问题描述
我有一个简单的python应用程序，它使用post方法从html表单提交姓名和电话。我在index.html有这个：
< form action =http://127.0.0.1 ：5000 / get_phone /method =POST>
名字：
< input type =textname =firstname>
电话：
< input type =textname =lastname>
< input type =submitvalue =Submit>
< / form>
有我的 getPhone.py ：
from flask import Flask
app = Flask（__ name__）
@ app.route（ ''get_phone /'，methods = ['POST'，'GET']）
def get_phone（）：$ b $如果request.method =='POST'：
print ：'，request.form ['firstname']）
print（'Phone：'，request.form ['lastname']）
return'看看你的终端！
$ b $ if if __name__ =='__main__'：
app.run（）
$ b $但是，当我提交我的表单，我在我的浏览器中收到以下消息：
$ b
在我的控制台中，我有这个：
> *运行在http://127.0.0.1:5000/（按CTRL + C退出）
127.0.0.1 - - [04 / Feb / 2015 22:20:04]GET / get_phone / HTTP / 1.1 500 -
127.0.0.1 - - [04 / Feb / 2015 22:20:12]POST / get_phone / HTTP / 1.1500 -
127.0.0.1 - - [04 / Feb / 2015 22:26:22]GET / get_phone / HTTP / 1.1500 -
如何解决这个问题
$ b
UPD：consoleLog with debug = true：
*运行在http://127.0.0.1:5000/上（按CTRL + C退出）
*用stat
重新启动127.0.0.1 - - [04 / Feb / 2015 22:35:30]POST / get_phone / HTTP / 1.1500 -

解决方案
问题在于您没有导入请求。
像这样：
from flask import Flask，请求
I have simple python app which gets name and phone from html form submit using post method.I have this in my index.html:
<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>
And have my 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()
But when I submit my form with I get the following message in my browser:
In my console I have this:
> * Running on http://127.0.0.1:5000/ (Press CTRL+C to quit)
127.0.0.1 - - [04/Feb/2015 22:20:04] "GET /get_phone/ HTTP/1.1" 500 -
127.0.0.1 - - [04/Feb/2015 22:20:12] "POST /get_phone/ HTTP/1.1" 500 -
127.0.0.1 - - [04/Feb/2015 22:26:22] "GET /get_phone/ HTTP/1.1" 500 -
How to fix this?
UPD: consoleLog with debug = true:
* Running on http://127.0.0.1:5000/ (Press CTRL+C to quit)
* Restarting with stat
127.0.0.1 - - [04/Feb/2015 22:35:30] "POST /get_phone/ HTTP/1.1" 500 -

The issue is that you haven't imported request.Like this:
from flask import Flask, request
