The middleware must have below methods:
interface BpframeworkMiddleware {
/** name of middleware */
name: string,
/** web framework type. e.g. 'koa' **/
type: string,
/** initiator the middleware */
initiator: (app:any, bpApp:any)=>void,
/** The framework context finished, all objects of framework, e.g. FeignClient, start working. */
contextFinished?: (app:any, bpApp:any)=>void,
/** call before route */
beforeRoute?: (app:any, bpApp:any, request?:any)=>Promise<boolean>,
/** call after route */
afterRoute?: (app:any, bpApp:any)=>Promise<boolean>,
}initiator -> contextFinished -> beforeRoute -> afterRoute
Example:
export default {
name: 'test-middleware',
type: 'koa',
initiator(app, bpApp) {
},
async beforeRoute(ctx, bpApp, request): boolean {
// To interrupt process of follow-up .
return false;
},
async afterRoute(ctx, bpApp): boolean {
// To interrupt process of follow-up.
return false;
},
}
