使用DotNetOpenId使ClaimsResponse工作的秘诀是什么？
例如，在这段代码中（来自Scott Hanselman's blog），ClaimsResponse对象应该有很多很好的小东西，比如'nickname'和'email address'，但ClaimsResponse对象本身就是'null'：< / p>
OpenIdRelyingParty openid = new OpenIdRelyingParty();
if (openid.Response != null)
{
// Stage 3: OpenID Provider sending assertion response
switch (openid.Response.Status)
{
case AuthenticationStatus.Authenticated:
ClaimsResponse fetch = openid.Response.GetExtension(typeof(ClaimsResponse)) as ClaimsResponse;
string nick = fetch.Nickname;
string homepage = openid.Response.ClaimedIdentifier;
string email = fetch.Email;
string comment = Session["pendingComment"] as string;
string entryId = Session["pendingEntryId"] as string;
if (String.IsNullOrEmpty(comment) == false && String.IsNullOrEmpty(entryId) == false)
{
AddNewComment(nick, email, homepage, comment, entryId, true);
}
break;
}
}
起初，我认为这是因为我没有使用'ClaimsRequest'重定向到提供程序...但是使用此代码重定向到OpenId提供程序仍然没有帮助：
OpenIdRelyingParty openid = new OpenIdRelyingParty();
IAuthenticationRequest req = openid.CreateRequest(openid_identifier.Text);
ClaimsRequest fetch = new ClaimsRequest();
fetch.Email = DemandLevel.Require;
fetch.Nickname = DemandLevel.Require;
req.AddExtension(fetch);
req.RedirectToProvider();
我做错了什么？或者让其他开发者经历同样的痛苦？

我不知道你是否已经解决了这个问题，但经过数小时的努力，我找到了解决方案。实际上，您需要更改web.config文件以声明电子邮件和全名 这是web.config对我有用。我从nerddinner项目下载了它。实际上我复制了除web.config以外的所有内容，但我没有收到电子邮件字段。所以后来我发现别的东西是错的。我从nerddinner项目复制了web.config，一切正常。
这里是文件，如果你不想去nerddinner项目。

您的代码看起来很好。但请注意，所有OP都不支持您正在使用的sreg扩展。如果您正在进行身份验证的OP不支持它，那么响应扩展名将为null，如您所见。所以空检查总是一个好主意。
myopenid.com支持sreg，如果你正在寻找一个可以测试的OP。

使用最新版本的DotNet OpenId，这段代码似乎对我很好：
var request = openid.CreateRequest(openid_identifier);
var fields = new ClaimsRequest();
fields.Email = DemandLevel.Require;
fields.Nickname = DemandLevel.Require;
request.AddExtension(fields);
request.RedirectToProvider();
从提供者返回时：
var claimResponse = openid.Response.GetExtension<ClaimsResponse>();
PS：我使用的是MVC，而不是WebForms。
答案 3 :(得分：2)
我用过
/* worked */var fetch = new FetchRequest();
fetch.Attributes.AddRequired(WellKnownAttributes.Contact.Email);
request.AddExtension(fetch);
而不是
/* didnt work*/
var fields = new ClaimsRequest();
fields.Email = DemandLevel.Require;
fields.FullName = DemandLevel.Require;
request.AddExtension(fields);
在回复中尝试
this.Request.Params["openid.ext1.value.alias1"];
只是简单地而不是访问索赔。这在谷歌的ASP.Net中与我合作。
ASP.Net中的问题是，使用ClaimsRequest时请求未完成发送，如果您使用了Fiddler，则可以看到。并且无法正确检索响应，您需要从Request.params中访问直接参数。他们都在那里。

以上都不适用于我（使用PayPal Access作为标识符）在C＃
中以下对我有用：
OpenIdRelyingParty openid = new OpenIdRelyingParty();
protected void Page_Load(object sender, EventArgs e)
{
var response = openid.GetResponse();
if (response != null)
{
switch (response.Status)
{
case AuthenticationStatus.Authenticated:
if (this.Request.Params["openid.ext1.value.alias1"] != null)
{
Response.Write(this.Request.Params["openid.ext1.value.alias1"]);
Response.Write(this.Request.Params["openid.ext1.value.alias2"]);
}
else {
Response.Write("Alias wrong");
}
break;
}
}
}
protected void loginButton_Click(object sender, EventArgs e)
{
var openidRequest = openid.CreateRequest(openIdBox.Text);
var fetch = new FetchRequest();
fetch.Attributes.AddRequired(WellKnownAttributes.Contact.Email);
fetch.Attributes.AddRequired(WellKnownAttributes.Name.FullName);
openidRequest.AddExtension(fetch);
openidRequest.RedirectToProvider();
}

在我从示例中复制的web.config中进行了以下更新之后，我可以正确地接收参数。
<section name="dotNetOpenAuth"
type="DotNetOpenAuth.Configuration.DotNetOpenAuthSection"
requirePermission="false"
allowLocation="true"/>
并单独添加
<configsections>
