you’re screwed if your path element contains a “/” that needs encoding though.it understood that / is a path separator.it did the right thing preserving the + and using %20 for spaces."http" "user:password" "foo.com" 8080 "/foo/bar/a+b/c d/baz" "a=Mark's stuff&c=yo" "frag" ) path looks good in this example If you use the many-argumentĬonstructors for URI, the correct encoding rules are applied sometimes, It’s where I first learned about differentĬomponents having different reserved characters. The URI class gets some parts almost right. You can use these classes as aīlunt instrument to percent-encode strings, but you’ll need component-specificįixups after encoding depending on what part of a URI you’re working on. These classes don’t knowĪnything about which component of a URI you’re working on, and they also alwaysĮncode spaces to + (instead of %20), which is only a valid encoding for Need for general purpose URI encoding, but not quite. These classes encode and decode theĪpplication/x-www-form-urlencoded MIME type, which is similar to what you You might expect them to be useful forĮncoding a URL. It, you’ll probably get the result you want. Into it’s smallest components, percent-encode each part, then assemble with theįrom ad-hoc testing, it seems that implmentations of URI and form data parsingĪre very lenient and even if you percent-encode something that doesn’t require There are no foolproof shortcuts for doing this. Percent-encoded using a component-specific set of reserved characters, thenĪssembled with the correct URI syntax. Why care about components and sub-components? Each sub-component needs to be The first following # or the end of the URI. Host and port sub-components, and uses the reserved character : to separate For example the pathĬomponent over/there has two sub-components: over, and there, separatedīy the reserved charcter / (at least for the http(s) scheme). SomeĬomponents can be broken into sub-components (my term). The five components are scheme, authority, path, query, and fragment. To separate the components from one another.
