專案簡介： 基於 HTTP 協議實現一個多執行緒伺服器，客戶端通過瀏覽器傳送請求，伺服器接收並分析客戶端的請求方法和資源，從而執行相應的邏輯處理，最終將客戶請求的資源以 HTML 頁面的形式呈現，並能進行差錯處理。 專案思路： 首先實現兩個主機不同程序間的通訊，當伺服器收到請求後，要進行分析請求方法，當方法確定後應該拿到請求的資源，接下來要根據資源是否存在執行相應的邏輯處理。GET 方法：如果沒有引數，進入非 cgi 模式執行；否則，進入 cgi 模式執行；只要是 POST 方法就一定要支援 cgi：直接進入 cgi 模式執行。 專案特點： 1、支援客戶端/伺服器模式，客戶端能夠使用 GET、POST 方法請求資源； 2、簡單快速：客戶向伺服器請求服務時，只需傳送請求方法和路徑； 3、靈活：HTTP 允許傳輸任意型別的資料物件，正在傳輸的型別由 Content-Type 加以標記。
