使用CURL发送自定义标头

Question

我想通过API向Web服务发送请求,如下所示,我必须传递自定义http标头(Hash),我使用CURL,我的代码似乎工作但我没有得到严格的响应,我被告知它与哈希值有关,虽然值被认为是正确的,我传递它或代码本身的方式有什么不对.

 <?php
    $ttime=time();
    $hash="123"."$ttime"."dfryhmn";
    $hash=hash("sha512","$hash");
    $curl = curl_init();
    curl_setopt($curl,CURLOPT_HTTPHEADER,array('Hash:$hash'));      
    curl_setopt ($curl, CURLOPT_URL, 'http://web-service-api.com/getresult.xml?clientid=456&time=$ttime');  
    curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1);  
    $xml = curl_exec ($curl);  

    if ($xml === false) {
        die('Error fetching data: ' . curl_error($curl));  
    }
    curl_close ($xml);  

    echo htmlspecialchars("$xml", ENT_QUOTES);

    ?>

如果您需要在php中获取并设置自定义http标头,以下简短教程非常有用:

发送请求标头

$uri = 'http://localhost/http.php';
$ch = curl_init($uri);
curl_setopt_array($ch, array(
    CURLOPT_HTTPHEADER  => array('X-User: admin', 'X-Authorization: 123456'),
    CURLOPT_RETURNTRANSFER  =>true,
    CURLOPT_VERBOSE     => 1
));
$out = curl_exec($ch);
curl_close($ch);
// echo response output
echo $out;

阅读自定义标题

print_r(apache_request_headers());

你应该看到

Array
(
    [Host] => localhost
    [Accept] => */*
    [X-User] => admin
    [X-Authorization] => 123456
    [Content-Length] => 9
    [Content-Type] => application/x-www-form-urlencoded
)

使用PHP CGI自定义标头

在.htaccess

RewriteEngine On
RewriteRule .? - [E=User:%{HTTP:X-User}, E=Authorization:%{HTTP:X-Authorization}]

从$ _SERVER中读取自定义标头

echo $_SERVER['User'];    
echo $_SERVER['Authorization'];

'Hash:$hash'应该是"Hash: $hash"(双引号)或'Hash: '.$hash

传入的URL也是如此 CURLOPT_URL
