从 Flash 保存图像，将其发送到 PHP 并将 URL 字符串-php问题

Save image from Flash, send it to PHP and return a URL string to Flash(从 Flash 保存图像，将其发送到 PHP 并将 URL 字符串返回给 Flash)

本文介绍了从 Flash 保存图像，将其发送到 PHP 并将 URL 字符串返回给 Flash的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！

问题描述

我使用此代码将图像转换为 BitmapData 并将 JPG 存储在 ByteArray 中.

I use this code to convert an image to a BitmapData and store a JPG in a ByteArray.

import com.adobe.images.JPGEncoder;

var jpgSource:BitmapData = new BitmapData (img_mc.width, img_mc.height);
jpgSource.draw(img_mc);

var jpgEncoder:JPGEncoder = new JPGEncoder(85);
var jpgStream:ByteArray = jpgEncoder.encode(jpgSource);

// here we need some code to send the bytearray but I lack enough knowledge to do it by myself


现在，我想做以下事情:1.将ByteArray发送到PHP；2、PHP必须在服务器上存储一个物理image_id.jpg；3.然后PHP必须将图片的URL返回给Flash；
Now, I want to do the following:
1. send the ByteArray to PHP;
2. PHP must store a physical image_id.jpg on server;
3. then PHP must return the URL of the image to Flash;
这可能吗?怎么样?
PHP 的第一行可能是:
The first lines of PHP could be:
if (isset($GLOBALS["HTTP_RAW_POST_DATA"]))
{
    // get bytearray
    $jpg = $GLOBALS["HTTP_RAW_POST_DATA"];

    // but I don't know how to save the image on disk and how to return the URL of the //image
}

谢谢！

import com.adobe.images.JPGEncoder;
import flash.events.Event;
import flash.net.URLLoader;
import flash.net.URLRequestHeader;
import flash.net.URLRequest;
var jpgSource:BitmapData = new BitmapData(img_mc.width,img_mc.height);jpgSource.draw(img_mc);var jpgEncoder:JPGEncoder = new JPGEncoder(85);var jpgStream:ByteArray = jpgEncoder.encode(jpgSource);
var jpgSource:BitmapData = new BitmapData(img_mc.width,img_mc.height);
jpgSource.draw(img_mc);
var jpgEncoder:JPGEncoder = new JPGEncoder(85);
var jpgStream:ByteArray = jpgEncoder.encode(jpgSource);
//设置请求的头部、方法和数据var header:URLRequestHeader = new URLRequestHeader("Content-type","application/octet-stream");var loader:URLLoader = new URLLoader();//发送jpg字节到saveJPG.php脚本var myRequest:URLRequest = new URLRequest("saveJPG.php");myRequest.requestHeaders.push(header);myRequest.method = URLRequestMethod.POST;myRequest.data = jpgStream;loader.load(myRequest);//触发完成事件；loader.addEventListener(Event.COMPLETE,saved);保存的功能(e:事件){//跟踪图像文件名跟踪(装载机数据)；}
//set the request's header,method and data
var header:URLRequestHeader = new URLRequestHeader("Content-type","application/octet-stream");
var loader:URLLoader = new URLLoader();
//sends jpg bytes to saveJPG.php script
var myRequest:URLRequest = new URLRequest("saveJPG.php");
myRequest.requestHeaders.push(header);
myRequest.method = URLRequestMethod.POST;
myRequest.data = jpgStream;
loader.load(myRequest);
//fire complete event;
loader.addEventListener(Event.COMPLETE,saved);
function saved(e:Event)
{
    //trace the image file name
    trace(loader.data);
}


 php (saveJPG.php) 部分:
the php (saveJPG.php) part:


if ( isset ( $GLOBALS["HTTP_RAW_POST_DATA"] )) {
//the image file name   
$fileName = 'img.jpg';

// get the binary stream
$im = $GLOBALS["HTTP_RAW_POST_DATA"];

//write it
$fp = fopen($fileName, 'wb');
fwrite($fp, $im);
fclose($fp);

//echo the fileName;
echo $fileName;

} else echo 'result=发生错误.';
}  else echo 'result=An error occured.';
