Ua hoʻomaka ia i ka manawa i manaʻo ai kekahi hoa hana e hana wau i kahi lawelawe pūnaewele liʻiliʻi. Ua manaʻo ʻia e like me Tinder, akā no ka lehulehu IT. He mea maʻalahi loa ka hana, hoʻopaʻa inoa ʻoe, hoʻopiha i kahi ʻaoʻao a neʻe i ke kumu nui, ʻo ia ka ʻimi ʻana i kahi kanaka e kamaʻilio ai a hoʻonui i kāu mau pilina a me nā kamaʻāina hou.
Eia ka'u e ho'i hope ai a e hai iki aku no'u iho, i maopopo ia'u ma keia mua aku ke kumu o ko'u hana ana pela i ka ulu ana.
I kēia manawa ke paʻa nei au i ke kūlana ʻo Technical Artist i hoʻokahi studio pāʻani, ua kūkulu ʻia koʻu ʻike papahana ma C # ma ke kākau ʻana i nā palapala a me nā pono hana no Unity a, ma kahi o kēia, e hana ana i nā plugins no ka hana haʻahaʻa me nā polokalamu Android. ʻAʻole wau i hele ma waho o kēia ao liʻiliʻi, a laila ua ala mai kahi manawa kūpono.
Mahele 1. Ka hoʻopololei ʻana i ka pahu
Ma hope o ka hoʻoholo ʻana i ke ʻano o kēia lawelawe, hoʻomaka wau e ʻimi i nā koho no ka hoʻokō. ʻO ka mea maʻalahi ka loaʻa ʻana o kahi ʻano hoʻonā i mākaukau, kahi e like me ka pueo ma ka honua, hiki ke huki ʻia kā mākou mechanics a hiki ke hōʻike ʻia nā mea āpau i ka hoʻopaʻapaʻa lehulehu.
Akā ʻaʻole hoihoi kēia, ʻaʻole wau i ʻike i kahi paʻakikī a i ʻole ka manaʻo i loko, a no laila ua hoʻomaka wau e aʻo i nā ʻenehana pūnaewele a me nā ʻano o ka launa pū ʻana me lākou.
Ua hoʻomaka wau e aʻo ma ka nānā ʻana i nā ʻatikala a me nā palapala ma C # .Net. Maʻaneʻi ua loaʻa iaʻu nā ala like ʻole e hoʻopau ai i ka hana. Nui nā hana no ka launa pū ʻana me ka pūnaewele, mai nā hoʻonā piha piha e like me ASP.Net a i ʻole nā lawelawe Azure, e kuhikuhi i ka pilina me nā pilina TcpHttp.
Ma hope o kaʻu hoʻāʻo mua ʻana me ASP, ua hōʻole koke wau; i koʻu manaʻo, he hoʻoholo paʻakikī loa kēia no kā mākou lawelawe. ʻAʻole mākou e hoʻohana i ka hapakolu o nā mana o kēia kahua, no laila ua hoʻomau wau i kaʻu ʻimi. Aia ke koho ma waena o TCP a me Http client-server. Eia, ma Habré, ua ʻike au i kahi ʻatikala e pili ana , i ka hōʻiliʻili ʻana a hoʻāʻo ʻia, ua hoʻoholo wau e kālele pono i ka pilina me nā pilina TCP, no kekahi kumu ua manaʻo wau ʻaʻole e ʻae ʻo http iaʻu e hana i kahi hopena cross-platform.
ʻO ka ʻaoʻao mua o ke kikowaena ua hoʻopili ʻia ka hoʻopili pili, lawelawe ʻia nā ʻike palapala pūnaewele static, a me kahi waihona mea hoʻohana. A i ka hoʻomaka ʻana, ua hoʻoholo wau e kūkulu i nā hana no ka hana ʻana me ka pūnaewele, i hiki iaʻu ke hoʻohui i ka hoʻoili ʻana o ka noi ma Android a me iOS.

A hana nā mea a pau e like me ka clockwork, ka ʻae a me ka hana hoʻopaʻa inoa, ʻo ka hana liʻiliʻi loa no ke komo ʻana i ka lawelawe aia i laila a ua hiki mai ka manawa e kākau ai i kahi noi a hoʻopaʻa i nā mea āpau me nā hana nui e hana ʻia ai nā mea āpau.Mokuna 4. Kiola i ke kaʻa
No ka ho'ēmiʻana i nā koina hana no ke kākauʻana iʻelua mau noi no nā papahanaʻelua, ua hoʻoholo wau e hana i kahi cross-platform ma Xamarin.Forms. Eia hou, mahalo i ka mea aia ma C #. Ma hope o ka hana ʻana i kahi noi hoʻāʻo e hoʻouna wale i ka ʻikepili i ke kikowaena, ua loaʻa iaʻu kahi mea hoihoi. No kahi noi mai kahi mea hana, no ka leʻaleʻa, ua hoʻokō au iā ia ma HttpClient a hoʻouna iā ia i ka server HttpRequestMessage, aia nā ʻikepili mai ka palapala ʻae i ka format json. Me ka manaʻo ʻole i kekahi mea, ua wehe au i ka log server a ʻike wau i kahi noi mai ka hāmeʻa me nā ʻikepili āpau. ʻO kahi stupor liʻiliʻi, ʻike i nā mea a pau i hana ʻia i nā pule he 3 i hala iho nei i ke ahiahi ʻoluʻolu. No ka nānā ʻana i ka pololei o ka ʻikepili i hoʻouna ʻia, ua hōʻuluʻulu au i kahi kikowaena hoʻāʻo ma HttpListner. Ma hope o ka loaʻa ʻana o kahi noi ʻē aʻe ma luna, ua wehe au iā ia ma nā laina ʻelua o ke code a loaʻa iaʻu kahi KeyValuePair o ka ʻikepili mai ka palapala. Ua hōʻemi ʻia ka ʻimi ʻana i ʻelua laina.
Ua hoʻomaka wau e hoʻāʻo hou, ʻaʻole ia i haʻi ʻia ma mua, akā ma ka server mua ua hoʻokō wau i kahi kamaʻilio i kūkulu ʻia ma nā websockets. Ua hana maikaʻi loa ia, akā ʻo ke kumu o ka launa pū ʻana ma o Tcp he mea kaumaha; nui nā hana pono ʻole i hana ʻia i mea e kūkulu pono ai i ka launa pū ʻana o nā mea hoʻohana ʻelua me kahi log pili. Hoʻopili kēia i kahi noi e hoʻololi i ka pilina a hōʻiliʻili i kahi pane me ka hoʻohana ʻana i ka protocol RFC 6455. No laila, i ka server hoʻāʻo, ua hoʻoholo wau e hana i kahi pilina websocket maʻalahi. No ka leʻaleʻa wale.
Hoʻohui i ke kamaʻilio
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(); } } } } }A ua hana. Na ke kikowaena ponoi i hoʻonohonoho i ka pilina a hana i kahi kī pane. ʻAʻole pono wau e hoʻonohonoho kaʻawale i ka hoʻopaʻa inoa ʻana o ka server ma o SSL; ua lawa ka loaʻa ʻana o ka ʻōnaehana i kahi palapala i kau ʻia ma ke awa i koi ʻia.
Ma ka ʻaoʻao ʻaoʻao a ma ka ʻaoʻao pūnaewele, ua hoʻololi nā mea kūʻai aku ʻelua i nā leka, ua hoʻopaʻa ʻia kēia mau mea āpau. ʻAʻohe parser nui e hoʻolōʻihi i ke kikowaena, ʻaʻohe o kēia i koi ʻia. Ua emi ka manawa pane mai 200ms a i 40-30ms. A hiki iaʻu i ka hoʻoholo kūpono wale nō.
E kiola i ka hoʻokō kikowaena o kēia manawa ma Tcp a kākau hou i nā mea āpau ma lalo o Http. I kēia manawa aia ka papahana i ka hoʻolālā hou ʻana, akā e like me nā loina like ʻole o ka pilina. Hoʻonohonoho ʻia ka hana o nā mea hana a me ka pūnaewele a hoʻopau ʻia a loaʻa kahi manaʻo maʻamau, ʻo ka ʻokoʻa wale nō ʻaʻole pono e hana i nā ʻaoʻao HTML no nā polokalamu.

"Inā ʻaʻole ʻoe ʻike i ke ala, mai hele i ka wai" Manaʻo wau ma mua o ka hoʻomaka ʻana i ka hana, pono iaʻu e wehewehe i nā pahuhopu a me nā pahuhopu, a me ka hoʻopaʻa ʻana i ka noiʻi ʻana i nā ʻenehana pono a me nā ʻano hana no kā lākou hoʻokō ʻana i nā mea kūʻai aku. Ua kokoke e hoʻopau ka papahana, akā e hoʻi paha wau e kamaʻilio e pili ana i kaʻu hoʻopakele hou ʻana i kekahi mau mea. Ua aʻo nui au i ka wā o ka hoʻomohala ʻana, akā ʻoi aku ka nui o nā mea e aʻo ai i ka wā e hiki mai ana. Inā ua heluhelu ʻoe i kēia mamao, mahalo no ka hana ʻana pēlā.
