java - 上传文件 - DocumentList.java 示例给出“需要授权”错误

Question

我正在尝试将文件从我的桌面上传到谷歌驱动器。我在 Google 提供的示例中给出了CLIENT_IDand 。当我作为 java 应用程序运行时，出现以下错误：CLIENT_SECRETDocumentList.java

return service.insert(buildUrl(URL_DEFAULT + URL_DOCLIST_FEED), newDocument);

代码：

oauthParameters.setOAuthConsumerKey(CLIENT_ID);
oauthParameters.setOAuthConsumerSecret(CLIENT_SECRET);    
oauthParameters.setScope("https://docs.google.com/feeds/");
DocsService service = new DocsService("wise");

错误：
