go - Read multiple time a Reader -

-

i have 2 http handlers use same http.responsewriter , *http.request , read request body this:

func method1 (w http.responsewriter, r *http.request){     var postdata database.user     if err := json.newdecoder(r.body).decode(&postdata); err != nil {       //return error     } }  func method2 (w http.responsewriter, r *http.request){     var postdata database.user     //this read gives (of course) eof error     if err := json.newdecoder(r.body).decode(&postdata); err != nil {       //return error     } }

because of need keep these 2 methods separated, , both of them need read request body, best way (if it's possible) seek request body (which readcloser, not seeker?).

actually, miku, i've found out best solution using teereader, changing method1 in way

func method1 (w http.responsewriter, r *http.request){     b := bytes.newbuffer(make([]byte, 0))     reader := io.teereader(r.body, b)      var postdata mystruct     if err := json.newdecoder(reader).decode(&postdata); err != nil {         //return error     }      r.body = ioutil.nopcloser(b) }

asp.net - 'System.Web.HttpContext' does not contain a definition for 'GetOwinContext' Mystery -

i realize question might seem trivial some, it's these types of things find myself fighting quite bit , want make sense of despite seeming losing battle in .net (for me anyway). so, if following: using system.web; ... applicationuser user = system.web.httpcontext.getowincontext().getusermanager<applicationusermanager>().findbyid(system.web.httpcontext.user.identity.getuserid()); that produces error in title , red getowincontext() , error cannot resolve symbol 'getowincontext()' however, if following (remove system.web in front of httpcontext ), works expected (or @ least no errors): using system.web; ... applicationuser user = httpcontext.getowincontext().getusermanager<applicationusermanager>().findbyid(system.web.httpcontext.user.identity.getuserid()); however, if (same line that's working using system.web commented out): //using system.web; ... applicationuser user = httpcontext.getowincontext().getusermana...

mercurial graft feature, can it copy? -

-
there new feature in mercurial 3, called 'graft' (graft local). job of moving change-set different branch. is there way "copy" change-set branch? i interested in in moving stuff qa branch production branch, still need code reside in qa. want copy. found , have tried few things, maybe it'll become clear more tinkering , reading... does have better way of 'cherry picking' change-sets move cross branch (or trunk)??? graft copies changesets, doesn't move them. hg graft (emphasis mine): this command uses mercurial's merge logic copy individual changes other branches without merging branches in history graph. known 'backporting' or 'cherry-picking' . default, graft copy user, date, , description source changesets.
