如何在ThinkPHP中实现微信公众号自定义菜单链接功能？

在ThinkPHP中实现微信公众号自定义菜单链接功能，可以按照以下步骤进行：

1. 在config目录下的wechat.php文件中添加以下配置信息：

return [
    "app_id" => "your_app_id",
    "secret" => "your_secret",
    "token" => "your_token",
    "aes_key" => "your_aes_key",
    "oauth" => [
        "scopes" => ["snsapi_userinfo"],
        "callback" => "/index.php/index/callback",
    ],
    "payment" => [
        "merchant_id" => "your_merchant_id",
        "key" => "your_key",
        "cert_path" => "your_cert_path",
        "key_path" => "your_key_path",
        "notify_url" => "your_notify_url",
    ],
    "menu" => [
        "button" => [
            [
                "type" => "view",
                "name" => "菜单名称1",
                "url" => "http://www.example.com",
            ],
            [
                "type" => "view",
                "name" => "菜单名称2",
                "url" => "http://www.example.com",
            ],
            [
                "name" => "菜单名称3",
                "sub_button" => [
                    [
                        "type" => "view",
                        "name" => "子菜单名称1",
                        "url" => "http://www.example.com",
                    ],
                    [
                        "type" => "view",
                        "name" => "子菜单名称2",
                        "url" => "http://www.example.com",
                    ],
                ],
            ],
        ],
    ],
];

2. 在控制器中定义回调方法，并在方法中获取用户信息：

public function callback()
{
    $app = Factory::officialAccount(config("wechat"));
    $oauth = $app->oauth;
    $user = $oauth->user();
    session("wechat_user", $user->toArray());
    $targetUrl = session("target_url") ? session("target_url") : "/";
    header("location:" . $targetUrl);
}

3. 在视图文件中使用自定义菜单：

<script type="text/javascript">
    var appId = "<?php echo $wechatConfig["app_id"]; ?>";
    var redirectUrl = encodeURIComponent("<?php echo $callbackUrl; ?>");
    var targetUrl = encodeURIComponent("<?php echo $targetUrl; ?>");
    var state = "<?php echo $state; ?>";
    var url = "https://open.weixin.qq.com/connect/oauth2/authorize?appid=" + appId + "&redirect_uri=" + redirectUrl + "&response_type=code&scope=snsapi_userinfo&state=" + state + "#wechat_redirect";
    window.location.href = url;
</script>

4. 在公众号管理后台中配置自定义菜单，菜单链接填写自定义链接即可。

以上就是在ThinkPHP中实现微信公众号自定义菜单链接功能的基本步骤，代码仅供参考。
