這篇文章主要介紹了php使用socket調(diào)用http和smtp協(xié)議,結合實例形式總結分析了php使用socket發(fā)送http請求、post請求、SMTP請求、郵件發(fā)送等相關操作技巧,需要的朋友可以參考下

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);
