公司的雲平台把fsockopen關掉了,如果要使用smtp外網的郵箱來發送郵件的話 只能試試使用curl來進行了
先google了一下,發現很多問相關問題的但沒有相關的解答,在phpclasses裡也沒有找到相關的類於是自己邊看stmp的相關協議邊開始嘗試curl
SMTP協議
這個在網上可以找到多相關的例子,可以自己實驗一下使用telnet去連接mail服務器
$ telnet 郵箱SMTP服務地址 25

php測試代碼:
1 <?php
2 header("content-type:text/html;charset=utf-8");
3 $smtp = array(
4 "url" => "郵箱SMTP服務器地址",
5 "port" => "郵箱SMTP服務器端口", // 一般為25
6 "username" => "用戶名",
7 "password" => "密碼",
8 "from" => "發件地址",
9 "to" => "收件地址",
10 "subject" => "測試一下標題",
11 "body" => "測試一下內容"
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; // 驗證登陸
51 $content .= "MAIL FROM:".$smtp["from"].$CRLF; // 發件地址
52 $content .= "RCPT TO:".$smtp["to"].$CRLF; // 收件地址
53 $content .= "DATA".$CRLF.$data.$CRLF.".".$CRLF; // 發送內容
54 $content .= "QUIT".$CRLF; // 退出
55
56 curl_setopt($curl, CURLOPT_RETURNTRANSFER, true); // curl接收返回數據
57 curl_setopt($curl, CURLOPT_CUSTOMREQUEST, $content);
58 $test = curl_exec($curl);
59 var_dump($test);
60 echo "<br/>\r\n";
61 var_dump($content);
62
63 // 結束
64 curl_close($curl);
以上只是測試的php
包測試+修改花了近6個小時讓產品的代碼兼容了fsockopen和curl
以後有空寫個兼容fsockopen和curl簡單發送郵件的smtp類
think in coding
