获得"Cannot read property 'parameters' of null"招摇的规格

Question

我有下面的JSON，它是我自己从代码中生成的。我基本上是在编写代码来为UI生成swagger规范。我正在写一个新的，因为我仍然使用play 1.3，而swagger模块已经有一段时间没有更新了。然而，我从代码生成器中得到了这个JSON，但UI挂在"获取资源列表：http://localhost:9100/resources.json；请稍候。javascript控制台显示错误"Getting"Cannot read property‘parameters’of null"for swagger spec"。我不知道该怎么办，如有任何帮助，将不胜感激。

Answer 1

问题在于null值。它们需要被禁用——null不同于"不存在"。也就是说，我认为您需要将映射器配置为不写null。

Answer 2

我遇到了这个问题，结果发现它与我的.NET web api应用程序中的JSON格式化程序有关。我能够通过将这一行添加到BootStrap类Configure方法中来解决它。

config.Formatters.Clear();
