/1 前言/

受疫情的影响，很多电影院现在都倒闭关门。最近好像听说电影院要开工了，快来看一看最近有什么刚上映的电影 ！

/2 项目目标/

    获取猫眼电影的即将上映的电影详情。

/3 项目准备/

软件：PyCharm

需要的库：requests、lxml、random、time

插件：Xpath

网站如下：

点击下一页的按钮，观察到网站的变化分别如下：

点击下一页时，页面每增加一页offset=()每次增加30，所以可以用{}代替变换的变量，再用for循环遍历这网址，实现多个网址请求。

/4 项目实现/

1、定义一个class类继承object，定义init方法继承self，主函数main继承self。导入需要的库和网址，代码如下所示。

2、随机产生UserAgent。

3、发送请求，获取页面响应。

4、xpath解析一级页面数据，获取页面信息。

1）基准xpath节点对象列表。

2）依次遍历每个节点对象，提取数据。

5、定义movie，保存打印数据。

6、random.randint()方法，设置时间延时。

7、调用方法，实现功能。

/5 效果展示/

1、点击绿色小三角运行输入起始页，终止页。

2、运行程序后，结果显示在控制台，如下图所示。

3、点击蓝色下载链接, 网络查看详情。

/6 小结/

1、不建议抓取太多数据，容易对服务器造成负载，浅尝辄止即可。

2、本文基于Python网络爬虫，利用爬虫库，实现爬取猫眼电影。

3、欢迎大家积极尝试，有时候看到别人实现起来很简单，但是到自己动手实现的时候，总会有各种各样的问题，切勿眼高手低，勤动手，才可以理解的更加深刻。

4、如果需要本文源码的话，请在后台回复“猫眼电影”四个字进行获取，觉得不错，记得给个star噢。
