我就废话不多说了，大家还是直接看代码吧~

补充：C#后台调用Http外网接口（GET, POST）
1.get方法调用接口获取json文件内容

这个太复杂了 突然发现个简单的：

using (var client = new WebClient()){ client.Encoding = Encoding.UTF8; string serviceAddress = urlappend + "cloud/device/data/getErrorData?appId=" + appid + "&accessToken=" + accessToken + "×tamp=" + time + "&deviceIds=" + deviceIds; var data = client.DownloadString(serviceAddress); var obj = JsonConvert.DeserializeObject<JObject>(data);}//obj就是返回数据的对象 |
2.post方法调用接口获取json文件内容

以上为个人经验，希望能给大家一个参考，也希望大家多多支持服务器之家。如有错误或未考虑完全的地方，望不吝赐教。
