用flash as3截取攝像頭圖片信息交由php保存[flash+php保存圖片]

 

前段時間做了一個類似的應用，現將源代碼公佈。(請自行配置php和gd2庫)
Flash as3:(放到幀上，可自行修改移至相關class)

1. function clickHandler(e:MouseEvent):void
2. {
3.     var bitmapdata:BitmapData = new BitmapData(video.width, video.height);
4.     bitmapdata.draw(video);
5.     var jpgEncoder:JPGEncoder = new JPGEncoder(80);//圖片質量
6.     var jpgStream:ByteArray = jpgEncoder.encode(bitmapdata);
7.     var header:URLRequestHeader = new URLRequestHeader ("Content-type", "application/octet-stream");
8.     var jpgURLRequest:URLRequest = new URLRequest ("http://localhost/jpg_encoder_download.php?name=camera.jpg"); //此web url請自行修改
9.     jpgURLRequest.requestHeaders.push(header);
10.     jpgURLRequest.method = URLRequestMethod.POST;
11.     jpgURLRequest.data = jpgStream;
12.     navigateToURL(jpgURLRequest, "_blank");
13. }
14. var video:Video = new Video;
15. addChild(video);
16. video.attachCamera(Camera.getCamera());
17. var btn:Sprite = new Sprite;
18. btn.graphics.beginFill(0,1);
19. btn.graphics.drawRoundRect(0,0,100,25,10);
20. btn.x = 110;
21. btn.y = 250;
22. btn.buttonMode = true;
23. btn.addEventListener(MouseEvent.CLICK, clickHandler);
24. addChild(btn);

兩個類文件BitString.as, JPGEncoder.as，下載後注意大小寫，此wp不知道咋整的，把偶上傳時的大寫都改成小寫了。
php:

1. <?php
2. if ( isset ( $GLOBALS["HTTP_RAW_POST_DATA"] )) {
3.     // get bytearray
4.     $im = $GLOBALS["HTTP_RAW_POST_DATA"];
5.     // add headers for download dialog-box
6.     header('Content-Type: image/jpeg');
7.     header("Content-Disposition: attachment; filename=".$_GET['name']);
8.     echo $im;
9. }  else echo 'An error occured.';
10. ?>
