在中断过程调用方面，tRPC 遵循行业标准。你只需将 AbortSignal 传递给查询或变更选项，若需取消请求，调用 AbortController 实例的 abort 方法即可。

utils.ts
ts
// @filename: server.ts
import { createTRPCProxyClient, httpBatchLink } from '@trpc/client';
import type { AppRouter } from 'server.ts';
 
const proxy = createTRPCProxyClient<AppRouter>({
  links: [
    httpBatchLink({
      url: 'http://localhost:3000/trpc',
    }),
  ],
});
 
// 1. Create an AbortController instance - this is a standard javascript API
const ac = new AbortController();
 
// 2. Pass the signal to a query or mutation
const query = proxy.userById.query('id_bilbo', { signal: ac.signal });
 
// 3. Cancel the request if needed
ac.abort();
