使用Azure IoT集线器设备设置服务(DPS)时出现未经授权的异常

我正在尝试使用Azure IoT Hub迁移现有解决方案，以使用Azure IoT Hub设备配置服务(DPS(。

设备使用X.509自签名证书进行自我身份验证。

出于测试目的，我可以使用生成证书

openssl req -newkey rsa:2048 -nodes -keyout key.pem -x509 -days 365 -out certificate.pem

公用名设置为mything1
所有其他字段为空

然后我可以使用将这些文件合并为一个文件

openssl pkcs12 -inkey key.pem -in certificate.pem -export -out certificate.p12

选择password作为密码。

然后我有3个文件。

certificate.p12同时包含证书和私钥
包含证书的certificate.pem
包含私钥的key.pem

然后我可以使用直接在物联网集线器中注册此设备

string ThingId = "mything1";
// Register device directly in IoT hub.
{
var certificate = new X509Certificate2(File.ReadAllBytes("certificate.pem"));
string thumb1 = certificate.Thumbprint;
using (var hasher = SHA256.Create())
{
using (var registryManager = RegistryManager.CreateFromConnectionString(iotHubConnectionString))
{
await registryManager.AddDeviceAsync(new Device(ThingId)
{
Authentication = new AuthenticationMechanism()
{
X509Thumbprint = new X509Thumbprint()
{
PrimaryThumbprint = thumb1,
SecondaryThumbprint = thumb1,
}
},
});
}
}
}

然后，在设备注册后，我可以使用证书作为设备身份验证，作为设备连接到IoT集线器。

// Vertifying that certificate is ok etc
// by connecting to an IoT Hub
{
var auth = new DeviceAuthenticationWithX509Certificate(ThingId, new X509Certificate2(File.ReadAllBytes("certificate.p12"), "password"));
var client = DeviceClient.Create(iotHubHostname, auth,
new ITransportSettings[] { new AmqpTransportSettings(Microsoft.Azure.Devices.Client.TransportType.Amqp_WebSocket_Only) });
// Report a value just to make sure it works.
TwinCollection props = new TwinCollection();
props["Hello"] = "World";
await client.UpdateReportedPropertiesAsync(props, new CancellationTokenSource(1000 * 30).Token);
}

这是有效的，也是我今天的解决方案。现在尝试做同样的事情，但使用DPS。

首先为设备创建一个单独的注册：

// Create an individual enrollment for device
using (var provisioningServiceClient = 
ProvisioningServiceClient.CreateFromConnectionString(provisioningServiceConnectionString))
{
var attestation = X509Attestation.CreateFromClientCertificates(new X509Certificate2(File.ReadAllBytes("certificate.pem")));
IndividualEnrollment individualEnrollment =
new IndividualEnrollment(
ThingId,
attestation);
IndividualEnrollment individualEnrollmentResult =
await provisioningServiceClient.CreateOrUpdateIndividualEnrollmentAsync(individualEnrollment);
}

然后在创建注册后，我应该能够将自己作为一个设备。

string globalDeviceEndpoint = "global.azure-devices-provisioning.net";

using (var security = new SecurityProviderX509Certificate(new X509Certificate2(File.ReadAllBytes("certificate.p12"), "password")))
{
ProvisioningDeviceClient provClient = ProvisioningDeviceClient.Create(globalDeviceEndpoint, 
s_idScope, 
security, 
new ProvisioningTransportHandlerHttp());

DeviceRegistrationResult result = await provClient.RegisterAsync(); // Throws exception
Console.WriteLine($"ProvisioningClient AssignedHub: {result.AssignedHub}; DeviceId: {result.DeviceId}");
}

但这引发了一个未经授权的异常：

Unhandled exception. Microsoft.Azure.Devices.Provisioning.Client.ProvisioningTransportException: {"errorCode":401002,"trackingId":"f7ec27c8-dbad-4600-8b47-f46aaa0160de","message":"Unauthorized","timestampUtc":"2021-05-20T14:09:00.8491407Z"}

我在这里做错了什么？

编辑：正如Rajeev在这里回答的那样：https://stackoverflow.com/a/67641996/6877590问题是基本的约束条件：CA:true。

为了解决这个问题(用于测试(

编辑文件/usr/lib/ssl/openssl.cnf
查找[ v3_ca ]
将CA:true更改为CA:false
