OData 客户端在版本 8.x 中过时的凭据属性

Question

我阅读了 Microsoft.OData.Client 8.x 的更改日志。有一个声明“从 DataServiceContext 类中删除了过时的凭据属性。配置凭据的推荐方法是通过可以使用 IHttpClientFactory 提供的 HttpClientHandler”。 https://learn.microsoft.com/en-us/odata/changelog/odatalib-8x

我曾经这样初始化 Microsoft.OData.Client.DataServiceContext 容器：

Container _dataContext = new Container(new Uri(url))
{
    Credentials = CredentialCache.DefaultNetworkCredentials
};

我使用 Unchase Connected Service 来消费 OData。不再支持使用凭据进行初始化。您有以新的推荐方式设置凭据的经验吗？

经过我们团队的讨论，我们通过实现自定义 HTTP 客户端工厂找到了解决方案。

HttpClientHandler

允许您设置

Credentials

。

public class DataContextFactory
{
    public static Container CreateContainer(string uri)
    {
        var container = new Container(new Uri(uri))
        {
            HttpClientFactory = new CustomHttpClientFactory()
        };
        return container;
    }
}

定制工厂的代码如下...

public class CustomHttpClientFactory : IHttpClientFactory
{
    public HttpClient CreateClient(string name)
    {
        return CreateHttpClient();
    }
    
    public static HttpClient CreateHttpClient()
    {
        var handler = new HttpClientHandler
        {
            Credentials = CredentialCache.DefaultNetworkCredentials
        };
        return new HttpClient(handler);
    }
}

最后，用法...

public class ODataProvider
{
    private static readonly string uri = "http://...../odata";
    private static readonly Container _container = DataContextFactory.CreateContainer(uri);
    
    public static List<Gen01Record> GetSifRecords(string runNumber)
    {
        if (!runNumber.IsNumeric()) return [];
    
        var run = int.Parse(runNumber);
        var records = _container.Communicator.GetSifInformationByRunNumber(run).GetAllPages().Select(x => x.Records).Single().ToList();
        return records;
    }
}
