PHPmailer发送邮件时的常见问题及解决办法
来源:http://www.chinastor.com/a/jishu/mailserver/0G392262014.html
使用PHPmailer发送邮件时的常见问题总结: 一,没有定义发送邮箱$mail->From或格式不正确,错误提示:Language string failed to load: recipients_failed test@chinastor.com,注意,这个配置一定要正确,而且是正确的邮箱 二,没有定义邮件服务主机$mail->Host或连接失败,错误提示:Language string failed to load: connect_host 三,没有定义发送邮箱$mail->AddAddress或邮箱格式不正确,错误提示:Language string failed to load: provide_address 四,没有定义邮箱发送用户名$mail->Username,错误提示:Language string failed to load: connect_host 五,没有定义邮箱发送密码$mail->Password,错误提示:Language string failed to load: connect_host,这类错误非常明显,一般都是邮箱服务器配置不正确不能边接。 六,邮件正文编码,如果发送HTML邮件,需要定义正确的编码格式和字符,发送GBK邮件如下: $mail->IsHTML ( true ); 是否支持HTML邮件 $mail->CharSet = "GB2312"; 字符设置 $mail->Encoding = "base64"; 编码方式 配置后可直接发送HTML邮件,如下: <html> <head> <meta http-equiv="Content-Type" content="text/html; charset=gb2312" /> <title>PHPMailer邮件测试</title> </head> <body> <div>PHPMailer邮件类使用错误分析</div> </body> </html> 七,学会正确使用错误提示$mail->ErrorInfo查看邮件错误,可直接查找问题。 使用PHPMailer邮件类发送邮件使用非常简单,基本配置如上所示,在使用过程中正确了解错误提示,并及时了解错误原因,对于正确使用PHPMailer邮件类来说非常重要。 我们有时做mail群发,可能到不少问题,一些常见的错误网上很多但没有答案,但是自己不断摸索,总会有结果,现在把我遇见的一些常见问题及解决方法分享! 要做发送邮件功能,首先要明白邮件收发的原理,引用网上的一段话比较容易懂: 在Internet上将一段文本信息从一台计算机传送到另一台计算机上,可通过两种协议来完成,即SMTP(Simple Mail Transfer Protocol,简单邮件传输协议)和POP3(Post Office Protocol,邮局协议3)。SMTP是Internet协议集中的邮件标准。在Internet上能够接收电子邮件的服务器都有SMTP。电子邮件在发送前,发件方的SMTP服务器与接收方的SMTP服务器联系,确认接收方准备好了,则开始邮件传递;若没有准备好,发送服务器便会等待,并在一段时间后继续与接收方邮件服务器联系。这种方式在Internet上称为“存储——转发”方式。POP3可允许E-mail客户向某一SMTP服务器发送电子邮件,另外,也可以接收来自SMTP服务器的电子邮件。换句话说,电子邮件在客户PC机与服务提供商之间的传递是通过P0P3来完成的,而电子邮件在 Internet上的传递则是通过SMTP来实现。 如果觉得不够清楚的话,则引用网上的一张图来解释吧: 使用PHPmailer发送邮件时的常见问题及解决办法 有关phpmailer的介绍可以参考phpmailer官网 1.SMTP Error: Could not authenticate. 这个是因为smtp验证没通过,就是smtp server 的用户名和密码不正确了 $mail->Username = "smtp@chinastor.com"; // SMTP server username t;Password = "******"; $mail->Username = "smtp@chinastor.com"; // SMTP server username $mail->Password = "******"; 2.Could not execute: /usr/sbin/sendmail 这是因为 $mail->IsSendmail(); // tell the class to use Sendmail $mail->IsSendmail(); // tell the class to use Sendmail 去掉上面的代码就ok了! 3.关于phpmailer发送邮件产生中文乱码问题 环境一:在普通环境,即标题内容等含中文的内容是在脚本中加上去的,或从文本中获取的,只需要进行如下操作(网上有很多): 修改class.phpmailer.php中的EncodeHeader函数,改为: public function EncodeHeader($str, $position = 'text', $pl = 0) { $x = 0; if ($pl){return "=?".$this->CharSet."?B?".base64_encode($str)."?=";} public function EncodeHeader($str, $position = 'text', $pl = 0) { $x = 0; if ($pl){return "=?".$this->CharSet."?B?".base64_encode($str)."?=";} 再改下使用这个函数的一段: if($this->Mailer != 'mail') { $result .= $this->HeaderLine('Subject', $this->EncodeHeader($this->SecureHeader($this->Subject),'text',1)); } if($this->Mailer != 'mail') { $result .= $this->HeaderLine('Subject', $this->EncodeHeader($this->SecureHeader($this->Subject),'text',1)); } 当然编码设置也不能少了: $mail->CharSet="utf-8"; $mail->Encoding = "base64"; $mail->CharSet="utf-8"; $mail->Encoding = "base64"; 环境二:从excel中提取内容然后再发送excel中的内容给用户,这个折腾了我好久。最终找到解决办法了。最关键的地方是:excel中的编码是html格式的unicode,所以得使用下面这个函数将其转化为utf8,这个帖子的最后回复的人帮了我,谢谢他!帖子地址是:http://www.phpchina.com/bbs/viewthread.php?tid=111554 private function uc2html($str) { $ret = ''; for( $i=0; $i<strlen($str)/2; $i++ ) { $charcode = ord($str[$i*2])+256*ord($str[$i*2+1]); $ret .= '&#'.$charcode.';'; } return mb_convert_encoding($ret,'UTF-8','HTML-ENTITIES'); } private function uc2html($str) { $ret = ''; for( $i=0; $i<strlen($str)/2; $i++ ) { $charcode = ord($str[$i*2])+256*ord($str[$i*2+1]); $ret .= '&#'.$charcode.';'; } return mb_convert_encoding($ret,'UTF-8','HTML-ENTITIES'); } 下面贴段测试代码: <?php /** * Simple example script using PHPMailer with exceptions enabled * @package phpmailer * @version $Id$ */ require '../class.phpmailer.php'; try { $mail = new PHPMailer(true); //New instance, with exceptions enabled $body = file_get_contents('contents.html'); $body = preg_replace('/\\\\/','', $body); //Strip backslashes $mail->IsSMTP(); // tell the class to use SMTP $mail->SMTPAuth = true; // enable SMTP authentication $mail->Port = 25; // set the SMTP server port $mail->Host = "smtp.xchinastor.com"; // SMTP server $mail->Username = "xxx@chinastor.com"; // SMTP server username $mail->Password = "xxxx"; // SMTP server password $mail->IsSendmail(); // tell the class to use Sendmail $mail->AddReplyTo("xxx@sina.com","xxxx"); $mail->From = "xxxx@m6699.com"; $mail->FromName = "DJB"; $to = "xxx@sina.com"; $mail->AddAddress($to); $mail->Subject = "First PHPMailer Message"; $mail->AltBody = "To view the message, please use an HTML compatible email viewer!"; // optional, comment out and test $mail->WordWrap = 80; // set word wrap $mail->MsgHTML($body); $mail->IsHTML(true); // send as HTML $mail->Send(); echo 'Message has been sent.'; } catch (phpmailerException $e) { echo $e->errorMessage(); } ?> 一.class.phpmailer.php文件 <?php /*~ class.phpmailer.php .---------------------------------------------------------------------------. | Software: PHPMailer - PHP email class | | Version: 5.1 | | Contact: via sourceforge.net support pages (also www.worxware.com) | | Info: http://phpmailer.sourceforge.net | | Support: http://sourceforge.net/projects/phpmailer/ | | ------------------------------------------------------------------------- | | Admin: Andy Prevost (project admininistrator) | | Authors: Andy Prevost (codeworxtech) codeworxtech@users.sourceforge.net | | : Marcus Bointon (coolbru) coolbru@users.sourceforge.net | | Founder: Brent R.
