fastapi用法

POST GET请求方法：

import time
import uvicorn
from fastapi import FastAPI, Body, Header, Form
from pydantic import BaseModel
from fastapi.responses import JSONResponse,HTMLResponse,FileResponse

app = FastAPI()
class Item(BaseModel):
    text_list:list

# POST请求
@app.post("/getRegion")
async def getRegion(text_list:Item):
    try:
        return {"success": True, "Msg": text_list.text_list}
    except Exception as e:
        return {"success": False, "Msg": str(e)}

#get请求
@app.get("/user/{id}")
def user(id):
    return {"id":id}

# get请求另一种方法
@app.get("/user")
def user(id,token=Header(None)):
    return {"id":id,"token":token}
# POST接收form表单
@app.post("/login")
def user(username=Form(None),password=Form(None)):
    return {"username":username,"password":password}

# 修改响应状态码
@app.get("/")
def user():
    return JSONResponse(content={"msg":"get user"},
                        status_code=202,
                        headers={"a":"b"})
# 返回网站
@app.get("/a")
def aaa():
    html_content = """
    <html>
        <body>aaa</body>
    </html>
    """
    return HTMLResponse(content=html_content)
# 返回图片
@app.get("/avatar")
def user():
    avatar = "./pic3.jpg"
    return FileResponse(avatar,
                        # filename="pic3.jpg"
                        )


# if __name__ == '__main__':
#     uvicorn.run(app=app, host="0.0.0.0", port=8000)
