Question

我正在尝试扩展 ISampleB 接口并省略其中的几个值，如下所示。我不知道我是否做错了什么

export interface ISampleA extends Omit<ISampleB, 'fieldA' | 'fieldB' | 'fieldC' | 'fieldD' | 'fieldE'> {
    fieldB?: string
    fieldA?: string
    fieldC?: string
    fieldD: number
    fieldE?: number
}

我的 swagger 生成器抛出如下错误

There was a problem resolving type of 'ISampleA'.

ode_modules/typescript-rest-swagger/dist/metadata/methodGenerator.js:83
                throw new Error("Error generate parameter method: '" + controllerId.text + "." + methodId.text + "' argument: " + parameterId.text + " " + e);
Error: Error generate parameter method: 'abc' argument: fields Error: No type found for Omit

Answer 1

尝试使用 Exclude<ISampleB, 'fieldA' | 'fieldB' | 'fieldC' | 'fieldD' | 'fieldE'>
