Python中的HTML输入数组解析（GAE） [英] HTML input array parsing in Python (GAE)

问题描述

我在HTML中有一个输入数组，如下所示：

 < input type =textname =p_item []> 
< input type =textname =p_item []> 
< input type =textname =p_item []> 
  

我想在Python中解析输入，我试着这样做， ：

  items = self.request.get（'p_item'）
 for n in range（1，len（项目））：
 self.response.out.write（'Item'+ n +'：'+ items [n]）
  

这样做的正确方法是什么？

解决方案

p>

 < input type =textname =p_item> 
< input type =textname =p_item> 
< input type =textname =p_item> 
  

并使用self.request.get_all（）方法 http://code.google.com/appengine/docs/python/tools/webapp/requestclass.html #Request_get_all

ps作为参考，没有关于GET / POST数据的数组概念，您的表单被转换为由'&'分隔的key = value字符串，例如

  p_item = 1& p_item = 3& p_item = 15 
  

等等，这取决于Web框架来解释一个参数是否是一个数组。

编辑：哎呀，只要阅读你已经知道的评论，哦：P

I'm two days in to Python and GAE, thanks in advance for the help.

I have an input array in HTML like this:

<input type="text" name="p_item[]">
<input type="text" name="p_item[]">
<input type="text" name="p_item[]">

I want to parse the input in Python, and I'm trying this, which isn't working:

items = self.request.get('p_item')
for n in range(1,len(items)):
  self.response.out.write('Item '+n+': '+items[n])

What is the correct way to do this?

解决方案

Change your html to this

<input type="text" name="p_item">
<input type="text" name="p_item">
<input type="text" name="p_item">

and use the self.request.get_all() method http://code.google.com/appengine/docs/python/tools/webapp/requestclass.html#Request_get_all

p.s. For reference, there is no concept of arrays for GET/POST data, your form gets transformed a key=value string separated by '&' e.g.

p_item=1&p_item=3&p_item=15

etc, it's up to the web framework to interpret whether a parameter is an array.

Edit: oops, just read the comments that you figured this out already, oh well :P
