检查设置存储库中的用户角色（typescript，aurelia）

Question

我正在进行授权导航。我做了这样的事

run(navigationInstruction: NavigationInstruction, next: Next) : Promise<any> {

    let requiredRoles = navigationInstruction.getAllInstructions()
                        .map(i => i.config.settings.roles)[0];

    toastr.success('TEST1');

    let isUserInRole = requiredRoles?   
        requiredRoles.some(r => r === this.userIdentity.role) : true;

    toastr.success('TEST2');//LINE IT`S NOT EXECUTED

    return isUserInRole? next() : next.cancel(new Redirect('users/login'));    
}

requiredRoles - 我已经检查了它并且它返回了我的价值

成行r => r === this.userIdentity.role在我的视觉代码中我有消息：Parameter 'r' implicitly has an 'any' type, but a better type may be inferred from usage.ts(7044)

Answer 1

我想你可以做的是将.roles)[0]转换为字符串（我想从你的代码的外观）

run(navigationInstruction: NavigationInstruction, next: Next) : Promise<any> {

    let requiredRoles = navigationInstruction.getAllInstructions()
                        .map(i => i.config.settings.roles)[0] as string;
  ...  
}

编辑：如果角色是一个字符串数组，那么你的代码应该是这样的

run(navigationInstruction: NavigationInstruction, next: Next) : Promise<any> {

    let requiredRoles = navigationInstruction.getAllInstructions()
                        .map(i => i.config.settings.roles)[0] as string[];
  ...  
}

这样做应该会使问题消失。
