完全禁用Guzzle的重定向

Question

Guzzle6 has one pretty option: allow_redirects . If setting this option to false value, Guzzle blocking redirect if response code like 302 or Headers has Location param.

But there is one problem. If redirect sends by client – Guzzle doesn't notice this. For example:

We have some URL http://example.com/ that redirected to page http://redirected.com/ . Send request with help Guzzle:

$oClient->request('POST', 'http://redirected.com/', [
    'form_params' => $aFormData,
    'cookies' => (new CookieJar($aPrepareCookie)),
    'debug' => true,
    'allow_redirects' => false
]);

Suppose that redirect.com has index.php like this:

<?php
    header('Location: http://www.example.com/');
?>

In this case, the redirection will be blocked from Guzzle.

Now, let's see this redirect example:

<?php
    echo '<script>window.location = "http://www.example.com/";</script>';
?>

Here we have a problem because this is client side redirect and his can't affect the Headers , Therefore Guzzle can't track HTTP Status Code or Location value.

So, how i can solve this problem and find solution?

Thanks for help!

Answer 1

As previous posters have said, Guzzle will not execute the javascript.

Your problem could easily be solved by utilizing Guzzle Middleware .

Within the middleware:

• receive the response
• parse the body for window.location="someurl"
• perform a request of "someurl"
• modify the header of the response from "someurl" to include the fact that it was a redirection.
• return the response.
