Flask g objects

1. What is the object g?

1. In the flask, to have a special g object stores user information, the full name of g is global.
2. G object where a request for all code, can all be used.

Assignment way

from flask import Flask, g, render_template, request
from ulits import login_log

app = Flask(__name__)

@app.route('/')
def hello_world():
    return 'index'

@app.route('/login/', methods=['GET', 'POST'])
def login():
    if request.method == 'GET':
        return render_template('login.html')
    else:
        username = request.form.get('username')
        password = request.form.get('password')
        if username == 'zhiliao' and password == '111111':
            g.username = username
            login_log()
            return '恭喜您！登录成功'
        else:
            return '登录名或密码错误!'


if __name__ == '__main__':
    app.run(debug=True, host='127.0.0.1', port=8081)

Called

from flask import g

def login_log():
    print('登录名为: {}'.format(g.username))

The difference between the object and the session 2.g

In my opinion, the biggest difference is, the object can be cross-session request as long as the session has not failed, request a different request will get to the same session

But the object is not g, g object does not need pipe expiration time, once a request to change a target g, or a re-assignment

G then how to use objects it? Look at the code.
