php使用socket调用http和smtp协议实例小结


						本文实例讲述了php使用socket调用http和smtp协议。分享给大家供大家参考，具体如下：

socket发送HTTP请求

http协议请求报文格式

get





## 请求方法 请求文件路径?查询字符串 HTTP/协议版本号

## Host: 主机名:端口号

## Connection:close







post





## 请求方法 请求文件路径 HTTP/协议版本号

## Host: 主机名:端口号

## Content-type: application/x-www-form-urlencoded

## Content-length： 查询字符串长度

## Connection: close

## 查询字符串







api.php





<?php

echo $_SERVER["REQUEST_METHOD"]."<br/>";

print_r($_REQUEST);







fsocketopen发送get请求





<?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扩展发送post请求





<?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发送smtp请求

首先通过socket连接到smtp服务器，例如smtp.163.com 25，然后实现smtp发送邮件的必须参数即可。



HELO 主机名

AUTH LOGIN base64编码之后的发件人邮箱

base64编码之后的密码

##填写信封

MAIL FROM:<发件人邮箱>

RCPT TO:<收件人邮箱>

##填写信件内容

DATA

MIME-Version:1.0

To: 收件人邮箱

From: 发件人邮箱

Subject： 邮件主题

邮件内容



fsocketopen发送邮件

fsocketopen和pfsocketopen是php机制本身的函数，可以直接调用，不需要安装扩展。以上两个函数可以打开一个网络连接或者一个Unix套接字连接，然后我们可以使用fwrite,fread,fclose,feof等函数直接操作该网络连接。





<?php

$user = "root@163.com";

$password = "root";

$mailto = "1234567@qq.com";

$subject = "fsocketopen发送邮件";

$body = "收到邮件了么，亲";

$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扩展发送邮件

sockets扩展的功能更加强大，可以搭建tcp/ip服务器，不过我们使用smtp协议发送邮件的例子，只需要使用到socket客户端的功能。





 <?php

$user = "root@163.com";

$password = "root";

$mailto = "1234567@qq.com";

$subject = "sockets扩展发送邮件";

$body = "收到邮件了么，亲";

$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);
