代码如下
_init_.py
from flask import Flask, request, url_for, redirect, render_template
app = Flask(__name__)
@app.route('/')
def index():
return render_template('index.html')
@app.route('/cool_form', methods=['GET', 'POST'])
def cool_form():
if request.method == 'POST':
# do stuff when the form is submitted
# redirect to end the POST handling
# the redirect can be to the same route or somewhere else
return redirect(url_for('index'))
# show the form, it wasn't submitted
return render_template('cool_form.html')
index.html
<!doctype html>
<html>
<body>
<p><a href="{{ url_for('cool_form') }}" rel="external nofollow" >Check out this cool form!</a></p>
</body>
</html>
cool_form.html
<!doctype html>
<html>
<body>
<form method="post">
<button type="submit">Do it!</button>
</form>
</html>
运行结果

在我的程序里我实现了在web页面点击加法器或者除法器按钮进入相应页面
