需要理解爲什麼expressjs被重定向到index.html的

Question

我有以下的服務器上的文件，使用快遞：

var express = require('express'); 
var app  = express(); 
var port = process.env.PORT || 8080; 

app.listen(port); 
console.log('Listening on port: ' + port); 

// get an instance of router 
var router = express.Router(); 
app.use('/', router); 
app.use(express.static(__dirname + "/")); 

// route middle-ware that will happen on every request 
router.use(function(req, res, next) { 
    // log each request to the console 
    console.log(req.method, req.url + " logging all requests"); 
    // continue doing what we were doing and go to the route 
    next(); 
}); 

// home page route for port 8080, gets executed when entering localhost:8080 
// and redirects to index.html (correctly and as expected) 
router.get('/', function(req, res) { 
    console.log("routing from route") 
    res.redirect('index.html'); 
}); 

// This gets executed when my url is: http://localhost:8080/test 
// and redirects to index.html (the questions is why!? I thought 
// all the requests to root route would be caught by the router instance 

app.get('*', function(req, res){ 
    console.log('redirecting to index.html'); 
    res.redirect('/index.html');   
}); 

看看上面的代碼，我的意見，我不明白爲什麼

app.get('*', function(){...}) 

當URL爲 localhost:8080/index.html但在URL爲 localhost:8080/test
時，

不會被執行即使這是我所希望的行爲，但我不確定爲什麼這個行爲KS？
我沒有在根目錄中的「test.html」頁面。 的另一件事，在做的index.html加載其他腳本，所以我預計

app.get('*', function(){...})  

得到這樣的get請求執行過，因爲它應該是包羅萬象的，但事實並非如此。

app.use('/', router)是否意味着任何具有單個字符「/」的路由應由Router實例處理（只要不是靜態文件）？所以「http：localhost：8080」被解釋爲「http://localhost:8080/」？

我將不勝感激任何解釋。

Answer 1

這LINE-

app.use(express.static(__dirname + "/"));

將首先運行。它會看到index.html存在並靜態提供該文件。
