Flask:通过Response对象发送数据和状态代码 [英] Flask: Sending data and status code through a Response object

问题描述

我正在用Flask编写通过API相互交互的微服务.

I am writing Microservices in Flask that interact with each other through API.

在发出POST请求时，我能够通过Response对象返回状态代码.有什么方法可以从此函数作为JSON返回数据?

On making a POST request, I am able to return the status code through the Response object. Is there any way that I can return data from this function as JSON ?

from flask import Flask, Response

@app.route('/login', methods=['POST'])
def login():
   # Set the status code
   response = Response(status=200)

   # How can I return a JSON in my response object as {'username': 'febin'} ?

   return response

推荐答案

只需使用 jsonify(). 此方法采用任何可序列化的数据类型(例如，在以下示例中，我使用了字典 data ).

Simply use jsonify() from flask package. This method takes any serializable data type (for example I have used dictionary data in the following example).

from flask import jsonify

@app.route('/login', methods=['POST'])
def login():
    data = {'name': 'nabin khadka'}
    return jsonify(data)

要返回状态码，只需在返回的末尾返回即可，如下所示:

To return a status code, simply return it at the end of the return as below:

return jsonify(data), 200
