将查询字符串解析为结构化NSDictionary [英] Parse Query String into a Structured NSDictionary

问题描述

我有一个查询字符串： a = 1& b = 2& c [1] = 3& c [2] = 4 等...

I have a query string: a=1&b=2&c[1]=3&c[2]=4 etc…

我想要一个NSDictionary，其中 a => 1 ， b => 2，c =>。 [3,4] 。请注意，c的值是一个数组。它也应该能够处理像 c [1] [2] = 5 这样的数组来创建数组 c => [[5]] 。

I want a NSDictionary where a => 1, b => 2, c => [3,4]. Notice that that the value for c is an array. It should also be able to handle something like c[1][2]=5 to make an array of arrays c => [[5]].

当然，我可以通过拆分& 和 = ，但是其他情况如数组和数组数组。我想从POST请求queryString中获取 结构化 NSDictionary，并且如果已经存在，则不想重写轮。

Of course I can do it myself by splitting on the & and =, but what about other cases such as arrays and arrays of arrays. I want a structured NSDictionary from a POST request queryString and do not want to rewrite the wheel if this already exists.

有没有任何类/方法，通过苹果或第三方，将解析查询字符串到一个结构化的NSDictionary？

Are there any class/method, through Apple or 3rd party, that will parse a query string into a structured NSDictionary?

推荐答案

Google Toolbox for Mac 包含 GTMNSDictionaryURLArgumentsAdditions code> category NSDictionary 这可以做你想要的。

The Google Toolbox for Mac contains a GTMNSDictionaryURLArgumentsAdditions category on NSDictionary which may do what you want.

如果你可以控制查询字符串（在客户端），你可以发送一个编码plist，可以直接解码为 NSDictionary 。

If you have control over the query string (on the client side), you could send an encoded plist which can be decoded directly into an NSDictionary.
