Aws Cognito+Angular 7-如何同时创建用户并将用户分配给用户组

同时 . 当你必须创造一个可观察的东西时,这对我来说很好。但是当有必要创建一个可观察的对象来提出两个请求时,我就不工作了。我想我们需要用 forkJoin 或 flatMap . 我用角7所以RxJs 6.x。

createUser(user: User): Observable<User[]> {
    const _self = this;
    const cognitoidentityserviceprovider = new AWSCognito.CognitoIdentityServiceProvider({
      credentials: this.getCognitoCreds()
    });
    const params = {
      UserPoolId: this.poolData.UserPoolId,
      Username: user.username,
      DesiredDeliveryMediums: [ 'EMAIL' ],
      ForceAliasCreation: false,
      MessageAction: 'SUPPRESS',
      TemporaryPassword: '1234fooo*',
      UserAttributes: [
        {
          Name: 'email',
          Value: user.email
        }
      ]
    };
    return Observable.create(obs => {
      cognitoidentityserviceprovider.adminCreateUser(params, function(error, data) {
        if (error) {
          console.log(error);
          return Observable.throw(error || 'Server error');
        } else {
          console.log(data);
          //
          //
          // HERE user is create  :)
          // I want add to group here (see code down in this post) 
          //
          //
          return obs.next(data);
        }
      });
    });
  }

添加组码确定:

const p = {
            GroupName: 'admin',
            UserPoolId: _self.poolData.UserPoolId,
            Username: user.username
          };
          return Observable.create(o => {
            cognitoidentityserviceprovider.adminAddUserToGroup(p, function(err, d) {
              if (err) {
                console.log(err);
                return Observable.throw(err || 'Server error');
              } else {
                console.log(d);
                return o.next(d);
              }
            });
          });
