百度下:基本都是这个鸟样子……

connect: {
  options: {
    port: 9000,
    // Change this to '0.0.0.0' to access the server from outside.
    hostname: 'localhost',
    livereload: 35729,

    // remove next from params
    middleware: function(connect, options) {
      return [
        function(req, res, next) {
          res.setHeader('Access-Control-Allow-Origin', '*');
          res.setHeader('Access-Control-Allow-Methods', 'GET,PUT,POST,DELETE');
          res.setHeader('Access-Control-Allow-Headers', 'Content-Type');

          // don't just call next() return it
          return next();
        },

        // add other middlewares here 
        connect.static(require('path').resolve('.'))

      ];
    }
    },
    },

关键是?

这东西有毛用?

然后,你想到,nginx代理转发??但是,你要手工刷新啊??

哥哥!!

不想手工刷新!!!

所以,值好,直接nodejs转发!!

然后,我想写这个文章的时候,自己配置完成后,然后谷歌……

居然,这位,已经写了……

所以,只好拿来主义了!!简略翻译下哈!!

插件地址:https://www.npmjs.com/package/grunt-connect-proxy




I'm working on a webapp using Angular.js with the help of the Yeoman workflow framework. Because the backend service runs on localhost:8080 and my dev server (through Grunt) on localhost:9000, requests result in same-origin policy errors due to the port difference. To get around this during development, we can setup CORS through a proxy on Grunt.

我angularjsjs库搞webapp,采用yeoman管理工作流。服务端在8080端口,而前端grunt 却跑在9000端口,由于浏览器的同源策略,所以会引起跨域问题。为了解决这个问题,我们通过 grunt-connect-proxy转发。



Much of this post is adapted from the grunt-connect-proxy documentation for my project's Yeoman-created Grunt.js.

Tools used: 

  • yo (Yeoman) 1.0.7-pre.2

  • generator-angular 0.7.1

  • grunt-cli v0.1.11

  • grunt v0.4.2

  • grunt-connect-proxy 0.1.7


I started with a working Angular webapp with Yeoman and friends, so check out Yeoman and generator-angular to get up to speed.

  1. Install grunt-connect-proxy in the root of your project folder. The --save-dev parameter tells NPM to add grunt-connect-proxy as a devDependency to your project's package.json.


    1
    npm install grunt-connect-proxy --save-dev

    NOTE: The grunt-connect-proxy documentation states that you can enable it by adding the following line to your Gruntfile.js:


    1
    grunt.loadNpmTasks('grunt-connect-proxy');


    When I added it, Grunt registered the task twice and while this didn't appear to cause any problems, this is the reason that I leave it out of my Gruntfile.js.

    Add a proxies config to your connect config. I added it just before livereload because we'll be modifying that config in the next step.

     proxies: [        {          context: '/api', // 这是你希望出现在grunt serve服务中的路径,比如这里配置的是http://127.0.0.1:9000/api/          host: 'www.ngnice.com', // 这是你希望转发到的远端服务器          port: 80, // 远端服务器端口          changeOrigin: true, // 建议配置为true,这样它转发时就会把host带过去,比如www.ngnice.com,如果远端服务器使用了虚拟主机的方式配置,该选项通常是必须的。          rewrite: {            '^/api/': '/remote_api/'  // 地址映射策略,从context开始算,把前后地址做正则替换,如果远端路径和context相同则不用配置。          }        }      ],

    11.jpg

    This rewrite rule tells the proxy that ever call which starts with user gets redirected to theuser context we defined earlier. It won't work the other way round, since the context has to be defined beforehand, but that shouldn't matter actually. Feel free to include as many proxies and rewrites. Using this structure everything should work fine.

    // The actual grunt server settings
    connect: {
      options: {
        // content removed for brevity
      },
      proxies: [{
        context: '/data-service-path', // the context of the data service
        host: 'localhost', // wherever the data service is running
        port: 8080 // the port that the data service is running on
      }],
      livereload: {
        // content removed for brevity
      },

    Check out the grunt-connect-proxy documentation for details on proxy configuration.


  2. Add the grunt-connect-proxy proxyRequest function to middleware in connect.livereload.options. This causes all requests to the Grunt server for the path of the configured context to be proxied; I'll provide some examples at the end of the post on how URLs are mapped by default. Here's what we end up with:

    // The actual grunt server settings

        // content removed for brevity
      },
      proxies: [{
        context: '/data-service-path', // the context of the data service
        host: 'localhost', // wherever the data service is running
        port: 8080 // the port that the data service is running on
      }],
      livereload: {
        options: {
          open: true,
          base: [
            '.tmp',
            '<%= yeoman.app="">'
          ],
          middleware: function (connect, options) {
            var middlewares = [];
               
            if (!Array.isArray(options.base)) {
              options.base = [options.base];
            }
               
            // Setup the proxy
            middlewares.push(require('grunt-connect-proxy/lib/utils').proxyRequest);
     
            // Serve static files
            options.base.forEach(function(base) {
              middlewares.push(connect.static(base));
            });
     
            return middlewares;
          }
        }
      },

    This is different from the example given in the grunt-connect-proxy documentation in that my version doesn't make anything browseable.

    这是我配置代码:


  3. connect: {
      options: {
        port: 9019,
        // Change this to '0.0.0.0' to access the server from outside.
        //hostname: 'localhost',
        //hostname: '127.0.0.1',
        hostname: '192.168.1.254',
        livereload: 35719
      },
      proxies: [{
        context: '/jsse', // the context of the data service
        host: 'localhost', // wherever the data service is running
        port: 8080 // the port that the data service is running on
      }],
      livereload: {
        options: {
          open: true,
    
          middleware: function (connect) {
            var middlewares= [
              connect.static('.tmp'),
              connect().use(
                '/bower_components',
                connect.static('./bower_components')
              ),
              connect().use(
                '/app/styles',
                connect.static('./app/styles')
              ),
              connect.static(appConfig.app),
              require('grunt-connect-proxy/lib/utils').proxyRequest
            ];
            return middlewares;
          }
        }
      },
  4. Add the configureProxy task to the Grunt serve task. Here's what my serve task ends up as:


    1
    2
    3
    4
    5
    6
    7
    8
    9
    10
    11
    12
    13
    14
    15
    grunt.registerTask('serve', function (target) {
      if (target === 'dist') {
        return grunt.task.run(['build', 'connect:dist:keepalive']);
      }
     
      grunt.task.run([
        'clean:server',
        'bower-install',
        'concurrent:server',
        'autoprefixer',
        'configureProxies:server', // added just before connect
        'connect:livereload',
        'watch'
      ]);
    });

    blob.png

  5. Start up the Grunt server with


    1
    grunt serve

    and you should see


    1
    2
    Running "configureProxies:server" (configureProxies) task
    Proxy created for: /data-service-path to localhost:8080

    in the console.

That's all for installation and configuration.

Here are some example proxied URLs:

Grunt serverBackend server
http://127.0.0.1:9000/data-service-pathhttp://127.0.0.1:8080/data-service-path
http://127.0.0.1:9000/data-service-path/foo/1http://127.0.0.1:8080/data-service-path/foo/1


For an Angular resource whose endpoint is over the proxy then, the proxy context must be used in the resource URL, something like this:

?

1
2
3
4
angular.module('myServices', ['ngResource'])
.factory('Foo', ['$resource', function($resource) {
    return $resource('/data-service-path/foo/:id', {id: '@id'});
}]);

To use a different path on the Grunt and backend servers, use the rewrite config; for example:

?

1
2
3
4
5
6
7
8
9
10
11
12
13

// The actual grunt server settings
connect: {
  options: {
    // content removed for brevity
  },
  proxies: [{
    context: '/api', // the path your application uses
    host: 'localhost', // wherever the data service is running
    port: 8080, // the port that the data service is running on
    rewrite: {
        // the key '^/api' is a regex for the path to be rewritten
        // the value is the context of the data service
        '^/api': '/data-service-path'
    }
  }],
  livereload: {
    // content removed for brevity
  },
  test: {

Example URLs:

Grunt serverBackend server
http://127.0.0.1:9000/apihttp://127.0.0.1:8080/data-service-path
http://127.0.0.1:9000/api/foo/1http://127.0.0.1:8080/data-service-path/foo/1


Then our example resource code becomes:


1
2
3
4
angular.module('myServices', ['ngResource'])
.factory('Foo', ['$resource', function($resource) {
    return $resource('/api/foo/:id', {id: '@id'});
}]);
