java - 尝试上传文件导致 403 - notAllowed 响应

Question

我正在尝试使用 Microsoft REST API 将文件上传到 OneDrive。我正在将访问令牌传递给从 Azure AD 服务获得的请求：

URL urlTest = new URL("https://graph.microsoft.com/v1.0/me/drive/root:/TestFolder/RaviPdf.pdf:/content");
LOGGER.info("url1  : "+urlTest );

HttpURLConnection httpConn = (HttpURLConnection) urlTest.openConnection();
LOGGER.info("conn1  : "+httpConn );
httpConn.setDoOutput(true);
httpConn.setRequestMethod("PUT");
httpConn.setRequestProperty("Authorization", "Bearer " + accessToken);
httpConn.setRequestProperty("Accept","application/json");
httpConn.setRequestProperty("Content-Type", "application/x-www-form-urlencoded"); 
httpConn.setRequestProperty("charset","UTF-8");
httpConn.setRequestProperty("Content-Length",Integer.toString(100));

OutputStream os = httpConn.getOutputStream();
os.write(bArray);
os.close();  //don't forget to close the OutputStream
httpConn.connect();
httpResponseCode = httpConn.getResponseCode();
LOGGER.info("httpResponseCode "+httpResponseCode );
//here just printing error stream result 
LOGGER.info("httpConn.getErrorStream())"+httpConn.getErrorStream());

作为回应，我收到此错误：

    }
  }
}
