在android中使用http post发送一个Bitmap的字节数组？

ByteArrayOutputStream byteArrayOutputStream = new ByteArrayOutputStream();
bitmap.compress(Bitmap.CompressFormat.PNG, 100, byteArrayOutputStream);
byte[] byteArray = byteArrayOutputStream.toByteArray();

URL url = new URL("https://your-api-endpoint.com/upload");
HttpURLConnection connection = (HttpURLConnection) url.openConnection();
connection.setRequestMethod("POST");
connection.setDoOutput(true);
connection.setRequestProperty("Content-Type", "application/octet-stream");

OutputStream outputStream = connection.getOutputStream();
outputStream.write(byteArray);
outputStream.close();

int responseCode = connection.getResponseCode();
if (responseCode == HttpURLConnection.HTTP_OK) {
    // 处理响应
} else {
    // 处理错误
}
