首先，确保您的API Gateway正在使用基于令牌的身份验证。如果需要，您可以使用AWS Cognito将用户身份验证与API Gateway集成。

其次，确保您的Amplify配置正确设置，包括设置API Gateway终端节点和授权类型。例如：

Amplify.configure({
  ...
  API: {
    endpoints: [
      {
        name: "myEndpoint",
        endpoint: "https://my-api-gateway-url.execute-api.us-east-1.amazonaws.com",
        region: "us-east-1",
        custom_header: async () => {
          return {
            Authorization: `Bearer ${(await Auth.currentSession()).getIdToken().getJwtToken()}`,
          };
        },
      },
    ],
  },
});

在get请求中使用fetchAuthSession：

import { API, Auth } from 'aws-amplify';

const makeAuthedRequest = async () => {
  const session = await Auth.currentSession();
  const apiKey = 'YOUR_API_KEY';

  const apiName = 'myEndpoint';
  const path = '/myresource';
  const init = {
    headers: {
      'x-api-key': apiKey,
    }
  }

  const apiResponse = await API.get(apiName, path, init);
  return apiResponse;
}
