使用javascript处理通用api中的缺失属性

Question

I am working with a general purpose REST api that happens to exclude properties where the values are null (Spring Jackson @JsonInclude(Include.NON_NULL))

Since I am just using Javascript (vue.js & axios) and generally not privy to what may or maynot be returned, what is the best way to handle missing properties in the axios

response.data.expectedProprtyIsNotThere

in a general way so that is can be applied to all response objects without any additional code or duplication? I think I might be ok with have a default value of null or empty string.

I am not using any sdk and using the response data object directly.

Answer 1

You could create a default response

var default = {...};

And before you use your response you insert the missing properties using Object.assign() :

response = Object.assign({},default,response);
