flask 服务器不稳定,Flask POST请求导致服务器崩溃

我试图在Flask中创建一个简单的api，第一步是获取POST-json数据。(我现在只想打印它)这是我的代码，当我用json数据请求/api时，它返回一个500错误。有没有想过为什么会这样？from flask import Flask, request, Response

app = Flask(__name__)

@app.route('/')

def root_response():

return "Hello World."

@app.route('/api', methods=['POST', 'GET'])

def api_response():

if request.method == 'POST':

return request.json

if __name__ == '__main__':

app.run()

curl命令：$ curl -H "Content-Type: application/json" --data @body.json http://127.0.0.1:5000/api

500 Internal Server Error

Internal Server Error

The server encountered an internal error and was unable to complete your request. Either the server is overloaded or there is an error in the application.

正文.json：{

"please": "print",

"me": "now"

}
