1.WinFrom调用webapi接口方法

最近项目要在winfrom项目中调用webAPI，故在网上查找资料，找到了一个WinFrom调用webapi接口的通用方法，关键代码：

 #region WinFrom调用webapi接口通用方法         private async Task InvokeWebapi(string url, string api, string type, Dictionary dics)         {             string result = string.Empty;             HttpClient client = new HttpClient();             client.DefaultRequestHeaders.Add("authorization", "Basic YWRtaW46cGFzc3dvcmRAcmljZW50LmNvbQ==");//basic编码后授权码             client.BaseAddress = new Uri(url);              client.Timeout = TimeSpan.FromSeconds(510);              if (type.ToLower() == "put")             {                 HttpResponseMessage response;                 //包含复杂类型                 if (dics.Keys.Contains("input"))                 {                     if (dics != null)                     {                         foreach (var item in dics.Keys)                         {                             api = api.Replace(item, dics[item]).Replace("{", "").Replace("}", "");                         }                     }                     var contents = new StringContent(dics["input"], Encoding.UTF8, "application/json");                     response = client.PutAsync(api, contents).Result;                     if (response.IsSuccessStatusCode)                     {                         result = await response.Content.ReadAsStringAsync();                         return result;                     }                     return result;                 }                  var content = new FormUrlEncodedContent(dics);                 response = client.PutAsync(api, content).Result;                 if (response.IsSuccessStatusCode)                 {                     result = await response.Content.ReadAsStringAsync();                     return result;                 }             }             else if (type.ToLower() == "post")             {                 var content = new FormUrlEncodedContent(dics);                  HttpResponseMessage response = client.PostAsync(api, content).Result;                 if (response.IsSuccessStatusCode)                 {                     result = await response.Content.ReadAsStringAsync();                     return result;                 }             }             else if (type.ToLower() == "get")             {                 HttpResponseMessage response = client.GetAsync(api).Result;                  if (response.IsSuccessStatusCode)                 {                     result = await response.Content.ReadAsStringAsync();                     return result;                 }             }             else             {                 return result;             }             return result;         }          #endregion   

2.应用实例

创建一个名为callWebAPI的窗体项目，在窗体加两个textBox。下面实例主要是调用webAPI的方法获取数据存为json格式，然后将json格式的数据从文件中读取出来。调用代码如下：

 private async void callWebAPI_Load(object sender, EventArgs e)         {             #region 调用webapi并存为json格式文件             string api = "";             string url = "http://10.3.11.2/SimploWebApi/api/LASER_System/LASER_GetLineShowConfig?typeString=2";             Dictionary dics = new Dictionary();             Task task = InvokeWebapi(url, api, "post", dics);             string result = task.Result;             //textBox1.Text = result;             if (result != null)             {                 JObject jsonObj = null;                 jsonObj = JObject.Parse(result);                 DataInfo info = new DataInfo();                 info.statusCode = Convert.ToInt32(jsonObj["statusCode"]);                 //info.message = jsonObj["message"].ToString();                 if (info.statusCode == 0)                 {                     JArray jlist = JArray.Parse(jsonObj["Data"].ToString());                     string json = JsonConvert.SerializeObject(jlist, Formatting.Indented);                     //File.WriteAllText("Standard.json", json);//将数据存为json格式                     for (int i = 0; i < jlist.Count; ++i)  //遍历JArray                       {                                              JObject tempo = JObject.Parse(jlist[i].ToString());                         textBox1.Text += tempo["line"].ToString();                                         }                 }             }             #endregion              #region  获取json文件数据             // 读取JSON文件内容             string jsonFilePath = "Standard.json";             string jsons = File.ReadAllText(jsonFilePath);              // 反序列化JSON到对象             Standard standard = JsonConvert.DeserializeObject(jsons);             textBox2.Text = standard.line + "," + standard.linePlace;             #endregion          } 

以上实例还需建立DataInfo类和Standard类

DataInfo类

DataInfo info = new DataInfo();

 public class DataInfo     {         public int statusCode { get; set; }         public string message { get; set; }          }

Standard类

 Standard standard = JsonConvert.DeserializeObject(jsons);

  public class Standard     {         public string line { get; set; }         public string linePlace { get; set; }          }

以上实例用了json，所以需要引用Newtonsoft.Json.dll（具体引用方法见以前文章）

using Newtonsoft.Json;

Standard.json文件

{     "line": "B10",     "linePlace": "CQ_1",   }

补充：

get的传参方式

            string api = "";             string sWo = "1025";                       string url = "http://10.1.1.1/api/MES/API_GetLaserAOIParm?sWo=" + sWo + "";             Dictionary dics = new Dictionary();                       Task task = InvokeWebapi(url, api, "post", dics);             string result = task.Result;

post的传参方式

            string api = "";             string sWo = "1025";                       string url = "http://10.1.1.1/api/MES/API_GetLaserAOIParm";             Dictionary dics = new Dictionary();             dics = new Dictionary             {                 { "sWo", sWo },                         };             Task task = InvokeWebapi(url, api, "post", dics);             string result = task.Result;
