只为了证明PHP是最好的语言
<?php/×只为了证明PHP是最好的语言。目前设计的该程序是顺序执行,生产和消费者没有分开,使用来一个死循环,不断从redis的list里取出最新的QQ号码,然后用该QQ号码拼接出需要网站的地址,一次访问并存入mongodb,这里只是整个实现的流程代码,没有写QQ空间API接口。由于我分析的接口返回的是json,所以我直接存入mongodb。回来分析也非常方便。为了加大速度,我目前开了10进程,虽然没有到腾讯封IP的极限,但是以及到来我的笔记本的极限了。10个进程24小时可以采集180W,如果电脑配置高点,一天200多万不是问题。其中,懒得自己写curl类,用之前大神爬取知乎的时候写的类https://github.com/hhqcontinue/zhihuSpider××/include "phpspider/config.php";include "phpspider/cache.php";include "phpspider/rolling_curl.php";$cookie = trim(file_get_contents("cookie.txt"));$curl = new rolling_curl();$curl->set_cookie($cookie);$curl->set_gzip(true);$curl->callback = function($response, $info, $request, $error) { preg_match("#xxxxx#", $request['url'], $out); $qq = $out[1]; if (empty($response)) { file_put_contents("./data/error_timeout.log", date("Y-m-d H:i:s") . ' ' . $username.' --- '.json_encode($error)."\n", FILE_APPEND); // 注意这里不要用 exit,否则整个程序就断开了 return; } // 如果是个人信息 if (strpos($request['url'], 'a') ==true ) { //将信息添加至mongodb,先判断是否是错误信息 } //如果是来访QQ if (strpos($request['url'], 'b') == true) { //将信息添加至mongodb,先判断是否是错误信息 //从中取出QQ号码存入redis cache->get_instance()->lpush("qq");//一定要从左端插入,否则是出现死循环,例如A访问来B空间,B同样也访问来A空间,如果在设置网址的时候取先存入的QQ,程序就会不断在A和B之间访问,如果设置网址的时候取最新的则会将他们存入栈底部 } //如果是说说 if (strpos($request['url'], 'c') == true) { ///将信息添加至mongodb,先判断是否是错误信息 } };while(true){ $qq=cache->get_instance()->lpop("qq");//用从左端删除 if ($qq=="")$qq="12345678";//这里是登录的QQ号码 $url = "http://a".$qq;//个人信息 $curl->get($url); $url = "http://b".$qq;//来访QQ $curl->get($url); $url = "http://c".$qq;//最近说说 $curl->get($url); $data = $curl->execute(); // 睡眠100毫秒,太快了会被认为是ddos usleep(100000);}
因为,生产者和消费者没有分开,所以其中有一个问题,就是生产者产生的QQ号码多,消费者使用速度低,所以建议将采集QQ来访者和采集数据分开,采集数据可以多开写进程

JWT is an open standard based on JSON, used to securely transmit information between parties, mainly for identity authentication and information exchange. 1. JWT consists of three parts: Header, Payload and Signature. 2. The working principle of JWT includes three steps: generating JWT, verifying JWT and parsing Payload. 3. When using JWT for authentication in PHP, JWT can be generated and verified, and user role and permission information can be included in advanced usage. 4. Common errors include signature verification failure, token expiration, and payload oversized. Debugging skills include using debugging tools and logging. 5. Performance optimization and best practices include using appropriate signature algorithms, setting validity periods reasonably,

The application of SOLID principle in PHP development includes: 1. Single responsibility principle (SRP): Each class is responsible for only one function. 2. Open and close principle (OCP): Changes are achieved through extension rather than modification. 3. Lisch's Substitution Principle (LSP): Subclasses can replace base classes without affecting program accuracy. 4. Interface isolation principle (ISP): Use fine-grained interfaces to avoid dependencies and unused methods. 5. Dependency inversion principle (DIP): High and low-level modules rely on abstraction and are implemented through dependency injection.
