C#语言

提示

下面示例适用于 .NET 6+ 控制台程序，使用框架内置的 System.Text.Json 和 HttpClient，无需安装第三方包。

# POST 发送（.NET 6+ 最小托管程序）

using System.Text;
using System.Text.Json;

// 使用静态 HttpClient，避免每次请求都创建实例导致 socket 耗尽
using var httpClient = new HttpClient { Timeout = TimeSpan.FromSeconds(10) };

var channelCode = "4d05f4abdb0a0c2a0269900809946903";
var payload = new
{
    head = "测试标题",                          // 必填
    body = "测试内容 " + DateTime.Now,          // 选填，支持换行
    url = ""                                   // 选填：点击跳转链接
};

var json = JsonSerializer.Serialize(payload);
using var content = new StringContent(json, Encoding.UTF8, "application/json");

using var response = await httpClient.PostAsync(
    $"https://www.phprm.com/services/push/send/{channelCode}", content);

var res = await response.Content.ReadAsStringAsync();
Console.WriteLine("推送状态：" + (int)response.StatusCode);
Console.WriteLine(res);

# GET 发送（最简单）

using System.Net;

using var httpClient = new HttpClient();

var channelCode = "4d05f4abdb0a0c2a0269900809946903";
var head = WebUtility.UrlEncode("测试标题");  // 中文必须 UrlEncode
var body = WebUtility.UrlEncode("测试内容");
var url = $"https://www.phprm.com/services/push/trigger/{channelCode}?head={head}&body={body}";

var res = await httpClient.GetStringAsync(url);
Console.WriteLine(res);

# .NET Framework 4.x 写法

老项目没有 using var 和顶层语句时，可以用传统写法（需 NuGet 安装 Microsoft.Net.Http，JSON 可使用 Newtonsoft.Json）：

using System;
using System.Net.Http;
using System.Text;
using System.Threading.Tasks;
using Newtonsoft.Json;

class Program
{
    private static readonly HttpClient httpClient = new HttpClient();

    static async Task Main(string[] args)
    {
        var channelCode = "4d05f4abdb0a0c2a0269900809946903";
        var json = JsonConvert.SerializeObject(new
        {
            head = "测试标题",
            body = "测试内容",
            url = ""
        });

        using (var content = new StringContent(json, Encoding.UTF8, "application/json"))
        using (var response = await httpClient.PostAsync(
            $"https://www.phprm.com/services/push/send/{channelCode}", content))
        {
            var res = await response.Content.ReadAsStringAsync();
            Console.WriteLine("推送状态：" + (int)response.StatusCode);
            Console.WriteLine(res);
        }
    }
}

注意

HttpClient 建议使用单例（静态/using 顶层），不要每次发送都 new HttpClient()，否则高并发下会耗尽 socket。
GET 请求的中文参数必须用 WebUtility.UrlEncode 编码。
