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 Taskstring InvokeWebapi(string url, string api, string type, Dictionarystring, string 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?typeString2;Dictionarystring, string dics new Dictionarystring, string();Taskstring 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.DeserializeObjectStandard(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.DeserializeObjectStandard(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 ;Dictionarystring, string dics new Dictionarystring, string(); Taskstring 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;Dictionarystring, string dics new Dictionarystring, string();dics new Dictionarystring, string{{ sWo, sWo }, };Taskstring task InvokeWebapi(url, api, post, dics);string result task.Result;
