1:Get:
public static string HttpGetJsonAPI(string uri) try HttpWebRequest webRequest = (HttpWebRequest)WebRequest.Create(uri); webRequest.Method = "GET"; webRequest.ContentType = "application/json"; webRequest.Accept = "application/json"; webRequest.Headers.Add("Authorization", GlobalVariable.NowLoginUser.JwtKey); HttpWebResponse webResponse = (HttpWebResponse)webRequest.GetResponse(); StreamReader reader = new StreamReader(webResponse.GetResponseStream(), Encoding.UTF8); String res = reader.ReadToEnd(); reader.Close(); return res.Trim(); catch (Exception ex) return null;
2:Post:
public static string HttpPostJsonAPI(string uri, string parameters,string Type, string token = "") try byte[] bytes = Encoding.UTF8.GetBytes(parameters);//这里需要指定提交的编码 HttpWebRequest webRequest = (HttpWebRequest)WebRequest.Create(uri); webRequest.Method = "POST"; webRequest.ContentType = "application/json"; webRequest.Accept = "application/json"; if (GlobalVariable.NowLoginUser == null) webRequest.Headers.Add("token", ""); else webRequest.Headers.Add("token", GlobalVariable.NowLoginUser.JwtKey); webRequest.ContentLength = bytes.Length; Stream dataStream = webRequest.GetRequestStream(); dataStream.Write(bytes, 0, bytes.Length); dataStream.Close(); HttpWebResponse webResponse = (HttpWebResponse)webRequest.GetResponse(); StreamReader reader = new StreamReader(webResponse.GetResponseStream(), Encoding.UTF8); String res = reader.ReadToEnd(); reader.Close(); return res.Trim(); catch (Exception ex) return null;
3:将获取到的数据转换为相应实体类:
public static List<T> GetData<T>(Dictionary<string, string> dicNamwValue, string FunTitile, EnumWebType enumType) try string strurl = GlobalVariable.WebRemotelyIP + FunTitile;// ; List<T> listPcaSumData = new List<T>(); foreach (var item in dicNamwValue) strurl = strurl + item.Key + "=" + item.Value + "&"; strurl = strurl.Substring(0, strurl.LastIndexOf("&")); string strapi = null; if (enumType == EnumWebType.Get) strapi = HttpGetJsonAPI(strurl); else strapi = HttpPostJsonAPI(strurl, string.Empty, EnumWebType.Post.ToString()); if (strapi != null) JObject json1 = (JObject)JsonConvert.DeserializeObject(strapi); JValue jTotalCount = (JValue)json1[OrigriUserInfo.totalCount]; Type tokenType = json1[OrigriUserInfo.data].GetType(); switch (tokenType.FullName) case "Newtonsoft.Json.Linq.JArray": JArray array = (JArray)json1[OrigriUserInfo.data]; foreach (var jObject in array) listPcaSumData.Add(JsonConvert.DeserializeObject<T>(jObject.ToString())); break; case "Newtonsoft.Json.Linq.JValue": JValue jdata = (JValue)json1[OrigriUserInfo.data]; listPcaSumData.Add(JsonConvert.DeserializeObject<T>(jdata.ToString())); break; return listPcaSumData; else return null; catch (Exception ex) return null;
