Thank you Jens and Charles for the additional tips. So Apple provides three routines for getting the path component of a URL. They all give different answers.
• -[NSURL path]. Mangles it, per documentation. Not only does it strip the trailing slash, but it unescapes percent escapes. • CFURLCopyPath(). According to documentation, "This function does not resolve the URL against its base and replaces all percent escape sequences." Does that mean that it replaces percent escapes? My interpretation is that it *does*, but in testing I see that it it does *not*. It does not strip any leading slash. • CFURLCopyStrictPath(). Ditto the above, except that it strips the leading slash. Since the leading slash is part of the path according to RFC 3986, this means that the "Strict" method is not strict, and the non-strict method is strict. CONCLUSION: CFURLCopyPath() is the winner, and I sent Apple a "not helpful" on the CFURL documentation. TEST CODE: NSString* s = @"http://example.com/path/to/id%3D8528/"; ; NSLog(@" given: %@", s) ; NSURL* url = [NSURL URLWithString:s] ; NSString* cocoaPath = [url path] ; NSString* cfPath = [(NSString*)CFURLCopyPath((CFURLRef)url) autorelease] ; NSString* cfstrictPath = [(NSString*)CFURLCopyStrictPath((CFURLRef)url, NULL) autorelease] ; NSLog(@" cocoaPath: %@", cocoaPath) ; NSLog(@" cfPath: %@", cfPath) ; NSLog(@"cfstrictPath: %@", cfstrictPath) ; RESULTS: given: http://example.com/path/to/id%3D8528/ cocoaPath: /path/to/id=8528 cfPath: /path/to/id%3D8528/ cfstrictPath: path/to/id%3D8528/ _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
