IIS 上的 WCF 服务 - WSDL 为空

Question

我创建了一个 WCF 服务并将其托管在我的 IIS 服务器上。然后，我需要编辑 schemaLocation。我关注了 this post.

当我将“?wsdl”添加到 url 时，我得到一个空白页面。如果我尝试使用来自 SOAPui 的 WSDL 来测试它，我会得到这个“加载错误 [http://xx.xxx.xx.xx:8095/CardServiceLib.CardService.svc/service?wsdl]：org.apache.xmlbeans.XmlException：org.apache.xmlbeans.XmlException：错误：文件意外结束之后nul"

如果我删除 HTTPGetUrl，WSDL 是正确的，但 schemaLocation 不是我想要的。使用链接 post 制作的 mod，schemaLocation 是完美的，但 WSDL 是空的...为什么？

这有效，但不是我想要的（生成 WSDL 但链接错误）：

<serviceMetadata httpGetEnabled="True" httpsGetEnabled="True" />

这不是（不生成 WSDL --> 空白页！！！）：

<serviceMetadata httpGetEnabled="True" httpsGetEnabled="True" httpGetUrl="http://xx.xx.xx.xx.:8095/MyService.svc/endpoint"/>

这是我在 IIS 服务器 7

已解决！！我添加了这个

address="http://192.168.1.2/Demo.Service/MultiEndPointsService.svc/basic"

在我的端点标记中，如 this link 中所写。

我怀疑问题与访问 WSDL 所需的身份验证有关。

当尝试直接访问元数据 URL 时，网站指示如下：
“需要身份验证”
“服务器 http://...:8095 需要用户名和密码。”

您需要提供正确的凭据或放宽对 WSDL 的权限。
