Alibaba商家信息采集说明

 

一、             如何获取商家列表页面链接

http://www.alibaba.com/corporations/jiangmen/CN——————————–.html

例如此页面为alibaba上所有jiamen商家信息列表,也能看到Page:1/29字样

http://www.alibaba.com/corporations/jiangmen/CN——————————–/2.html?tracelog=24581_list_turnpage

可发现末尾变成了2.html……

把?以及后面的参数去掉,并修改3、4、5试试

http://www.alibaba.com/corporations/jiangmen/CN——————————–/2.html

http://www.alibaba.com/corporations/jiangmen/CN——————————–/3.html

http://www.alibaba.com/corporations/jiangmen/CN——————————–/5.html

发现通用的列表页面链接应该是:

http://www.alibaba.com/corporations/jiangmen/CN——————————–/{$page}.html

 

二、             从列表页面获取所有页面内容

由于alibaba防采集,所以我们伪装成IE浏览器的HTTP访问。

$HTTP_SESSION=_rand();

$HTTP_SESSION;

$HTTP_URL=”http://www.alibaba.com/corporations/jiangmen/CN——————————–/”.$page.”.html”;

$ch = curl_init();

curl_setopt ($ch,CURLOPT_URL,$HTTP_URL);

curl_setopt($ch,CURLOPT_RETURNTRANSFER,true);

curl_setopt($ch,CURLOPT_USERAGENT,”Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1; SV1; .NET CLR 1.1.4322; .NET CLR 2.0.50727)”);

$res = curl_exec($ch);

curl_close ($ch);

?>

这样列表页的内容就赋值给了$res

 

三、             如何从列表页面获取具体商家链接

以第一页为例

http://www.alibaba.com/corporations/jiangmen/CN——————————–/1.html

查看源代码,可以发现所有商家名称的链接都是此样式

Jiangmen Ronda Battery Co., Ltd.

即http://{CompanyName}.en.alibaba.com

用正则从$res的内容中找出所有的{CompanyName}:

preg_match_all(‘/href\s*=\s*["|\']?([^\s"\'>]*).en.alibaba.com\”/i’,$res,$arr);

 

这样$arr中就是列表第一页中所有的商家的链接了。

 

四、             如何采集商家信息

首先循环得到单个商家的链接

foreach($arr[1] as $a=>$web)

?>

$web拼上.en.alibaba.com就是商家链接了

例如http://rondabattery.en.alibaba.com/

浏览发现 所有公司的联系信息都是http://rondabattery.en.alibaba.com/contactinfo.html

再伪装IE采集一次单个商家的联系信息页面

$HTTP_SESSION=_rand();

       $HTTP_SESSION;

       $HTTP_Server=$web;

       $HTTP_URL=”.en.alibaba.com/contactinfo.html“;

       $ch1 = curl_init();

       curl_setopt ($ch1,CURLOPT_URL,$HTTP_Server.$HTTP_URL);

       curl_setopt($ch1,CURLOPT_RETURNTRANSFER,true);

       curl_setopt($ch1,CURLOPT_USERAGENT,”Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1; SV1; .NET CLR 1.1.4322; .NET CLR 2.0.50727)”);

       $res1 = curl_exec($ch1);

       curl_close ($ch1);

?>

这样$res1中就是这个rondabattery公司联系信息页面的内容了。

 

五、             如何采集联系人、电话等详细信息

http://rondabattery.en.alibaba.com/contactinfo.html

查看源代码可以发现

       

Company Name:

       

       Jiangmen Ronda Battery Co., Ltd.

公司名等信息都是这样的格式

在用正则匹配就行了:

preg_match(“/Company Name:(.*?)/s”,$res1,$Cname);

这样$Cname中就是绿色的内容

       

Company Name:

       

       Jiangmen Ronda Battery Co., Ltd.

显然

不是我们需要的内容

$Cname = trim(strip_tags($Cname[1]));

trim:去除字符串首尾的空格,

 

tip:

有时会碰到内容中有双引号(”),常见于公司介绍等内容,需要替换掉,否则存数据库时会出现sql语句错误。

$name = str_replace(“\“,”",$name);

 

六、             将获取的信息存入数据库

mysql_pconnect(“localhost”, “root“, “password“) or

       die (“Could not connect” . mysql_error());

mysql_select_db(“company“);

mysql_query(“SET NAMES ‘UTF8′”);

 

$result = mysql_query(“

INSERT INTO alibaba (

Name,Company,Address,City,Province,Region,Zip,Tel,Phone,Fax,Web

) VALUES(

‘”.htmlspecialchars($name).”‘,

‘”.htmlspecialchars($Cname).”‘,

‘”.htmlspecialchars($Add).”‘,

‘”.htmlspecialchars($City).”‘,

‘”.htmlspecialchars($Pronvice).”‘,

‘”.htmlspecialchars($Region).”‘,

‘”.htmlspecialchars($Zip).”‘,

‘”.htmlspecialchars($Tel).”‘,

‘”.htmlspecialchars($Phone).”‘,

‘”.htmlspecialchars($Fax).”‘,

‘”.htmlspecialchars($Web).”‘

)”);

?>

Htmlspecialchars是将内容中的html字符做转义处理,但默认不处理双引号,所以前面有提到需要单独将双引号替换。

 

帐户、密码、数据库名、表名以及其中各个字段定义请根据实际情况做修改。

 

七、             如何处理每个列表页面

前面的循环只将列表页面第一页的20个商家做了采集,但是有29个列表页面需要处理。

这样做一个带参数的页面跳转。

if($page >= 29){

       echo “OVER!”;exit();

}else{

       echo “++$page.”‘>”;

}

?>

然后在此php文件的开头获取需要处理的列表页号

if($_GET['page']){

       $page = $_GET['page'];

}else{

       $page = ’1′;

}

?>

 

这样php运行时会先获取需要处理的列表页号,

如果没有传page参数则从第一页开始执行,

拼出链接,即文章最开头提到的

$HTTP_URL=”http://www.alibaba.com/corporations/jiangmen/CN——————————–/”.$page.”.html”;

 

在程序最后会判断当前处理了多少页,如果达到最大页面数就显示OVER并结束程序。

否则++$page,将页号加1并做跳转继续执行此程序。

 

八、             php代码

-//W3C//DTD XHTML 1.0 Transitional//EN” “http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd”>

set_time_limit(0);

function _rand() {

       $length=26;

       $chars = “0123456789abcdefghijklmnopqrstuvwxyz”;

       $max = strlen($chars) – 1;

       mt_srand((double)microtime() * 1000000);

       $string = ”;

      

       for($i = 0; $i

              $string .= $chars[mt_rand(0, $max)];

       }

       return $string;

}

 

error_reporting(0);

ini_set(‘html_errors’,false);

ini_set(‘display_errors’,false);

 

mysql_pconnect(“localhost”, “root”, “password”) or

       die (“Could not connect” . mysql_error());

mysql_select_db(“company”);

mysql_query(“SET NAMES ‘UTF8′”);

 

if($_GET['page']){

       $page = $_GET['page'];

}else{

       $page = ’1′;

}

$HTTP_SESSION=_rand();

$HTTP_SESSION;

$HTTP_URL=”http://www.alibaba.com/corporations/jiangmen/CN——————————–/”.$page.”.html”;

$ch = curl_init();

curl_setopt ($ch,CURLOPT_URL,$HTTP_URL);

curl_setopt($ch,CURLOPT_RETURNTRANSFER,true);

curl_setopt($ch,CURLOPT_USERAGENT,”Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1; SV1; .NET CLR 1.1.4322; .NET CLR 2.0.50727)”);

$res = curl_exec($ch);

curl_close ($ch);

 

preg_match_all(‘/href\s*=\s*["|\']?([^\s"\'>]*).en.alibaba.com\”/i’,$res,$arr);  

 

foreach($arr[1] as $a=>$web){

 

       $HTTP_SESSION=_rand();

       $HTTP_SESSION;

       $HTTP_Server=$web;

       $HTTP_URL=”.en.alibaba.com/contactinfo.html”;

       $ch1 = curl_init();

       curl_setopt ($ch1,CURLOPT_URL,$HTTP_Server.$HTTP_URL);

       curl_setopt($ch1,CURLOPT_RETURNTRANSFER,true);

       curl_setopt($ch1,CURLOPT_USERAGENT,”Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1; SV1; .NET CLR 1.1.4322; .NET CLR 2.0.50727)”);

       $res1 = curl_exec($ch1);

       curl_close ($ch1);

 

       preg_match(“/contactName(.*?)/s”,$res1,$name);

       $name = strip_tags($name[1]);

       //$name = str_replace(“\”",”",$name);

       //$name = str_replace(“>”,”",$name);

       $name = trim($name);

 

       preg_match(“/Company Name:(.*?)/s”,$res1,$Cname);

       $Cname = trim(strip_tags($Cname[1]));

 

       preg_match(“/Street Address:(.*?)/s”,$res1,$Add);

       $Add = trim(strip_tags($Add[1]));

 

       preg_match(“/City:(.*?)/s”,$res1,$City);

       $City = trim(strip_tags($City[1]));

 

       preg_match(“/Province\/State:(.*?)/s”,$res1,$Pronvice);

       $Pronvice = trim(strip_tags($Pronvice[1]));

 

       preg_match(“/Country\/Region:(.*?)/s”,$res1,$Region);

       $Region = trim(strip_tags($Region[1]));

      

       preg_match(“/Zip:(.*?)/s”,$res1,$Zip);

       $Zip = trim(strip_tags($Zip[1]));

      

       preg_match(“/Telephone:(.*?)/s”,$res1,$Tel);

       $Tel = trim(strip_tags($Tel[1]));

      

       preg_match(“/Mobile Phone:(.*?)/s”,$res1,$Phone);

       $Phone = trim(strip_tags($Phone[1]));

      

       preg_match(“/Fax:(.*?)/s”,$res1,$Fax);

       $Fax = trim(strip_tags($Fax[1]));

      

       preg_match(“/Website:(.*?)/s”,$res1,$Web);

       $Web = trim(strip_tags($Web[1]));

 

$result = mysql_query(“

Explain JSON Web Tokens (JWT) and their use case in PHP APIs. Explain JSON Web Tokens (JWT) and their use case in PHP APIs. Apr 05, 2025 am 12:04 AM

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,

Explain the match expression (PHP 8 ) and how it differs from switch. Explain the match expression (PHP 8 ) and how it differs from switch. Apr 06, 2025 am 12:03 AM

In PHP8, match expressions are a new control structure that returns different results based on the value of the expression. 1) It is similar to a switch statement, but returns a value instead of an execution statement block. 2) The match expression is strictly compared (===), which improves security. 3) It avoids possible break omissions in switch statements and enhances the simplicity and readability of the code.
