mutation中修改state中的状态值，却报[vuex] do not mutate vuex store state outside mutation handlers.
网上百度说是在mutation外修改state中的状态值，会报下列错误，可我明明在mutations中修改的状态值，还是报错
![mutation中修改state中的状态值，却报[vuex] do not mutate vuex store state outside mutation handlers.](/default/index/img?u=aHR0cHM6Ly93d3cuaWNvZGU5LmNvbS9pL2wvP249MjAmaT1ibG9nLzg5Mjc0MC8yMDIwMDYvODkyNzQwLTIwMjAwNjI2MTE1ODQ5NjAyLTQzOTkyMTMzNy5wbmc= "mutation中修改state中的状态值，却报[vuex] do not mutate vuex store state outside mutation handlers.")

接着百度，看到和我类似的问题，说mutations中只能用同步代码，异步用actions,我试着把修改值放在请求外面，结果不报错了![mutation中修改state中的状态值，却报[vuex] do not mutate vuex store state outside mutation handlers.](/default/index/img?u=aHR0cHM6Ly93d3cuaWNvZGU5LmNvbS9pL2wvP249MjAmaT1ibG9nLzg5Mjc0MC8yMDIwMDYvODkyNzQwLTIwMjAwNjI2MTE1ODUwNDM3LTIwMzAwNDMwOTEucG5n "mutation中修改state中的状态值，却报[vuex] do not mutate vuex store state outside mutation handlers.")
