Javascript 如何在GraphQL/AWS Amplify中启用前端的CORS模式？

如何对AWS Amplify的GraphQL执行相同的操作

fetch（'https://trusted-api.co.jp', {
模式：“cors”
});

我既没有找到如何做的文档，也没有找到提到cors的源代码

参考文献 可以按如下方式调用常规graphQL操作：

import AWSAmplifyAPI, { graphqlOperation as graphQL_Operation, GraphQLResult } from "@aws-amplify/api";
import Observable from "zen-observable";

export default class DataBaseService {

  public static async sendRequestAndExtractDataFromResponse(
      graphQL_RawRequest: string,
      requestVariables?: object
  ): Promise<unknown> {

    const serverRawResponse: GraphQLResult | Observable<unknown> =
        await AWSAmplifyAPI.graphql(graphQL_Operation(graphQL_RawRequest, requestVariables));
   // ...
  }
}

import AWSAmplifyAPI，{graphqlOperation as graphQL_Operation，GraphQLResult}来自“@aws-amplify/api”；
从“zen Observable”导入Observable；
导出默认类数据库服务{
公共静态异步sendRequestAndExtractDataFromResponse(
graphQL_RawRequest:字符串，
请求变量？：对象
)：承诺{
const serverRawResponse:GraphQLResult |可观察=
等待AWSAmplifyAPI.graphql（graphql_操作（graphql_RawRequest，requestVariables））；
// ...
}
}

您需要在服务器端对此进行配置，因此服务器端需要批准此“CORS”问题

从技术上讲，放大lambda函数将添加类似于以下内容的代码：

exports.handler = async (event) => {
  const response = {
    statusCode: 200,
    //  Uncomment below to enable CORS requests
    headers: {
      "Access-Control-Allow-Origin": "*",
    },

    //   headers: {
    //     "Access-Control-Allow-Headers" : "Content-Type",
    //     "Access-Control-Allow-Origin": "https://www.example.com",
    //     "Access-Control-Allow-Methods": "OPTIONS,POST,GET"
    // },
    body: JSON.stringify("Hello from Lambda!"),
  };
  return response;
};

谢谢你的回答！
