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...
一般对于Request Body不会通过get提交,对于get提交的参数一般称为是查询参数。所以,如果是通过POTS,PUT等方式提交的参数信息,我们一般是放到Request Body来提交到我们的后端。 对于如何接收和校验请求体,FastApi提供的形式是使用:from pydantic import BaseModel 示例如下: 代码语言:javascript 代码运行次数:0 运行 AI代码...

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....

Right now the API can only return the data it wants to. You have no say in what data is returned. For example, consider the following list of items represented as dictionaries in Python. Now add the following code to your API. You can either…
