Web-Web/Json的请求与返回

引用Dll：Newtonsoft.Json.dll

1.创建Url

  Url组成                            主机名           端口号                                              路径                                      参数

string strUrl = "http://192.199.101.101:9081/"+ string.Format("/Collect/GetProcessData?sessionId={0}&lineNo={1}", "123", "", "32");

2.创建Web请求并设置参数(http://www.cnblogs.com/armyfai/p/3889980.html)

HttpWebRequest request = WebRequest.Create(strUrl) as HttpWebRequest;

request.Method = "GET";
request.UserAgent = "Mozilla/4.0";
request.CookieContainer = cookie;
request.KeepAlive = true;
request.Timeout = 1000;

3.获取Jsion数据并转换为Hashtable

//获取服务器返回的资源

response = (HttpWebResponse)request.GetResponse()

//将请求返回内容转换为StreamReader

StreamReader reader = new StreamReader(response.GetResponseStream(), Encoding.UTF8)

//将StreamReader转换为String

String jsonText = reader.ReadToEnd();

//将string转换为Hashtable

 Hashtable hstJsonText= JsonConvert.DeserializeObject(jsonText, typeof(Hashtable)) as Hashtable;
