我将 WCF WS 作为控制台应用程序运行，并且在使用 Web 浏览器获取 wsdl 时缺少操作信息 http://localhost:7903/MyService/?wsdl
这是为什么？下面提取的 wsdl 有用吗？
<wsdl:definitions xmlns:wsdl="http://schemas.xmlsoap.org/wsdl/" xmlns:xsd="http://www.w3.org/2001/XMLSchema"xmlns:soapenc="http://schemas.xmlsoap.org/soap/encoding/" xmlns:wsu="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-utility-1.0.xsd" xmlns:soap="http://schemas.xmlsoap.org/wsdl/soap/"xmlns:soap12="http://schemas.xmlsoap.org/wsdl/soap12/" xmlns:tns="http://tempuri.org/"xmlns:wsa="http://schemas.xmlsoap.org/ws/2004/08/addressing" xmlns:wsx="http://schemas.xmlsoap.org/ws/2004/09/mex"xmlns:wsap="http://schemas.xmlsoap.org/ws/2004/08/addressing/policy" xmlns:wsaw="http://www.w3.org/2006/05/addressing/wsdl"xmlns:msc="http://schemas.microsoft.com/ws/2005/12/wsdl/contract" xmlns:i0="http://www.mycompany.com/nis/MyService/wsdl/v1.0"xmlns:wsp="http://schemas.xmlsoap.org/ws/2004/09/policy" xmlns:wsa10="http://www.w3.org/2005/08/addressing"xmlns:wsam="http://www.w3.org/2007/05/addressing/metadata" name="ptMyService" targetNamespace="http://tempuri.org/">
<wsdl:import namespace="http://www.mycompany.com/nis/MyService/wsdl/v1.0" location="http://0.0.0.0:7903/MyService/?wsdl=wsdl0"/>
<wsdl:types/>
<wsdl:binding name="BasicHttpBinding_IptMyService" type="i0:IptMyService">

</wsdl:binding>
<wsdl:service name="ptMyService">

<soap:address location="http://0.0.0.0:7903/MyService/"/>
</wsdl:port>
</wsdl:service>
</wsdl:definitions>
实际的 WSDL 如下所示:

最佳答案
确保您的操作方法没有ReplyAction设置为“*”，因为生成 WSDL 元数据的 WsdlExporter 会忽略此类方法。
[OperationContract(ReplyAction="*")]
string SampleMethod(string msg);
根据 MSDN :
Specifying an asterisk in the service instructs WCF not to add a reply action to the message, which is useful if you are programming against messages directly.
关于web-services - 为什么使用 ?wsdl 后缀获取 URL 会产生没有操作信息的 wsdl？，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/35630511/
