Guzzle7 multipart/form-data POST 无法正常工作

Question

我正在尝试重新创建提交表单。但由于某种原因，我的 POST 请求没有返回正确的页面。下面我包含了一个可以工作的原始 CURL 请求，然后是我的 Guzzle 代码，它不起作用。

我损坏的 Guzzle 代码和正常的 CURL 请求有什么区别？

我的 Guzzle 代码：

    $jar = new \GuzzleHttp\Cookie\CookieJar;

    $client = new \GuzzleHttp\Client([
        'base_uri' => 'https://www.southeastwater.co.uk',
        'cookies' => $jar,
    ]);
    $res = $client->request('GET', '/my-water-supply/my-water-looks-smells-strange/check-your-water-quality-hardness');

    $html = new \simplehtmldom\HtmlDocument($res->getBody());
    $form = $html->find('form.sewForm',1);
    foreach($form->find('input') as $n => $input){
        $x = [
            'name' => $input->name,
            'contents' => $input->value,
        ];
        $post[] = $x;

        if($n == 0){ // This is button field does just manually add it after the first input
            $post[] = [
                'name' => 'Jump',
                'contents' => '10',
            ];
        }
    }


    $post = [
        'multipart/form-data' => $post
    ];

    $res2 = $client->post('/my-water-supply/my-water-looks-smells-strange/check-your-water-quality-hardness', $post);
    echo $res2->getBody();
    // But body is wrong, it's shows HTML as if I had just refreshed the page and not submitted the POST at all.
    exit();

这是有效的 CURL 请求：

Answer 1

首先我觉得你正在获取一个 Cookie jar 实例但没有设置 cookie。

$jar = new \GuzzleHttp\Cookie\CookieJar;
$jar = \GuzzleHttp\Cookie\CookieJar::fromArray(
    [
        '__RequestVerificationToken' => 'your token ...'
    ],
    'https://www.southeastwater.co.uk'
);
$r = $client->request('GET', 'https://www.southeastwater.co.uk', [
    'cookies' => $jar
]);

您还需要在 guzzle 的 multipart 键中将要发送的内容作为 multipart/form-data 发送。

$res2 = $client->post('/my-water-supply/my-water-looks-smells-strange/check-your-water-quality-hardness', [
    'multipart' => $post
    ]
]);
    

注意：

我假设$post 是从这一步获得的。

$post[] = [
                'name' => 'Jump',
                'contents' => '10',
            ];
