C# Http请求接口数据的两种方式Get and Post

面向接口编程是一种设计思想,无论用什么语言都少不了面向接口开发思想,在软件开发过程中,常常要调用接口,接下来就是介绍C#调用其它开发商提供的接口进行获取数据,http接口方式获取接口数据。

Get请求数据:

 using (var httpClient = new HttpClient())
            {                
                //get
                var url = new Uri("接口网络地址");
                // response
                var response = httpClient.GetAsync(url).Result;
                var data = response.Content.ReadAsStringAsync().Result;
               return data;//接口调用成功获取的数据
            }

Post请求数据:

using (var httpClient = new HttpClient())
            {             
                //post
                var url = new Uri("接口网络地址");
                var body = new FormUrlEncodedContent(new Dictionary<string, string>
                {
                    { "参数1", "值1"},
                    { "参数2", "值2"},
                    { "参数3", "值3"},
                    { "参数4", "值4"},
                });
                // response
                var response = httpClient.PostAsync(url, body).Result;  
                var data = response.Content.ReadAsStringAsync().Result;
                return data;//接口调用成功数据
            }

  如果接口调用需要传请求头可以使用如下代码设置请求头:

 httpClient.DefaultRequestHeaders.Add("Accept", "application/json");//设置请求头
