grunt connect proxy : proxy created 但我得到一个 404

grunt connect proxy : proxy created but i get a 404

我目前有一个使用 yeoman 配置的简单 angular 应用程序,我正在尝试的唯一自定义是使用 g运行t-connect-proxy。所以我按照说明修改了我的 G运行tfile :

var proxySnippet = require('grunt-connect-proxy/lib/utils').proxyRequest;
module.exports = function (grunt) {
    ...
    grunt.initConfig({
        ...
        connect: {
            ...
            server: {
                proxies: [
                {
                     context: '/api',
                     host: 'somevirtualhost',
                     port: 8080,
                     https: false,
                     changeOrigin: true
                }
                ]
            },
            livereload: {
                options: {
                    open: true,
                    middleware: function (connect) {
                        return [
                            proxySnippet,
                            ...
                        ];
                    }
                }
            },
            ...
        },
    });
    ...
    grunt.registerTask('serve', 'Compile then start a connect web server', function (target) {
        ...
        grunt.task.run([
            ...
            'configureProxies:server',
            ...
        ]);
    });
}

我在控制器中尝试了以下操作:

var Versions = $resource('/api/version/:versId', { versId: '@id' });
var version = Versions.get({ versId: 'Ultra' }, function () {
    console.log('here I am');
});

当我 运行 g运行t 服务时,我可以看到代理已创建:

Running "configureProxies:server" (configureProxies) task
Proxy created for: /api to somevirtualhost:8080

但是在网页的控制台中我得到:

Failed to load resource: the server responded with a status of 404 (Not Found)
http://localhost:9000/api/version/Ultra 

有什么想法吗?

我在这里找到了一些线索:https://github.com/drewzboto/grunt-connect-proxy/issues/69 我什么都不懂,但现在我在我的代理中添加了 headers 选项:

proxies: [
          {
              context: '/api',
              host: 'somevirtualhost',
              port: 8080,
              https: false,
              changeOrigin: true,
              headers: {
                  'host': 'somevirtualhost'
              },
          }
        ]

它似乎有效
