typescript - NestJS 从守卫中抛出 http 异常（导出为库模块）

问题描述

我正在制作一个 Nestjs 库，其中包含一个守卫作为模块的一部分，

我尝试从守卫中抛出 http 错误，但是上下文在控制器中丢失了，它只会抛出 500。

如果我将库作为源代码而不是 dist 构建导入，它工作正常。

@Injectable()
export class SignedUrlGuard implements CanActivate {
    constructor(
        private readonly signedUrlService: SignedUrlService,
    ) { }

    canActivate(
        context: ExecutionContext,
    ): boolean | Promise<boolean> | Observable<boolean> {
        const request = context.switchToHttp().getRequest();
        return this.validateRequest(request, request.query);
    }

    private validateRequest(request: Request, query: Record<string, string>): boolean {
        try {
            return this.signedUrlService.isSignatureValid(request, query)
        } catch (error) {
            throw new ForbiddenException('Invalid url ,with custom error message')
        }
    }
}

解决方案

通过基于文件的系统安装 npm 将不起作用

解决这个问题试试

npm 包

然后从 tgz 文件安装
