默认情况下，tRPC 不会在组件卸载时取消请求。如需启用此行为，可在配置回调中设置 abortOnUnmount 参数。

全局设置

client.ts
ts
import { httpBatchLink } from '@trpc/client';
import { createTRPCNext } from '@trpc/next';
import type { AppRouter } from './server/routers/_app';
 
export const trpc = createTRPCNext<AppRouter>({
  config() {
    return {
      links: [
        httpBatchLink({
          url: '/api/trpc',
        }),
      ],
      abortOnUnmount: true,
    };
  },
});

client.ts
ts
import { httpBatchLink } from '@trpc/client';
import { createTRPCNext } from '@trpc/next';
import type { AppRouter } from './server/routers/_app';
 
export const trpc = createTRPCNext<AppRouter>({
  config() {
    return {
      links: [
        httpBatchLink({
          url: '/api/trpc',
        }),
      ],
      abortOnUnmount: true,
    };
  },
});

按请求设置

您也可以在请求级别覆盖此行为。

client.ts
tsx
import { trpc } from './utils/trpc';
import { useRouter } from 'next/router';
 
function PostViewPage() {
  const id = useRouter().query.id as string;
  const postQuery = trpc.post.byId.useQuery({ id }, { trpc: { abortOnUnmount: true } });
 
  return null;
}

client.ts
tsx
import { trpc } from './utils/trpc';
import { useRouter } from 'next/router';
 
function PostViewPage() {
  const id = useRouter().query.id as string;
  const postQuery = trpc.post.byId.useQuery({ id }, { trpc: { abortOnUnmount: true } });
 
  return null;
}
