from flask import Flask, url_for
from werkzeug.utils import redirect
app = Flask(__name__)
@app.route('/admin')
def hello_admin():
return 'Hello Admin'
@app.route('/guest/')
def hello_guest(guest):
return 'Hello %s as Guest' % guest
@app.route('/user/')
def hello_user(name):
if name =='admin':
return redirect(url_for('hello_admin'))
else:
return redirect(url_for('hello_guest'), guest = name)
if __name__ == '__main__':
app.run(debug=True)
1、运行 显示 Hello Admin 运行正常
2、但是运行
显示如下错误:TypeErrorTypeError: hello_user() missing 1 required positional argument: 'name'
3、再次运行http://127.0.0.1:5000/user/admin
显示如下错误:Not FoundThe requested URL was not found on the server. If you entered the URL manually please check your spelling and try again.
4、再次运行
显示如下错误:Not FoundThe requested URL was not found on the server. If you entered the URL manually please check your spelling and try again.
第3、4次运行中是不是我的输入是错误导致的?那么参数应该怎么传呢?
5、因为以上代码是教程中到源代码,应该是没有错的。
后来我修改了源代码中@app.route('/user/<name>')加入了<name>这个参数。
运行 和 都显示Hello Admin 运行正常。
但是运行http://127.0.0.1:5000/user/kjkj
显示如下错误:TypeErrorTypeError: redirect() got an unexpected keyword argument 'guest'
请问问题到底出在哪里呢??
