PHP无法从URL获取文本(file_get_content, CURL不起作用)

Question

我试图从以下url获取文本。http://stp.stheadline.com/data/indexNewsMarquee.json

我试过几种方法，但都不起作用。我现在真的走投无路了，请帮帮我，提前谢谢你。

注:我已经在我的ini.php中启用了allow_url_fopen。P.S.我使用XAMPP v3.3.2和PHP v5.6.23

以下是我尝试过的代码(都失败了)

旋度

$ch = curl_init();
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_URL, $url);
$result = curl_exec($ch);
curl_close($ch);
echo $result;

result: 空字符串

<标题> file_get_contents h1> esult: failed to open stream: HTTP请求失败!<标题> readfile h1> esult: 输出地址本身

Answer 1

你好，你必须在你的curl请求中传递header，以便服务器可以将其视为浏览器请求。

 $url="http://stp.stheadline.com/data/indexNewsMarquee.json";
 $requestHeaders = array(
    "Accept:application/json, text/javascript, */*; q=0.01",
    "Accept-Language:en-US,en;q=0.8",
    "Connection:keep-alive",
    "Host:stp.stheadline.com",
    "Origin:http://stp.stheadline.com",
    "Referer:http://stp.stheadline.com/data/indexNewsMarquee.json",
    "User-Agent:Mozilla/5.0 (Windows NT 6.1) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/49.0.2623.87 Safari/537.36"
 );
 $ch = curl_init();
 curl_setopt($ch, CURLOPT_URL, $url);
 curl_setopt($ch, CURLOPT_HTTPHEADER, $requestHeaders);
 curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
 $output = curl_exec($ch);
 curl_close($ch);
 echo $output;

Answer 2

它们要求在请求中存在一个用户代理，所以尝试:

$url='http://stp.stheadline.com/data/indexNewsMarquee.json';
$ch = curl_init();
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_USERAGENT, 'banana');
curl_setopt($ch, CURLOPT_URL, $url);
$result = curl_exec($ch);
curl_close($ch);
echo $result;

Answer 3

使用如下:

 $curl_handle=curl_init();
 curl_setopt($curl_handle,CURLOPT_URL,'Your URL');
 curl_setopt($curl_handle, CURLOPT_CONNECTTIMEOUT, 2);
 curl_setopt($curl_handle, CURLOPT_RETURNTRANSFER, 1);
 curl_setopt($curl_handle, CURLOPT_USERAGENT, 'Your application name');
$query = curl_exec($curl_handle);
curl_close($curl_handle);
print_r($query);

我从你的URL检查了这个代码。

请尝试下面的代码。

header('Content-Type: text/html; charset=utf-8');
$url='http://stp.stheadline.com/data/indexNewsMarquee.json';
$ch = curl_init();
curl_setopt($ch, CURLOPT_HTTPHEADER, array('text/html; charset=utf-8'));
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_ENCODING, "");
curl_setopt($ch, CURLOPT_URL, $url);
$result = curl_exec($ch);
curl_close($ch);
$final_result = json_decode($result);
echo "<pre>";
print_r($final_result);

我在你的代码中添加了header('Content-Type: text/html; charset=utf-8');和curl_setopt($ch, CURLOPT_ENCODING, "");，它会工作得很好，也会显示正确的字符。

试试这个。

$ch = curl_init();
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_URL, 'http://stp.stheadline.com/data/indexNewsMarquee.json');
$result = curl_exec($ch);
curl_close($ch);
echo($result); // Json data
/*$obj = json_decode($result); // To get result in array
print_r($obj);*/

或

$url = 'http://stp.stheadline.com/data/indexNewsMarquee.json';
$ch = curl_init();
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_URL, $url);
$result = curl_exec($ch);
curl_close($ch);
echo($result); // Json data

这对我来说是有效的
