证明可验证凭据类型在c#中可用的回购演示?

Question

我已经成功地测试了idtokenint演示，我正在尝试不成功的认证可验证凭证类型，类似于Woodgrave员工入职演示，这个代码在c#中可用吗?

在我的情况下，我需要Authenticator首先请求VerifiedCredentialExpert VC，但我不知道如何在Authenticator上触发这个，我在issuance_request_config上尝试了这个。我还尝试将requestdcredentials添加到类型VerifiedCredentialExpert中，如下所示，以建议Authenticator首先获得此信息，但没有改变错误行为:

"includeQRCode": false,
"callback": {
//In this sample code we will overwrite the callback and use the HOSTNAME dynamicall
//make sure you use ngrok or something like that when running on a local devbox. 
//The MS AAD VC Request service needs to be able to reach the callback URI
"url": "https://YOURPUBLICREACHABLEHOSTNAME/api/issuer/issuanceCallback",
"state": "STATEWILLBESETINCODE",
"headers": {
"api-key": "OPTIONAL API-KEY for ISSUANCE CALLBACK API"
}
},
//The Authority is the DID from your MS AAD Verifiable Credential service, you can copy this from the VC page in azure portal
"authority": "did:ion: THIS IS YOUR DID FROM THE VC PAGE IN AZURE PORTAL WHICH IS SET IN THE SAMPLE BY COPYING THE VALUE FROM APPSETTINGS.JSON   ",
"registration": {
"clientName": "Verifiable Test Register Verifiable Credential"
},
//The type needs to be the same as defined in the rules json definitione. The manifest can be copied after the credential has been
//created in the azure portal
"type": "VerifiedTestRegistration",
"manifest": "CREDENTIAL URL IN THIS SAMPLE WILL BE COPIED FROM APPSETTINGS.JSON",
//Recommendation is to protect issuance payload with a PIN code. 
//The pincode is set to a random value in code and will be displayed in the UI to the user
"pin": {
"value": "123456",
"length": 4
},
//This is an example payload which will be used in the rules file of the credential.
//The rules files maps information from the ID Token (hint) to the VC
"claims": {
"country_of_registry": "",
"registration_number": "",
},
//You can request multiple verifiable credentials at once that's whty the requestCredentials is an array
"requestedCredentials": [
{
"type": "VerifiedCredentialExpert",
"purpose": "Required presentation of verifiable credentials expert to get Test Registration card.",
//You can trust multiple issuers who might be issuing the same credential type (for example certifications or diplomas)
//You need to specify at least 1 trusted issuer DID, for this sample code we copy the IssuerAuthority from appsettings to the request
//"acceptedIssuers": [ "did:ion: copied from your VC portal in this sample the code copies it from APPSETTINGS.JSON" ]
"acceptedIssuers": [ "theaccepetedidissuer" ]
}
]

}

这些是显示和规则:

我正在测试iphone12 pro最新的iOS版本。

问题张贴在这个git项目，但不幸的是没有得到帮助。

谢谢你的帮助，Sergio

Sergio，

有几件事你应该回顾一下样本:关于规则文件:

1. 对于VC，您可以删除合同，但保留VCType

显示文件:2. 我还在您的案例中添加了从VC获得的索赔first_name和last_name。

在这样做之后，我的示例通过Postman直接与请求API一起工作，尝试先让它工作，然后使其在c# 中工作。我还在调查的一件事是，我没有注意到正在录制的关于所请求的VC类型的演示。我相信它应该有一个，但我仍在跟进团队。试一下，让我们知道它是否有效
