Two ways of C# Http request interface data Get and Post

Interface-oriented programming is a design idea. No matter what language is used, the idea of ​​interface-oriented development is indispensable. In the process of software development, the interface is often called. The next step is to introduce C# to call the interface provided by other developers to obtain data. The http interface method Get interface data.

Get request data:

using (var httpClient = new HttpClient())
            {                
                //get
                var url = new Uri("interface network address");
                // response
                var response = httpClient.GetAsync(url).Result;
                var data = response.Content.ReadAsStringAsync().Result;
               return data;//The data obtained by the interface call successfully
            }

Post request data:

using (var httpClient = new HttpClient())
            {             
                //post
                var url = new Uri("interface network address");
                var body = new FormUrlEncodedContent(new Dictionary<string, string>
                {
                    { "parameter1", "value1"},
                    { "parameter2", "value2"},
                    { "parameter 3", "value 3"},
                    { "parameter 4", "value 4"},
                });
                // response
                var response = httpClient.PostAsync(url, body).Result;  
                var data = response.Content.ReadAsStringAsync().Result;
                return data;//Interface call success data
            }

　　If the interface call needs to pass the request header, you can use the following code to set the request header:

httpClient.DefaultRequestHeaders.Add("Accept", "application/json");//Set the request header
