I want to call a JSP with GET parameters within the GET parameter of a parent JSP. The URL for this would be http://server/getMap.jsp?lat=30&lon=-90&name=http://server/getName.jsp?lat1=30&lon1=-90
getName.jsp will return a string that goes in the name parameter of getMap.jsp.
I think the problem here is that &lon1=-90 at the end of the URL will be given to getMap.jsp instead of getName.jsp. Is there a way to distinguish which GET parameter goes to which URL?
One idea I had was to encode the second URL (e.g. = -> %3D and & -> %26) but that didn't work out well. My best idea so far is to allow only one parameter in the second URL, comma-delimited. So I'll have http://server/getMap.jsp?lat=30&lon=-90&name=http://server/getName.jsp?params=30,-90 and leave it up to getName.jsp to parse its variables. This way I leave the & alone.
NOTE - I know I can approach this problem from a completely different angle and avoid nested URLs altogether, but I still wonder (for the sake of knowledge!) if this is possible or if anyone has done it...
This has been done a lot, especially with ad serving technologies and URL redirects
But an encoded URL should just work fine. You need to completely encode it tho. A generator can be found here
So this:
http://server/getMap.jsp?lat=30&lon=-90&name=http://server/getName.jsp?lat1=30&lon1=-90
becomes this: http://server/getMap.jsp?lat=30&lon=-90&name=http%3A%2F%2Fserver%2FgetName.jsp%3Flat1%3D30%26lon1%3D-90
I am sure that jsp has a function for this. Look for "urlencode". Your JSP will see the contents of the GET-Variable "name" as the unencoded string: "http://server/getName.jsp?lat1=30&lon1=-90"

I came across an unusual URL structure on a site. It looked like this:
https://www.agilealliance.org/glossary/xp/#q=~(infinite~false~filters~(postType~(~'post~'aa_book~'aa_event_session~'aa_experience_report)~tags~(~'xp))~searchTerm~'~sort~false~sortDirection~'asc~page~1)
It seems the category, pagination and sort options of a widget on the page injects and reads through these values. Does this format for storing data in the URL have a name, or is this an esoteric format someone made?
What's the purpose of doing this over using regular GET params, or at least using a more conventional format after the fragment?
If you inspect the URL carefully, you'll see that the parameters you describe are placed after the fragment (#), meaning they're not sent to the server but used by the client instead.
In this case, the client (JavaScript) builds them into something like an ElasticSearch query that's then POSTed to the server, in order to update listing you see on your screen.
I have following string:
soqDi22c2_A-eY4ahWKJV6GAYgmuJBZ3poNNEixha1lOhXxxoucRuuzmcyDD_9ZYp_ECXRPbrBf6issNn23CUDJrh_A5L3Y5dHhB0o_U5Oq_j4rDCXOJ4Q==
It's a query parameter generated by form on a page. (This is done server-side in ASP.net) We are able to submit this form programatically and get the string we need (it just leads to a detail page of an object [realworld parcel/building, publicly accessible]) and redirect our user to it. However I would like to know, if there is a way to decrypt/deobfuscate this string to know what it contains and if we could possibly just generate these without going through the form (it's a multi step form).
The string also has some sort of expiration, so I sadly cannot provide a link to the result page, as it would stop working after like 10 minutes or so.
It feels a bit like it's base64, but after trying to run it through base64 -d, it says it's invalid.
It's likely base64 with + and / replaced with - and _ to make it more browser-friendly.
Though even if it's base64-encoded, it may just be a completely random key. You won't nessesarily be able to decode it to something readable.
Backbone.js maintains routing information in a URL after the hash mark, e.g.:
http://localhost:3000#page/hardware/table/?action=details&actionTargetId=5&actionTargetName=10.3.177.185&actionTarget=host
Even though the routing information is in the format ?p1=v1&p2=v2&p3=v3, this portion is not technically part of the url query string since it comes after the hash mark.
My question is if I add an actual query string to our app's urls like this:
http://localhost:3000?newparam=newvalue#page/hardware/table/?action=details&actionTargetId=5&actionTargetName=10.3.177.185&actionTarget=host
is there any possibility of the "newparam" url parameter interfering with the backbone portion?
the problem is your not actually creating a legit query string. your mixing your route with your parameters.
your example is formatted as:
domain ? param # route ? other params
as soon as a questionmark appears in a url everything after it is interpreted as a query string. (in this case) even your route.
personally i suggest using the html5 pushstate.
Backbone.history.start({pushState: true})
this will give you clean(er) urls
http://localhost:3000/page/hardware/table/?newparam=newvalue&action=details&actionTargetId=5&actionTargetName=10.3.177.185&actionTarget=host
that will help your routes to not interfere with your parameters.
This seems like the dumbest question ever, but I can't seem to figure it out. I have a page the needs to redirect to a complex route and I can't seem to generate the URL. Redirecting to a simple route is easy enough:
return $this->redirect($this->generateUrl('testnumber'));
However, I want to route to: testnumber/1/question/4. How can I accomplish this incredibly simple task? The only thing I have found in the documentation and Google allows me to add parameters and not just create a complex route. For example:
generateURL('testnumber', array('testid'=>1, 'question'=>4))
makes a URL of /testnumber?testid=1&question=4, which I do not want.
Edit: Yes, I already have the route created in a YML file. I simply cannot generate the URL to link to it.
return $this->redirect($this->generateUrl(???????????),true));
This is my route:
#Route("/testnumber/{testid}/question/{question}", name="testnumber")
The Symfony documentation only shows how to generate a URL to " testnumber/1", I need to generate "testnumber/1/question/4".
For
generateURL('testnumber', array('testid'=>1, 'question'=>4))
to work as you want, your route must look like (example using annotations)
#Route("/testnumber/{testid}/question/{question}", name="testnumber")
If you don't define "testid" & "question" parameters in your route, they'll be added to the query string (appended at the end of the URL as GET paramaters)
generated_route?test_id=X&question=X

I want to allow my users to "bulk export" an archive of selected resources, i.e., http://.../resource/1, resource/2, resource/4, ... ,
My thought was "render the HTML of each page to a string and use java.util.zip to create a multifile archive."
My problem then became "how to get the HTML of a page so that I can loop over them?"
I cannot figure out a way to get a JstlView to render to a String, nor can I see a way to set the ServletOutputStream to be a ZipOutputStream.
My last thought is to actually GET the HTML of each of the resources via HTTP. I imagine that will be easy enough to code, but it seems pretty byzantine. Is there a better way? (Perhaps something with RequestDispatcher.forward()? )
Use a SwallowingHttpServletResponse from DWR (or a PageResponseWrapper from Sitemesh) as a parameter to RequestDispatcher.include() and then get the output from that response object.
See my response (no pun intended) to this question.
