Vue 3 - inject() 只能在设置或功能组件内部使用
Vue 3 - inject() can only be used inside setup or functional components
我不明白为什么会出现此错误。我正在尝试在组合函数中使用 Vuex 存储,但它一直向我抛出有关注入的错误(我什至没有使用注入)。我的应用程序向后端发出 await api 调用,如果出现错误,则调用我的组合函数。
[Vue warn]: inject() can only be used inside setup() or functional components.
inject @ runtime-dom.esm-bundler-9db29fbd.js:6611
useStore @ vuex.esm-bundler.js:13
useErrorHandling @ useErrorHandling.js:5
checkUserExists @ auth.js:53
这是我的组合函数
import { useStore } from 'vuex'
function useErrorHandling()
{
const store = useStore() // <-- this line
function showError(errorMessage) {
console.log(errorMessage)
}
return { showError }
}
export default useErrorHandling
如果我删除这一行,它就不会抛出该错误
// const store = useStore() // <-- this line
更新:函数是这样调用的。
/**
* Check if a user exists in database
*/
static async checkUserExists(data)
{
const { env } = useEnv()
const { jsonHeaders } = useHTTP()
const { showError } = useErrorHandling()
try {
let response = await fetch(`${env('VITE_SERVER_URL')}/auth/check-user-exists`, {
method: 'POST',
body: JSON.stringify(data),
headers: jsonHeaders,
})
if (!response.ok) {
let errorMessage = {
statusText: response.statusText,
statusCode: response.status,
body: '',
url: response.url,
clientAPI: 'api/auth.js @ checkUserExists',
}
const text = await response.text()
errorMessage.body = text
showError(errorMessage) // <-- here
return
}
response = await response.json()
return response.user_exists
} catch (error) {
alert('Error occured!')
console.log(error)
}
}
错误告诉您 useStore
是组合 API。来自 docs:
To access the store within the setup hook, you can call the useStore function. This is the equivalent of retrieving this.$store within a component using the Option API.
要在模块中使用 store
,您可以 import { store }
从创建它的模块中:
store.js
export const store = createStore({
...
})
其他模块
import { store } from './store'
