如何返回不同类型的可观察值

发布于 2025-01-17 13:12:53 字数 1112 浏览 0 评论 0原文

我有一个可观察的方法，它返回一些数据，我需要从另一个可观察的方法订阅它，但我收到错误

public getSessionInfo(): Observable<UserInfo> {
   return this.getUserDetails().subscribe((data: any) => {
        return of({
            userId: data.UserID,
            tenantId: data.tenantID,
            launchDarklySecureModeHash: '',
            roles: [''],
            emailId: data.EmailID,
            tenantName: data.name,
            userName: data.UserName,
            pendoJWTToken: '',
            location: '/',
            displayLocation: ''
        })
    });
}

我收到错误，订阅缺少 UserInfo 的 Observable 类型的以下属性，但是代码部分

return of({
            userId: data.UserID,
            tenantId: data.tenantID,
            launchDarklySecureModeHash: '',
            roles: [''],
            emailId: data.EmailID,
            tenantName: data.name,
            userName: data.UserName,
            pendoJWTToken: '',
            location: '/',
            displayLocation: ''
        })

的类型与是可观察的 UserInfo 但我无法解决这个问题。请有人建议解决方案，并记下我无法对 getSessionInfo 方法的类型进行任何更改，因为它是覆盖方法。

提前致谢。

I have a observable method which is return some data I need to subscribe this from another observable method but I am getting error

public getSessionInfo(): Observable<UserInfo> {
   return this.getUserDetails().subscribe((data: any) => {
        return of({
            userId: data.UserID,
            tenantId: data.tenantID,
            launchDarklySecureModeHash: '',
            roles: [''],
            emailId: data.EmailID,
            tenantName: data.name,
            userName: data.UserName,
            pendoJWTToken: '',
            location: '/',
            displayLocation: ''
        })
    });
}

I am getting error that subscription is missing the following properties of type Observable of UserInfo, however the code section

return of({
            userId: data.UserID,
            tenantId: data.tenantID,
            launchDarklySecureModeHash: '',
            roles: [''],
            emailId: data.EmailID,
            tenantName: data.name,
            userName: data.UserName,
            pendoJWTToken: '',
            location: '/',
            displayLocation: ''
        })

is of same type which is Observable of UserInfo but I am not able to fix this.
Please someone suggest the solution by noted down that I can't make any change in type of getSessionInfo methis as it is override method.

Thanks in advance.

您返回的是 Subscription，而不是返回 Observable。更新包括 switchMap 的代码片段。

public getSessionInfo(): Observable<UserInfo> {
  return this.getUserDetails().pipe(
    switchMap((data: any) => of({
      userId: data.UserID,
      tenantId: data.tenantID,
      launchDarklySecureModeHash: '',
      roles: [''],
      emailId: data.EmailID,
      tenantName: data.name,
      userName: data.UserName,
      pendoJWTToken: '',
      location: '/',
      displayLocation: ''
    }))
  );
}

You are returning a Subscription instead of returning an Observable. Update the snippet including switchMap.

public getSessionInfo(): Observable<UserInfo> {
  return this.getUserDetails().pipe(
    switchMap((data: any) => of({
      userId: data.UserID,
      tenantId: data.tenantID,
      launchDarklySecureModeHash: '',
      roles: [''],
      emailId: data.EmailID,
      tenantName: data.name,
      userName: data.UserName,
      pendoJWTToken: '',
      location: '/',
      displayLocation: ''
    }))
  );
}
