编程

1、下载class.phpmailer.php和class.smtp.php至公共库

2、编写发邮件的公共函数

function sendMail($param) {
        $config = C("THINK_EMAIL");
        vendor("PHPMailer.class#phpmailer"); //从PHPMailer目录导class.phpmailer.php类文件
        $mail = new PHPMailer(); //PHPMailer对象
        $mail->CharSet = $config["EMAIL_CHARSET"]; //设定邮件编码，默认ISO-8859-1，如果发中文此项必须设置，否则乱码
        $mail->IsSMTP();  // 设定使用SMTP服务
        $mail->SMTPDebug = 0;   // 关闭SMTP调试功能
        // 1 = errors and messages
        // 2 = messages only
        $mail->SMTPAuth = $config["EMAIL_SMTPAUTH"];   // 启用 SMTP 验证功能
        $mail->Host = $config["SMTP_HOST"];  // SMTP 服务器
        $mail->Port = $config["SMTP_PORT"];  // SMTP服务器的端口号
        $mail->Username = $config["SMTP_USER"];  // SMTP服务器用户名
        $mail->Password = $config["SMTP_PASS"];  // SMTP服务器密码
        //$mail->SetFrom($config["FROM_EMAIL"], $config["FROM_NAME"]);
        $mail->SetFrom($param["mail_from"], $param["mail_name"]);
        $replyEmail = $config["REPLY_EMAIL"] ? $config["REPLY_EMAIL"] : $param["mail_from"];
        $replyName = $config["REPLY_NAME"] ? $config["REPLY_NAME"] : $param["mail_name"];
        $mail->AddReplyTo($replyEmail, $replyName);
        if (!empty($param["to"])) {
            foreach ($param["to"] as $to) {
                $mail->AddAddress($to["address"], $to["name"]);
            }
        }
        if (!empty($param["cc"])) {
            foreach ($param["cc"] as $cc) {
                $mail->addCC($cc["address"], $cc["name"]);
            }
        }
//        if (!empty($param["bcc"])) {
//            foreach ($param["bcc"] as $bcc) {
//                $mail->addBCC($bcc["address"], $bcc["name"]);
//            }
//        }
        $param["body"] = $mail->WrapText($param["body"], 900);
        $mail->Subject = $param["subject"];
        if (!empty($param["body"])) {
            $mail->MsgHTML($param["body"]);
            $mail->IsHTML($config["EMAIL_ISHTML"]);
            $mail->Body = $param["body"];
        }
//        if (!empty($param["attachment"])) { // 添加附件
//            foreach ($param["attachment"] as $file) {
//                if (is_file($file["path"])) {
//                    $mail->AddAttachment($file["path"], $file["name"]);
//                }
//            }
//        }
        for($i=0;$i<(count($param["attachment"]));$i++){
            $img=substr($param["attachment"][$i], strpos($param["attachment"][$i], ","));
            $mail->AddStringAttachment(base64_decode($img),"attach".$i.".png","base64","image/png");
        }
        //重发机制
        $ret["errno"] = 0;
        $ret["msg"] = "";
        if ($mail->Send()) {
            return $ret;
        } else {
            if ($mail->Send()) {
                return $ret;
            } else {
                $ret["errno"] = 1;
                $ret["msg"] = $mail->ErrorInfo;
                return $ret;
            }
        }
        // return $mail->Send() ? true : $mail->ErrorInfo;
    }

3、SMTP配置函数

// 配置邮件发送服务器
"THINK_EMAIL"=>array(
    "SMTP_HOST"   =>  "localhost",  //邮件发送SMTP服务器
    "SMTP_PORT"   => "25",//SMTP服务器端口  
    "SMTP_USER"   =>  "admin", //SMTP服务器登陆用户名
    "SMTP_PASS"   =>  "admin", //SMTP服务器登陆密码 
    "FROM_EMAIL"  =>"发件箱@XX.com",
    "FROM_NAME"  =>"发件人姓名",
    "REPLY_EMAIL" =>"",
    "REPLY_NAME"  =>"",
    "EMAIL_CHARSET" =>"utf-8",
    "EMAIL_ISHTML" => "TRUE",
    "EMAIL_SMTPAUTH" => "0",
    ),

4、根据库中存的Base64获取图片信息，实际调用的为一个URL

public function getImage() {
    $reportId = I("request.id");
    $imgInfos = I("request.img");
    header("Content-Type: image/png");
    $repotModel = M("XXX");
    $report = $repotModel->where(["id"=>$reportId])->find();
    $base = explode(",", $report[$imgInfos])[1];
    $base = base64_decode($base);
    echo $base;
    die();
}
