TCP實現檔案傳輸

一直想著給之前的clouddisk專案加上乙個c/s架構的檔案傳輸模組，因為之前是nginx+fastcgi架構的b/s架構，自己又不會前段**，沒有辦法繼續增加新的功能塊。最近終於抽出時間開始寫專案了，已經選用tcp完成linux下的cs架構檔案上傳功能模組，這裡展示tcp檔案傳輸模組。

socket類裡僅僅封裝了tcp連線所需的api和一些必要變數。

TCP檔案傳輸（一）

最近在做網路抓包和檔案傳輸，今天遇到乙個奇怪的現象，自己查了半天也沒搞清楚，導致花了乙個下午時間就只實現了檔名和檔案長度的傳送，首先給出檔案傳輸的客戶端和伺服器端 一 客戶端 1 winsock com元件初始化和釋放 include stdafx.h ifndef winsock startup ...
