Question

很奇怪。该代码在Chromium中运行良好 - 在授权（oauth2）之后，访问Google云端点以下载信息。但是一旦它被转换为js并在Chrome中打开，授权后，它就永远不会访问云端点（从Google应用引擎日志检查）。如果它在IE9中打开，即使授权页面也不会显示。任何帮助表示赞赏。

我已经使用了discovery_api_client_generator，效果很好。但是，默认情况下，它设置为不进行身份验证，因为库中的变量设置为false，并且无法从外部更改它。如果您在文件client_base.dart中手动编辑生成的库，则下面的browser_client.dart中的代码将执行＆＃39; right＆＃39;事情，这是称为认证。

if (makeAuthRequests && auth != null) {
  auth.authenticate(request).then((request) => request.send(body));
} else {
  request.send(body);
}

Dart2Js生成的代码无法访问Google云端点
