PHP 无法从 URL 获取文本（file_get_content，CURL 无效）

Question

我正在尝试从以下 url 中获取文本。 http://stp.stheadline.com/data/indexNewsMarquee.json

我尝试了几种方法，但其中 none 行得通。我现在真的很绝望，请帮助我并提前致谢。

P.S。我已经在 ini.php 中启用了 allow_url_fopen。 P.S。我正在使用 XAMPP v3.3.2 和 PHP v5.6.23

以下是我尝试过（但失败）的代码

CURL

$ch = curl_init();
curl_setopt($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;

结果：空字符串

file_get_contents

echo file_get_contents($url, true);

结果：无法打开流：HTTP 请求失败！

读取文件

echo readfile($url)

结果：输出地址本身

Answer 1

他们要求用户代理出现在请求中，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 2

使用就像这样：

 $curl_handle=curl_init();
 curl_setopt($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);

我从您的 URL 那里查看了这段代码。

您好，您必须在 curl 请求中传递 header，这样服务器才能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;

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

它对我有用:)

凯文，

请尝试以下代码。

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, "");，它会很好地工作，也会显示正确的字符。
