Question

我有简单的python应用程序，它使用post方法从html表单提交名称和电话。我在index.html中有这个：

<form action="http://127.0.0.1:5000/get_phone/" method = "POST">
First name:
<input type="text" name="firstname" >

Phone:
<input type="text" name="lastname" >

<input type="submit" value="Submit">
</form>

并拥有我的getPhone.py：

from flask import Flask
app = Flask(__name__)

@app.route('/get_phone/', methods=['POST', 'GET'])
def get_phone():
    if request.method == 'POST':
        print ('First name:', request.form['firstname'])
        print ('Phone:', request.form['lastname'])

    return 'Take a look at your terminal!'

if __name__ == '__main__':
    app.run()

但是当我提交表单时，我在浏览器中收到以下消息：

内部服务器错误

服务器遇到内部错误但无法完成   你的申请。服务器过载或出现错误   申请。

在我的控制台中我有这个：

127.0.0.1 - - [04/Feb/2015 22:26:22] "GET /get_phone/ HTTP/1.1" 500 -

如何解决这个问题？

UPD：consoleLog with debug = true：
