpWebResponse response = (HttpWebResponse)httprequest.GetResponse();//使用HttpWebResponse获取请求的还回值
Stream steam = response.GetResponseStream();//从还回对象中获取数据流
StreamReader reader = new StreamReader(steam, Encoding.GetEncoding("gb2312"));//读取数据Encoding.GetEncoding("gb2312")指编码是gb2312，不让中文会乱码的
PageStr = reader.ReadToEnd();
reader.Close();
}
catch (Exception e)
{
PageStr += e.Message;
}
return PageStr;
}
复制代码 代码如下:
//Post请求方式，于Get的方式写法相似，所以解释就些少一点了
private string RequestPost(string Url,string Context)//两个参数分别是Url地址和Post过去的数据
{
string PageStr=string.Empty;
Uri url = new Uri(Url);
byte[] reqbytes=Encoding.ASCII.GetBytes(Context);
try
{
HttpWebRequest req = (HttpWebRequest)WebRequest.Create(url);
req.Method = "post";
req.ContentType = "application/x-www-form-urlencoded";
req.ContentLength = reqbytes.Length;
Stream stm = req.GetRequestStream();
stm.Write(reqbytes, 0, reqbytes.Length);
stm.Close();
HttpWebResponse wr = (HttpWebResponse)req.GetResponse();
Stream stream = wr.GetResponseStream();
StreamReader srd= new StreamReader(stream,Encoding.GetEncoding("gb2312"));
PageStr += srd.ReadToEnd();
stream.Close();
srd.Close();
}
catch (Exception e)
{
PageStr += e.Message;
}
return PageStr;
}
复制代码 代码如下:
public string WebClientGet(string url)
{
var client = new WebClient();
client.Headers.Add("user-agent", "Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.2; .NET CLR 1.0.3705;)");
var stream = client.OpenRead(url);
if (stream == null) return "";
var reader = new StreamReader(stream, Encoding.Default);
var result = reader.ReadToEnd();
stream.Close();
reader.Close();
return result;
}
