当前为大纲的内容：待完善中
1. axios
axios 安装
npm install axios
参考文档
https://www.kancloud.cn/yunye…
示例 demo
https://cn.vuejs.org/v2/cookb…
2. flask
构建 api:
from flask import Flask, render_template,jsonify
from flask_cors import CORS
app = Flask(__name__,
static_folder = “./dist/static”,
template_folder = “./dist”)
cors = CORS(app, resources={“/api/*”: {“origins”: “*”}})
from random import *
@app.route(‘/api/random’)
def random_number():
response = {
‘randomNumber’: randint(1, 100)
}
return jsonify(response)
在 jupyter_notebook 中运行服务
from werkzeug.serving import run_simple
run_simple(‘0.0.0.0’, 9001, app)
3. 在 vue 中调用，并显示
模板部分
<template>
<div>
欢迎来到首个测试页面
<p>Random number from backend: {{randomNumber}}</p>
<button @click=”getRandom”>New random number</button>
<p>{{orgdata}}</p>
<foot-nav v-bind:class=”{‘isIndex’:isIndexNow}”></foot-nav>
</div>
</template>
js 脚本部分
<script>
import FootNav from “../components/footer.vue”;
import axios from ‘axios’
export default {
components: {
FootNav
},
methods: {
getRandomInt (min, max) {
min = Math.ceil(min)
max = Math.floor(max)
return Math.floor(Math.random() * (max – min + 1)) + min
},
getRandom () {
// this.randomNumber = this.getRandomInt(1, 100)
this.randomNumber = this.getRandomFromBackend()
},
getRandomFromBackend () {
const path = `http://localhost:9001/api/random`
axios.get(path)
.then(response => {
this.randomNumber = response.data.randomNumber
this.orgdata = response.data
})
.catch(error => {
console.log(error)
})
}
},
data(){
return{
isIndexNow: true,
randomNumber: 0,
orgdata:null
}
}
}
</script>
css 脚本部分，未学习，不过就是页面丑一点而已，问题不大，回头再学把。
