I have a sketch pad made in Flash AS3 like this one here: http://henryjones.us/articles/using-the-as3-jpeg-encoder

我想用 php 将 jpg 发送到服务器和一些来自 html 表单字段的数据.有没有办法在按下提交按钮时强制 Flash 电影传送图像文件?

I want to send the jpg to the server and some data from a html form field with php. Is there a way to force the Flash movie to deliver the image file when one presses the submit button?

推荐答案

这有点棘手:您可以通过以下两种方式之一进行:

it's a little tricky: You can do it one of two ways:

您需要修改URLRequestWrapper 插入字段需要的名称和文件名.这是我所做的:

You need to modify the URLRequestWrapper to insert field names and file names where needed. Here's what I've done:

bytes = '内容配置:表单数据；名称="' + $fieldName + '";文件名="';

bytes = 'Content-Disposition: form-data; name="' + $fieldName + '"; filename="';

它对标题进行了最多的格式化因此服务器可以将其理解为文件上传.

It does the most formatting of headers so the server could understand it as a file upload.

顺便说一下，如果你有一个 BitmapData您可能需要将其编码为 JPEG 或首先是 PNG.

By the way, if you have a BitmapData you might need to encode it to JPEG or PNG first.

我通常使用这个解决方案:

And I usually use this solution:

我没有使用过 imageshack API，但您可能想尝试使用 adobe 的 JPGEncoder 类 - 这是一个传递用户名和 JPG 字节数组的快速示例，它真的很简单.

I haven't used the imageshack API, but you may want to try using adobe's JPGEncoder class - here's a quick example that passes a username and the JPG's byte array, it's really quite simple.

private function savePicToServer(bmpData:BitmapData):void
{
    var jpgEncoder:JPGEncoder = new JPGEncoder(85);
    var jpgStream:ByteArray = jpgEncoder.encode(bmpData);

    var loader:URLLoader = new URLLoader();
        configureListeners(loader);

    var header:URLRequestHeader = new URLRequestHeader("Content-type", "application/octet-stream");
    var request:URLRequest = new URLRequest(ModelLocator.BASE_URL + ModelLocator.UPLOAD_URL + "?user=" + ModelLocator.getInstance().username);
    request.requestHeaders.push(header);
    request.method = URLRequestMethod.POST;
    request.data = jpgStream;
    loader.load(request);
}

请注意，变量是作为查询字符串的一部分传递的.您不能使用 URLVariables，正如一些人所建议的那样，因为 URLVariables 将存储在请求的 data 属性中，我们已经使用它来传递 byteArray.

Note that the variables are passed as part of the query string. You can't use URLVariables, as several people have suggested, as the URLVariables would be stored in the request's data property, which we are already using to pass the byteArray.
