php版微信开发主动发送实例

为了方便调试用CLI方式作测试，记得代码中替换你的appid和appsecret：

比如我们想取公众号的组数据：
if (isset($argc)  && $argc >= 1 && $argv[0] == __FILE__) {
    $client = new WechatJSON(array(
        WechatJSON::APP_ID => 'wx78acfe8257asDb1',
        WechatJSON::APP_SECRET => '9ba3476db1ff75654aBceae0b20fb9',
    ));
    $res = $client->call('/groups/get');
    if (!$res) {
        var_dump($client->_error);
    }
    var_dump($res);
}

如下图所示：

又或者我们生成菜单：

if (isset($argc)  && $argc >= 1 && $argv[0] == __FILE__) {
    $client = new WechatJSON(array(
        WechatJSON::APP_ID => 'wx78acfe8257asDb1',
        WechatJSON::APP_SECRET => '9ba3476db1ff75654aBceae0b20fb9',
    ));
    $res = $client->call('/menu/create', array(
        'button' => array(
            array(
                'type' => 'click',
                'name' => '测试铵钮',
                'key' => 'test_btn'
            ),array(
                'type' => 'view',
                'name' => '测试跳转',
                'url' => 'http://www.baidu.com'
            ))
        ),WechatJSON::JSON);
    if (!$res) {
        var_dump($client->_error);
    }
    var_dump($res);
}

成功后返回OK如下图：

其他接口可以大家可以自己自由获取或者提交POST GET等这里不熬述了！有问题留言
