vue3+vite+ts配置多个代理并解决报404问题

news2024/11/17 19:32:29

之前配置接口代理总是报404,明明接口地址是对的但还是报是因数写法不对;用了vue2中的写法

pathRewrite改为rewrite

根路径下创建env文件根据自己需要名命

.env.development文件内容

# just a flag
ENV='development'

# static前缀
VITE_APP_PUBLIC_PREFIX=""
# 基础模块
VITE_APP_BASIC_PREFIX='/basicSetting'
# 任务模块
VITE_APP_TASK_PREFIX='/task'

# 网关
VITE_APP_GATEWAY_PREFIX='/gateway/admin'
# 主题
VITE_APP_THEME=light


# vue-cli uses the VITE_CLI_BABEL_TRANSPILE_MODULES environment variable,
# to control whether the babel-plugin-dynamic-import-node plugin is enabled.
# It only does one thing by converting all import() to require().
# This configuration can significantly increase the speed of hot updates,
# when you have a large number of pages.
# Detail:  https://github.com/vuejs/vue-cli/blob/dev/packages/@vue/babel-preset-app/index.js
VITE_CLI_BABEL_TRANSPILE_MODULES=true

在vite.config.ts中配置poxy代理

import proxyConfig from './proxy'
const viteConfig = defineConfig(({ mode }) => {
 
  return {
    server: {
      host: '0.0.0.0', //解决“vite use `--host` to expose”
      port: 8080,
      open: true,
      proxy: proxyConfig
    }

  }
})
export default viteConfig

创建proxy.ts文件

import { ProxyOptions } from 'vite'

import { loadEnv } from 'vite'

const env = loadEnv('development', process.cwd())

const proxies: Record<string, ProxyOptions> = {
  // 任务模块
  [env.VITE_APP_TASK_PREFIX as string]: {
    target: 'http://xxx:31249', // 目标地址 --> 服务器地址
    changeOrigin: true, // 允许跨域
    rewrite: (path) => path.replace(new RegExp(`^${env.VITE_APP_TASK_PREFIX}`), '')
  },
  [env.VITE_APP_GATEWAY_PREFIX as string]: {
    target: 'http://192.168.8.xx:8080', // 目标地址 --> 服务器地址
    changeOrigin: true, // 允许跨域
    rewrite: (path) => path.replace(new RegExp(`^${env.VITE_APP_GATEWAY_PREFIX}`), '')
  }
  // 添加其他代理配置
}

export default proxies

api.ts接口使用

import request from '@/request/request'
import settings from '@/settings'
export function getTaskList(data: any): Res<any> {
  return request({
    url: settings.taskPrefix + '/adm/detectionTasks/page',
    method: 'post',
    data
  })
}

其中的settings.ts文件可以不用封装直接写你的env就行;也可以像我一样封装

export default {
  /**
   * 任务模块
   */
  taskPrefix: import.meta.env.VITE_APP_TASK_PREFIX,

  /**
   *  网关服务文件前缀
   */
  gatewayPrefix: import.meta.env.VITE_APP_GATEWAY_PREFIX
}

页面中调用接口

import { getTaskList } from '@/api'
 const param = {
          entity: {},
          betweenCondition: {},
          page: {
            page: 1,
            pageSize: 10
          }
        }
        getTaskList(param)
          .then((res) => {
            console.log(res)
          })
          .catch((err) => {
            console.log(err)
          })

效果:
