我正在學習node.js，以便可以處理我的個人項目。我也試圖開始「真實」。事實上，我嘗試起來的第一個重要功能是登錄功能。出於某種原因，在URL中彈出?時無法正常工作。使用res.sendFile（）處理url中的查詢字符串
我在appServer.js代碼是一樣的東西：
var express = require('express');
var app = express();
var bodyParser = require('body-parser');
var session = require('client-sessions');
var users = require('./helpers/users.js'),
helpers = require('./helpers/helpers.js');
var fs = require('fs'),
path = require('path');
var https = require('https');
function handleIncomingRequest(req, res)
{
console.log("INCOMING REQUEST: " + req.method + " " + req.url);
console.log("req.url == " + req.url);
var questionMarkIndex = req.url.indexOf('?');
console.log("questionMarkIndex == " + questionMarkIndex);
var filename = req.url;
if (questionMarkIndex != -1) filename = req.url.substr(0, questionMarkIndex);
serveStaticFile(filename,
res);
//serveStaticFile(req.url, res);
}
app//.use(express.logger('dev'))
.use(bodyParser.urlencoded({ extended: true }))
.use(session({
cookieName: 'session',
secret: 'ckwtngqjqerrafourhpvi',
duration: 30 * 60 * 1000,
activeDuration: 15 * 60 * 1000,
httpOnly: true,
secure: true,
ephemeral: true
}))
.get("/YALApp/*",
requirePageLogin,
function(req, res)
{
handleIncomingRequest(req, res);
}
)
.get("/YALApp",
function (req, res) {
res.redirect('/YALApp/');
}
)
.post('/service/login', users.login)
.get("*",
function(req, res)
{
res.writeHead(404, { "Content-Type" : "application/json" });
res.end(JSON.stringify(helpers.makeError("file_not_found",
"The requested file cannot be accessed: " + req.url), null, '\t') + '\n');
}
);
app.listen(8080);
/*https.createServer(options, app).listen(8080, function()
{
console.log("server listening on port 8080");
});
*/
function serveStaticFile(file, res)
{
console.log("file == " + file);
var url = '/var/www/html' + file;
if (url.charAt(url.length - 1) == '/' || url.lastIndexOf('.') == -1)
{
console.log(res.sendFile);
res.sendFile(url + '/index.html');
return;
}
res.sendFile(url);
}
初始靜態頁面（網址：/YALApp/loginPage.html）負載就好了，但它的依賴不會（並因此頁面不能正常運行） 這裏是靜態頁面：
這裏發生的事情：

的努力結果？！？！？
我建議停止解析URL自己。 NodeJS帶有一個URL包，允許進行各種URL解析和操作。例如：'url.parse（req.url，true）'。想了解更多信息，請訪問https://nodejs.org/api/url.html – Dogoku
@Dogoku 不錯的想法，但它不適合我:( –
）您是否需要該軟件包？var url = require（'url'）; ''''''''NodeJS暴露了很少的全局變量，你必須要求大部分東西 – Dogoku
