使用带有nodeJS和Express的AngularJS html5mode

标签: javascript node.js angularjs express

我正在使用带有Express的nodeJS服务器来为我的AngularJS应用程序提供服务。当我使用angularJS默认路由(hashbangs)时,这一切都正常,但现在我正在尝试激活html5模式。

我正在激活html5mode:

$locationProvider.html5Mode(true).hashPrefix('!');

这就是我的nodeJS app.js文件的样子:

var path     = require('path'),
    express  = require('express'),
    app      = express(),
    routes   = require(path.join(__dirname, 'routes'));

app.configure(function() {
    app.use(express.logger('dev'));
    app.use(express.compress());
    app.use(express.methodOverride());
    app.use(express.bodyParser());
    app.use(app.router);
    app.all("/*", function(req, res, next) {
        res.sendfile("index.html", { root: __dirname + "/../app" });
    });
    app.use(express.errorHandler({
        dumpExceptions: true, 
        showStack: true
    }));
});

但是,这现在将所有请求作为我的index.html文件提供,因此我从requireJS收到以下错误:

Uncaught SyntaxError: Unexpected token < 

我尝试将以下内容添加到我的nodeJS app.js中,以便正确地提供我的资源:

app.use("/js", express.static(__dirname + "/../app/js"));
app.use("/img", express.static(__dirname + "/../app/img"));
app.use("/css", express.static(__dirname + "/../app/css"));
app.use("/partials", express.static(__dirname + "/../app/partials"));

但仍然没有运气。

我还尝试将app.all语句替换为:

app.use(function(req, res) {
  // Use res.sendfile, as it streams instead of reading the file into memory.
  res.sendfile(__dirname + '/../app/index.html');
});

但这也不起作用。我怎么做才能让angularJS html5mode与nodeJS和Express一起工作?感谢。

您的初始修复(声明特定前缀的静态中间件处理程序)应该可以正常工作,但您需要确保它们在之前任何其他路由(和app.router),尽管您不需要明确使用它):

// these need to go first:
app.use("/js", express.static(__dirname + "/../app/js"));
app.use("/img", express.static(__dirname + "/../app/img"));
app.use("/css", express.static(__dirname + "/../app/css"));
app.use("/partials", express.static(__dirname + "/../app/partials"));

// any other routes:
app.all("/*", ...);

此外,您需要确保实际声明前缀静态处理程序正常(正确路径),否则它们将无法找到任何请求的文件,并且请求将传递到中间件链并最终由catch-all处理程序(应该很容易通过注释掉catch-all处理程序进行测试,看看是否有任何JS / CSS / ...请求正常工作)。

配置express 4服务器,如:

app.use(express.static(__dirname + '/public'));

app.get('/*', function(req, res){
    res.sendFile(__dirname + '/public/index.html');
});

和角度似的:

app.config(function($stateProvider, $urlRouterProvider, $locationProvider){
    $stateProvider
        .state('home', {
            url: '/',
            templateUrl: 'templates/main.html'
        })
        .state('register', {
            url: '/register',
            templateUrl: 'templates/register.html'
        });

    $urlRouterProvider.otherwise("/");
    $locationProvider.html5Mode({
        enabled: true,
        requireBase: false
    });
});

我正在使用客户端上的Angularjs和Requirejs处理Web应用程序,并在服务器上使用Nodejs。

以下是一些示例代码,向您展示我如何设置它。

  

请注意,此示例显示的是哈希网址,但您可以通过修改中间件功能和角度配置轻松更改

中间件功能

isXHR: function (req, res, next) {
    if (req.xhr || req.get("angular-request") === "ajaxRequest") {
        next();
    } else {
        var url = req.url;
        var urls = url.split("/");
        var last = _.last(urls);
        urls = _.without(urls, last);
        url = urls.join("/") + "#/" + last //remove the hash if you want to make it html5mode;

        res.redirect(url);
    }
}

服务器路由配置

//I'm using express-namespace to group my routes
app.namespace("/requirements", function(){
   //Shared local variable used across the application
   var info = {
        app: {
            title: "Requirements",
            module: "app/requirements" // where the angular application stored
        }
    }
    //this is the main url that will user request
    Route.get("/", function (req, res) {
        res.cookie("profileRegisterationSteps", 0);
        res.render("app/requirements/index", info);
    });
   //this is the url angular js will request
    Route.get("type", filters.isXHR, function (req, res) {
        res.render("app/requirements/profile/type", info);
    });
 })

客户端路由配置

require(['App', 'underscore', 'ngAmd'/*angular amd*/, 'autoload'/*No Sense*/, 'appLoader' /*i used to load my scripts file for the route user requested (not all scripts files only who requested) before template laoded*/, 'appRoute'/*this is a list of routes*/], function (app, _, amd, autoload, loader, routes) {

app.config(function ($routeProvider, $locationProvider, $httpProvider) {
    //remove a clearn URL
    $locationProvider.html5Mode(false);

    //ku dar header kan si uu server ka u ogaado Request in yahay Ajax
    $httpProvider.defaults.headers.common['angular-request'] = "ajaxRequest";

    //Route Config
    var Route = $routeProvider;
    //get all routes objects that defined in routes module
    _.each(routes, function (route) {
        // extend the routes module objects and use its properties
        Route.when(route.url, _.extend(route, {
            //call returning function in loader module and write the promise
            resolve: _.extend(loader(route))
        }));
    });
    Route.otherwise({
        redirectTo: "/"
    });

});

  //start the application
  amd.bootstrap(app);
 });

Apploader文件

require.config({
    paths: {
        //pages
       type: "Apps/requirements/pages/type"
   }
});
 define(['App'], function(app) {
    return function (options) {
      return {
        loader: function ($q, $rootScope) {
            var defer = $q.defer();
            var module = options.name// the name of the route (this name corresponds to the requirejs module name above;

            if (!!(module)) {
                if (require.defined(module)) {
                    defer.resolve();
                } else {
                    require([module], function () {
                        $rootScope.safeApply(function () {
                            defer.resolve();
                        })
                    });
                }
            } else {
                defer.resolve();
            }

            return defer.promise;
        }
      }
    }
 });

路由文件

define(function(){
  return {
     {
        name        : "type",
        url         : "/",
        templateUrl : "/requirements/type",
        view        : 'services'
    }

 }
