背景

续接上篇，VSCode的基金插件确实不错，不过盈亏查看用着感觉不对，多次购买同一基金后，基金持仓不会填了，而且我还想要更多的数据项，于是乎，自己倒腾个基金工具。

获取基金信息

获取基金的接口有很多，比如天天基金、腾讯、新浪以及其他证券金融公司网站。 这次我选择天天基金的接口，接口地址为:http://fundgz.1234567.com.cn/js/基金代码.js

接口测试：

GET http://fundgz.1234567.com.cn/js/012414.js HTTP/1.1

测试结果:

HTTP/1.1 200 OK

接口返回了基金名称、基金单位净值、基金估值、涨跌幅等信息，因此借此可以封装一个获取基金信息的模块
