Question

我正在尝试使用Visual Studio为OData v4服务生成客户端代码。我的服务在没有DNS名称的服务器上运行，并且正在使用HTTPS的自签名证书。我的服务不适用于HTTP。

当我运行OData客户端代码生成器T4模板时，我在本文的底部得到了SSL错误。当我尝试通过“添加连接服务”添加服务时上下文菜单，我收到一条错误消息，说它无法连接。

我认为VS没有连接到我的服务，因为SSL证书与URL的域名不匹配，因为服务器是通过IP地址而不是域名访问的。如果这是一个客户端程序，我可以编写自己的证书验证例程，覆盖现有的策略。但是，由于此代码在Visual Studio中运行，因此我无法访问运行时（我认为）。

当然，我不是第一个反对这一点的人。当您的服务仅通过IP地址提供时，如何生成OData客户端？

我的OData服务URI（来自T4模板）：

public const string MetadataDocumentUri = "https://10.144.128.44/mgmt/odata/$metadata";

Answer 1

您可以检查证书中的dns名称，将此名称加上IP地址放在主机文件中，然后根据dns名称进行连接。

生成OData客户端时忽略SSL错误
