简易flask框架入门之服务器返回客户端的响应对象并且手动创建response对象

from flask import Flask,make_response

app = Flask(__name__)

@app.route('/')

def hello_world():

    # 一. 直接返回

    # 1. 返回, 响应体

    #    return "hello world"

    # 2. 返回, 响应体 + 状态码

        return "hello world","666bigererror"

    #

    # 3. 返回响应体 + 状态码 + 响应头

        return "helloworld",666,{"Content-Type":"application/json"}

    # 二手动创建response对象

    response = make_response("helloworld")

    response.status = "888 bigererror"

    response.headers["Content-Type"] = "application/json"

    response.headers["name"] = "banzhang"

    return response

if __name__ == '__main__':

    app.run(debug=True)
