最近在做一个微信上查询四六级成绩的功能,学信网可以抓取,但是爬了1000左右后,就会出现验证码,只好放弃这个方法。有人可以从99宿舍网爬取,但他们不愿意告知,求大神告知具体方法。

最近在做一个微信上查询四六级成绩的功能,学信网可以抓取,但是爬了1000左右后,就会出现验证码,只好放弃这个方法。有人可以从99宿舍网爬取,但他们不愿意告知,求大神告知具体方法。
做了个DEMO:http://cet.zy62.com/
使用方法$rs = cet('姓名','准考证号'); var_dump($rs);
<code>function cet($name,$id){ $name = urlencode(mb_convert_encoding($name, 'gb2312', 'utf-8')); $post = 'id=' . $id . '&name=' . $name; $url = "http://cet.99sushe.com/findscore"; $ch = curl_init(); curl_setopt($ch, CURLOPT_URL, $url); curl_setopt($ch, CURLOPT_REFERER, "http://cet.99sushe.com/"); curl_setopt($ch, CURLOPT_POST, 1); curl_setopt($ch, CURLOPT_POSTFIELDS, $post); curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1); curl_setopt($ch, CURLOPT_NOBODY, false); $str = curl_exec($ch); curl_close($ch); $str = iconv("GB2312", "UTF-8", $str); if (strlen($str) </code>

遇到验证码,可能是你的爬虫没有换Ip。那就1000左右的时候更换IP继续爬就OK了。简单的验证码是可以破解的。

You should care about DependencyInjection(DI) because it makes your code clearer and easier to maintain. 1) DI makes it more modular by decoupling classes, 2) improves the convenience of testing and code flexibility, 3) Use DI containers to manage complex dependencies, but pay attention to performance impact and circular dependencies, 4) The best practice is to rely on abstract interfaces to achieve loose coupling.

Select DependencyInjection (DI) for large applications, ServiceLocator is suitable for small projects or prototypes. 1) DI improves the testability and modularity of the code through constructor injection. 2) ServiceLocator obtains services through center registration, which is convenient but may lead to an increase in code coupling.
