Question

有没有办法从服务包装器获取服务路径/路由？

这样的事情：

let myService = app.service('users');

myService.name === 'users'; // true

我正在尝试基于现有服务动态创建新服务，如下所示：

let services = [service1, service2, service3];

services.forEach(service=>{
    app.use(`somePrefix-${service.name}`, {get: get, find:find /*etc*/});
});

我需要服务的路径来注册新路径。

有两种方法可以做到这一点。首先，您已经回答过：使用setup方法并设置context.Users .Select(u => new UserViewModel { UserId = u.UserId, UserName = u.Name, UserEmail = u.Email, UserType = u.UserType.Value }).ToList();。

另一个是添加service mixin，只要注册了服务，就会调用它。
