--------------------------------
Assignee: Jesse Ramos
> URISyntaxException when using "[" brackets in query string
> ----------------------------------------------------------
>
> Key: WINK-289
> URL: https://issues.apache.org/jira/browse/WINK-289
> Project: Wink
> Issue Type: Bug
> Components: Common
> Affects Versions: 1.1
> Environment: Java 5, Spring, Rest Client to access ATOM based Rest Services
> Reporter: Ingo Marahrens
> Assignee: Jesse Ramos
>
> I am using Wink to query/read several backend services using the Atom Protocol.
> One of those produces farely ugly URLs with "[" and "]" within the URL strings.
> When reading from a feed these URLs are already escaped like this http://myserver/dm/atom/library/%5B@Pgistest/@RMain.nsf%5D/feed .
> This way I can use them directly to read the next feed:
> URI uri = URI.create(uriString);
> new RestClient().resource(uri);
> At this point everything is fine, but as it continues an exception is thrown
> java.lang.IllegalArgumentException: schemeSpecificPart is invalid

> This looks like it is out of the public UriBuilder schemeSpecificPart(String ssp) throws IllegalArgumentException {...}
> but as I investigated further the "ssp" String now is "//myserver/dm/atom/library/[@Pgistest/@RMain.nsf]/feed"
> which means that the brackts ("[" and "]") are not escaped any more.
> The call comes from
> public UriBuilder uri(URI uri) throws IllegalArgumentException {
> ....
> if (uri.getSchemeSpecificPart() != null) {
> logger.debug("Constructing schemeSpecificPart");
> schemeSpecificPart(uri.getSchemeSpecificPart());
> }
> ....
> }
> The URI object I created at the beginning with the escape characters for the brackets now returns an unescaped URI string as result of uri.getSchemeSpecificPart().
> As this is used as a direct input for constructing a new URI object within this part of the UriBuilderImpl this leads to an IllegalArgumentException.
> public UriBuilder schemeSpecificPart(String ssp) throws IllegalArgumentException {
> ...
> URI uri = null;
> try {
> // uri templates will be automatically encoded
> uri = new URI(scheme, ssp, fragment);
> } catch (URISyntaxException e) {
> throw new IllegalArgumentException("schemeSpecificPart is invalid", e);
> }
> ....
> }
>
> This leads to the conclusion that URIs with special characters like brackets are currently not supported as (feed) urls.
> My current workaround is to use a proxy for the UriBuilderImpl class which catches the Exception and will than encode the part of the URI again before use.
> Enhancer e = new Enhancer();
> e.setSuperclass(originalBuilder.getClass());
> e.setCallback(new MethodInterceptor() {
> public Object intercept(Object obj, java.lang.reflect.Method method, Object[] args, MethodProxy proxy) throws Throwable {
> Object result;
> if ("schemeSpecificPart".equals(method.getName())) {
> try {
> result = proxy.invokeSuper(obj, args);
> } catch (IllegalArgumentException iae) {
> String ssp = (String) args[0];
> String encoded = UriUtils.encodeUri(ssp, "UTF-8");
> LOG.debug("in [{}], out [{}]", new Object[]{ssp, encoded });
> // set encoded value:
> result = proxy.invokeSuper(obj, new Object[]{encoded });
> }
> } else {
> // do normal execution
> result = proxy.invokeSuper(obj, args);
> }
> return result;
> }
> });
>
> As we are using the Spring framework I used the UriUtils from Spring to escape the URI string again.
> As this is just a workaround not a solution, I hope for a fix within Wink to handle this.
