I am seeing the following error when I run the web-app on a localhost: TypeError: Cannot set property '$save' of undefined at module.factory.config.factory.provider.$get (http://127.0.0.1:62557/client/js/lb-services.js:2409:34)

此外，我不是运行 $http 脚本，因为我已经安装并正在使用 lb-services 进行调用和 return 请求。问题在于我无法向数据库发送请求或从数据库中提取数据。我也是运行节点。

非常感谢任何帮助或见解！！

Answer 1

您在 https://github.com/strongloop/loopback-example-angular 看到我的示例了吗？如果您仍然运行遇到问题，请告诉我。

Answer 2

我知道哪里出了问题！

我的 lbservices.js 文件使用基数 URL 的 '/api' 而它需要是 'http://localhost:3000/api'。

感谢您的帮助！！

Why won't my database populate with angularjs, angular-ui-router and looback api?
