PHP GUZLE HTTP获取响应位置头

PHP GUZLE HTTP获取响应位置头,php,curl,guzzle,guzzle6,guzzlehttp,Php,Curl,Guzzle,Guzzle6,Guzzlehttp,我用GuzzleHttp 6发出了一个GET请求: use GuzzleHttp\Client as GuzzleClient; $client = new GuzzleClient([ 'headers' => [ 'Authorization'=>'Bearer XXXX' ], ]); $downloadUrl = "XXX"; $response = $client->request('GET', $downloadUrl); $hea

我用GuzzleHttp 6发出了一个
GET
请求:

use GuzzleHttp\Client as GuzzleClient;
$client = new GuzzleClient([
  'headers' => [
    'Authorization'=>'Bearer XXXX'
  ],        
]);
$downloadUrl = "XXX";
$response = $client->request('GET', $downloadUrl);

$headers = $response->getHeaders();
var_dump($headers['Location']);
var_dump($response->getHeader('Location'));
这些变量转储打印空数组,如
位置
标头不存在

当我用curl从终端发出请求时,我收到了以下响应:

< HTTP/1.1 302 Found
< Cache-Control: private
< Transfer-Encoding: chunked
< Content-Type: text/plain
< Location: https://xxxx.xxx/yyy/zzz

通过设置
track\u redirects
on\u redirect
callback,不会发生任何情况:

$onRedirect = function(RequestInterface $request, ResponseInterface $response, UriInterface $uri){
    echo 'Redirecting! ' . $request->getUri() . ' to ' . $uri . "\n";
};

$response = $client->request('GET', $downloadUrl, [
    'allow_redirects' => [
        'max'             => 10,        // allow at most 10 redirects.
        'strict'          => true,      // use "strict" RFC compliant redirects.
        'referer'         => true,      // add a Referer header
        'protocols'       => ['http', 'https'], // only allow https URLs
        'on_redirect'     => $onRedirect,
        'track_redirects' => true
    ]
]);

var_dump($response->getHeaderLine('X-Guzzle-Redirect-Status-History'));
var_dump($response->getHeaderLine('X-Guzzle-Redirect-History'));
var_dump($response->getHeaderLine('Location'));
打印出:

string(0) ""
string(0) ""
string(0) ""

您应该将Guzzle handler更改为Curl

首先,您应该确保系统中安装了
php curl

如果没有安装
php curl
,请在安装后检查是否仍然没有收到
位置
标题

如果问题仍然存在,您可以尝试:

use GuzzleHttp\HandlerStack;
use GuzzleHttp\Handler\CurlHandler;

$handler = new CurlHandler();
$stack = HandlerStack::create($handler); // Wrap w/ middleware

$client = new GuzzleClient([
    'headers' => $headers,
    'handler'=> $stack
]);

“就像位置标头不存在一样”-这是因为它不存在。默认情况下,Guzzle会自动跟踪重定向,您查看的标题是导致重定向的后续请求的标题,而不是原始标题。我使用HTTP 6,我尝试禁用重定向,或者在发生重定向而未执行回调时执行回调,然后尝试设置
track\u重定向
,然后检查标题
X-Guzzle-Redirect-History
X-Guzzle-Redirect-Status-History
的内容。@misorude我更新了问题。。。还是没有你检查过实际的反应是什么吗?也许您通过Guzzle发出的请求得到的响应与您使用cURL发出请求时看到的不同(由于某些重要的请求特征在某种程度上有所不同),因此可能只是您正在寻找一开始没有发生的重定向…?
use GuzzleHttp\HandlerStack;
use GuzzleHttp\Handler\CurlHandler;

$handler = new CurlHandler();
$stack = HandlerStack::create($handler); // Wrap w/ middleware

$client = new GuzzleClient([
    'headers' => $headers,
    'handler'=> $stack
]);
