AngularJS和Apiary.IO - 无法读取任何响应头？ [英] AngularJS and Apiary.IO - can't read any response headers?

问题描述

我使用Apiary.io嘲笑我的API。但不知何故，我无法从响应对象使用angularJS读取任何头。而且我相信我至少有内容类型：应用程序/ JSON正确建立在萤火检查。在角code应该正确读取头太大，我可以发送请求到别的地方比apiary.io ...

I mocking my API using Apiary.io. But somehow I cannot read any headers from response object using angularJS. And I am sure i have at least Content-Type: application/json correctly set-up by checking in firebug. Code in Angular should read headers correctly too as i can print them when sending request to somewhere else than apiary.io...

  $http.get('http://ies.apiary.io/some').then(function(response) {  
    console.log("ok",response.headers('Content-Type'));
    },function(response){console.log("err",response);});

推荐答案

这一切都归结为在Firefox中的错误：的 https://bugzilla.mozilla.org/show_bug.cgi?id=608735

It all boils down to a bug in firefox: https://bugzilla.mozilla.org/show_bug.cgi?id=608735

有关要求CORS，Firefox是不会回来了req.getAllRequestHeaders（）什么，虽然req.getRequestHeader（Content-Type的'）返回正常。

For CORS request, firefox is not returning anything for req.getAllRequestHeaders(), although req.getRequestHeader('Content-Type') returns properly.

无论是FF的bug已被固定或角必须解决它（如jQuery不会），或者你必须去更深入和直接使用XmlHtt prequest实例。

Either FF bug has to be fixed or Angular must work around it (as jQuery does) or you must go deeper and use XmlHttpRequest instance directly.

这是也许也有关，但可能不是核心问题：

This was maybe also related, but probably not the core issue:

不过，前几天，Apiary.io没有设置最大年龄在 CORS 头。因此，如果你有一个最小的蓝图，你可能有 CORS pre-飞行响应缓存，即使你添加更多的资源，你的蓝图，因此后续的请求可能被禁止

However, few days ago, Apiary.io was not setting Max-Age in CORS headers. Thus, if you had a minimal blueprint, you might have CORS pre-flight response cached and thus subsequent requests may be disallowed even if you added additional resources to your blueprint.

最大年龄现在设置为10秒，所以它应该正常工作。但是，根据您的浏览器，pre-飞行缓存仍可能影响到你。尝试清除它，或者在其他浏览器中测试这个程序。

Max-Age is now set to 10 seconds, so it should work properly. However, depending on your browser, pre-flight cache might still affect you. Try purging it or test this app in another browser.
