HttpResponseMessage 的内容为 JSON

在进行网络编程中，我们经常会遇到需要处理返回的HttpResponseMessage的情况。HttpResponseMessage是用于表示HTTP响应的类，其中最重要的属性之一就是Content属性。Content属性可以获取到响应的内容，常见的情况是响应内容为JSON格式的数据。

csharp
HttpResponseMessage response = await client.GetAsync(url);
string jsonContent = await response.Content.ReadAsStringAsync();

json
{
  "name": "John",
  "age": 25,
  "email": "john@example.com"
}

csharp
public class User
{
    public string Name { get; set; }
    public int Age { get; set; }
    public string Email { get; set; }
}

csharp
User user = JsonConvert.DeserializeObject(jsonContent);

csharp
Console.WriteLine("姓名：" + user.Name);
Console.WriteLine("年龄：" + user.Age);

csharp
using System;
using System.Net.Http;
using System.Threading.Tasks;
using Newtonsoft.Json;
public class User
{
    public string Name { get; set; }
    public int Age { get; set; }
    public string Email { get; set; }
}
public class Program
{
    static async Task Main(string[] args)
    {
        HttpClient client = new HttpClient();
        string url = "https://api.example.com/user/1";
        
        HttpResponseMessage response = await client.GetAsync(url);
        string jsonContent = await response.Content.ReadAsStringAsync();
        
        User user = JsonConvert.DeserializeObject(jsonContent);
        
        Console.WriteLine("用户信息");
        Console.WriteLine("姓名：" + user.Name);
        Console.WriteLine("年龄：" + user.Age);
        Console.WriteLine("邮箱：" + user.Email);
    }
}
