我现在使用ng-token-auth
和rails'devise-token-auth
提供了一个非常简单的应用程序。它运行正常,$ auth方法运行良好(例如,登录)。但是,在页面刷新时,access-token
不会保留,也不会使用ipCookie写入cookie。
我的rails应用正在转发正确的标题,如下所示:
Access-Control-Allow-Credentials:true
Access-Control-Allow-Methods:GET, POST, DELETE, PUT, OPTIONS, HEAD
Access-Control-Allow-Origin:http://localhost
Access-Control-Expose-Headers:
Access-Control-Max-Age:0
access-token:XXXXXXXXXXXXXX
Cache-Control:max-age=0, private, must-revalidate

X-Runtime:0.230242
X-XSS-Protection:1; mode=block
但当它通过updateHeadersFromResponse
ng-token-auth
方法运行时,标题返回null - 特别是在ng-token-auth.js的第588行
updateHeadersFromResponse = function($auth, resp) {
var key, newHeaders, val, _ref;
newHeaders = {};
_ref = $auth.getConfig().tokenFormat;
for (key in _ref) {
val = _ref[key];
if (resp.headers(key)) {
newHeaders[key] = resp.headers(key);
}
}
if (tokenIsCurrent($auth, newHeaders)) {
return $auth.setAuthHeaders(newHeaders);
}
};
有没有人遇到过这个?为什么不将标头传递给此$httpProvider
方法?
答案 0 :(得分:13)
我在这篇文章Angular.js saying custom HTTP response header is null
中找到了答案我使用的是多域设置,因此API域需要在CORS配置中有一些额外的公开标头。所以在rails-cors gem中我为access-token添加了一个额外的公开值:
config.middleware.insert_before 0, "Rack::Cors" do
allow do
origins 'api.com'
resource '*',
:headers => :any,
:methods => [:get, :post, :delete, :put, :options, :head],
:expose => ['access-token', 'expiry', 'token-type', 'uid', 'client'],
:max_age => 0
end
end
更新:公开角度所需的所有字段,而不只是一个使其起作用的字段。
