c++簡單實現http協議服務器和客戶端

C++ 簡單實現HTTP GET/POST 請求

HTTP(超文本傳輸協議)是一種客戶端與服務端的傳輸協議，最早用於瀏覽器和服務器之間的通信，後來因爲其使用靈活、方便等特點，廣泛用於客戶端與服務端的通信。文章將簡單介紹HTTP協議，同時以C++方式分別實現HTTP GET、POST 請求

HTTP 請求報文

HTTP請求報文的一般格式由4部分組成：請求行、請求頭部、空行、請求數據。如下圖所示：

1.jpg

請求行：包含3部分內容：請求方法，URL，協議版本。形式如：GET /?aaa=1 HTTP/1.1。請求方法有GET、POST、HEAD、PUT、DELETE、OPTIONS等。URL指請求服務端的地址，可以是相對地址或域名形式的絕對地址。協議版本主要有HTTP/1.1 HTTP/1.0 HTTP/0.9，後面兩種已很少使用了。

請求頭部：以key/value形式成對錶示頭部參數，以英文冒號分隔。key名稱的約定寫法爲Key，Key-Name，自定義key名稱一般以“X-”開頭。如php的聲明“X-Powered-By:PHP/5.5.4-1”

空行：用來標識請求頭部的數據已結束。

請求數據：可選項，這塊內容只在POST方式下使用，作爲POST的數據表示區域。使用這塊內容，要在請求頭部以Content-Length聲明請求數據長度，以Content-Type聲明請求數據類型。

HTTP POST請求

HTTP POST方式是把請求參數放到HTTP請求報文的請求數據中，爲了讓例子更容易看懂，僅保留HTTP Post關鍵參數，你還可以自定義一些參數，比如瀏覽器喜歡用的User-Agent，Accept，Connection等等

char *pHttpPost = "POST %s HTTP/1.1\r\n"
    "Host: %s:%d\r\n"
    "Content-Type: application/x-www-form-urlencoded\r\n"
    "Content-Length: %d\r\n\r\n"
    "%s";
 
char* addr = "http://localhost/post.php";
char* host = "127.0.0.1";
int port = 80;
char* msg = "aaa=1&bbb=2";
 
char strHttpPost[1024] = {0};
sprintf(strHttpPost, pHttpPost, addr, host, port, strlen(msg), msg);
 
//這裏忽略掉了socket連接代碼
 
send(sockClient, strHttpPost, strlen(strHttpPost), 0);

HTTP GET請求

HTTP GET方式是把請求參數放到HTTP請求報文的請求行URL中，所以請求行就是“GET /?aaa=1&bbb=2 HTTP/1.1\r\n”。URL最大長度通常瀏覽器取255，這和文件路徑最大長度有關。雖然HTTP允許更大長度，但不建議怎麼做，如果太長了，可以考慮換成POST方式

char *pHttpGet = "GET %s?%s HTTP/1.1\r\n"
    "Host: %s:%d\r\n\r\n";
 
char* addr = "http://localhost/get.php";
char* host = "127.0.0.1";
int post = 80;
char* msg = "aaa=1&bbb=2";
 
char strHttpGet[1024] = {0};
sprintf(strHttpGet, pHttpGet, addr, msg,  host, post);
 
//這裏忽略掉了socket連接代碼
 
send(sockClient, strHttpGet, strlen(strHttpGet), 0);
