其实我不是在做屏幕爬虫，而是想爬取它的json数据.我在浏览器中打开网络"选项卡并查看 XHR 部分，然后我想从该 XHR 部分获取响应.那么怎么做，我的代码有什么问题?

Actually I'm not doing screen crawling, but I want to crawl its json data. I open the "Network" Tab in browser and see the XHR section, and then I want to grab the response from that XHR section. So how to do it and what's wrong with my code?

推荐答案

根据您使用以下代码提供的 URL，您将获得重定向链接:

As per the URL you have given using the below code, you would get nothing rather the redirection link:

用正确的api替换链接和参数:

Replace with the link and parameters with the correct api:

此处给出了使用 CURL 的一般格式:

General format of using CURL is given here:

            $ch = curl_init();

           $params = urldecode('{"ap":"' . 'JKTA.DPS' . '","dt":"' . '14-10-2017.NA' . '","ps":"' . '1.0.0'. '","sc":"' . 'ECONOMY'. '"}');



            $url = 'https://www.traveloka.com/en/flight/fullsearch?JsonData=' . $params;
            curl_setopt($ch, CURLOPT_URL, $url);
            curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
            // curl_setopt($ch, CURLOPT_USERAGENT, "Mozilla/5.0");

            curl_setopt($ch, CURLOPT_HEADER, 0);

            // Should cURL return or print out the data? (true = return, false = print)
            curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);

            // Timeout in seconds
            curl_setopt($ch, CURLOPT_TIMEOUT, 10);

            // Download the given URL, and return output
            $output = curl_exec($ch);

            // Close the cURL resource, and free system resources
            curl_close($ch);

            if (!empty($output)) {
                $x = json_decode($output, true);
                        var_dump($x);   
                   }else{
                      return FALSE;
                   }
