HTTP 链接

httpLink 是一个 终止链接，它通过 HTTP 将 tRPC 操作发送到 tRPC 过程。

httpLink 支持 POST 和 GET 请求。

使用

您可以导入并将 httpLink 添加到 links 数组，如下所示

client/index.ts
ts
import { createTRPCClient, httpLink } from '@trpc/client';
import type { AppRouter } from '../server';
const client = createTRPCClient<AppRouter>({
  links: [
    httpLink({
      url: 'http://localhost:3000',
      // transformer,
    }),
  ],
});

client/index.ts
ts
import { createTRPCClient, httpLink } from '@trpc/client';
import type { AppRouter } from '../server';
const client = createTRPCClient<AppRouter>({
  links: [
    httpLink({
      url: 'http://localhost:3000',
      // transformer,
    }),
  ],
});

httpLink 选项

httpLink 函数接受一个具有 HTTPLinkOptions 形状的选项对象。

ts
export interface HTTPLinkOptions {
  url: string;
  /**
   * Add ponyfill for fetch
   */
  fetch?: typeof fetch;
  /**
   * Add ponyfill for AbortController
   */
  AbortController?: typeof AbortController | null;
  /**
   * Data transformer
   * @link https://trpc.node.org.cn/docs/v11/data-transformers
   **/
  transformer?: DataTransformerOptions;
  /**
   * Headers to be set on outgoing requests or a callback that of said headers
   * @link https://trpc.node.org.cn/docs/v10/header
   */
  headers?:
    | HTTPHeaders
    | ((opts: { op: Operation }) => HTTPHeaders | Promise<HTTPHeaders>);
  /**
   * Send all requests as POSTS requests regardless of the procedure type
   * The server must separately allow overriding the method. See:
   * @link https://trpc.node.org.cn/docs/rpc
   */
  methodOverride?: 'POST';
}

ts
export interface HTTPLinkOptions {
  url: string;
  /**
   * Add ponyfill for fetch
   */
  fetch?: typeof fetch;
  /**
   * Add ponyfill for AbortController
   */
  AbortController?: typeof AbortController | null;
  /**
   * Data transformer
   * @link https://trpc.node.org.cn/docs/v11/data-transformers
   **/
  transformer?: DataTransformerOptions;
  /**
   * Headers to be set on outgoing requests or a callback that of said headers
   * @link https://trpc.node.org.cn/docs/v10/header
   */
  headers?:
    | HTTPHeaders
    | ((opts: { op: Operation }) => HTTPHeaders | Promise<HTTPHeaders>);
  /**
   * Send all requests as POSTS requests regardless of the procedure type
   * The server must separately allow overriding the method. See:
   * @link https://trpc.node.org.cn/docs/rpc
   */
  methodOverride?: 'POST';
}
