准备工作

在开始之前，请确保以下准备工作已完成：

  1. 注册微信公众号：访问微信公众平台官网（），注册并获取相应的AppID和AppSecret。
  2. 设置服务器：准备一个可以运行PHP的服务器环境。
  3. 获取access_token：通过AppID和AppSecret获取access_token，这是与微信服务器通信的凭证。

获取access_token

<?php
$AppID = '你的AppID';
$AppSecret = '你的AppSecret';
$url = "https://api.weixin.qq.com/cgi-bin/token?grant_type=client_credential&appid=$AppID&secret=$AppSecret";

$result = json_decode(file_get_contents($url), true);
$access_token = $result['access_token'];

echo "Access Token: " . $access_token . "\n";
?>

发送文本消息

<?php
$access_token = '你的access_token';
$toUser = '接收者的OpenID';
$fromUser = '发送者的OpenID';
$content = '这是一条测试消息';

$url = "https://api.weixin.qq.com/cgi-bin/message/custom/send?access_token=$access_token";

$data = json_encode([
    'touser' => $toUser,
    'fromuser' => $fromUser,
    'msgtype' => 'text',
    'text' => ['content' => $content]
]);

$result = http_post($url, $data);

echo "发送结果：" . $result . "\n";
?>

发送图片消息

<?php
$access_token = '你的access_token';
$toUser = '接收者的OpenID';
$fromUser = '发送者的OpenID';
$media_id = '上传图片后获得的media_id';

$url = "https://api.weixin.qq.com/cgi-bin/message/custom/send?access_token=$access_token";

$data = json_encode([
    'touser' => $toUser,
    'fromuser' => $fromUser,
    'msgtype' => 'image',
    'image' => ['media_id' => $media_id]
]);

$result = http_post($url, $data);

echo "发送结果：" . $result . "\n";
?>

发送图文消息

<?php
$access_token = '你的access_token';
$toUser = '接收者的OpenID';
$fromUser = '发送者的OpenID';
$media_id = '上传图文消息后获得的media_id';

$url = "https://api.weixin.qq.com/cgi-bin/message/custom/send?access_token=$access_token";

$data = json_encode([
    'touser' => $toUser,
    'fromuser' => $fromUser,
    'msgtype' => 'news',
    'news' => [
        'articles' => [
            [
                'title' => '标题',
                'thumb_media_id' => $media_id,
                'author' => '作者',
                'digest' => '摘要',
                'show_cover_pic' => 1,
                'content' => '内容',
                'content_source_url' => '链接'
            ]
        ]
    ]
]);

$result = http_post($url, $data);

echo "发送结果：" . $result . "\n";
?>
