本文教大家怎么用php操作selenuim的webdriver来爬取基金数据

2022-08月更新，selenium4.4 版本的启动（把java跟chromedriver放在一起）：

./software/phantomjs --port=4444

先搭建selenium环境：selenium需要jdk环境，自己安装上去就行了，java -version可以查看你是否安装了，我下载的selenium是

目前的稳定版本 selenium-server-standalone-3.141.59.jar  可以在selenuim的官网下载：Downloads | Selenium

我用的是chrome浏览器，版本 79.0.3945.36（正式版本） （64 位）然后找到对应的webdriver版本，找到你的：

https://chromedriver.storage.googleapis.com/index.html

注意：你的webdriver一定要跟浏览器的版本一样哦！！！

把你下载的chromedriver.exe跟selenium-server-standalone-3.141.59.jar 放在同一个文件夹

然后启动selenium : 

java -jar selenium-server-standalone-3.141.59.jar 

爬取基金数据思路:

1.先爬目前市面上所有的基金，把数据存到数据库

2.遍历所有基金，然后分别爬取基金的历史数据

3.工具：yaf框架+selenuim+webdriver爬取基金历史数据，

4.关于selenium和webdriver怎么使用的可以参考https://github.com/facebook/php-webdriver

5.注意事项，不要爬太快，慢慢爬，我是每翻一页就休眠0.1秒，后来我取消了休眠，爬几百个基金后就报错了，又重新启动他。

然后又爬几百个又报错了，还是翻一页休眠0.1秒吧，这样慢慢爬就没有问题了。

基金历史数据：

基金数量：
