本文實例講述了php使用socket調(diào)用http和smtp協(xié)議。分享給大家供大家參考，具體如下：
socket發(fā)送HTTP請求
http協(xié)議請求報文格式
get
## 請求方法 請求文件路徑?查詢字符串 HTTP/協(xié)議版本號
## Host: 主機名:端口號
## Connection:close
post
## 請求方法 請求文件路徑 HTTP/協(xié)議版本號
## Host: 主機名:端口號
## Content-type: application/x-www-form-urlencoded
## Content-length： 查詢字符串長度
## Connection: close
## 查詢字符串
api.php
?php
echo $_SERVER["REQUEST_METHOD"]."br/>";
print_r($_REQUEST);
fsocketopen發(fā)送get請求
?php
$url = "api.php";
$host = "127.0.0.1";
$port = 8080;
$param = ["name"=>"zhezhao","age"=>23];
$url .= "?".http_build_query($param);
$socket = fsockopen($host,$port,$errno,$errstr,10);
$request = "GET /${url} HTTP/1.1\r\n";
$request .= "Host:${host}:{$port}\r\n";
$request .= "Connection:close\r\n\r\n";
fwrite($socket,$request);
echo "b>Request:/b>br/>".str_replace("\r\n","br/>",$request);
echo "hr/>b>Response:/b>br/>";
$response = "";
while ($out = fread($socket, 2048)) {
$response .= $out;
}
echo str_replace("\r\n","br/>",$response);
fclose($socket);
sockets擴展發(fā)送post請求
?php
$url = "api.php";
$host = "127.0.0.1";
$port = 8080;
$param = ["name"=>"zhezhao","age"=>23];
$data = http_build_query($param);
$socket = socket_create(AF_INET, SOCK_STREAM, SOL_TCP);
socket_connect($socket, $host,$port);
$request = "POST /${url} HTTP/1.1\r\n";
$request .= "Host:${host}:{$port}\r\n";
$request .= "Content-type:application/x-www-form-urlencoded\r\n";
$request .= "Content-length:".strlen($data)."\r\n";
$request .= "Connection:close\r\n\r\n";
$request .= "${data}";
socket_write($socket,$request);
echo "b>Request:/b>br/>".str_replace("\r\n","br/>",$request);
echo "hr/>b>Response:/b>br/>";
$response = "";
while ($out = socket_read($socket, 2048)) {
$response .= $out;
}
echo str_replace("\r\n","br/>",$response);
socket_close($socket);
socket發(fā)送smtp請求
首先通過socket連接到smtp服務器，例如smtp.163.com 25，然后實現(xiàn)smtp發(fā)送郵件的必須參數(shù)即可。
HELO 主機名
AUTH LOGIN base64編碼之后的發(fā)件人郵箱
base64編碼之后的密碼
##填寫信封
MAIL FROM:發(fā)件人郵箱>
RCPT TO:收件人郵箱>
##填寫信件內(nèi)容
DATA
MIME-Version:1.0
To: 收件人郵箱
From: 發(fā)件人郵箱
Subject： 郵件主題
郵件內(nèi)容
fsocketopen發(fā)送郵件
fsocketopen和pfsocketopen是php機制本身的函數(shù)，可以直接調(diào)用，不需要安裝擴展。以上兩個函數(shù)可以打開一個網(wǎng)絡連接或者一個Unix套接字連接，然后我們可以使用fwrite,fread,fclose,feof等函數(shù)直接操作該網(wǎng)絡連接。
?php
$user = "root@163.com";
$password = "root";
$mailto = "1234567@qq.com";
$subject = "fsocketopen發(fā)送郵件";
$body = "收到郵件了么，親";
$sock = fsockopen("smtp.163.com",25);
fputs($sock,"HELO localhost\r\n");
echo fgets($sock, 512)."br/>";
fputs($sock,"AUTH LOGIN ".base64_encode($user)."\r\n");
echo fgets($sock, 512)."br/>";
fputs($sock,base64_encode($password)."\r\n");
echo fgets($sock, 512)."br/>";
fputs($sock,"MAIL FROM:${user}>\r\n");
echo fgets($sock, 512)."br/>";
fputs($sock,"RCPT TO:${mailto}>\r\n");
echo fgets($sock, 512)."br/>";
fputs($sock,"DATA\r\n");
echo fgets($sock, 512)."br/>";
$header = "MIME-Version:1.0\r\n";
$header .= "To: ${mailto}\r\n";
$header .= "From: ${user}\r\n";
$header .= "Subject: ${subject}\r\n";
fputs($sock, $header . "\r\n" . $body);
echo fgets($sock, 512)."br/>";
fputs($sock, "\r\n.\r\n");
echo fgets($sock, 512)."br/>";
fputs($sock,"QUIT\r\n");
fclose($sock);
sockets擴展發(fā)送郵件
sockets擴展的功能更加強大，可以搭建tcp/ip服務器，不過我們使用smtp協(xié)議發(fā)送郵件的例子，只需要使用到socket客戶端的功能。
?php
$user = "root@163.com";
$password = "root";
$mailto = "1234567@qq.com";
$subject = "sockets擴展發(fā)送郵件";
$body = "收到郵件了么，親";
$socket = socket_create(AF_INET, SOCK_STREAM, SOL_TCP);
socket_connect($socket, "smtp.163.com",25);
socket_write($socket,"HELO localhost\r\n");
echo socket_read($socket, 512)."br/>";
socket_write($socket,"AUTH LOGIN ".base64_encode($user)."\r\n");
echo socket_read($socket, 512)."br/>";
socket_write($socket,base64_encode($password)."\r\n");
echo socket_read($socket, 512)."br/>";
socket_write($socket,"MAIL FROM:${user}>\r\n");
echo socket_read($socket, 512)."br/>";
socket_write($socket,"RCPT TO:${mailto}>\r\n");
echo socket_read($socket, 512)."br/>";
socket_write($socket,"DATA\r\n");
echo socket_read($socket, 512)."br/>";
$header = "MIME-Version:1.0\r\n";
$header .= "To: ${mailto}\r\n";
$header .= "From: ${user}\r\n";
$header .= "Subject: ${subject}\r\n";
socket_write($socket, $header . "\r\n" . $body);
echo socket_read($socket, 512)."br/>";
socket_write($socket, "\r\n.\r\n");
echo socket_read($socket, 512)."br/>";
socket_write($socket,"QUIT\r\n");
fclose($sock);
