错误处理

import { HTTPException } from "hono/http-exception";

throw new HTTPException(401, { message: "自定义错误信息" });

如：

app.post("/auth", async (c, next) => {
  // 身份验证
  if (authorized === false) {
    throw new HTTPException(401, { message: "自定义错误信息" });
  }
  await next();
});

也可以自定义响应

const errorResponse = new Response("未经授权", {
  status: 401,
  headers: {
    Authenticate: 'error="invalid_token"',
  },
});

throw new HTTPException(401, { res: errorResponse });

全局响应

app.onError((err, c) => {
  if (err instanceof HTTPException) {
    // 获取自定义响应
    return err.getResponse();
  }
});
