我有一个装饰员，想让它newname通过protected()并显示，该怎么办？
如果name='Jan'在装饰器中newname与Jan hello!!!and 相等，则newname可以print(newname)在protected()
我的代码
app.py
@app.route('/protected')
@lookname
def protected():
return jsonify({'message': 'This is only available for people with valid tokens!'})
lookname.py
def lookname(f):
@wraps(f)
def decorated(*args, **kwargs):
name = request.cookies.get('name')
newname = name + ' hello!!!'
return f(*args, **kwargs)
return decorated
我要这样
@app.route('/protected')
@lookname
def protected():
print(newname)
return jsonify({'message': 'This is only available for people with valid tokens!'})
您可以g用来携带绑定到请求上下文的任何信息位。
from flask import g
def lookname(f):
@wraps(f)
def decorated(*args, **kwargs):
name = request.cookies.get('name')
g.newname = name + ' hello!!!'
return f(*args, **kwargs)
return decorated
然后在protected：
from flask import g
@app.route('/protected')
@lookname
def protected():
print(g.newname)
# ...
