如何发送图像中的ImageView的一个PHP服务器？ [英] how to send the image in an ImageView to a php server?

问题描述

有一次，我在ImageView的有一个形象，我怎样才能将图像发送到Web服务器的最简单的方法可能吗？

once i have an image in an ImageView, how can i send the image to a web server in the simplest way possible??

我用这让从画廊的图片：

I got the image from the gallery using this :

protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    if (requestCode == REQUEST_CODE && resultCode == Activity.RESULT_OK)
        try {
            // We need to recyle unused bitmaps
            if (bitmap != null) {
                bitmap.recycle();
            }
            InputStream stream = getContentResolver().openInputStream(
                    data.getData());
            bitmap = BitmapFactory.decodeStream(stream);
            stream.close();
            imageView.setImageBitmap(bitmap);
        } catch (FileNotFoundException e) {
            e.printStackTrace();
        } catch (IOException e) {
            e.printStackTrace();
        }
    super.onActivityResult(requestCode, resultCode, data);
}

推荐答案

我没有用PHP做到了这一点，但使用.NET期运用的base64字符串发送的图像。

i haven't done this with PHP but sent the image with .NET useing base64 string.

图像转换成你的base64和你的服务器上发送此字符串。您的服务器将在此的base64转换为原始图像

convert you image into base64 and send this string on your server. your server will convert this base64 to original image

到图像转换成字节[]尝试以下code

to convert image into byte[] try following code

private void setPhoto(Bitmap bitmapm) {
        try {
            ByteArrayOutputStream baos = new ByteArrayOutputStream();
            bitmapm.compress(Bitmap.CompressFormat.JPEG, 100, baos); 

            byte[] byteArrayImage = baos.toByteArray();
            String imagebase64string = Base64.encodeToString(byteArrayImage,Base64.DEFAULT);
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
