500 ResolutionError：键'authentication.userProfileFactory'未绑定到上下文RestServer中的任何值

问题描述

    export const USER_PROFILE_FACTORY = BindingKey.create<
    UserProfileFactory<any>
    >('authentication.userProfileFactory');

这是未绑定上下文的用户配置文件工厂。我如何与上下文绑定。

    this.controller(UserController);
    this.controller(TodoController);

    this.isBound('authentication.userProfileFactory');
    this.bind('services.authentication.basic.user.service.binding').toClass(
      BasicAuthenticationUserService,);
    //this.repository(UserRepository);
    server                                            //error here..
   .bind(AuthenticationBindings.USER_PROFILE_FACTORY) // error here..
   .to(myUserProfileFactory);                         // error here..
    this.bind('authentication.user.repo').toClass(UserRepository);
    //this.server.bind(AuthenticationBindings.USER_PROFILE_FACTORY);
    //this.bind('authentication.userProfileFactory').toProvider;
    // Set up the custom sequence and stratergy
    this.sequence(MyAuthenticationSequence);
    this.component(AuthenticationComponent);
    registerauthenticationStrategy(this,BasicAuthenticationStrategy);

    // Set up default home page
    this.static('/',path.join(__dirname,'../public'));

    this.component(RestExplorerComponent);

    this.projectRoot = __dirname;
    // Customize @loopback/boot Booter Conventions here
    this.bootOptions = {
      controllers: {
        // Customize ControllerBooter Conventions here
        dirs: ['controllers'],extensions: ['.controller.js'],nested: true,},};
    this.setupLogging();
  }

  private setupLogging() {
    // Register `morgan` express middleware
    // Create a middleware factory wrapper for `morgan(format,options)`
    const morganFactory = (config?: morgan.Options<Request,Response>) => {
      this.debug('Morgan configuration',config);
      return morgan('combined',config);
    };

    // Print out logs using `debug`
    const defaultConfig: morgan.Options<Request,Response> = {
      stream: {
        write: str => {
          this._debug(str);
        },};
    this.expressMiddleware(morganFactory,defaultConfig,{
      injectConfiguration: 'watch',key: 'middleware.morgan',});
  }
}

application.tx file i bind userservice and userrepository but how can i bound the user profile factory. if  try it's give error.

服务器 .bind（AuthenticationBindings.USER_PROFILE_FACTORY） .to（myUserProfileFactory）;

这种情况表明它不存在！
