Flex和PHP-发送电子邮件附件

Question

我希望访问者能够将我创建的应用程序中的创建内容作为附件发送给朋友（就像创建的屏幕截图一样）。 我可以让Flex和PHP进行通信并发送电子邮件，但是无法发送图像。 它发送的附件不超过2o，无法打开（当然！）。

我没有从我的应用程序中返回错误

我发现下面链接了这些帖子，这对我有所帮助，但是我仍然不知道如何将图像从Flex传递到PHP。

• 将整个Flash文档另存为JPEG，以附件形式通过电子邮件发送

这是我来自Flex的代码：

private function sendMail():void{
            var _nomSTF:String = nomSTF.text;
            var _emailSTF:String = emailSTF.text;
            var _emailFriendSTF:String = emailFriendSTF.text;
            var _sujetSTF:String = sujetSTF.text;
            var _messageSTF:String = messageSTF.text;

            //IMAGE
            var fr:FileReference = new FileReference();
            var encoder:PNGEncoder = new PNGEncoder();

            var screenshotData:BitmapData = new BitmapData(conteneurDeMonImage.width, conteneurDeMonImage.height, true, 0xFFFFFF);

            screenshotData.draw(conteneurDeMonImage);
            //var outputData:ByteArray = encoder.encode(screenshotData);
            //var base64:Base64Encoder = new Base64Encoder();
            var png:PNGEncoder = new PNGEncoder();
            byteArray = png.encode(screenshotData);

            //base64.encodeBytes(outputData);
            //FIN IMAGE


            var evValidMail:ValidationResultEvent = emailSTFValidator.validate();
            var evValidMailFriend:ValidationResultEvent = emailFriendSTFValidator.validate();
            var evValidName:ValidationResultEvent = nomSTFValidator.validate();

            if (evValidMail.type == ValidationResultEvent.VALID
                && evValidName.type == ValidationResultEvent.VALID
                && evValidMailFriend.type == ValidationResultEvent.VALID){
                emailService.send({senderName: _nomSTF, senderEmail:_emailSTF, emailFriendSTF: _emailFriendSTF,
                    emailSubject:_sujetSTF, emailMessage: _messageSTF, file : byteArray});
            } else {
                resultLabel.text="There are Form errors";
                resultLabel.setStyle("styleName", "invalid");
            }
        }

        private function emailResultSTF():void{
            Alert.show("Votre message a bien été envoyé");
            containerSendToFriend.visible = false;
        }
<fx:Declarations>

    <s:HTTPService id="emailService" url="src/mail.php" method="POST"
                    resultFormat="xml" useProxy="false"
                    result="emailResultSTF()"
                    fault="Alert.show(event.fault.faultString + '\n' + event.fault.faultDetail + '\n' + event.message.toString())"/>

</fx:Declarations>

这是我的PHP代码：

$fileatt_type = "application/octet-stream"; 
$fileatt_name = "baignoireElyseeConcept.png";
$sender_name =  $_POST['senderName'];
$email_from = $_POST['senderEmail']; 
$email_subject = $_POST['emailSubject'];  
$email_message = $_POST['emailMessage'];  

$email_to = $_POST['emailFriendSTF']; 

$headers = 'From:'.$sender_name.'<'.$email_from.'>';   

$data= $_POST['file'];

$semi_rand = md5(time());   
$mime_boundary = "==Multipart_Boundary_x{$semi_rand}x";   

$headers .= "\nMIME-Version: 1.0\n" .   
            "Content-Type: multipart/mixed;\n" .   
            " boundary=\"{$mime_boundary}\"";   

$email_message = "This is a multi-part message in MIME format.\n\n" .   
                "--{$mime_boundary}\n" .   
                "Content-Type:text/html; charset=\"utf-8\"\n" .   
               "Content-Transfer-Encoding: 7bit\n\n" .   
$email_message . "\n\n";   


$email_message .= "--{$mime_boundary}\n" .   
                  "Content-Type: {$fileatt_type};\n" .   
                  " name=\"{$fileatt_name}\"\n" .
                  "Content-Transfer-Encoding: base64\n\n" .   
                 $data . "\n\n" .   
                  "--{$mime_boundary}--\n";   

$mailsend = mail($email_to, $email_subject, $email_message, $headers);

我已经寻找了好几天的答案，终于使它起作用，所以这就是我的工作方式（在Internet上有很多资源，特别是在以下资源的帮助下： http : //j-query.blogspot.com /2011/02/save-base64-encoded-canvas-image-to-png.html ）

这是我的图片的Flex代码：

var je:JPEGEncoder = new JPEGEncoder(100); 

var bd:BitmapData = new BitmapData(conteneurDeMonImage.width,conteneurDeMonImage.height);
bd.draw(conteneurDeMonImage);

var ba:ByteArray = je.encode(bd);

var be:Base64Encoder = new Base64Encoder();
be.encodeBytes(ba);

var encodedData:String = be.toString();

            // Testing if my base64 is working in FLEX
            /*var byteArr:ByteArray;
            var B64dec:Base64Decoder = new Base64Decoder();
            B64dec.decode(encodedData);
            byteArr = B64dec.toByteArray();
            imageEnGrand.load(byteArr);*/

emailService.send({senderName: _nomSTF, senderEmail:_emailSTF, emailFriendSTF: _emailFriendSTF, emailSubject:_sujetSTF, emailMessage: _messageSTF, file : encodedData});

这是我的PHP代码：

$fileatt_type = "application/octet-stream"; 
$fileatt_name = "test.jpg"; 

$sender_name =  $_POST['senderName'];
$email_from = $_POST['senderEmail']; 
$email_subject = $_POST['emailSubject'];  
$email_message = $_POST['emailMessage'];  

$email_to = $_POST['emailFriendSTF']; 

$headers = 'From:'.$sender_name.'<'.$email_from.'>';   

$data = $_POST['file'];

$data = str_replace('data:image/png;base64,', '', $data);
$data = str_replace(' ', '+', $data);

$img_data = base64_decode($data);
$png = chunk_split(base64_encode(($img_data)));

$semi_rand = md5(time());   
$mime_boundary = "==Multipart_Boundary_x{$semi_rand}x";   

$headers .= "\nMIME-Version: 1.0\n"."Content-Type: multipart/mixed;\n"." boundary=\"{$mime_boundary}\"";   

$email_message =
                "This is a multi-part message in MIME format.\n\n".
                "--{$mime_boundary}\n"."Content-Type:text/html; charset=\"utf-8\"\n".
                "Content-Transfer-Encoding: 7bit\n\n".$email_message."\n\n";

$email_message .= "--{$mime_boundary}\n" .   
                  "Content-Type: {$fileatt_type};\n" .   
                  " name=\"{$fileatt_name}\"\n" .
                  "Content-Transfer-Encoding: base64\n\n" .   
                 $png . "\n\n" .   
                  "--{$mime_boundary}--\n";   

$mailsend = mail($email_to, $email_subject, $email_message, $headers);

希望对与我有同样问题的人有所帮助！
