HttpWebRequest 模拟Http请求

在项目中我们往往要模拟Http请求一下是一个。net form程序模拟http请求

 string GetResponse(string url, params string[] parameters)

        {

            WebClient client = new WebClient();

            string returnvalue = string.Empty;

            try

            {

                HttpWebRequest hwr = (HttpWebRequest)HttpWebRequest.Create(url);

                hwr.Timeout = 360000;

                hwr.Method = "POST";

                //获取登录用户的Session 具体会有所改动

                hwr.Headers.Add("Cookie", "JSESSIONID=C2D2336D0EDFFB0502D2A1D90DB8EE39");

                if (parameters!=null)

                {

                    using (Stream reqStream = hwr.GetRequestStream())

                    {

                        foreach (string parameter in parameters)

                        {

                            reqStream.Write(Encoding.GetEncoding("GB2312").GetBytes(parameter), 0, Encoding.GetEncoding("GB2312").GetBytes(parameter).Length);

                        }

                    }

                }

                HttpWebResponse wr = (HttpWebResponse)hwr.GetResponse();

                using (Stream sr = wr.GetResponseStream())

                {

                    StreamReader reader = new StreamReader(sr, Encoding.GetEncoding("GB2312"));

                    returnvalue = reader.ReadToEnd();

                }

            }

            catch (Exception exception)

            {

                MessageBox.Show(exception.Message);

            }

            return returnvalue;

        }

使用

  string requestBody = "model.ringid=852300007566";

            string str = GetResponse("http://61.138.203.62:8080/systemportal/ring/basic/ringfile_update_init.action", requestBody);

          webBrowser1.DocumentText = str;
