微信開發 token驗證失敗 200302 報錯 err_msg: "verify token fail" ret: 200302

 

微信接入事件回調的時候，用的是微信官方的代碼，但是就是無法通過驗證，實在是想罵罵騰訊寫文檔的人

我的代碼如下：

//回調鑑權
    public function check_signature()
    {
        $param = $this->request->get();
        $signature = $param["signature"];
        $timestamp = $param["timestamp"];
        $nonce = $param["nonce"];
        $token = config('wx_trade_plugin')['token'];
        $tmpArr = array($token, $timestamp, $nonce);
        sort($tmpArr, SORT_STRING);
        $tmpStr = implode($tmpArr);
        $tmpStr = sha1($tmpStr);
        $param['tmpStr'] = $tmpStr;
        if ($tmpStr == $signature ) {
            echo $param["echostr"]);
        } else {
            echo 'error';
        }
    }

思來想去還是覺得沒毛病，於是我自己用postman測試，也看不出任何問題

終於在試了很多次之後，我將代碼改成這樣子，神奇的通過了，心中萬馬奔騰！！！

//回調鑑權
    public function check_signature()
    {
        $param = $this->request->get();
        $signature = $param["signature"];
        $timestamp = $param["timestamp"];
        $nonce = $param["nonce"];
        $token = config('wx_trade_plugin')['token'];
        $tmpArr = array($token, $timestamp, $nonce);
        sort($tmpArr, SORT_STRING);
        $tmpStr = implode($tmpArr);
        $tmpStr = sha1($tmpStr);
        $param['tmpStr'] = $tmpStr;
        //重點
        header("Content-type: text/html; charset=utf-8");
        if ($tmpStr == $signature ) {
        	//重點
            echo htmlspecialchars($param["echostr"]);
        } else {
            echo 'error';
        }
    }
