Visual Studio: 如何将 wsdl 集成到 Web 服务中？
Visual Studio: How do I integrate a wsdl into a web service?
我需要创建一个包含 Web 界面的 .exe（独立且没有 IIS）。
现有 WSDL 已转换为 VB.NET 代码。我现在已经插入了 vb.net-文件，但没有 .config 文件。
错误的是，即使引用了界面也没有显示。如果我调用“http://localhost/?WSDL”，将显示以下内容：
<?xml version="1.0" encoding="UTF-8"?>
<wsdl:definitions xmlns:wsam="http://www.w3.org/2007/05/addressing/metadata" xmlns:wsa10="http://www.w3.org/2005/08/addressing" xmlns:wsp="http://schemas.xmlsoap.org/ws/2004/09/policy" xmlns:i0="http://FOO.bar.example.net" xmlns:msc="http://schemas.microsoft.com/ws/2005/12/wsdl/contract" xmlns:wsaw="http://www.w3.org/2006/05/addressing/wsdl" xmlns:wsap="http://schemas.xmlsoap.org/ws/2004/08/addressing/policy" xmlns:wsx="http://schemas.xmlsoap.org/ws/2004/09/mex" xmlns:wsa="http://schemas.xmlsoap.org/ws/2004/08/addressing" xmlns:tns="http://tempuri.org/" xmlns:soap12="http://schemas.xmlsoap.org/wsdl/soap12/" xmlns:soap="http://schemas.xmlsoap.org/wsdl/soap/" xmlns:wsu="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-utility-1.0.xsd" xmlns:soapenc="http://schemas.xmlsoap.org/soap/encoding/" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:wsdl="http://schemas.xmlsoap.org/wsdl/" targetNamespace="http://tempuri.org/" name="FOO_impl">
<wsdl:import location="http://localhost:8000/?wsdl=wsdl0" namespace="http://FOO.bar.example.net"/>
<wsdl:types/>
<wsdl:service name="FOO_impl"/>
</wsdl:definitions>
原始 WSDL 文件具有此处缺少的调用选项。我忘记引用什么了吗？我应该如何整合它？

没有配置文件的原因是你使用了restapi wcf服务，支持http请求调用服务，不适合通过生成代理的方式调用服务类。您可以将绑定修改为 basichttpbinding 或使用 httpclient 调用 webhttpbinding 服务。这是参考：HttpClient Class
