Question

我已经开始使用Google Developer's教程，了解如何构建Chrome扩展程序。（https://developer.chrome.com/extensions/getstarted）我按照指示操作，但弹出窗口不会生成任何照片。（描述，黄铜等都加载正常。）

起初我认为Flickr API密钥无效，但即使将密钥更新为有效密钥也不会做任何事情。我还尝试禁用所有其他扩展程序，以确保它不会发生冲突，并在新窗口中打开它。我还通过JSFiddle运行代码，看看是否有无效的东西。

有人可以填写我想要做的工作吗？（据我所知，它是一个认证令牌问题或缺乏认证令牌。）

编辑：

这是popup.js文件。我没有改变代码。这是从站点下载的原始文件。我避免发布整个文件，因为它相当长。（我禁用了所有扩展程序并试图运行实践扩展程序，它仍然给我一个空的弹出框。）

Answer 1

我想我可能会找到答案，这是来自flickr.com的消息：

已禁用无参数搜索。请改用flickr.photos.getRecent。

只需使用flickr.photos.getRecent，并删除不必要的参数即可。
