QueryList post($url,$args = null,$otherArgs = [])

Http post插件,用于post表单。默认已经开启了与get()方法共享cookie 。

postJson()方法用法同post()方法.

用法

用法同http get插件

  1. $ql->post('http://httpbin.org/post',[
  2.     'param1' => 'testvalue',
  3.     'params2' => 'somevalue'
  4. ],[
  5.     'proxy' => 'http://222.141.11.17:8118',
  6.     'timeout' => 30,
  7.     'headers' => [
  8.         'Referer' => 'https://querylist.cc/',
  9.         'User-Agent' => 'testing/1.0',
  10.         'Accept'     => 'application/json',
  11.         'X-Foo'      => ['Bar', 'Baz'],
  12.         'Cookie'    => 'abc=111;xxx=222'
  13.     ]
  14. ]);
  15. echo $ql->getHtml();

输出:

  1. {
  2.   "args": {},
  3.   "data": "",
  4.   "files": {},
  5.   "form": {
  6.     "param1": "testvalue",
  7.     "params2": "somevalue"
  8.   },
  9.   "headers": {
  10.     "Accept": "application/json",
  11.     "Connection": "close",
  12.     "Content-Length": "34",
  13.     "Content-Type": "application/x-www-form-urlencoded",
  14.     "Cookie": "abc=111;xxx=222",
  15.     "Host": "httpbin.org",
  16.     "Proxy-Connection": "Keep-Alive",
  17.     "Referer": "https://querylist.cc/",
  18.     "User-Agent": "testing/1.0",
  19.     "X-Foo": "Baz"
  20.   },
  21.   "json": null,
  22.   "origin": "222.141.11.17",
  23.   "url": "http://httpbin.org/post"
  24. }

连贯操作

http插件默认已经开启了全局cookie，post操作和get操作是cookie共享的,意味着你可以先调用post方法登录，然后get方法就可以采集所有登录后的页面。

  1. $ql = QueryList::post('http://xxxx.com/login',[
  2.     'username' => 'admin',
  3.     'password' => '123456'
  4. ])->get('http://xxx.com/admin');
  6. $ql->get('http://xxx.com/admin/page');
  8. //echo $ql->getHtml();

实战：模拟登陆GitHub

  1. $ql = QueryList::getInstance();
  2. //手动设置cookie
  3. $jar = new \GuzzleHttp\Cookie\CookieJar();
  5. //获取到登录表单
  6. $form = $ql->get('https://github.com/login',[],[
  7.     'cookies' => $jar
  8. ])->find('form');
  10. //填写GitHub用户名和密码
  11. $form->find('input[name=login]')->val('your github username or email');
  12. $form->find('input[name=password]')->val('your github password');
  14. //序列化表单数据
  15. $fromData = $form->serializeArray();
  16. $postData = [];
  17. foreach ($fromData as $item) {
  18.     $postData[$item['name']] = $item['value'];
  19. }
  21. //提交登录表单
  22. $actionUrl = 'https://github.com'.$form->attr('action');
  23. $ql->post($actionUrl,$postData,[
  24.     'cookies' => $jar
  25. ]);
  27. //判断登录是否成功
  28. // echo $ql->getHtml();
  29. $userName = $ql->find('.header-nav-current-user>.css-truncate-target')->text();
  30. if($userName)
  31. {
  32.     echo '登录成功!欢迎你:'.$userName;
  33. }else{
  34.     echo '登录失败!';
  35. }

输出:

  1. 登录成功!欢迎你:jae-jae
