Zonse zidayamba pomwe mnzanga adandiuza kuti ndipange kawebusayiti kakang'ono. Izo zimayenera kukhala zinazake ngati tinder, koma kwa IT hangout. Magwiridwe ake ndi osavuta, mumalembetsa, lembani mbiri ndikupita ku mfundo yayikulu, mwachitsanzo, kupeza wolumikizirana ndikukulitsa kulumikizana kwanu ndikupanga mabwenzi atsopano.
Pano ndiyenera kudodometsa ndikunena pang'ono za ine ndekha, kuti m'tsogolo zidziwike bwino chifukwa chake ndinatengera izi pa chitukuko.
Pakalipano ndili ndi udindo wa Technical Artist mu studio yamasewera, chidziwitso changa cha C # chinakhazikitsidwa polemba zolemba ndi zofunikira za Unity ndipo, kuwonjezera pa izi, kupanga mapulagini a ntchito yotsika ndi zipangizo za android. Kunja kwa dziko lino, sindinasankhebe mwayi woterowo.
Gawo 1. Mafelemu Prototyping
Nditasankha momwe ntchitoyi ingakhalire, ndinayamba kuyang'ana njira zomwe ndingagwiritsire ntchito. Njira yosavuta ndiyo kupeza njira yokonzekera, yomwe, ngati kadzidzi padziko lonse lapansi, mutha kukoka makina athu ndikuyala chinthu chonsecho kuti chitsutsidwe pagulu.
Koma izi sizosangalatsa, sindinawone zovuta ndi malingaliro mu izi, chifukwa chake ndidayamba kuphunzira ukadaulo wapaintaneti ndi njira zolumikizirana nawo.
Phunziroli linayamba ndikuwona zolemba ndi zolemba pa C # .Net. Apa ndinapeza njira zosiyanasiyana zokwaniritsira ntchitoyi. Pali njira zambiri zolumikizirana ndi netiweki, kuchokera kumayankho athunthu monga ASP.Net kapena ntchito za Azure, kuwongolera kulumikizana ndi kulumikizana kwa TcpHttp.
Nditayesa koyamba ndi ASP, ndidazimitsa nthawi yomweyo, m'malingaliro mwanga chinali chisankho chovuta kwambiri pantchito yathu. Sitidzagwiritsa ntchito ngakhale gawo limodzi mwa magawo atatu a kuthekera kwa nsanjayi, kotero ndidapitiliza kufufuza kwanga. Kusankha kudakhala pakati pa TCP ndi Http kasitomala-server. Pano, pa HabrΓ©, ndinapeza nkhani yokhudza , nditasonkhanitsa ndikuyesa zomwe, ndinaganiza zoganizira za kuyanjana ndi kugwirizana kwa TCP, pazifukwa zina ndinaganiza kuti http sangandilole kuti ndipange njira yothetsera vutoli.
Mtundu woyamba wa seva umaphatikizapo kulumikiza zolumikizira, kutumiza zomwe zili patsamba lawebusayiti, komanso kuphatikizira nkhokwe ya ogwiritsa ntchito. Ndipo poyambira, ndidaganiza zopanga zogwirira ntchito ndi tsambalo, kuti pambuyo pake nditha kumangirira kukonzanso ntchito pa android ndi ios pano.

Nditalandira pempho lotsatira kale, ndidazipatula mumizere ingapo, ndidapeza data ya KeyValuePair kuchokera pafomu. Kukambirana kwa mafunso kwachepetsedwa kukhala mizere iwiri.
Ndinayamba kuyesanso, sizinatchulidwe kale, koma pa seva yapitayi ndidakhazikitsabe macheza opangidwa pa websockets. Zinagwira ntchito bwino, koma mfundo yolumikizirana kudzera pa Tcp inali yokhumudwitsa, zowonjezera zambiri zidayenera kupangidwa kuti apange kulumikizana kwabwino kwa ogwiritsa ntchito awiri ndikulemba makalata. Izi zikuphatikizapo kufotokoza pempho la kusintha kwa kugwirizana ndi kusonkhanitsa yankho pogwiritsa ntchito protocol ya RFC 6455. Choncho, mu seva yoyesera, ndinaganiza zopanga kugwirizana kosavuta kwa websocket. Chifukwa cha chidwi.
Kulumikizana ndi macheza
private static async void HandleWebsocket(HttpListenerContext context) { var socketContext = await context.AcceptWebSocketAsync(null); var socket = socketContext.WebSocket; Locker.EnterWriteLock(); try { Clients.Add(socket); } finally { Locker.ExitWriteLock(); } while (true) { var buffer = new ArraySegment<byte>(new byte[1024]); var result = await socket.ReceiveAsync(buffer, CancellationToken.None); var str = Encoding.Default.GetString(buffer); Console.WriteLine(str); for (int i = 0; i < Clients.Count; i++) { WebSocket client = Clients[i]; try { if (client.State == WebSocketState.Open) { await client.SendAsync(buffer, WebSocketMessageType.Text, true, CancellationToken.None); } } catch (ObjectDisposedException) { Locker.EnterWriteLock(); try { Clients.Remove(client); i--; } finally { Locker.ExitWriteLock(); } } } } }Ndipo zinathandiza. Seva yokhayo idakhazikitsa kulumikizana, idapanga kiyi yoyankha. Sindinayeneranso kukhazikitsa padera kulembetsa kwa seva kudzera pa ssl, ndizokwanira kuti dongosololi lili ndi satifiketi yoyikidwa padoko lofunikira.
Kumbali ya chipangizo ndi pa tsamba, makasitomala awiri adasinthanitsa mauthenga, zonsezi zidalowetsedwa. Palibe magawo akulu omwe akuchedwetsa seva, palibe chomwe chidafunikira. Nthawi yoyankha yachepetsedwa kuchokera ku 200ms mpaka 40-30ms. Ndipo ndinafika pa chisankho chokhacho choyenera.
Tayani kukhazikitsa kwa seva komweko pa Tcp ndikulembanso zonse pansi pa Http. Tsopano polojekitiyi ili pa siteji yokonzanso, koma molingana ndi mfundo zosiyana kwambiri za mgwirizano. Kugwiritsa ntchito zida ndi tsambalo zimalumikizidwa ndikusinthidwa ndipo zimakhala ndi lingaliro lofanana, ndi kusiyana kokha komwe zida sizifunikira kupanga masamba a html.
Pomaliza
"Popanda kudziwa ford, usalowetse mutu wako m'madzi" Ndikuganiza kuti, ndisanayambe ntchito, ndiyenera kufotokozera momveka bwino zolinga ndi zolinga, komanso ndikufufuza zaumisiri wofunikira ndi njira zogwiritsira ntchito makasitomala osiyanasiyana. Ntchitoyi yatsala pang'ono kutha, koma mwina ndibweranso kuti tidzakambirane m'mene ndinasokonezanso zinthu zina. Ndinaphunzira zambiri panthawi ya chitukuko, koma pali zambiri zoti ndiphunzire m'tsogolomu. Ngati mwawerenga mpaka pano, ndiye zikomo powerenga.
