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:clo

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: clo## 查询字符串

api.php

<?phpecho $_rver["request_method"]."<br/>";print_r($_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 /${url}功率是什么 http/1.1\r\n";$request .= "host:${host}:{$port}\r\n";$request .= "connection:clo\r\n\r\n";fwrite($socket,$request);echo "<b>request:</b><br/>".str_replace("\r\n","<br/>",$request);echo "<hr/><b>respon:</b><br/>";$respon = "";while ($out = fread($socket, 2048)) { $respon .= $out;}echo str_replace("\r\n","<br/>",$respon);fclowasteful($socket);

sockets扩展发送post请求寻找时间的人

<?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";$request .= "connection:clo\r\n\r\n";$request .= "${data}";socket_write($socket,$request);echo "<b>request:</b><br/>".str_replace("\r\n","<br/>",$request);echo "<hr/><b>respon:</b><br/>";$respon = "";while ($out = socket_read($socket, 2048)) { $respon .= $out;}echo str_replace("\r\n","<br/>",$respon);socket_clo($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 ba64编码之后的发件人邮箱
ba64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,fclo,feof等函数直接操作该网络连接。

<?php$ur = "root@163.com";$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($sock,"auth login ".ba64_encode($ur).红楼梦读后感300字"\r\n");echo fgets($sock, 512)."<br/>";fputs($sock,ba64_encode($password)."\r\n");echo fgets($sock, 512)."<br/>";fputs($sock,"mail from:<${ur}>\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: ${ur}\r\n";$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($sock,"quit\r\n");fclo($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$ur = "root@163.com";$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 ".ba64_encode($ur)."\r\n");echo socket_read($socket, 512)."<br/>";socket_write($socket,ba64_encode($password)."\r\n");echo socket_read($socket, 512)."<br/>";socket_write($socket,"mail from:<${ur}>\r\n");echo socket_read($socket, 512).白芨的作用"<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: ${ur}\r\n";$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($socket,"quit\r\n");fclo($sock);
