Tips for using route interceptors in uniapp
In uniapp development, route interceptors are a very commonly used function. Route interceptors allow us to perform some specific operations before routing jumps, such as permission verification, page passing parameters, etc. In this article, we will introduce the tips for using route interceptors in uniapp and provide specific code examples.
- Create a route interceptor
First, we need to create a route interceptor in the uniapp project. The creation method is as follows:
Create an interceptors folder in the project root directory, and then create a router.js file in the folder. The router.js file will serve as our route interceptor.
- Implement route interceptor
In the router.js file, we can define multiple interceptor functions through Vue.prototype.$router provided by uni-app .beforeEach method to implement route interception. The specific code is as follows:
import Vue from 'vue'
import Router from 'uni-simple-router'
Vue.use(Router)
const router = new Router({
routes: []
})
// 全局前置路由守衛(wèi)
router.beforeEach((to, from, next) => {
// 在這里可以進(jìn)行權(quán)限的驗(yàn)證，比如判斷用戶是否登錄
// 示例：判斷用戶是否登錄，如果沒(méi)有登錄，則跳轉(zhuǎn)到登錄頁(yè)
if (!uni.getStorageSync('token') && to.path !== '/login') {
next({ path: '/login' })
} else {
next()
}
})
export default routerIn the above code example, we determine whether the user is logged in. If not, jump to the login page. Otherwise, proceed directly to the next step.
- Configuring route interceptor
To apply the route interceptor just created in uniapp, we need to configure it in the main.js file. The specific code is as follows:
import Vue from 'vue'
import App from './App'
import router from './interceptors/router'
Vue.config.productionTip = false
App.mpType = 'app'
const app = new Vue({
...App
})
app.$mount()
// 掛載路由
Vue.prototype.$router = routerIn the above code example, we introduced the created routing interceptor through import and mounted it to the Vue instance through the Vue.prototype.$router method.
- Route jump
Now, we can perform route jump operations in uniapp and trigger route interceptors. The specific code example is as follows:
// 在頁(yè)面中通過(guò)點(diǎn)擊按鈕進(jìn)行路由跳轉(zhuǎn)操作
<template>
<view>
<button @click="gotoLogin">跳轉(zhuǎn)到登錄頁(yè)</button>
</view>
</template>
<script>
export default {
methods: {
gotoLogin() {
uni.navigateTo({
url: '/pages/login/login'
})
}
}
}
</script>In the above code example, we use the uni.navigateTo method to perform routing jump operations and specify the page to jump to.
Through the above steps, we have completed the use of routing interceptor in uniapp. By defining interceptor functions and configuring them, we can perform permission verification and other operations before routing jumps, thereby improving application security and user experience.
Summary
This article introduces the usage skills of routing interceptors in uniapp and provides specific code examples. By using route interceptors, we can perform some specific operations before routing jumps, such as permission verification, page passing parameters, etc. In uniapp development, reasonable use of route interceptors will bring us a better development experience and user experience.

What are the disadvantages of uniapp
Apr 06, 2024 am 04:06 AM
UniApp has many conveniences as a cross-platform development framework, but its shortcomings are also obvious: performance is limited by the hybrid development mode, resulting in poor opening speed, page rendering, and interactive response. The ecosystem is imperfect and there are few components and libraries in specific fields, which limits creativity and the realization of complex functions. Compatibility issues on different platforms are prone to style differences and inconsistent API support. The security mechanism of WebView is different from native applications, which may reduce application security. Application releases and updates that support multiple platforms at the same time require multiple compilations and packages, increasing development and maintenance costs.
What is the difference between uniapp and flutter
Apr 06, 2024 am 04:30 AM
UniApp is based on Vue.js, and Flutter is based on Dart. Both support cross-platform development. UniApp provides rich components and easy development, but its performance is limited by WebView; Flutter uses a native rendering engine, which has excellent performance but is more difficult to develop. UniApp has an active Chinese community, and Flutter has a large and global community. UniApp is suitable for scenarios with rapid development and low performance requirements; Flutter is suitable for complex applications with high customization and high performance.

Which one is better, uniapp or mui?
Apr 06, 2024 am 05:18 AM
Generally speaking, uni-app is better when complex native functions are needed; MUI is better when simple or highly customized interfaces are needed. In addition, uni-app has: 1. Vue.js/JavaScript support; 2. Rich native components/API; 3. Good ecosystem. The disadvantages are: 1. Performance issues; 2. Difficulty in customizing the interface. MUI has: 1. Material Design support; 2. High flexibility; 3. Extensive component/theme library. The disadvantages are: 1. CSS dependency; 2. Does not provide native components; 3. Small ecosystem.
Which is better, uniapp or native development?
Apr 06, 2024 am 05:06 AM
When choosing between UniApp and native development, you should consider development cost, performance, user experience, and flexibility. The advantages of UniApp are cross-platform development, rapid iteration, easy learning and built-in plug-ins, while native development is superior in performance, stability, native experience and scalability. Weigh the pros and cons based on specific project needs. UniApp is suitable for beginners, and native development is suitable for complex applications that pursue high performance and seamless experience.
