c# - 为什么我会收到一个错误，即 XML 文档中存在错误？

问题描述

我有一个托管在本地主机上的肥皂网络服务，即使用 Visual Studio 的 iis express。我使用 SOAPUI 发送它的值。如果我传递了正确的值，它可以工作并调试。

但是，如果我传递一个空标签或值，即如果期望一个日期时间并且我传递空标签，那么它甚至在点击 webservices 方法之前就会抛出错误。

那么它是网络服务错误还是soapui错误？

解决方案

我不会将其称为 webservice 或 soapUI 错误：该服务按预期工作并拒绝无效内容。

在定义您的 Web 服务的 WSDL 中将是一个 XML 模式，Web 服务运行时环境可以根据该模式验证传入的请求。如果请求未能通过第一道防线，则调用您的服务毫无意义。
