Subject [jira] [Commented] (HTTPCLIENT-1240) Empty HttpParams for cacheable requests
Date Thu, 04 Oct 2012 16:09:47 GMT

    [ https://issues.apache.org/jira/browse/HTTPCLIENT-1240?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13469472#comment-13469472
] 

Jon Moore commented on HTTPCLIENT-1240:
---------------------------------------

Hmm. Unfortunately, we can't take a patch that breaks the unit tests. Probably we are running
up against technical debt here, where the rest of httpclient uses Mockito (where it has useful
defaults for expect/verify behavior that isn't specified) but the caching module uses EasyMock.
I'll open an improvement ticket to do that work, then we can make this issue dependent on
that one and leave it open. I'm not sure that I have time anytime soon to get to that change,
though.

> With DefaultHttpClient, HttpResponse.getParams() returns a ClientParamsStack with all
the parameters previously set at HttpClient or HttpRequest level.
> With CachingHttpClient it returns an empty BasicHttpParams when a response is cached.
> This feature can be very usefull when you are doing complex processing with Interceptors
for example. It is described in HttpClient documentation:
> http://hc.apache.org/httpcomponents-client-ga/tutorial/html/fundamentals.html#d5e299
> http://hc.apache.org/httpcomponents-client-ga/httpclient/apidocs/org/apache/http/impl/client/ClientParamsStack.html
> CachingHttpClient should not break this feature.
> Here is some sample code:
> 	// Client and Request scoped params with DefaultHttpClient
> 	DefaultHttpClient httpClient = new DefaultHttpClient();
> 	httpClient.getParams().setParameter("testClientParam", "testClientParam");
> 	HttpGet httpGet = new HttpGet("http://www.google.fr/images/srpr/logo3w.png");
> 	httpGet.getParams().setParameter("testRequestParam", "testRequestParam");
> 	HttpResponse response = httpClient.execute(httpGet);
> 	EntityUtils.consumeQuietly(response.getEntity());
> 	System.out.println(response.getParams().getParameter("testClientParam"));
> 	System.out.println(response.getParams().getParameter("testRequestParam"));
> 	// Same test with CachingHttpClient
> 	httpClient = new DefaultHttpClient();
> 	CachingHttpClient cachingHttpClient = new CachingHttpClient(httpClient);
> 	cachingHttpClient.getParams().setParameter("testClientParam", "testClientParam");
> 	httpGet = new HttpGet("http://www.google.fr/images/srpr/logo3w.png");
> 	httpGet.getParams().setParameter("testRequestParam", "testRequestParam");
> 	response = cachingHttpClient.execute(httpGet);
> 	EntityUtils.consumeQuietly(response.getEntity());
> 	System.out.println(response.getParams().getParameter("testClientParam"));
> 	System.out.println(response.getParams().getParameter("testRequestParam"));
> If you agree I can provide a patch and unit tests
