在导出函数的命名空间中使用自定义类型
Use Custom types in a namespace that exports a function
我喜欢为 https://github.com/LionC/express-basic-auth
写一个 index.d.ts 文件
但我不知何故陷入了如何在选项对象中声明回调类型的问题。
declare module "express-basic-auth" {
import {Handler, Request} from "express";
function ExpressBasicAuthorizer(username: string, password: string): boolean;
function ExpressBasicAuthResponseHandler(req: Request): string|object;
interface ExpressBasicAuthUsers {
[username: string]: string;
}
interface ExpressBasicAuthOptions {
challenge?: boolean;
users?: ExpressBasicAuthUsers; // does not only allow string:string but other ex. string: number too
authorizer?: ExpressBasicAuthorizer; // *does not work*
authorizeAsync?: boolean;
unauthorizedResponse?: ExpressBasicAuthResponseHandler|string|object; // *does not work*
realm?: ExpressBasicAuthResponseHandler|string; // *does not work*
}
function expressBasicAuth(options?:ExpressBasicAuthOptions): Handler;
export = expressBasicAuth;
}
我得到:错误 TS2304:找不到名称 'ExpressBasicAuthorizer'
我如何声明 ExpressBasicAuthorizer 和 ExpressBasicAuthResponseHandler 以使其工作?
本例中的 ExpressBasicAuthorizer
和 ExpressBasicAuthResponseHandler
需要声明为 "type" 而不是 "function"。试试这个:
declare module "express-basic-auth" {
import { Handler, Request } from "express";
type ExpressBasicAuthorizer = (username: string, password: string) => boolean;
type ExpressBasicAuthResponseHandler = (req: Request) => string | object;
interface ExpressBasicAuthUsers {
[username: string]: string | number;
}
interface ExpressBasicAuthOptions {
challenge?: boolean;
users?: ExpressBasicAuthUsers;
authorizer?: ExpressBasicAuthorizer;
authorizeAsync?: boolean;
unauthorizedResponse?: ExpressBasicAuthResponseHandler | string | object;
realm?: ExpressBasicAuthResponseHandler | string;
}
function expressBasicAuth(options?: ExpressBasicAuthOptions): Handler;
export = expressBasicAuth;
}
