PHP采集利器:Snoopy 试用心得
?
$url = "http://www.taoav.com"; include("snoopy.php"); $snoopy = new Snoopy; $snoopy->fetch($url); //获取所有内容 echo $snoopy->results; //显示结果 $snoopy->fetchtext //获取文本内容(去掉html代码) $snoopy->fetchlinks //获取链接 $snoopy->fetchform //获取表单2 表单提交
$formvars["username"] = "admin"; $formvars["pwd"] = "admin"; $action = "http://www.taoav.com";//表单提交地址 $snoopy->submit($action,$formvars);//$formvars为提交的数组 echo $snoopy->results; //获取表单提交后的 返回的结果 $snoopy->submittext; //提交后只返回 去除html的 文本 $snoopy->submitlinks;//提交后只返回 链接?既然已经提交的表单 那就可以做很多事情 接下来我们来伪装ip,伪装浏览器
$formvars["username"] = "admin"; $formvars["pwd"] = "admin"; $action = "http://www.taoav.com"; include "snoopy.php"; $snoopy = new Snoopy; $snoopy->cookies["PHPSESSID"] = 'fc106b1918bd522cc863f36890e6fff7'; //伪装sessionid $snoopy->agent = "(compatible; MSIE 4.01; MSN 2.5; AOL 4.0; Windows 98)"; //伪装浏览器 $snoopy->referer = "http://www.only4.cn"; //伪装来源页地址 http_referer $snoopy->rawheaders["Pragma"] = "no-cache"; //cache 的http头信息 $snoopy->rawheaders["X_FORWARDED_FOR"] = "127.0.0.101"; //伪装ip $snoopy->submit($action,$formvars); echo $snoopy->results;?

原来我们可以伪装session 伪装浏览器 ,伪装ip, haha 可以做很多事情了。
$snoopy->proxy_host = "www.only4.cn"; $snoopy->proxy_port = "8080"; //使用代理 $snoopy->maxredirs = 2; //重定向次数 $snoopy->expandlinks = true; //是否补全链接 在采集的时候经常用到 // 例如链接为 /images/taoav.gif 可改为它的全链接 http://www.taoav.com/images/taoav.gif,这个地方其实可以在最后输出的时候用ereg_replace函数自己替换 $snoopy->maxframes = 5 //允许的最大框架数 //注意抓取框架的时候 $snoopy->results 返回的是一个数组 $snoopy->error //返回报错信息?上面的基本用法了解了,下面我就实例演示一次:
//echo var_dump($_SERVER); include("Snoopy.class.php"); $snoopy = new Snoopy; $snoopy->agent = "Mozilla/5.0 (Windows; U; Windows NT 5.1; zh-CN; rv:1.9.0.5) Gecko/2008120122 Firefox/3.0.5 FirePHP/0.2.1";//这项是浏览器信息,前面你用什么浏览器查看cookie,就用那个浏览器的信息(ps:$_SERVER可以查看到浏览器的信息) $snoopy->referer = "http://bbs.phpchina.com/index.php"; $snoopy->expandlinks = true; $snoopy->rawheaders["COOKIE"]="__utmz=17229162.1227682761.29.7.utmccn=(referral)|utmcsr=phpchina.com|utmcct=/html/index.html|utmcmd=referral; cdbphpchina_smile=1D2D0D1; cdbphpchina_cookietime=2592000; __utma=233700831.1562900865.1227113506.1229613449.1231233266.16; __utmz=233700831.1231233266.16.8.utmccn=(referral)|utmcsr=localhost:8080|utmcct=/test3.php|utmcmd=referral; __utma=17229162.1877703507.1227113568.1231228465.1231233160.58; uchome_loginuser=sinopf; xscdb_cookietime=2592000; __utmc=17229162; __utmb=17229162; cdbphpchina_sid=EX5w1V; __utmc=233700831; cdbphpchina_visitedfid=17; cdbphpchinaO766uPYGK6OWZaYlvHSuzJIP22VpwEMGnPQAuWCFL9Fd6CHp2e%2FKw0x4bKz0N9lGk; xscdb_auth=8106rAyhKpQL49eMs%2FyhLBf3C6ClZ%2B2idSk4bExJwbQr%2BHSZrVKgqPOttHVr%2B6KLPg3DtWpTMUI4ttqNNVpukUj6ElM; cdbphpchina_onlineusernum=3721"; $snoopy->fetch("http://bbs.phpchina.com/forum-17-1.html"); $n=ereg_replace("href=\"","href=\"http://bbs.phpchina.com/",$snoopy->results ); echo ereg_replace("src=\"","src=\"http://bbs.phpchina.com/",$n); ?>?这是模拟登陆PHPCHINA论坛的过程,首先要查看自己浏览器的信
$_SERVER['HTTP_USER_AGENT']后边的内容复制下来,粘在$snoopy->agent的地方,然后就是要查看自己的
COOKIE了,用自己在论坛的账号登陆论坛后,在浏览器地址栏里输入
javascript:document.write(document.cookie),回车,就可以看到自己的cookie信息,复制粘贴
到$snoopy->rawheaders["COOKIE"]=的后边。(我的cookie信息为了安全起见已经删除了一段内容)

PHP is widely used in e-commerce, content management systems and API development. 1) E-commerce: used for shopping cart function and payment processing. 2) Content management system: used for dynamic content generation and user management. 3) API development: used for RESTful API development and API security. Through performance optimization and best practices, the efficiency and maintainability of PHP applications are improved.

PHP makes it easy to create interactive web content. 1) Dynamically generate content by embedding HTML and display it in real time based on user input or database data. 2) Process form submission and generate dynamic output to ensure that htmlspecialchars is used to prevent XSS. 3) Use MySQL to create a user registration system, and use password_hash and preprocessing statements to enhance security. Mastering these techniques will improve the efficiency of web development.

PHP and Python each have their own advantages, and choose according to project requirements. 1.PHP is suitable for web development, especially for rapid development and maintenance of websites. 2. Python is suitable for data science, machine learning and artificial intelligence, with concise syntax and suitable for beginners.

PHP is still dynamic and still occupies an important position in the field of modern programming. 1) PHP's simplicity and powerful community support make it widely used in web development; 2) Its flexibility and stability make it outstanding in handling web forms, database operations and file processing; 3) PHP is constantly evolving and optimizing, suitable for beginners and experienced developers.

PHP remains important in modern web development, especially in content management and e-commerce platforms. 1) PHP has a rich ecosystem and strong framework support, such as Laravel and Symfony. 2) Performance optimization can be achieved through OPcache and Nginx. 3) PHP8.0 introduces JIT compiler to improve performance. 4) Cloud-native applications are deployed through Docker and Kubernetes to improve flexibility and scalability.

PHP is suitable for web development, especially in rapid development and processing dynamic content, but is not good at data science and enterprise-level applications. Compared with Python, PHP has more advantages in web development, but is not as good as Python in the field of data science; compared with Java, PHP performs worse in enterprise-level applications, but is more flexible in web development; compared with JavaScript, PHP is more concise in back-end development, but is not as good as JavaScript in front-end development.

PHP and Python each have their own advantages and are suitable for different scenarios. 1.PHP is suitable for web development and provides built-in web servers and rich function libraries. 2. Python is suitable for data science and machine learning, with concise syntax and a powerful standard library. When choosing, it should be decided based on project requirements.

PHP is a scripting language widely used on the server side, especially suitable for web development. 1.PHP can embed HTML, process HTTP requests and responses, and supports a variety of databases. 2.PHP is used to generate dynamic web content, process form data, access databases, etc., with strong community support and open source resources. 3. PHP is an interpreted language, and the execution process includes lexical analysis, grammatical analysis, compilation and execution. 4.PHP can be combined with MySQL for advanced applications such as user registration systems. 5. When debugging PHP, you can use functions such as error_reporting() and var_dump(). 6. Optimize PHP code to use caching mechanisms, optimize database queries and use built-in functions. 7
