试试：
from flask import Flask app = Flask(__name__) @app.route(‘/’) def index(): return ‘Index Page’ @app.route(‘/’) def hello(): return ‘Hello, World!’ |
效果：
http://115.29.173.126:5000/hello
->原来是自己不小心写错了
去改为：
from flask import Flask app = Flask(__name__) @app.route(‘/’) def index(): return ‘Index Page’ @app.route(‘/hello’) def hello(): return ‘Hello, World!’ |
即可：
继续去参考：
Quickstart — Flask Documentation (0.11)
找到中文文档：
https://www.ietf.org/rfc/rfc2068.txt
去加上：
@app.route(‘/login’, methods=[‘GET’, ‘POST’]) def login(): if request.method == ‘POST’: do_the_login() else: show_the_login_form() |
直接访问：
http://115.29.173.126:5000/login
结果出错：

The debugger caught an exception in your WSGI application. You can now look at the traceback which led to the error. To switch between the interactive traceback and the plaintext one, you can click on the “Traceback” headline. From the text traceback you can also create a paste of it. For code execution mouse-over the frame you want to debug and click on the console icon on the right side. You can execute arbitrary Python code in the stack frames and there are some extra helpers available for introspection:
