【vue-element-admin】登录接口对接自己的后端, .NET Core Web API 6

• vue-element-admin 登录接口对接
• 后端基于.NET Core Web API 6
• EFcore 和后端数据链接
• Jwt 认证

• Core + Vue 后台管理基础框架
• vue-element-admin-site

• 不要配置HTTPS
• 配置EFCore
• 配置跨越
• 配置JWT
• 后台运行程序

• .env.development

VUE_APP_BASE_API = '/dev-api'

• vue.config.js

  devServer: {
    'proxy': {
      '/api': {
        target: 'http://localhost:5172',
        changeOrigin: true
      }
    }
  },

• src/api/user.js 修改接口，因为用的baseURL，所已不是全局配置

import request from '@/utils/request'

export function login(data) {
  return request({
    baseURL: 'http://localhost:5172/api/user',
    url: '/login',
    method: 'post',
    data
  })
}

export function getInfo(token) {
  return request({
    baseURL: 'http://localhost:5172/api/user',
    url: '/info',
    method: 'get',
    params: { token }
  })
}

export function logout() {
  return request({
    baseURL: 'http://localhost:5172/api/user',
    url: '/logout',
    method: 'post'
  })
}

• store/modules/user.js

import { login, logout, getInfo } from '@/api/user'
import { getToken, setToken, removeToken } from '@/utils/auth'
import router, { resetRouter } from '@/router'

const state = {
  token: getToken(),

        commit('SET_TOKEN', data.token)
        setToken(data.token)
        resolve()
      }).catch(error => {

        }

        commit('SET_ROLES', roles)
        commit('SET_NAME', name)

• 用utils/request.js

  timeout: 5000 // request timeout
})

// request interceptor
service.interceptors.request.use(
  config => {
    // do something before request is sent

    if (store.getters.token) {
      // let each request carry token
      // ['X-Token'] is a custom headers key
      // please modify it according to the actual situation
      config.headers['Authorization'] = 'Bearer ' + getToken()
    }
    return config
  },
  error => {
    // do something with request error
    console.log(error) // for debug
    return Promise.reject(error)
  }
)

// response interceptor
service.interceptors.response.use(
