调用Express NodeJS中其他路由中已定义的路由 [英] Calling already defined routes in other routes in Express NodeJS
问题描述
app.get（/ firstService /：query，function（req，res） {
// trivial example
var html =< html>< body>< / body>< / html>;
res.end（html）
}）;
如何从快递中重用该路由？
app.get（/ secondService /：query，function（req，res）{
var data = app.call（/ firstService /+ query ）;
//使用数据
res.end（data）;
}执行某些操作;
我在API文档中找不到任何东西，宁可不使用其他库，如请求因为这似乎是坏蛋。我试图让我的应用程序尽可能模块化。想想？
谢谢
另一个功能是把它放在一个共享的位置，然后从那里去？
var queryHandler = require（'special_query_handler'）;
//包含一个名为firstService（req，res）的方法;
app.get（'/ firstService /：query'，queryHandler.firstService）;
//第二个app
app.get（'/ secondService /：query'，queryHandler.firstService）;
老实说，这个整个业务将回调嵌套在应用程序之内。 get（...）并不是一个很好的做法。你最终得到一个包含所有核心代码的巨型文件。
你真正想要的是一个填充有的文件app.get（）和 app.post（）所有回调处理程序的语句生活在不同的更好的组织文件中。
I am writing a web app in node.js using Express. I have defined a route as follows:
app.get("/firstService/:query", function(req,res){
//trivial example
var html = "<html><body></body></html>";
res.end(html)
});
How do I reuse that route from within express?
app.get("/secondService/:query", function(req,res){
var data = app.call("/firstService/"+query);
//do something with the data
res.end(data);
});
I couldn't find anything in the API documentation and would rather not use another library like "request" because that seems kludgey. I am trying to keep my app as modular as possible. Thoughts?
Thanks
Can you simply break this out into another function, put it in a shared spot and go from there?
var queryHandler = require('special_query_handler');
// contains a method called firstService(req, res);
app.get('/firstService/:query', queryHandler.firstService);
// second app
app.get('/secondService/:query', queryHandler.firstService);
Honestly, this whole business of nesting the call back inside of the app.get(...) is not really a great practice. You end up with a giant file containing all of the core code.
What you really want is a file filled with app.get() and app.post() statements with all of the callback handlers living in different, better organized files.
