Node.js Express 嵌套资源

Question

我想像下面这样嵌套资源。

/// fileA.js
app.use('/dashboards/:dashboard_id/teams', teams);
[...]

///teams.js
router.get('/', function(req, res, next) {
[...]
}

但我无法在 teams 中获取 req.params["dashboard_id"] 参数，因为它似乎已被参数值替换。我试图通过调用中间函数并将参数传递到某处来解决问题，但我不知道在哪里......你有答案吗？谢谢，佛朗哥

Answer 1

您可以尝试这个解决方案:

//declare a function that will pass primary router's params to the request
var passPrimaryParams = function(req, res, next) {
    req.primaryParams = req.params;
    next();
}

/// fileA.js
app.use('/dashboards/:dashboard_id/teams', passPrimaryParams);
app.use('/dashboards/:dashboard_id/teams', teams);

///teams.js
router.get('/', function(req, res, next) {
    var dashboardId = req.primaryParams['dashboard_id'];  //should work now
    //here you may also use req.params -- current router's params
}
