c# 写一段程序 向post接口 http://121.36.111.13:8021/otherRoute/getWorkerList 发送json

在C#中，你可以使用HttpClient库来发送POST请求并携带JSON数据。以下是一个简单的示例：

using System;
using System.Net.Http;
using System.Text.Json;

class Program
{
    static async Task Main(string[] args)
    {
        string apiUrl = "http://121.36.111.13:8021/otherRoute/getWorkerList";
        string jsonContent = "{\"key\":\"value\"}"; // 替换为你实际需要的JSON数据

        try
        {
            HttpClient client = new HttpClient();
            HttpContent content = new StringContent(jsonContent, Encoding.UTF8, "application/json");
            HttpResponseMessage response = await client.PostAsync(apiUrl, content);

            if (response.IsSuccessStatusCode)
            {
                Console.WriteLine($"Request successful. Response status code: {response.StatusCode}");
                string responseBody = await response.Content.ReadAsStringAsync();
                Console.WriteLine("Response body:");
                Console.WriteLine(responseBody);
            }
            else
            {
                Console.WriteLine($"Request failed with status code: {response.StatusCode}");
            }
        }
        catch (Exception ex)
        {
            Console.WriteLine($"Error occurred: {ex.Message}");
        }
    }
}

在这个例子中，我们首先创建了一个HttpClient实例，然后设置HTTP请求的内容为JSON字符串，并指定其MIME类型为`application/json`。接着，我们使用PostAsync方法发送POST请求到指定的URL。如果请求成功，我们会读取响应内容并打印出来。
