带有POST数据的cURL错误 [英] Error on cURL with POST data

问题描述

我想使用Php Curl从此URL提取数据：

I want to extract data from this URL with Php Curl:

https://www.traveloka.com/zh_CN/flight/ fullsearch？ap = JKTA.DPS& dt = 14-10-2017.NA& ps = 1.0.0& sc = Economy

但是我收到以下错误：

{ errorType： SERVER_ERROR， userErrorMessage：发生意外的服务器错误。我们对不便表示抱歉。请稍后再试。， errorMessage：服务器中发生异常。}。

"{"errorType":"SERVER_ERROR","userErrorMessage":"Unexpected server error occurred. We apologize for the inconvenience. Please try again later.","errorMessage":"Exception occurred in server."}".

如何提取数据

这是我的代码

$ch = curl_init($url);

$result = curl_exec($ch);

print_r($result);

curl_close($ch);    

实际上我不是在进行屏幕爬网，但是我想对它的json数据进行爬网。我在浏览器中打开网络选项卡，然后看到 XHR部分，然后我想从该 XHR部分中获取响应。那么如何做以及我的代码有什么问题呢？

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，您重定向链接不会得到任何帮助：

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

使用正确的api替换链接和参数：

Replace with the link and parameters with the correct api:

常规使用CURL的格式如下：

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;
                   }
