How Laravel references third-party (custom) libraries
想做一个网页抓取的功能,底层使用php的laravel框架。
这里使用phpQuery库来实现网页抓取,这里不做介绍。
需要了解的可以百度,或者等我填坑。
不能科学上网的可以直接点击我上传的下载包- -|怎么上传。。。自己百度吧,目前最新的版本是phpQuery-0.9.5.386
-------------------------------------
先申明下我用的版本:
laravel5.1;
phpQuery-0.9.5.386;
-------------------------------
开始以为只要把库整个包扔进laravel工程就能用了,果然是图样图森破。
鉴于laravel框架封装的良好行,这里需要设置laravel的autoload->class map
-------
1、首先在app目录下创建一个新的文件夹,命名libs(可自定义)
2、(可选)考虑到后面可能会引用很多库,so,在libs下再创建一个phpQuery文件夹
3、找到根目录下的composer.json文件
4、找到composer.json中定义的(看我备注)
"autoload": { "classmap": [ "database", "app/libs/phpQuery" //加我 加我 加我 ], "psr-4": { "App\\": "app/" } },
5、运行终端,cd到项目路径,执行
composer dumpautoload
--------------------------
然后就能在项目中愉快的使用phpQuery了,简单的用法如下:
use phpQuery;
phpQuery::newDocumentFile('http://www.baidu.com'); $companies = pq('body'); return $companies;
注:如果要再加其他第三方库,重复2-5的步骤即可。
以上就介绍了Laravel如何引用第三方(自定义)库,包括了方面的内容,希望对PHP教程有兴趣的朋友有所帮助。
