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
进入5000端口显示如图，点击这个按钮，跳到自定义的/cool_form页面

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
