我究竟做错了什么？ 似乎无法将参数传递给服务器
[英]what am i doing wrong? cant seem to pass a parameter to server
问题描述
I am trying to have user enter a number which will call a query and show the results in a table for user to compare, but when the user submits the form, the python program gets the input and get the results properly. 
我试图让用户输入一个数字，它将调用一个查询并在一个表中显示结果供用户比较，但是当用户提交表单时，python程序获取输入并正确获取结果。
In short, user enters a number and it generates a small table of results. 简而言之，用户输入一个数字，它会生成一个小的结果表。
Some reason the input is not been passed. 输入未被传递的一些原因。
Please check my work to see what is wrong. 请检查我的工作，看看有什么问题。
Here is main.py: 这是main.py：
from bottle import request, route, run, view
@route('/')
@view('index.html')
def index():
print request.GET.get('choice');
return dict(choice = request.method == 'GET');
run(host = 'localhost', port = 9988);

Move the code from the template to the index() function and pass the lists as dictionary values. 将代码从模板移动到index()函数，并将列表作为字典值传递。
In general, try to restrict the programming logic in a template to a minimum required to render data. 通常，尝试将模板中的编程逻辑限制为呈现数据所需的最小值。

I don't understand what this line is supposed to be doing: 我不明白这条线应该做什么：
return dict(choice = request.method == 'GET');
This is creating a dictionary with a single key, 'choice', whose value is either True if the request method is GET, or False otherwise. 这是使用单个键“choice”创建一个字典，如果请求方法是GET，则其值为True ，否则为False 。 I highly doubt that's what you meant. 我非常怀疑这就是你的意思。 Perhaps you meant this: 也许你的意思是：
return {'choice': request.GET.get('choice')}
