java - Get request parameter with Play Framework? -

i learning play framework , understand can map request such /manager/user as:

/manage/:user controllers.application.some(user:string)

how map request /play/video?video_id=1sh1?

you have @ to the lowest degree 2 possibilities, let's phone call them approach1 , approach2.

in first approach can declare routes param default value. 0 candidate, easiest build status on top of it. it's typesafe, , pre-validates itself. recommend solution @ beginning. second approach reads params straight request string need parse integer , additionally validate if required.

routes:

get /approach1 controllers.application.approach1(video_id: int ?=0) /approach2 controllers.application.approach2

actions:

public static result approach1(int video_id) { if (video_id == 0) homecoming badrequest("wrong video id"); homecoming ok("1: display video no. " + video_id); } public static result approach2() { int video_id = 0; if (form().bindfromrequest().get("video_id") != null) { seek { video_id = integer.parseint(form().bindfromrequest().get("video_id")); } grab (exception e) { logger.error("int not parsed..."); } } if (video_id == 0) homecoming badrequest("wrong video id"); homecoming ok("2: display video no. " + video_id); }

ps: lol realized want utilize string identifier... anyway both approaches similar :)

Accessing MATLAB's unicode strings from C -

Accessing MATLAB's unicode strings from C - how can access underlying unicode info of matlab strings through matlab engine or mex c interfaces? here's example. let's set unicode characters in utf-8 encoded file test.txt, read as fid=fopen('test.txt','r','l','utf-8'); s=fscanf(fid, '%s') in matlab. now if first feature('defaultcharacterset', 'utf-8') , c engevalstring(ep, "s") , output text file utf-8. proves matlab stores unicode internally. if mxarraytostring(enggetvariable(ep, "s")) , unicode2native(s, 'latin-1') give me in matlab: non-latin-1 characters replaced character code 26. need getting access underlying unicode info c string in unicode format (utf-8, utf-16, etc.), , preserving non-latin-1 characters. is possible? my platform os x, matlab r2012b. addendum: documentation explicitly states "[mxarraytostring()] supports multibyte encoded characters...
