Dva: 刷新页面src/index.js重复执行

Created on 25 Sep 2017 · 2Comments · Source: dvajs/dva

偶然发现在自己项目里的model在加载时，subscriptions里面dispatch的effects里面的网络请求在chrome开发工具里观察会发现请求重复发送了一次(包括用于hmr的websocket也是)，排查后发现刷新页面后src/index.js执行了两次。

Code to reproduce the issue: (请提供可复现的代码或者步骤)

> dva new test  
> cd test

src/index.js:

console.log(123)

npm start

Expected behavior: (预期的正常效果)

控制台只log一次123

Actual behavior: (实际效果)
