微信公众号开发实践

1、验证服务器消息

public function index(Request $request)
{
    $signature = $request->get('signature');
    $timestamp = $request->get('timestamp');
    $nonce = $request->get('nonce');

    $validate = new ValidateMsg();//初始化该验证类，调用验证方法即可

    if ($validate->validateToken($signature, $timestamp, $nonce, $token)) {
        return $request->get('echostr');
    } else {
        return '';
    }
}

2、消息处理

//初始化消息处理类：处理消息接收和解密操作（如果有密文）
$params = [
            'token' => config('wechatC.token'),
            'encodingAesKey' => config('wechatC.encodeKey'),
            'appid' => config('wechatC.appid'),
            'timestamp' => $request->input('timestamp',''),
            'nonce' => $request->input('nonce',''),
            'msgSignatur' => $request->input('msg_signature',''),
            'encryptType' => $request->input('encrypt_type',''),
        ];
$msgManage = new MessageManage($params);

//获取推送的原始消息体，如果是密文的话就是密文格式
$receipt = $msgManage->getSourceMessage() 

//获取明文消息，数组格式数据
$message = $msgManage->getMessage();

//格式化成文本消息格式'<Content><![CDATA[' . $data['content'] . ']]></Content>'
//$data内容根据实际消息类型而定
//文本['content']; link:[title,description,url];image:[media_id]
//vioce:[media_id]; video:[title,description,media_id]
//news: [[title,description,url,picurl]]
$content = $msgManage->textContent($data)

//格式化成微信服务器可识别的xml数据，如果推送的消息是加密的话，将返回加密密文格式
$response = $msg->convertResponseMessage($message, $MsgType, $contents)

3、加密解密

//使用openssl_encrypt()进行加密，因为php7.1废弃了mcrypt加密
//解密openssl_decrypt()解密
//具体参见PrpCrypt.php文件
