Class Method Details

.decode_www_form_component(str, _enc = nil) ⇒ Object

CRuby’s URI.decode_www_form_component / encode_www_form_component are used by Rack::Utils#unescape / Rack::Utils#escape. Opal’s ‘uri` stdlib omits them. Back them with CGI so that Rack’s query-string parser works for any request with a body / query (Sinatra’s ‘request.body.read` path eventually walks through this code).

IMPORTANT (Opal): CGI.unescape maps to JS decodeURI, which does NOT decode ‘%2F` (`/`). RFC 3986 decodeURI reserves those escapes; Rack form bodies need decodeURIComponent semantics (same as CGI.unescapeURIComponent). Without this, HTML like `</h1>` survives as literal `<%2Fh1>` in params.

.HTTP_class_for(scheme) ⇒ Object

Net::HTTP.get(URI(‘https://…’)) is the canonical entry point in CRuby Ruby code. CRuby resolves ‘URI(’…‘)` via Kernel#URI, which is defined in `uri/common.rb` as `URI.parse(arg)`. Opal’s stdlib omits that; install it here so vendored gems (and our Net::HTTP shim) can use the idiomatic short form.
