[英]How can I re-run Vue.js ApolloClient middleware?
In my main.js
I have some code that checks for the existence of a localStorage item. 在我的main.js
我有一些代码可以检查是否存在localStorage项。 If it has it, it will add an Authorization
header via middleware to the ApolloClient setup. 如果有,它将通过中间件向ApolloClient设置添加Authorization
标头。
However, if a localStorage item is later added , it's not present in the middleware of main.js
. 但是,如果稍后添加了localStorage项,则它不会出现在main.js
的中间件中。 A full page refresh is therefore required in order to get it to pick it up / know of its existence. 因此,需要进行整页刷新才能使其获取/了解其存在。
How can I run main.js
again (if that's even the solution) from a method in say, a component that signs the user in? 如何从一个方法中再次运行main.js
(如果这甚至是解决方案),例如,一个用户签名的组件?
Here's my main.js
: 这是我的main.js
:
import Vue from 'vue'
import ApolloClient, { createNetworkInterface } from 'apollo-client'
import VueApollo from 'vue-apollo'
import App from './App'
import router from './router'
import store from './store'
const networkInterface = createNetworkInterface({ uri: 'https://api.graph.cool/simple/v1/MY-ID-HERE' })
const requestToken = localStorage.getItem('TOKEN')
networkInterface.use([{
applyMiddleware (req, next) {
if (!req.options.headers) {
req.options.headers = {}
}
req.options.headers['Authorization'] = requestToken ? `Bearer ${requestToken}` : null
next()
}
}])
const apolloClient = new ApolloClient({
networkInterface
})
const apolloProvider = new VueApollo({
defaultClient: apolloClient
})
Vue.use(VueApollo)
/* eslint-disable no-new */
new Vue({
el: '#app',
template: '<App />',
components: {
App
},
apolloProvider,
router,
store
})
Hopefully you can understand what I'm trying to do? 希望你能理解我想要做什么?
Thanks 谢谢
I believe you need to move your requestToken
declaration inside the applyMiddleware
function. 我相信你需要在applyMiddleware
函数中移动你的requestToken
声明。 This way, you'll check local storage for a token every time a request is made. 这样,每次发出请求时,您都会检查本地存储是否有令牌。 Otherwise, it's only checked once, when the page is loaded and you end up seeing the behavior you described. 否则,它只会检查一次,当页面加载并且您最终看到您描述的行为时。
networkInterface.use([{ applyMiddleware (req, next) {
const requestToken = localStorage.getItem('TOKEN')
if (!req.options.headers) {
req.options.headers = {}
}
req.options.headers['Authorization'] = requestToken ? `Bearer ${requestToken}` : null
next() } }])
