groovy - Can't understand why Google Translate REST API returns HTTP 400 -


using camel route sending post request google translate api:

from("direct:start"). setheader(exchange.http_method, constant('post')). setheader('x-http-method-override', constant('get')). setbody(constant('q=hello')).                                                                                                                                                                                                            log(logginglevel.info, 'sourcingtool', '${body}'). to("https://www.googleapis.com/language/translate/v2?key=${api_key}&target=fr"). to('stream:out')

for reason getting http 400. seeing problem in request?

update 1 when i'm using curl , sending similar request, everyting works charm:

curl -xpost -h "x-http-method-override:get" --data "q=hello" "https://www.googleapis.com/language/translate/v2?key=my_api_key&target=fr"

the answer simple. needed explicitly set content_type:

from("direct:start"). setheader(exchange.http_method, constant('post')). setheader(exchange.content_type, constant('application/x-www-form-urlencoded')). // 1 did trick setheader('x-http-method-override', constant('get')). setbody(constant('q=hello')).                                                                                                                                                                                                            log(logginglevel.info, 'sourcingtool', '${body}'). to("https://www.googleapis.com/language/translate/v2?key=${api_key}&target=fr"). to('stream:out')

c++ - Correct method for redrawing a layered window -

i have window created ws_ex_layered window style. drawing onto memory bitmap using gdi+, , using updatelayeredwindow update graphical content of layered window. intend use window main window of application, require redraw frequently. seeing layered windows not receive wm_paint windows message [?] , need come appropriate method re-drawing window. optimisation not essential , it's nice have cake , eat too. therefore, in search of "correct" method use. here thoughts far: i guess it's idea render onto off-screen bitmap before bitblt ing or similar. 60 frames rendered per second should (more than?) enough (but how compare other applications' frame rates?). possible solutions: use settimer send wm_timer message on regular basis. useful because through specifying time-out value, can achieve desired frames per second, without requirement measure duration "frame" takes rendered. would cause input or other lags due frequency , speed of m...
