通常以前的话,在bottle,通常直接的request.body 或 request.json就可以获取客户端部提交的信息了。 在Fastapi假设客户端提交的参数是这样的形式: { "item": { "name": "Foo", "description": "The pretender", "price": 42.0, "tax": 3.2 }, "user": { "username": "dave", "full_name": "Dave ...
除了GET请求,我们还可以发送POST请求来向服务器发送数据。下面的示例演示了如何使用FastAPI发送POST请求: importrequests url=" data={"name":"John Doe","email":"johndoe@example.com"}response=requests.post(url,json=data)ifresponse.status_code==201:print("用户创建成功!")else:print("请求失败") 1. 2...

POST http://localhost:8000/items/?query_param=test Content-Type: application/json { "name": "example", "price": 9.99 } 在上述示例中,查询参数query_param的值为test,POST请求的正文中提供了一个JSON对象作为数据。 FastAPI应用程序将使用POST请求中的数据创建一个Item对象,并将查询参数query_param作为函数...
a minimal API with a single endpoint(/) that responds to a GET request with the message "Hello world". We instantiate a FastAPI class and use decorators to tell the server which HTTP methods should trigger which function for a response, just like with the Flask microframework, for example....
@app.get("/") async def read_root(request: Request): message = "Hello from FastAPI!" return templates.TemplateResponse("index.html", {"request": request, "message": message}) 在这个修改后的代码中,我们导入了Request类、HTMLResponse类和Jinja2Templates类,我们还导入了os库,以便获取项目目录,我们...
