使用QueryList3.0的時候的時候報錯了 The received content is empty!

這個報錯內容其實是沒有收到正確的URL，只需要稍微修改一下即可

1.開啟 QueryList.php 大約在 285 行 找到  private function _request($url) 這個方法。

2.修改程式碼： 其實就是在curl訪問完之後如果返回的result為false 則用 get方法請求資料

//修改前--------------------------------   
 /**
     * URL請求
     * @param $url
     * @return string
     
 
*/
    private function _request($url)
    {
        echo "<pre>";
        if(function_exists('curl_init')){
   
            $ch = curl_init();
            curl_setopt($ch, CURLOPT_URL, $url);
            curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
            curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, false
 
);
            curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true);
            curl_setopt($ch, CURLOPT_AUTOREFERER, true);
            curl_setopt($ch, CURLOPT_REFERER, $url);

$result = curl_exec($ch);
            curl_close($ch);
        }elseif(version_compare(PHP_VERSION, '5.0.0')>=0){
            var_dump(2);
            $opts = array(
                'http' => array(
                    'header' => "Referer:{$url}"
                )
            );
            $result = file_get_contents($url,false,stream_context_create($opts));
        }else{
            
            $result = file_get_contents($url);
        }
        return $result;
    }
//修改後
    /**

    private function _request($url)
    {
        echo "<pre>";
        if(function_exists('curl_init')){
   
            $ch = curl_init();
            curl_setopt($ch, CURLOPT_URL, $url);
            curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);

            $result = curl_exec($ch);
            if(!$result){$result = file_get_contents($url);}
            curl_close($ch);
        }elseif(version_compare(PHP_VERSION, '5.0.0')>=0){
            var_dump(2);
            $opts = array(
                'http' => array(
                    'header' => "Referer:{$url}"
                )
            );
            $result = file_get_contents($url,false,stream_context_create($opts));
        }else{
            
            $result = file_get_contents($url);
        }
        return $result;
    }

3.修改完畢之後上傳更新程式碼，直接執行搞定!
