Scala Steam-OpenId和Play框架

我在使用Steam作为OpenId提供程序时遇到问题。在对我的站点进行回调之前，一切都正常，我看到了steam登录网页，我可以使用我的用户登录，但是当执行calback时，我得到了一个异常。 我使用Play2.2和Scala。该代码与上的代码非常相似

堆栈跟踪：

我在返回的URL中看到此错误消息

openid.error=Invalid+claid\u id+或+identity

，但找不到任何相关信息

我错过了什么？谢谢。

这是因为Play Framework OpenID类没有正确生成重定向URL。从代码中的此行打印出

url

变量的值：

.map(url => Redirect(url))

很可能是这样的：

https://steamcommunity.com/openid/login?openid.ns=http%3A%2F%2Fspecs.openid.net%2Fauth%2F2.0
 &openid.mode=checkid_setup
 &openid.claimed_id=http%3A%2F%2Fsteamcommunity.com%2Fopenid
 &openid.identity=http%3A%2F%2Fsteamcommunity.com%2Fopenid
 &openid.return_to=http%3A%2F%2Fwww.mydomain.com%2Fsteam%2Flogin
 &openid.realm=http%3A%2F%2Fwww.mydomain.com

根据OpenID 2.0规范，这是不正确的，特别是在：

如果最终用户输入了OpenID提供程序（OP）标识符，则没有声明的标识符。为了发出OpenID身份验证请求，输入OP标识符时，必须将值“”用作声明的标识符和OP本地标识符

基于此，生成的重定向

url

变量应该是：

https://steamcommunity.com/openid/login?openid.ns=http%3A%2F%2Fspecs.openid.net%2Fauth%2F2.0
 &openid.mode=checkid_setup
 &openid.claimed_id=http%3A%2F%2Fspecs.openid.net%2Fauth%2F2.0%2Fidentifier_select
 &openid.identity=http%3A%2F%2Fspecs.openid.net%2Fauth%2F2.0%2Fidentifier_select
 &openid.return_to=http%3A%2F%2Fwww.mydomain.com%2Fsteam%2Flogin
 &openid.realm=http%3A%2F%2Fwww.mydomain.com

我已经在Play Framework问题跟踪器上为此编写了一个问题：

同时，作为临时破解/修复，您可以在

url

变量上使用任意数量的字符串替换技术，将

openid.claid\u id

和

openid.identity

参数设置为正确的

http://specs.openid.net/auth/2.0/identifier_select

value

https://steamcommunity.com/openid/login?openid.ns=http%3A%2F%2Fspecs.openid.net%2Fauth%2F2.0
 &openid.mode=checkid_setup
 &openid.claimed_id=http%3A%2F%2Fspecs.openid.net%2Fauth%2F2.0%2Fidentifier_select
 &openid.identity=http%3A%2F%2Fspecs.openid.net%2Fauth%2F2.0%2Fidentifier_select
 &openid.return_to=http%3A%2F%2Fwww.mydomain.com%2Fsteam%2Flogin
 &openid.realm=http%3A%2F%2Fwww.mydomain.com
