问题描述
account.effect.ts 文件
fetchUserInfo$ = createEffecct(() =>
this.actions$.pipe(
ofType(AccountActions._fetchAccountInfo),switchMap(({accountNumber}) =>
this.accServvice.getAccInfo(accountNum).pipe(
map((accountInfo: AccType) =>
AccountActions.loadUserInfoSuccess({data: accountInfo}),),catchError((error) =>
of(AccountActions.userDataFails({error}))
)
)
)
)
)
在上面的文件中,我导入了选择器,您可以通过以下方式访问它 this.store.select(FromAcc.getSelectedAccInfo)。我想访问选择器值 FromAcc.getSelectedAccInfo 并添加一个我将从服务接收的值,然后将其发送到操作 AccountActions.loadUserInfoSuccess。 我对 ngrx 很陌生。请告诉我该怎么做。
解决方法
您可以尝试以下解决方案
fetchUserInfo$ = createEffecct(() =>
this.actions$.pipe(
ofType(AccountActions._fetchAccountInfo),// below 2 lines updated
withLatestFrom(this.store.select(FromAcc.getSelectedAccInfo)),switchMap(([accountNumber,selectedAccInfo]) =>
this.accServvice.getAccInfo(accountNum).pipe(
map(([accountInfo: AccType,) =>
AccountActions.loadUserInfoSuccess({data: accountInfo}),),catchError((error) =>
of(AccountActions.userDataFails({error}))
)
)
)
)
)
