【问题描述】：

在 apollo federation 中是否有任何选项可以同时添加标头和上传到 buildService？ 我想要我的标头进行身份验证和上传以上传文件。 buildService 不支持返回对象。

const gateway = new ApolloGateway(
  buildService( name, url ) 
    return new RemoteGraphQLDataSource(
      url,
      willSendRequest( request, context :  request: any; context: any ) 
        request?.http?.headers?.set(
          "authorization",
          context.auth ? context.auth : ""
        );
        request?.http?.session?.set(
          "session",
          context.session ? context.session : ""
        );
        request?.http?.sessionStore?.set(
          "sessionStore",
          context.sessionStore ? context.sessionStore : ""
        );
      ,
    );
  ,
);

如何将upload file 也添加到我的 buildService？

【参考方案1】：

找到解决方案，如果您扩展 FileUploadDataSource 以某种方式工作：

import FileUploadDataSource from "@profusion/apollo-federation-upload";

class AuthenticationAndUpload extends FileUploadDataSource 
  willSendRequest(
    request,
    context,
  : 
    request: GraphQLRequest;
    context: any;
  ) 
    request?.http?.headers?.set(
      "authorization",
      context.auth ? context.auth : ""
    );
  


const gateway = new ApolloGateway(
  buildService( url ) 
    return new AuthenticationAndUpload( url );
  ,
);
