一、打开界面
鼠标右键打开检查，方框里为你一个文小姐的征婚信息。。由此判断出为同步加载
点击elements，定位图片地址，方框里为该女士的url地址及图片地址
可以看出该女士的url地址不全，之后在代码中要进行url的拼接，看一下翻页的url地址有什么变化
点击第2页
https://www.csflhjw.com/zhenghun/34.html?page=2
点击第3页
https://www.csflhjw.com/zhenghun/34.html?page=3
可以看出变化在最后
做一下fou循环格式化输出一下。。一共10页
二、代码解析
1.获取所有的女士的url，xpath的路径就不详细说了。。
2.构造每一位女士的url地址
3.然后点开一位女士的url地址，用同样的方法，确定也为同步加载
4.之后就是女士url地址html的xpath提取，每个都打印一下，把不要的过滤一下
5.最后就是文件的保存
打印结果：
三、完整代码
