Ken*_*nny 2 ssl curl web-scraping symfony goutte
因此,我尝试使用 Goutte 登录https网站,但出现以下错误:
cURL error 60: SSL certificate problem: unable to get local issuer certificate
500 Internal Server Error - RequestException
1 linked Exception: RingException
这是 Goutte 的创建者说要使用的代码:
use Goutte\Client;
$client = new Client();
$crawler = $client->request('GET', 'http://github.com/');
$crawler = $client->click($crawler->selectLink('Sign in')->link());
$form = $crawler->selectButton('Sign in')->form();
$crawler = $client->submit($form, array('login' => 'fabpot', 'password' => 'xxxxxx'));
$crawler->filter('.flash-error')->each(function ($node) {
print $node->text()."\n";
});

或者这里是 Symfony 推荐的代码:
use Goutte\Client;
// make a real request to an external site
$client = new Client();
$crawler = $client->request('GET', 'https://github.com/login');
// select the form and fill in some values
$form = $crawler->selectButton('Log in')->form();
$form['login'] = 'symfonyfan';
$form['password'] = 'anypass';
// submit that form
$crawler = $client->submit($form);

问题是它们都不起作用,我收到了上面发布的错误。我CAN,但在登录使用写在过去的这个问题,我问过的代码:卷曲刮然后解析/查找具体内容
我只想使用 Symfony/Goutte 登录,这样抓取我需要的数据会更容易。请问有什么帮助或建议吗?谢谢!
在代码中添加以下内容可修复错误(curl 配置):
// make a real request to an external site
$client = new Client();
$client->getClient()->setDefaultOption('config/curl/'.CURLOPT_SSL_VERIFYHOST, FALSE);
$client->getClient()->setDefaultOption('config/curl/'.CURLOPT_SSL_VERIFYPEER, FALSE);
$crawler = $client->request('GET', 'https://github.com/login');

但随后发生了另一个错误:
The current node list is empty.
500 Internal Server Error - InvalidArgumentException

再一次,我将 Goutte 与 Symfony 和默认代码一起使用来执行测试任务,例如登录 https github。
上一个错误的修复方法node list empty是 Github 登录页面按钮实际上显示“登录”,而不是按钮上的提交或登录。不幸的是,Goutte api 不清楚是$form = $crawler->selectButton('Sign in')->form();指 htmlname属性还是按钮的实际纯文本。显然是纯文本;有点混乱。因此,在对文档记录不佳的 api 进行了更多研究后,我以以下有效的代码结束:
// make a real request to an external site
$client = new Client();
$client->getClient()->setDefaultOption('config/curl/'.CURLOPT_SSL_VERIFYHOST, FALSE);
$client->getClient()->setDefaultOption('config/curl/'.CURLOPT_SSL_VERIFYPEER, FALSE);
$crawler = $client->request('GET', 'https://github.com/login');
// select the form and fill in some values
$form = $crawler->selectButton('Sign in')->form();
$form['login'] = 'symfonyfan';
$form['password'] = 'anypass';
// submit that form
$crawler = $client->submit($form);
echo $crawler->html();
