微信注册测试号url和token报错{"errcode":-106,"errmsg":"token check fail"}

先说问题:一直显示token跟代码里面的对不上,但是代码是一样的
百度的方法很多都看了用了都没用,哪位那个能帮忙看一下.
代码如下:

input('signature');
        $timestamp = $request->input('timestamp');
        $nonce = $request->input('nonce');
        $echoStr = $request->input('echostr');
        if ($this->checkSignature($signature, $timestamp, $nonce)) {
            return $echoStr;
        } else {
            return 'Token verification failed.';
        }
    }
 
    /**
     * 微信官方提供的验签方法
     *
     * @param $signature
     * @param $timestamp
     * @param $nonce
     * @return bool
     */
    private function checkSignature($signature, $timestamp, $nonce)
    {
        $token = WECHAT_VERIFY_TOKEN;
        $tmpArr = array($token, $timestamp, $nonce);
        sort($tmpArr, SORT_STRING);
        $tmpStr = implode($tmpArr);
        $tmpStr = sha1($tmpStr);
 
        if ($tmpStr == $signature) {
            return true;
        } else {
            return false;
        }
    }
 
}
