Java 如何根据特定路径更改gulp端口

我是gulp的新手我在应用程序中使用gelp服务器，我在端口8080上安装了一个java服务器我想在另一个项目中使用oAuth2进行身份验证我使用grunt，这是我如何将用户重定向到oAuth2的

这是我的Grunfile代码

connect: {
  options: {
    port: 9000,
    // Change this to '0.0.0.0' to access the server from outside.
    hostname: 'localhost',
    livereload: 35729
  }, proxies: [
    {
      context: [
        '/_ah',
        '/secured',
        '/oauth2login',
        '/oauth2callback'
      ],
      host: 'localhost',
      port: 8080,
      https: false,
      changeOrigin: false,
      xforward: false
    }
  ]
}

现在我想在gulp上做同样的事情，这里是我的gulpfile.js代码

var options = {
    port: 3000,
    ghostMode: {
        clicks: false,
        location: false,
        forms: false,
        scroll: true
    },
    injectChanges: true,
    logFileChanges: true,
    logLevel: 'debug',
    logPrefix: 'gulp-patterns',
    notify: true,
    reloadDelay: 0, //1000,
    online: false,
    proxies: [
    {
      context: [
        '/_ah',
        '/secured',
        '/oauth2login',
        '/oauth2callback'
      ],
      host: 'localhost',
      port: 8080,
      https: false,
      changeOrigin: false,
      xforward: false
    }
  ]
};

我添加了代理，但没有工作。我想这样做，因为在我的app.run中，我想使用oAuth2对用户进行身份验证

这是我的应用程序

app.run(function($rootScope, datastoreUser){

  datastoreUser.LoginUser("me").then(function(result){

    console.log("User is authenticated");
    console.log(result);

  },function(error){
    console.log("An error occured user is not authenticated");
    console.log(error);
    window.location.href = '/oauth2login';
  })
})

如果有人需要我的问题，我找到了解决办法

我在这里添加了http代理中间件模块代码

var proxyMiddleware = require('http-proxy-middleware');
var options = {
    port: 3000,
    ghostMode: {
        clicks: false,
        location: false,
        forms: false,
        scroll: true
    },
    injectChanges: true,
    logFileChanges: true,
    logLevel: 'debug',
    logPrefix: 'gulp-patterns',
    notify: true,
    reloadDelay: 0, //1000,
    online: false
};
function serveApp() {
    gulp.watch([config.sass], ['sass']);

    options.server = {
        baseDir: [
            config.client,
            config.tmp
        ]
    };
    options.files = [
        config.client + '/**/*.*',
        '!' + config.sass,
        config.tmp + '/**/*.css'
    ];

    options.middleware = proxyMiddleware([
        '/_ah',
        '/secured',
        '/oauth2login',
        '/oauth2callback'
      ],
    {
      target: 'http://localhost:8080'
    });

    browserSync(options);
}
