NSURLで取得出来るURL(URI)のパラメータ一覧

NSURLのどのメソッドでどの要素が取れるんだっけ？となりがちなのでメモしとく。

プログラム。

	NSURL *url = [NSURL URLWithString:@"http://user:password@www.example.com:8080/hoge/fuga/index.html?a=1&b=2#test"];
	NSLog(@"absoluteString : %@", [url absoluteString]);
	NSLog(@"absoluteURL : %@", [url absoluteURL]);
	NSLog(@"baseURL : %@", [url baseURL]);
	NSLog(@"fragment : %@", [url fragment]);
	NSLog(@"host : %@", [url host]);
	NSLog(@"lastPathComponent : %@", [url lastPathComponent]);
	NSLog(@"parameterString : %@", [url parameterString]);
	NSLog(@"password : %@", [url password]);
	NSLog(@"path : %@", [url path]);
	NSLog(@"pathComponents : %@", [url pathComponents]);
	NSLog(@"pathExtension : %@", [url pathExtension]);
	NSLog(@"port : %@", [url port]);
	NSLog(@"query : %@", [url query]);
	NSLog(@"relativePath : %@", [url relativePath]);
	NSLog(@"relativeString : %@", [url relativeString]);
	NSLog(@"resourceSpecifier : %@", [url resourceSpecifier]);
	NSLog(@"scheme : %@", [url scheme]);
	NSLog(@"standardizedURL : %@", [url standardizedURL]);
	NSLog(@"user : %@", [url user]);

Base URLを使用した場合のプログラム。

	NSURL *baseUrl = [NSURL URLWithString:@"http://user:password@www.example.com:8080"];
	NSURL *url = [NSURL URLWithString:@"hoge/fuga/index.html?a=1&b=2#test" relativeToURL:baseUrl];

いずれの場合も parameterString の結果が (null) なのが気になって調べた所、RFC 1808によると「object parameters」と呼ばれるものみたいです。

使用する時の形式はこんな感じ。

;type=a

以下の様に複数指定する事も可能です。

;hoge=1;fuga=2

ということでこんなプログラムで確認。

	NSURL *url = [NSURL URLWithString:@"http://www.example.com/index.html;xxx=333?a=1&b=2#test"];
	NSLog(@"parameterString : %@", [url parameterString]);

出力結果はこちら。ちゃんと xxx=333 の部分が取得出来ました。
