说明：我计划使用fastapi +angular，实现​迷宫路径生成与求解

后端功能包括：
1.FastAPI搭建RESTful接口。写两个接口，
1.1生成迷宫，
1.2求解路径

前端功能包括
1.根据给定的长宽值，生成迷宫
2.点击按钮，刷新迷宫，生成新迷宫
3.点击按钮，可以给出正确的迷宫路径
4.增加开始按钮 和计时功能
5.鼠标拖拽绘制迷宫路径
6.绘制错误，弹窗提示失败，重新开始
7.拖拽绘制迷宫成功，弹窗提示成功，并给出分数

效果图：
在这里插入图片描述

step1:C:\Users\wangrusheng\PycharmProjects\FastAPIProject\main.py

from fastapi import FastAPI, HTTPException
from fastapi.middleware.cors import CORSMiddleware
from pydantic import BaseModel
from typing import List
import random
from collections import dequeapp = FastAPI()app.add_middleware(CORSMiddleware,allow_origins=["http://localhost:4200"],allow_credentials=True,allow_methods=["*"],allow_headers=["*"],

async def generate_maze(request: MazeRequest):try:maze = generate_maze_dfs(request.width, request.height)return {"maze": maze,"start": [0, 0],"end": [len(maze) - 1, len(maze[0]) - 1]}except Exception as e:raise HTTPException(status_code=500, detail=str(e))@app.post("/solve-maze/")
async def solve_maze(request: SolveRequest):try:path = solve_bfs(request.maze, tuple(request.start), tuple(request.end))return {"path": path}except Exception as e:raise HTTPException(status_code=500, detail=str(e))if __name__ == "__main__":import uvicornuvicorn.run(app, host="0.0.0.0", port=8000)

step2:后端部分写完了，一定要记得去postman里面测试，确保后端接口正确，然后再写前端，
这种能正常请求返回json就表示接口没问题，避免500，404，或者其他error问题

post请求：http://127.0.0.1:8000/solve-maze/{"detail": [{"type": "missing","loc": ["body"],"msg": "Field required","input": null}]
}post请求：http://127.0.0.1:8000/generate-maze/{"detail": [{"type": "missing","loc": ["body"],"msg": "Field required","input": null}]
}

step3:后端部分写完了，postman测试完成，接下来写前端angular
