Vue代理模式和Nginx反向代理(Vue代理部署不生效)_nginx vue springboot 刷新路由失效 反向代理

在使用axios时，经常会遇到跨域问题。为了解决跨域问题，可以在 vue.config.js 文件中配置代理：

const { defineConfig } = require('@vue/cli-service')
module.exports = defineConfig({
  transpileDependencies: true,
  devServer: {
    port: 7070,
    proxy: {
      '/api': {
        target: 'http://localhost:8080/admin',
        pathRewrite: {
          '^/api': ''
        }
      }
    }
  }
})

axios的post请求示例：

axios.post('/api/employee/login',{
      username:'admin',
      password: '123456'
    }).then(res => {
      console.log(res.data)
    }).catch(error => {
      console.log(error.response)
    })

前端发送：http://localhost:7070/api/employee/login
经过代理转换为：http://localhost:8080/admin/employee/login

axios的get请求示例：

axios.get('/api/shop/status',{
        headers: {
          token: ‘xxx.yyy.zzz’
        }
      })

前端发送：http://localhost:7070/api/shop/status
经过代理转换为：http://localhost:8080/admin/shop/status

打包部署vue

npm run build
1

打包结束后生成dist文件夹

注意：打包时这个代理并不会跟着打包

假设我们将项目打包到的nginx地址是localhost地址，访问端口是80（80默认可省略）

那么这时候数据请求将请求的是http://localhost/api/employee/login地址，但是我们需要请求的接口是localhost:8080地址，这时候就需要用到nginx的反向代理了 。

首先进入配置文件

配置好了代理之后就可以重启服务器了
nginx将http://localhost/api/employee/login 转为http://localhost:8080/admin/employee/login
