从URL获取参数，在查询字符串中获取子字符串并将其存储在表中 [英] Get parameters from URL, get substrings in a query string and store them in a table

问题描述

我想获取URL中某些参数的值，我知道这个主意，但不知道如何获取它们.

I want to get the values of some parameters in a URL, I know the idea but I don't know how to do get them.

我有一个URL字符串:

I have an string that is an URL:

local url="fbconnect://success?to[0]=213322147507203&to[1]=223321147507202&request=524210977333164"

我想检测子字符串"to ["并获取数字293321147507203、293321147507202并将它们存储在表中.

I want to detect the sub-strings "to[" and get the numbers 293321147507203,293321147507202 and store them in a table.

我知道该过程是检测子字符串to [，然后获取为3个字符的子字符串(或6不确定是否从"to ["开头开始计数，然后获取数字，始终为15位数字.

I know the process is detect the sub-string to[ and then get the sub-string that is 3 character (or 6 not sure if it counts from the beginning of "to[" and then get the number, always is a 15 digit number.

推荐答案

local url="fbconnect://success?to[0]=213322147507203&to[1]=223321147507202&request=524210977333164"
local some_table = {}
for i, v in url:gmatch'to%[(%d+)]=(%d+)' do
   some_table[tonumber(i)] = v  -- store value as string
end
print(some_table[0], some_table[1]) --> 213322147507203 223321147507202
