guzzle 使用登录表单进行身份验证

Question

是否可以使用登录表单对用户进行身份验证，例如通过 https://github.com/login 登录 GitHub，然后转到需要登录的页面，例如 https://github.com/settings/profile？我知道像 "FriendsOfPHP/Goutte" 这样的包可以完成这项工作，但他们使用带有 guzzle 的 "symfony/browser-kit" 包。是否可以只用 guzzle 来做到这一点？我试过了但是登录没有验证：

<?php

use GuzzleHttp\Client;
use GuzzleHttp\Exception\RequestException;
use GuzzleHttp\Cookie\FileCookieJar;

class guzzleRequest {

    private $client;
    private $jar;
    private $body;
    private $baseUrl;
    private $host;
    private $path;

    public function __construct($base_url, $host) {
        $this->path = __DIR__ . '/tmp/cookie.txt';
        $this->jar = new FileCookieJar($this->path);
        $this->client = new Client(['cookies' => $this->jar, 'allow_redirects' => TRUE]);
        $this->baseUrl = $base_url;
        $this->host = $host;
    }

    protected function makeRequest($page, $query = array(), $debug = false) {
        try {
            $options = [
                'headers' => [
                    'User-Agent' => 'Mozilla/5.0 (Windows NT 10.0; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/50.0.2661.102 Safari/537.36',
                    'Host' => $this->host,
                    'Referer' => $this->baseUrl . $page
                ]
            ];

            if (!empty($query)) {
                $options['query'] = $query;
            }

            $res = $this->client->request('GET', $this->baseUrl . $page, $options);
            $this->body = $res->getBody();

            return true;
        } catch (RequestException $e) {
            $this->body = $e->getResponse()->getBody();
            return false;
        }
    }

    public function getPage($page) {

        $this->makeRequest($page);
        return $this->body;
    }

    public function submitForm($page, $query = array(), $form_params = array(), $debug = false) {
        try {
            $options = [
                'headers' => [
                    'User-Agent' => 'Mozilla/5.0 (Windows NT 10.0; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/50.0.2661.102 Safari/537.36',
                    'Host' => $this->host,
                    'Referer' => $this->baseUrl . $page
                ]
            ];

            if (!empty($query)) {
                $options['query'] = $query;
            }

            if (!empty($form_params)) {
                $options['form_params'] = $form_params;
            }

            $res = $this->client->request('POST', $this->baseUrl . $page, $options);
            $this->body = $res->getBody();
            $this->jar->save($this->path);
            return true; //everything is fine
        } catch (RequestException $e) {
            $this->body = $e->getResponse()->getBody();
            return false;
        }
    }

    public function saveBody($mod = '') {
        file_put_contents('tmp/output' . $mod . '.html', $this->body);
    }

    public function loadBody() {
        $this->body = file_get_contents('test/output.html');
        return $this->body;
    }

}

然后调用它：

require_once 'vendor/autoload.php';
require_once 'guzzleRequest.php';

$guzzleRequest = new guzzleRequest("https://github.com", "github.com");
$form_params = ["login" => "user", "password" => "pass"];
$guzzleRequest->submitForm('/session', array(), $form_params, true);
$guzzleRequest->getPage('/settings/profile');
$guzzleRequest->saveBody();

但在 output.html 中，保存页面是 "github.com/login" 并且用户未通过身份验证

我在 github 中打开了一个问题，得到的答案是仅使用 guzzle 是不可能做到这一点的 “https://github.com/guzzle/guzzle/issues/1817”

guzzle 使用登录表单进行身份验证

guzzle authenticate with login form

php
