1.http協議組成:
報文首部:狀態行(請求行) 請求首部字段 通用字段 其他信息
空行
報文主體
GET請求頭: GET /test.php?a=1 HTTP/1.1 Host: localhost Connection: keep-alive Cache-Control: max-age=0 Upgrade-Insecure-Requests: 1 User-Agent: Mozilla/5.0 (Windows NT 10.0; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/54.0.2840.99 Safari/537.36 Accept: text/html,application/xhtml+xml,application/xml;q=0.9,image/webp,*/*;q=0.8 Accept-Encoding: gzip, deflate, sdch, br Accept-Language: zh-CN,zh;q=0.8
POST請求頭: POST /test.php HTTP/1.1 Host: localhost Connection: keep-alive Content-Length: 42 Cache-Control: max-age=0 Origin: http://localhost Upgrade-Insecure-Requests: 1 User-Agent: Mozilla/5.0 (Windows NT 10.0; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/54.0.2840.99 Safari/537.36 Content-Type: application/x-www-form-urlencoded Accept: text/html,application/xhtml+xml,application/xml;q=0.9,image/webp,*/*;q=0.8 Referer: http://localhost/test.php Accept-Encoding: gzip, deflate, br Accept-Language: zh-CN,zh;q=0.8
2.在命令行下用telnet模擬發送get或post請求
1.cmd
2.telnet localhost 80
3.先同時按下"ctrl + ]" 用於回顯內容,再按下"回車鍵"
4.黏貼請求頭
GET請求頭: GET /test.php?a=1 HTTP/1.1 HOST:localhost POST請求頭: POST /test.php HTTP/1.1 HOST:localhost Content-Length:7 // 必須加上這個頭 Content-type:application/x-www-form-urlencoded name=ht // 在上面的請求頭黏貼完畢后,回車兩次,再輸入
// get請求頭黏貼后,回車兩次,顯示請求內容;post請求頭,黏貼完畢后,回車,輸入post請求參數字符串,自動顯示請求內容
