ulufalega
Na amata uma ina ua fautua mai se paaga ou te faia se tamai auaunaga i luga o le initaneti. Sa tatau ona pei o le Tinder, ae mo tagata IT. O le faʻatinoga e matua faigofie lava, e te lesitala, faʻatumu se talaaga ma agai i luga i le autu autu, o le sailia lea o se tagata e talanoa i ai ma faʻalauteleina au fesoʻotaʻiga ma faia ni masani fou.
O lea e tatau ona ou solomuli ma faamatala sina mea e uiga ia te aʻu lava, ina ia sili atu ona manino i le lumanaʻi pe aisea na ou faia ai ia laasaga i le atinaʻe.
I le taimi nei o loʻo ou umia le tulaga o Faʻataʻitaʻi Faʻatekonolosi i totonu o se tasi taʻaloga taʻaloga, o loʻu poto masani i le C # na fausia i luga o le tusiaina o tusitusiga ma mea faʻaoga mo le Lotogatasi ma, faʻaopoopo i lenei, fatuina plugins mo galuega maualalo ma masini Android. Ou te lei alu lava i tala atu o lenei lalolagi itiiti, ona tulai mai ai lea o se avanoa faapena.
Vaega 1. Fa'atusa fa'atusa
Ina ua uma ona ou filifili pe o le a le tulaga o lenei auaunaga, na amata ona ou suʻeina ni filifiliga mo le faʻatinoga. O le mea pito sili ona faigofie o le sailia lea o se ituaiga o fofo ua saunia, lea, e pei o se lulu i luga o le kelope, e mafai ona tosoina a tatou masini ma mafai ona faʻaalia le mea atoa i faʻasalaga lautele.
Ae e le manaia lenei mea, ou te leʻi vaʻaia se luʻitau poʻo se lagona i totonu, ma o lea na amata ai ona ou suʻesuʻeina tekinolosi i luga o le initaneti ma auala e fegalegaleai ai ma i latou.
Na amata ona ou suʻesuʻe e ala i le tilotilo i tala ma faʻamaumauga ile C # .Net. O iinei na ou maua ai auala eseese e faʻamaeʻa ai le galuega. E tele auala mo le fegalegaleai ma le fesoʻotaʻiga, mai fofo atoatoa e pei o le ASP.Net poʻo le Azure auaunaga, e faʻatonu ai fegalegaleaiga ma TcpHttp fesoʻotaʻiga.
O le faia o laʻu taumafaiga muamua i le ASP, na vave ona ou teena; i loʻu manatu, o se filifiliga faigata tele lea mo la matou auaunaga. Matou te le faʻaaogaina e oʻo lava i le tasi vaetolu o lenei tulaga gafatia, o lea na ou faʻaauau ai laʻu sailiga. O le filifiliga sa i le va o le TCP ma le Http client-server. O iinei, i luga o Habré, na ou maua ai se tala e uiga i , I le aoina ma faʻataʻitaʻiina, na ou filifili ai e taulaʻi faʻapitoa i fegalegaleaiga ma fesoʻotaʻiga TCP, mo nisi mafuaʻaga na ou manatu ai o le a le faʻatagaina aʻu e le http e faia se fofo faʻasolosolo.
O le vaega muamua o le 'au'aunaga na aofia ai le fa'aogaina o feso'ota'iga, fa'aulufaleina le anotusi o le itulau i luga ole laiga, ma aofia ai se fa'amaumauga o tagata fa'aoga. Ma i le amataga, na ou filifili e fausia galuega mo le galue i luga o le upega tafaʻilagi, ina ia mafai ai ona ou faʻaopoopoina le faagasologa o le talosaga ile Android ma iOS.

Ma o mea uma e galue e pei o le uati, faʻatagaina ma le resitalaina o galuega, o le galuega maualalo mo le mauaina o le tautua ua uma ona i ai ma ua oʻo mai le taimi e tusi ai se talosaga ma nonoa le mea atoa faʻatasi ma galuega autu o loʻo faia ai mea uma.Mataupu 4. Lafoai ese o le uila
Ina ia faʻaitiitia le tau o tagata faigaluega o le tusiaina o talosaga e lua mo faʻavae e lua, na ou filifili ai e fai se faʻasalalauga i luga ole Xamarin.Forms. Toe, faʻafetai i le mea moni o loʻo i totonu C #. I le faia o se suʻega suʻega e naʻo le lafoina o faʻamatalaga i le 'auʻaunaga, na ou maua ai se mea manaia. Mo se talosaga mai se masini, mo le malie, na ou faʻatinoina i luga o le HttpClient ma auina atu i le server HttpRequestMessage, lea o loʻo i ai faʻamatalaga mai le pepa faʻatagaina i le json format. E aunoa ma le faʻamoemoeina o se mea, na ou tatalaina le log server ma vaʻai ai iina se talosaga mai le masini ma faʻamatalaga uma. O se fa'aletonu la'ititi, fa'alauiloa mea uma na faia i le 3 vaiaso talu ai i se afiafi fa'aletonu. Ina ia siaki le saʻo o faʻamatalaga na lafoina, na ou faʻapipiʻiina se suʻega suʻega ile HttpListner. I le mauaina o se isi talosaga ua uma ona i luga, na ou vavae ese i ni nai laina o code ma maua se KeyValuePair o faʻamaumauga mai le fomu. O le fa'avasegaina o le fesili na fa'aitiitia i laina e lua.
Na amata ona ou faʻataʻitaʻiina atili, e leʻi taʻua muamua, ae i luga o le server muamua na ou faʻatinoina foi se talatalanoaga na fausia i luga o websockets. Na aoga tele, ae o le mataupu faavae o fegalegaleaiga e ala i le Tcp na faʻavaivaia; tele naua galuega e le manaʻomia e tatau ona faia ina ia mafai ai ona fausia lelei le fegalegaleaiga a tagata faʻaoga e toʻalua ma se faʻamaumauga o fesoʻotaʻiga. E aofia ai le faʻavasegaina o se talosaga e fesuiaʻi le fesoʻotaʻiga ma le aoina o se tali e faʻaaoga ai le protocol RFC 6455. O le mea lea, i le suʻega suʻega, na ou filifili ai e fatuina se fesoʻotaʻiga websocket faigofie. Na'o le fiafia.
Fesootai i talatalanoaga
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(); } } } } }Ma sa aoga. O le server lava ia na faʻapipiʻiina le fesoʻotaʻiga ma faʻatupuina se ki tali. Ou te leʻi manaʻomia foʻi ona faʻapipiʻi ese le resitalaina o le server e ala i le SSL; ua lava le faʻaogaina o le tusi faʻamaonia i luga o le taulaga manaʻomia.
I luga o le itu o le masini ma le itu o le upega tafaʻilagi, e lua tagata faʻatau na fefaʻasoaaʻi feʻau, o nei mea uma na faʻamauina. Leai ni parser tetele e fa'agesegese ai le 'au'aunaga, e leai se mea na mana'omia. Ua fa'aitiitia le taimi tali mai le 200ms i le 40-30ms. Ma na ou sau i le filifiliga sa'o e tasi.
Tu'u ese le fa'atinoga o lo'o iai nei ile Tcp ma toe tusi mea uma ile Http. O le taimi nei o le poloketi o loʻo i totonu o le toe faʻatulagaina o tulaga, ae e tusa ai ma mataupu faavae eseese o fegalegaleaiga. O le faʻaogaina o masini ma le 'upega tafaʻilagi o loʻo faʻamaopoopoina ma faʻapipiʻiina ma e iai se manatu masani, ma na o le pau lava le eseesega e le manaʻomia le fausiaina o itulau HTML mo masini.
iʻuga
"Afai e te le iloa le ala, aua e te alu i totonu o le vai" Ou te manatu aʻo leʻi amataina galuega, e tatau ona sili atu ona manino aʻu sini ma faʻamoemoega, faʻapea foʻi ma le suʻesuʻeina o tekinolosi talafeagai ma metotia mo lo latou faʻatinoina i luga o tagata eseese. Ua lata ina mae'a le poloketi, ae masalo o le a ou toe sau e talanoa pe na faapefea ona ou toe faasaoina nisi mea. E tele mea na ou aʻoaʻoina i le faagasologa o le atinaʻeina, ae e tele atu mea e tatau ona aʻoaʻoina i le lumanaʻi. Afai na e faitau i lenei mamao, faafetai mo le faia.
