部署-通过AngularJS CORS检索的数据

Question

我目前正在阅读Adam Freeman的“ Pro
AngularJS”。在阅读这些示例时，他让读者使用Angular（当然）与Deployed服务器资源一起创建了运动商店应用。部署资源已设置为返回要填充到模型中的JSON数据。我正在使用NodeJS运行服务器。当前在端口5000（http://localhost:5000/sportsstore/app.html）上设置。部署的资源正在端口5500（http://localhost:5500/products）上运行。当点击已部署时，响应如下：

[

]

我正在尝试通过使用来检索此数据$http.get：

$http.get("http://localhost:5500/products")
    .success(function (data) { ... })
    .error(function (error) { ... });

但是，这总是返回错误：

XMLHttpRequest cannot load http://localhost:5500/products. No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'http://localhost:5000' is therefore not allowed access.

研究表明，Angular和CORS存在/存在一些问题，并且必须将标头配置为运行跨域请求。结果，我将以下内容添加到我的app.config中：

$http.defaults.useXDomain = true;
delete $http.defaults.headers.common['X-Requested-With']; // this isn't needed anymore, but was put here as a just-in-case

尽管添加了这些设置，但仍然出现错误。部署文档说，它是为CORS（跨域请求）自动配置的，只要请求中不包含无效的自定义标头，它就会发送适当的标头信息。我很确定我的请求中没有无效的自定义标头：

Accept: application/json, text/plain, */*
Cache-Control: max-age=0
Origin: http://localhost:5000
Referer: http://localhost:5000/sportsstore/app.html
User-Agent: Mozilla/5.0 (Windows NT 6.3; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/34.0.1847.131 Safari/537.36

我的问题：为了将Deployed配置为允许CORS请求进行处理，我是否还需要进行其他配置？
该书未指定任何特殊的Angular标头设置或其他任何内容。

Bic，将部署的版本升级到版本0.6.10。这对我有用。现在，我可以处理获取请求。AngularJS代码和Adam Freeman的书似乎都不是错误。

在书中，他确实提到他将已部署的程序包括在http://www.apress.com/9781430264484上的源代码下载中。那是0.6.9版本。我敢肯定它可以正常工作。比起尝试找到0.6.10版本要容易得多。如果要使用该版本，则为：

https://www.versioneye.com/nodejs/deployd/0.6.10

它不是安装程序，因此您必须将其粘贴到已部署的目录中，以替换node_modules。
