我正在构建一个Web应用程序,其中包含多个页面。然而,这些页面中的每一个都具有多个视图。最初的设计是将每个页面设置为SPA,并从Node.js后端提供index.html
,并让React.js处理所有视图路由。
事实证明这比我想象的要复杂得多。这是问题所在。
Node.js路由(摘录):
router.get("/", function(request, response){
response.sendFile("/index.html", {
root: __dirname + "/../client/pages/home/"
});
});
然后在index.html
(摘录)中:
<html>
<head>
<title>New Website</title>
</head>
<body>
<h1>Welcome to my website..</h1>
<div id="App">
</div>
<script src="index.js"></script>
</body>
</html>
index.js
未包括在内。当浏览器尝试包含index.js
时,它正在从Node.js服务器请求路由www.example.com/index.js
,这显然没有设置,所以我收到Cannot GET /index.js
响应。
每个SPA都在index.html
和index.js
的各个文件夹中。目前,不能创建包含所有js文件的公用文件夹。
=============================================== ===========================
clientController.js
module.exports = function(app){
router.get("/", function(request, response){
app.use("/", express.static(__dirname + "/../client/pages/page1/"));
response.sendFile("index.html", {
root: __dirname + "/../client/pages/page1/"
});
});
router.get("/page2/*", function(request, response){
app.use("/", express.static(__dirname + "/../client/pages/page2/"));
response.sendFile("index.html", {
root: __dirname + "/../client/pages/page2/"
});
});
return router;
};
server.js
var routes = require("controllers/clientController.js");
app.use("/", routes);
接受的答案,我必须在sendFile()
行添加以防止请求挂起。这样可以确定响应并允许在HTML文件中包含文件包含的正确路径。

如ExpressJs documentation中所述,您必须使用express.static(root, [options])
来创建管理您网站的中间件。这是Express中唯一的内置中间件功能。
在你必须初始化表达app之前:
var express = require('express');
var app = express();
然后开始添加中间件:
注意:您可以添加多个中间件,并按顺序链接它们。换句话说,您可以在网站中间件之前添加标头处理程序。
app.use(function (req, res, next) {
/* you can also handle https redirection */
// if (req.protocol != "https") {
// res.writeHead(301, {"Location": "https://" + req.headers['host'] + req.url});
// res.end();
// return;
// }
// here you can config you response headers
res.header("Access-Control-Allow-Origin", "*");
res.header("Access-Control-Allow-Headers", "Origin, X-Requested-With, Content-Type, Accept");
res.header('Access-Control-Allow-Methods', 'GET, POST, PUT, DELETE, OPTIONS');
next(); // this will pass the request to the next middleware
});
要使用ExpressJs创建中间件网站,您必须将express.static
与您的相关网站文件夹一起使用,并将您的默认页面命名为index.html
app.use("/", express.static('PATH_TO_WEBSITE FOLDER'));
var express = require('express');
var app = express();
app.use(function (req, res, next) {
/* you can also handle https redirection */
// if (req.protocol != "https") {
// res.writeHead(301, {"Location": "https://" + req.headers['host'] + req.url});
// res.end();
// return;
// }
// here you can config you response headers
res.header("Access-Control-Allow-Origin", "*");
res.header("Access-Control-Allow-Headers", "Origin, X-Requested-With, Content-Type, Accept");
res.header('Access-Control-Allow-Methods', 'GET, POST, PUT, DELETE, OPTIONS');
next(); // this will pass the request to the next middleware
});
app.use("/", express.static('PATH_TO_WEBSITE FOLDER'));
var httpServer = http.createServer(app);
httpServer.listen(80, "HERE_PUT_YOUR_DOMAIN", function () {
console.log('HTTP: express-example running on port ' + 80 + '.');
});

您的目录将被视为静态。您不需要创建单独的目录或定义单独的路径。
router.use(express.static( __dirname + "/../client/pages/home/"));
