在C#中,您可以使用JsonConvert类将对象转换为JSON字符串,并将其作为响应发送回客户端。以下是一个示例代码片段,演示如何发送JSON响应:
using System;
using System.Net;
using System.Text;
using Newtonsoft.Json;
class Program
{
static void Main()
{
var data = new { Name = "John", Age = 30 };
var json = JsonConvert.SerializeObject(data);
HttpListener listener = new HttpListener();
listener.Prefixes.Add("http://localhost:8080/");
listener.Start();
Console.WriteLine("Listening for requests...");
while (true)
{
HttpListenerContext context = listener.GetContext();
HttpListenerRequest request = context.Request;
HttpListenerResponse response = context.Response;
byte[] buffer = Encoding.UTF8.GetBytes(json);
response.ContentType = "application/json";
response.ContentLength64 = buffer.Length;
response.OutputStream.Write(buffer, 0, buffer.Length);
response.Close();
}
}
}
在上面的示例中,我们创建了一个包含名称和年龄属性的匿名对象,并将其转换为JSON字符串。然后我们创建了一个HttpListener实例来监听HTTP请求。当有请求到达时,我们将JSON字符串作为响应发送回客户端,并设置适当的Content-Type为"application/json"。
