Question

我正在使用 simpleTest WebBrowser 在此 URL http://www.magicbricks.com/bricks/agentSearch 上进行数据抓取.html。但是，尽管一切看起来都正确，但我总是收到错误City Field is required。我想问题可能在于，当 State 值发生变化时，city 字段中的值会动态变化。有什么解决办法吗？这是我的代码。

<?php
require_once('simpletest/browser.php');

$browser = &new SimpleBrowser();
$browser->addHeader('User-Agent: Mozilla/5.0 (Windows NT 6.1; WOW64; rv:6.0.2) Gecko/20100101 Firefox/6.0.2');
$browser->get('http://www.magicbricks.com/bricks/agentSearch.html');
$browser->setField('source','agentSearch');
$browser->setField('_transactionType','1');
$browser->setField('_propertyType','1');
$browser->setField('resultPerPage','50');
$browser->setField('agentSearchType','B');
$browser->setField('state','520');
$browser->setField('city','4320');
$browser->setField('keyword','');
$browser->setField('country','50');

print $browser->submitFormById('searchFormBean');
print $browser->getResponseCode()

?>

Answer 1

以下是我注意到的一些错误 字段

丢失

1. 缺少agentSearchType字段
2. 缺少transactionType（有transactionType和_transactionType）
3. 缺少propertyType（有propertyType和_propertyType）

您需要添加一些标头信息，例如

1. Referer
2. Cookie

典型的后期测试如果您查看标题，应该采用这种格式

        POST http://www.magicbricks.com/bricks/agentSearch.html HTTP/1.1

我希望这有帮助
