1. 编译模式一定要设置为esnext,否则会报错:

Strict MIME type checking is enforced for module scripts per HTML spec.Expected a JavaScript module script but the server responded with a MIME type of "text/plain".

具体解释可以看vite官方文档:构建选项 | Vite 官方中文文档 

2.而且路由模式要改为hash模式:

import {
    createRouter,
    createWebHistory,
    createWebHashHistory,
    RouteRecordRaw,
} from 'vue-router'

// 全局路由
const router = createRouter({
    history: createWebHashHistory(), // 路由模式:history模式
    routes: routes,
})

3.flask的模板文件放置

flask项目根目录要有templates文件夹和static文件夹,用于存储vue打包后的模板文件和静态文件 

在flask中映射模板文件:

from flask import Flask, jsonify, request, render_template

app = Flask(__name__, static_url_path='/',
            static_folder='static', template_folder='templates')


@app.route("/")
def index():
    return render_template("index.html")


# @app.route("/v1/server/nfcadduser", methods=["POST"])
# def add_user_nfc():
#     data_json = request.form  # 获取POST请求中的data参数
#     print(f"接收到的请求参数是: {data_json}")
#     data = {
#         "code": 200,
#         "data": data_json,
#         "msg": "操作成功"
#     }
#     return jsonify(data)


if __name__ == '__main__':
    app.run(host="0.0.0.0", port=9080)
