您可以使用HttpFileUploadManager上传文件：

  try {
        HttpFileUploadManager httpFileUploadManager = XmppConnection.getInstance().getHttpFileUploadManager();
        XmppConnection.getInstance().discoverHttpService();
        final Slot slot = httpFileUploadManager.requestSlot(file.getName(), file.length(), null,
                JidCreate.domainBareFrom(Globals.getHttpUploadDomain()));

        httpFileUploadManager.uploadFile(file, slot, (uploadedBytes, totalBytes) -> {
            Log.d("totalBytes", ">>>" + totalBytes);
            Log.d("uploadedBytes", ">>>" + uploadedBytes);
            if (totalBytes == uploadedBytes) {
               //handle upload success (Send Message with the url in the body? the url is in slot.getGetUrl().toString();)
            }
        });

    } catch (Exception e) {
        e.printSackTrace();
       //handle failure
    }
