麻烦大虾们帮忙提供下 ：asp.net C# 在后台分别用Get 和 post 模式调用Json 接口的方法代码呗，谢谢·~~

是用 get 方式 和post 方式调用接口代码 ，接口返回的是json格式

无非就是后台调用接口然后数据如是直接是JSON就好说，不是的的话你需要拆分解析自己组合成JSON格式 返回到前面在显示出来之类。 参考 http://blog.csdn.net/smartsmile2012/article/details/17220413

HttpContent content = new StringContent(parametersJson) {
        Headers = { ContentType = new MediaTypeHeaderValue("application/json") }
    };
    HttpClient client = new HttpClient {
        BaseAddress = new Uri(host)
    };
    client.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/json"));
    return client.PostAsync(requestPath, content).Result;

我找了2个方法，并测试成功，供大家参考： //get方法调用接口获取json文件内容 public void GetFunction() { string serviceAddress = "http://222.111.999.444:8687/tttr/usercrd/12/b7e50cb45a?userid=9999"; HttpWebRequest request = (HttpWebRequest)WebRequest.Create(serviceAddress); request.Method = "GET"; request.ContentType = "text/html;charset=UTF-8"; HttpWebResponse response = (HttpWebResponse)request.GetResponse(); Stream myResponseStream = response.GetResponseStream(); StreamReader myStreamReader = new StreamReader(myResponseStream, Encoding.UTF8); string retString = myStreamReader.ReadToEnd(); myStreamReader.Close(); myResponseStream.Close(); Response.Write(retString); } ////post方法调用接口获取json文件内容 public void PostFunction() { string serviceAddress = "http://222.111.999.444:8687/tttr/usercrd/uuu/12/dfd7e4"; HttpWebRequest request = (HttpWebRequest)WebRequest.Create(serviceAddress); request.Method = "POST"; request.ContentType = "application/json"; string strContent = @"{ ""mmmm"": ""89e"",""nnnnnn"": ""0101943"",""kkkkkkk"": ""e8sodijf9""}"; using (StreamWriter dataStream = new StreamWriter(request.GetRequestStream())) { dataStream.Write(strContent); dataStream.Close(); } HttpWebResponse response = (HttpWebResponse)request.GetResponse(); string encoding = response.ContentEncoding; if (encoding == null || encoding.Length < 1) { encoding = "UTF-8"; //默认编码 } StreamReader reader = new StreamReader(response.GetResponseStream(), Encoding.GetEncoding(encoding)); string retString = reader.ReadToEnd(); //解析josn JObject jo = JObject.Parse(retString); Response.Write(jo["message"]["mmmm"].ToString()); }

是get /post　获取／提交　ｊｓｏｎ数据　还是？

[於黾]

JSON不是一种数据格式吗 它是什么接口?

[娃都会打酱油了]

var httpClient = new HttpClient();
httpClient.GetAsync
httpClient.PostAsync

[宝_爸]

json是数据格式。 你说的是Restful API?

我试了不行啊，你那边确定没问题吗？
