如何使用JsonObject将位图从安卓系统发送到WCF服务

Bitmap bitmap = ...; // 获取位图对象
ByteArrayOutputStream stream = new ByteArrayOutputStream();
bitmap.compress(Bitmap.CompressFormat.JPEG, 100, stream);
byte[] bitmapBytes = stream.toByteArray();

JsonObject jsonObject = new JsonObject();
jsonObject.put("bitmap", Base64.encodeToString(bitmapBytes, Base64.DEFAULT));

URL url = new URL("http://your-wcf-service-url");
HttpURLConnection connection = (HttpURLConnection) url.openConnection();
connection.setRequestMethod("POST");
connection.setRequestProperty("Content-Type", "application/json");
connection.setDoOutput(true);
OutputStream outputStream = connection.getOutputStream();
outputStream.write(jsonObject.toString().getBytes("UTF-8"));
outputStream.close();

int responseCode = connection.getResponseCode();
if (responseCode == HttpURLConnection.HTTP_OK) {
    // 请求成功
    // 处理WCF服务的响应
} else {
    // 请求失败
}
