[php] php curl smtp发送邮件

公司的云平台把fsockopen关掉了,如果要使用smtp外网的邮箱来发送邮件的话 只能试试使用curl来进行了

先google了一下,发现很多问相关问题的但没有相关的解答,在phpclasses里也没有找到相关的类于是自己边看stmp的相关协议边开始尝试curl

SMTP协议

这个在网上可以找到多相关的例子,可以自己实验一下使用telnet去连接mail服务器

$ telnet 邮箱SMTP服务地址 25Trying 邮箱服务IP地址...Connected to 邮箱SMTP服务地址.Escape character is '^]'.220 exchange邮箱服务器地址 Microsoft ESMTP MAIL Service ready at Sat, 2 Jun 2012 15:02:12 +0800EHLO 127.0.0.1250-exchange邮箱服务器地址 Hello [邮箱服务IP地址]250-SIZE250-PIPELINING250-DSN250-ENHANCEDSTATUSCODES250-X-ANONYMOUSTLS250-AUTH NTLM LOGIN250-X-EXPS GSSAPI NTLM250-8BITMIME250-BINARYMIME250-CHUNKING250-XEXCH50250 XRDSTAUTH LOGIN334 VXNlcm5hbWU6用户名(base64_encode)334 UGFzc3dvcmQ6密码(base64_encode)235 2.7.0 Authentication successfulMAIL FROM:发件箱地址250 2.1.0 Sender OKRCPT TO:收件箱地址250 2.1.5 Recipient OKDATA354 Start mail input; end with .要发送的内容(这里的相关的规范有很多).250 2.6.0 <0b476f30-3b96-4e3d-84d2-395a96d34000@exchange邮箱服务器地址> Queued mail for deliveryQUIT221 2.0.0 Service closing transmission channelConnection closed by foreign host.

php测试代码:

 1  "邮箱SMTP服务器地址", 5     "port"     => "邮箱SMTP服务器端口", // 一般为25 6     "username" => "用户名", 7     "password" => "密码", 8     "from"     => "发件地址", 9     "to"       => "收件地址",10     "subject"  => "测试一下标题",11     "body"     => "测试一下内容"12 );13 14 $CRLF = "\r\n";15 $test = "";16 $curl = curl_init();17 18 curl_setopt($curl, CURLOPT_URL, $smtp['url']);19 curl_setopt($curl, CURLOPT_PORT, $smtp['port']);20 curl_setopt($curl, CURLOPT_TIMEOUT,10);21 22 function inlineCode($str){23         $str = trim($str);24         return $str?'=?UTF-8?B?'.base64_encode($str).'?= ':'';25 }26 27 function buildHeader($headers){28     $ret = '';29     foreach($headers as $k=>$v){30         $ret.=$k.': '.$v."\n";31     }32     return $ret;33 }34 35 // 36 $header = array(37     'Return-path'=>'<'.$smtp['from'].'>',38     'Date'=>date('r'),39     'From'=> '<'.$smtp['from'].'>',40     'MIME-Version'=>'1.0',41     'Subject'=>inlineCode($smtp['subject']),42     'To'=>$smtp['to'],43     'Content-Type'=>'text/html; charset=UTF-8; format=flowed',44     'Content-Transfer-Encoding'=>'base64'45 );46 $data = buildHeader($header).$CRLF.chunk_split(base64_encode($smtp['body']));47 48 49 $content  = "EHLO ".$smtp["url"].$CRLF; // 先得hello一下50 $content .= "AUTH LOGIN".$CRLF.base64_encode($smtp["username"]).$CRLF.base64_encode($smtp["password"]).$CRLF; // 验证登陆51 $content .= "MAIL FROM:".$smtp["from"].$CRLF; // 发件地址52 $content .= "RCPT TO:".$smtp["to"].$CRLF;  // 收件地址53 $content .= "DATA".$CRLF.$data.$CRLF.".".$CRLF; // 发送内容54 $content .= "QUIT".$CRLF; // 退出55 56 curl_setopt($curl, CURLOPT_RETURNTRANSFER, true);    // curl接收返回数据57 curl_setopt($curl, CURLOPT_CUSTOMREQUEST, $content);58 $test = curl_exec($curl);59 var_dump($test);60 echo "
\r\n";61 var_dump($content);62 63 // 结束64 curl_close($curl);

以上只是测试的php

包测试+修改花了近6个小时让产品的代码兼容了fsockopen和curl

以后有空写个兼容fsockopen和curl简单发送邮件的smtp类
