当我通过Chrome浏览器调试网站时,我获得了JSON响应。但是当我尝试通过PHP执行此操作时,我收到错误消息。
无法打开流:HTTP请求失败!找不到HTTP / 1.0 404
感谢您的帮助。
例如:
Chrome中可以做的事情:
转到页面:http://gruper.pl/warszawa,在底部你会看到一个按钮“Wiecej ofert”。点击后,您将在调试中看到:
http://gruper.pl/DataProvider.php?cityId=51&categoryId=0&mainNaviId=1&showBTile=true&page=1
并回复:
[{"ID_PAGE":"59199","ID_CITY":"3952","main_city":"3952","date_start":"2014-02-23 18:00:00","date_end":"2014-03-01 23:59:00","price".....
是否有可能在PHP中获得相同的内容?
我的代码是:
<?php
$url = 'http://gruper.pl/DataProvider.php?cityId=51&categoryId=0&mainNaviId=1&showBTile=true&page=1';
// use key 'http' even if you send the request to https://...
$options = array(
'http' => array(
'header' => "Content-type: application/x-www-form-urlencoded\r\n" .
"Accept:application/json\r\n" .
"Accept-Encoding:gzip,deflate,sdch\r\n" .
"X-Requested-With:XMLHttpRequest\r\n",
'method' => 'GET'
),
);
$context = stream_context_create($options);
$result = (file_get_contents($url, false, $context));
?>
<html>
<head>
<meta charset="UTF-8">
</head>
</html>
答案 0 :(得分:1)
看起来该URL将返回404 HTTP状态代码,除非设置了这些标头:
X-Requested-With: XMLHttpRequest
Referer: http://gruper.pl/warszawa
所以这会奏效:
<?php
$url = 'http://gruper.pl/DataProvider.php?cityId=51&categoryId=0&mainNaviId=1&showBTile=true&page=1';
// use key 'http' even if you send the request to https://...
$options = array(
'http' => array(
'header' => "X-Requested-With: XMLHttpRequest\r\n" .
"Referer: http://gruper.pl/warszawa"
)
);
$context = stream_context_create($options);
$result = (file_get_contents($url, false, $context));
echo $result;
?>
