ios - NSURLComponents 获取百分比编码

根据NSURLComponents的文档:

If you set the unencoded property, you can then obtain the encoded equivalent by reading the encoded property value and vice versa.

我试图获取查询的百分比编码版本和 url 的路径，但我错过了一些东西:

NSURL * url = [NSURL URLWithString"http://google.com"];

NSURLComponents * components = [[NSURLComponents alloc] initWithURL:url resolvingAgainstBaseURL:YES];
components.query = @"oauth_callback=http://google.com";

NSLog(@"Encoded: %@", [components URL]); 
//-> Encoded: http://google.com?oauth_callback=http://google.com
//Does not encode "/" or ":"

我在哪里失败了？

我认为NSURLComponent 的行为是对的。 来自 Wikipedia :

In the "query" component of a URI (the part after a ? character), for example, "/" is still considered a reserved character but it normally has no reserved purpose, unless a particular URI scheme says otherwise. The character does not need to be percent-encoded when it has no reserved purpose.
