用PHP抓取淘宝商品的用户晒单评论+图片实例
为什么想起来做这个功能?是因为前段时间在做一个淘客网站的时候,想到是否能抓取到淘宝商品的买家秀呢?经过一番折腾发现,淘宝商品用户评价信息是通过Ajax来调取的,通过嗅探网址发现,评论数据的请求接口是:
https://rate.tmall.com/list_detail_rate.htm?itemId=524394294771&spuId=341564036&sellerId=100414600&order=3¤tPage=1&append=0&content=1&tagId=&posi=&picture=1&callback=jsonp2339
其实上面很多参数也很容易理解,itemId是商品的ID,currentPage是当前页,picture为1时显示有图的评价,既然是抓取买家秀,那么picture参数一定要为1了。
如果你直接去访问上面的接口时,会得到如下图所示的请求结果:
看到请求结果是jsonp格式我就蛋碎了,我不知道如何去解析,但是换种思路,直接用PHP的正则去解析也未尝不可嘛,通过尝试,已经正确的能够解析到评论内容和买家秀的图片内容,如图:
效果不错,代码实现了评论内容的抓取、买家秀图片的抓取,代码奉上:
".str_replace('","rateDate":"',' ',str_replace('","reply"','',str_replace('"rateContent":"','',$matchcomments_only[0]))).""; $pattern3 = '/img.alicdn(.+?).jpg/is'; preg_match($pattern3, $match[0][$i], $matchpic_only); echo '';}/*匹配一张图片$pattern = '/"pics"(.+?)","position"/is';preg_match_all($pattern, $texts, $matchpic);for($i=0;$i
".$matchpic_only[0]."";}*//*匹配所有图片$pattern = '/"pics"(.+?)","position"/is';preg_match_all($pattern, $texts, $matchpic);for($i=0;$i "; foreach($arr as $newstr){ echo ' '; } echo "";}*/?>
有什么解析jsonp格式的好方法呢?求大神~~~

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.

Session hijacking can be achieved through the following steps: 1. Obtain the session ID, 2. Use the session ID, 3. Keep the session active. The methods to prevent session hijacking in PHP include: 1. Use the session_regenerate_id() function to regenerate the session ID, 2. Store session data through the database, 3. Ensure that all session data is transmitted through HTTPS.
