如何从angularjs访问couchdb跨域

Question

我已经设置了一个本地环境,我从json文件中加载数据:

var Players = $resource('data/players.json');
var players = Players.query(function(){});

而且效果很好.

现在我想在不同的域(http://playball.iriscouch.com/players)上访问CouchDB,并基于google buzz示例我尝试了以下内容,但我无法使其工作:

var Players = $resource('http://playball.iriscouch.com/players',  
  {alt: 'json', callback: 'JSON_CALLBACK'},
  {get:     {method: 'JSON'}
});

var players = Players.query(function(){});

我只是收到一个空数组...任何想法？

谢谢你!

如果您可以控制服务器,请使用 CORS.

要更正您的示例:

var Players = $resource('http://playball.iriscouch.com/players',

  // These params will be set to each request (?alt=json&callback=JSON_CALLBACK),
  // where JSON_CALLBACK placeholder will be replaced with correct callback fn,
  // generated by Angular.
  {alt: 'json', callback: 'JSON_CALLBACK'},

  // You need to configure query method to use JSONP
  {query:     {method: 'JSONP'}
});

var players = Players.query(function(){});

务必检查服务器是否响应正确的数据(开发工具栏 - 网络面板).
