HttpRequest Get和Post调用其他页面的方法


            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;        }
