Google+ Domains API 404 Not Found 错误

Question

我正在尝试使用 Google+ Domains API 运行 Java 快速入门并检索 404 Not found 错误，但我不知道为什么会发生这种情况。我需要这个 api 来为客户预填充圈子。

快速入门指南链接：https://developers.google.com/+/domains/quickstart/java

我按照说明进行操作并且能够授权，但是当我想使用 API 做某事时，我会立即收到 404 Not Found。

由于授权已经完成，我希望使用带有私钥文件的服务帐户正确配置 API 访问。我正在使用域范围的委派并代表 userx@example.com。

有人知道我为什么会收到 404 Not Found 吗？我在企业帐户的免费测试域上运行此脚本。

Answer 1

1. 您能否检查一下您是否已在开发者控制台中启用了 Google+ Domains API。

2. 您能否确保您拥有来自 GitHub 的最新版本的快速入门 - 将 API 从 plus/v1domains 重命名为 plusDomains/v1 进行了更改，如果您有旧版本，这可能会影响您.

3. 您能否检查您正在测试的域是否启用了 Google+

4. 最后，您能否在问题中包含有关请求和响应的更多详细信息 - 如果您可以将它们注销并包含，那可能会有所帮助！
