后台访问接口

一、无法直接通过接口获取数据，需要转接口获取数据

ContentType ：application/x-www-form-urlencoded：输入值为字符串格式
ContentType：application/json：输入值为json格式

第1种：输入字典类型转json类型：

1 字典：Dictionary<string, object> parameters =new Dictionary<string, object>（）；
 2 parameters.add（“key”,”value”）；
 3 string mm = GetPage("http://21.254.198.70:803/api/healthLogin", parameters);
 4 /// <summary>
 5         /// 指定Post地址 
 6         /// </summary>
 7         /// <param name="url">请求后台地址</param>
 8         /// <returns></returns>
 9         public static string Post(string url, Dictionary<string, object> parameters)
10         {
11             try
12             { 
13                 string jsonString = JsonConvert.SerializeObject(parameters);
14                 HttpWebRequest request = (HttpWebRequest)WebRequest.Create(url);
15                 request.Method = "POST";
16                 request.ContentType = "application/json"; 
17                 using (StreamWriter dataStream = new StreamWriter(request.GetRequestStream()))
18                 {
19                     dataStream.Write(jsonString);
20                     dataStream.Close();
21                 }
22                 HttpWebResponse response = (HttpWebResponse)request.GetResponse();
23                 string encoding = response.ContentEncoding;
24                 if (encoding == null || encoding.Length < 1)
25                 {
26                     encoding = "UTF-8"; //默认编码  
27                     }
28                 StreamReader reader = new StreamReader(response.GetResponseStream(), Encoding.GetEncoding(encoding));
29                 var retString = reader.ReadToEnd();
30                 return Regex.Unescape(retString); //处理返回的字符比如unicode转为中文
31             }
32             catch (Exception ex)
33             {
34                 throw ex;
35             }
36         }

第2种：输入字符串类型转json类型：

1 string mm = GetPage("http://21.254.198.70:803/api/healthLogin", "{\"phone\":\"" + phone + "\",\"code\":\"" + code + "\"}");
 2 
 3 public string GetPage(string posturl, string postData)
 4         {
 5             Stream outstream = null;
 6             Stream instream = null;
 7             StreamReader sr = null;
 8             HttpWebResponse response = null;
 9             HttpWebRequest request = null;
10             Encoding encoding = Encoding.UTF8;
11             byte[] data = encoding.GetBytes(postData);
12             try
13             {
14                 request = WebRequest.Create(posturl) as HttpWebRequest;
15                 CookieContainer cookieContainer = new CookieContainer();
16                 request.CookieContainer = cookieContainer;
17                 request.AllowAutoRedirect = true;
18                 request.Method = "POST";
19                 request.ContentType = "application/json";
20                 request.ContentLength = data.Length;
21                 outstream = request.GetRequestStream();
22                 outstream.Write(data, 0, data.Length);
23                 outstream.Close();
24                 response = request.GetResponse() as HttpWebResponse;
25                 instream = response.GetResponseStream();
26                 sr = new StreamReader(instream, encoding);
27                 string content = sr.ReadToEnd();
28                 string err = string.Empty;
29                 return content;
30             }
31             catch (Exception ex)
32             {
33                 string err = ex.Message;
34                 return string.Empty;
35             }
36         }

二、直接过去数据

[HttpPost]
        public string data(string url, object vo) {  //传入接口连接和对象类型的参数
            string request = JsonConvert.SerializeObject(vo);//将对象参数转化为json格式
            IDictionary<string, string> keyValuePairs = new Dictionary<string, string>();
            keyValuePairs.Add("stbid", "admin2");
            keyValuePairs.Add("token", "9e72b676c19b455fadc5e4b484dbc9ba");//定义两个参数，给两个参数赋值
            var data = Utils.HttpUtil.GetResponseData(url, request, "POST", "application/json", null, keyValuePairs);
            return data;
        }
