When I type /login as url,it will go wrong
For example:
from flask import Flask ,url_for,render_template,request
app = Flask(__name__)
@app.route('/login')
def index():
return "index"
if __name__== "__main__":
app.run()
The error turn out to be like this:
Not Found.
The requested URL was not found on the server.
When I replace /login with /login/ or any other words like /log , it will be all right. How does that happen?
