有没有办法在Hapi中为每条路线定义要返回的状态代码？
例如，
routes.js
server.route(routes);
server.js
responseCode在用户控制器中，我希望能够阅读class Resource {
constructor() {}
async request(handler, request, reply) {
try {
const response = await handler;
const statusCode = request.custom.responseCode; // how?
reply(response).code(statusCode);
} catch(error) {
reply(error);
}
}
}
class User extends Resource {
constructor(props) {
super(props);
}
list(request, reply) {
const getUsers = UserController.list();
super.request(getUsers, request, reply);
}
}
之类的内容：

我认为你的处理程序应该返回带有所需状态代码的响应。通过这种方式，您将能够根据业务逻辑设置代码（例如，如果新用户已存在于数据库中，则为代码409）。您可以通过简单地将响应包装在{data，statusCode}对象中来实现。
示例：
item = soup.find("tr").find_next_sibling().find('td').text
之后，您将能够访问该statusCode：
const response = { data: users, statusCode: 200 }
return response;
看起来太简单了，但实际上并不需要过度设计。
