ID卡網(wǎng)絡(luò)讀卡器TCP協(xié)議QT小程序開發(fā)。

TCP（傳輸控制協(xié)議，Transmission Control Protocol）是互聯(lián)網(wǎng)中最核心、最基本的協(xié)議之一。以下是對TCP協(xié)議的詳細(xì)介紹：

一、基本概念
TCP是一種面向連接的、可靠的、基于字節(jié)流的傳輸層通信協(xié)議。它工作在OSI模型的第四層，即傳輸層，為用戶提供可靠的、有序的和無差錯(cuò)的數(shù)據(jù)傳輸服務(wù)。TCP協(xié)議與UDP協(xié)議是傳輸層的兩大主要協(xié)議，但兩者在設(shè)計(jì)上有明顯的不同：TCP提供的是可靠的數(shù)據(jù)傳輸服務(wù)，而UDP則更注重傳輸?shù)乃俣群托省?/p>

二、技術(shù)特點(diǎn)
1.面向連接：TCP在傳輸數(shù)據(jù)之前，必須先建立連接，確保數(shù)據(jù)的傳輸路徑是可靠的。連接建立后，TCP會維護(hù)一個(gè)連接狀態(tài)，包括序列號、窗口大小等信息，用于保證數(shù)據(jù)傳輸?shù)挠行蛐院涂煽啃浴?br /> 2.可靠傳輸：TCP通過確認(rèn)重傳機(jī)制、滑動窗口機(jī)制、超時(shí)重傳機(jī)制等方式，確保數(shù)據(jù)在傳輸過程中不會丟失、不會重復(fù)、不會亂序。具體來說，TCP會給每個(gè)報(bào)文段分配一個(gè)序列號，接收方根據(jù)序列號確認(rèn)數(shù)據(jù)的順序和完整性。如果接收方發(fā)現(xiàn)數(shù)據(jù)丟失或亂序，會要求發(fā)送方重傳。
3.字節(jié)流傳輸：TCP將應(yīng)用層發(fā)送的數(shù)據(jù)劃分成以字節(jié)為單位的報(bào)文段，并進(jìn)行序列號標(biāo)記。這種方式能夠確保數(shù)據(jù)在傳輸過程中不會被拆分或丟失，從而保證數(shù)據(jù)的完整性。
4.全雙工通信：TCP允許雙方在任何時(shí)候都能發(fā)送數(shù)據(jù)，為此TCP連接的兩端都設(shè)有發(fā)送緩存和接收緩存，用來臨時(shí)存放雙向通信的數(shù)據(jù)。
三、工作原理
1.連接建立：TCP連接建立采用三次握手過程。首先，客戶端向服務(wù)器發(fā)送一個(gè)SYN報(bào)文段，請求建立連接。服務(wù)器收到后，回復(fù)一個(gè)SYN-ACK報(bào)文段，表示同意建立連接并確認(rèn)客戶端的SYN報(bào)文段。最后，客戶端再發(fā)送一個(gè)ACK報(bào)文段，確認(rèn)服務(wù)器的SYN-ACK報(bào)文段。至此，TCP連接建立完成。
2.數(shù)據(jù)傳輸：在連接建立后，雙方可以開始傳輸數(shù)據(jù)。TCP會將應(yīng)用層發(fā)送的數(shù)據(jù)劃分成報(bào)文段，并添加TCP頭部信息（包括序列號、窗口大小等），然后交給IP層進(jìn)行傳輸。接收方收到報(bào)文段后，會進(jìn)行校驗(yàn)和檢查、序列號確認(rèn)等操作，確保數(shù)據(jù)的完整性和順序性。如果發(fā)現(xiàn)問題，會要求發(fā)送方重傳。
3.連接終止：TCP連接終止采用四次揮手過程。首先，一方發(fā)送一個(gè)FIN報(bào)文段，表示要關(guān)閉連接。另一方收到后，回復(fù)一個(gè)ACK報(bào)文段，表示同意關(guān)閉連接但還有數(shù)據(jù)要發(fā)送。當(dāng)所有數(shù)據(jù)發(fā)送完畢后，另一方再發(fā)送一個(gè)FIN報(bào)文段，表示關(guān)閉連接。最后，接收方回復(fù)一個(gè)ACK報(bào)文段，確認(rèn)連接關(guān)閉。至此，TCP連接終止完成。
四、應(yīng)用場景
TCP協(xié)議廣泛應(yīng)用于需要可靠傳輸?shù)膱龊?，如HTTP、FTP等協(xié)議都基于TCP協(xié)議進(jìn)行數(shù)據(jù)傳輸。此外，TCP還用于數(shù)據(jù)庫連接、遠(yuǎn)程登錄等需要穩(wěn)定連接的場合。

綜上所述，TCP協(xié)議是一種高效、穩(wěn)定且可靠的傳輸層協(xié)議，它通過多種機(jī)制確保數(shù)據(jù)的可靠傳輸和有序性。在互聯(lián)網(wǎng)傳輸中，TCP協(xié)議發(fā)揮著重要作用。
