vue2调用接口

初见vue2，试探了两天，第一次正经接触前端，蛮兴奋的。

创建接口

import uvicorn
from fastapi import FastAPI, Header
from typing import Union
from typing_extensions import Annotated
from fastapi.middleware.cors import CORSMiddleware
app = FastAPI()

# 这一块是为了 vue2 能够跨域访问
app.add_middleware(
    CORSMiddleware,
    allow_origins=['*'],
    allow_credentials=True,
    allow_methods=["*"],
    allow_headers=["*"],
)

@app.get("/read")
async def read(Authorization: Annotated[Union[str, None], Header()] = None):
    if Authorization == 'SG68ER4G68SE1F':
        return {
            "List": [
                "{\"dep\": \"ANY\", \"arr\": \"YOU\", \"depTime\": \"2021-05-21 13:14\", \"arrTime\": \"2021-05-20 13:14\", \"flightNum\": \"AN2199\", \"email\": \"demo@anyi.com\", \"persioner\": \"anyiya/lake\", \"date\": \"2023-08-10 15:58:35\"}",
                "{\"dep\": \"ANY\", \"arr\": \"YOU\", \"depTime\": \"2021-05-21 13:14\", \"arrTime\": \"2021-05-20 13:14\", \"flightNum\": \"AN2199\", \"email\": \"demo@anyi.com\", \"persioner\": \"anyiya/lake\", \"date\": \"2023-08-10 15:58:35\"}",
                "{\"dep\": \"ANY\", \"arr\": \"YOU\", \"depTime\": \"2021-05-21 13:14\", \"arrTime\": \"2021-05-20 13:14\", \"flightNum\": \"AN2199\", \"email\": \"demo@anyi.com\", \"persioner\": \"anyiya/lake\", \"date\": \"2023-08-10 15:58:33\"}",
                "{\"dep\": \"ANY\", \"arr\": \"YOU\", \"depTime\": \"2021-05-21 13:14\", \"arrTime\": \"2021-05-20 13:14\", \"flightNum\": \"AN2199\", \"email\": \"demo@anyi.com\", \"persioner\": \"anyiya/lake\", \"date\": \"2023-08-10 15:58:32\"}"
            ]
        }
    else:
        return False

lock = "lock"
@app.get("/unlock")
async def unlock(Authorization: Annotated[Union[str, None], Header()] = None):
    if Authorization == 'SG68ER4G68SE1F':
        global lock
        lock = "unlock"
        return True
    else:
        return False

@app.get("/relock")
async def relock(Authorization: Annotated[Union[str, None], Header()] = None):
    if Authorization == 'SG68ER4G68SE1F':
        return lock
    else:
        return False

@app.get("/now")
async def getnow(Authorization: Annotated[Union[str, None], Header()] = None):
    if Authorization == 'SG68ER4G68SE1F':
        return {"status": "2021-05-20 13:19:23 4. In the sky"}
    else:
        return False

if __name__ == "__main__":
    uvicorn.run(app, host="0.0.0.0", port=9876)

部署vue2

# 克隆项目
git clone https://github.com/PanJiaChen/vue-admin-template.git
# 进入项目目录
cd vue-admin-template
# 安装依赖
apt install -y npm
npm install
# 建议不要直接使用 cnpm 安装以来，会有各种诡异的 bug。可以通过如下操作解决 npm 下载速度慢的问题
npm install --registry=https://registry.npm.taobao.org
# 安装请求接口需要的依赖
npm install qs -S
npm install axios -S
# 启动服务
npm run dev
# 默认地址
http://ip:9528

文件目录

简单了解下文件目录，方便我们接下来“调参”

vue-base 项目名称
- node_modules 项目依赖模块，一般不修改
- public 单入口文件index.html 在项目打包webpack的直接打包到dist文件里
- src 前端要写的文件 -资源文件
  - assets 静态资源 css、js、images...
  - components 公共组件
  - App.vue 根组件
  - main.js 核心入口文件配置（挂载vue实例）
  - router 配置路由
  - views 编辑所有组件
  - api 接口请求文件

我们图快

src/main.js 下导入包

import Axios from 'axios'
import qs from 'qs'
Vue.prototype.axios = Axios    //全局注册，使用方法为:this.$axios
Vue.prototype.qs = qs          //全局注册，使用方法为:this.qs

src/router/index.js 下增加页面
scr/views 下创建对应路径与index.vue
简单了解一下index.vue，包含三个模块
- template 其中写 html
- script 其中写js
- style 其中写css

index.vue

<template>
    <div>
        <!-- 1. 当前状态 -->
        <div class="status-container"  v-if="apiResponse">
            <transition name="fade-slide">
                <p class="status-data">当前进度：{{ apiResponse }}</p>
            </transition>
        </div>
        <!-- 2. 飞行列表 -->
        <el-table :data="list" border highlight-current-row>
            <el-table-column align="center" label="序号" width="60">
                <template slot-scope="scope">
                    {{ scope.$index + 1 }}
                </template>
            </el-table-column>
            <el-table-column align="center" label="起飞地" width="90">
                <template slot-scope="scope">

            </el-table-column>
            <el-table-column align="center" label="邮箱号" width="300">
                <template slot-scope="scope">
