Question

我已经通过“添加服务参考”（简化的WSDL，包括在下面）从WSDL在Visual Studio中生成了一个c＃客户端。当我使用此客户端生成对服务的请求时，它将创建具有空xmlns属性的子元素。这是一个示例请求：

<?xml version="1.0" encoding="utf-8"?>
<s:Envelope xmlns:s="http://schemas.xmlsoap.org/soap/envelope/">
    <s:Header>
        <Action s:mustUnderstand="1" 
            xmlns="http://schemas.microsoft.com/ws/2005/05/addressing/none">http://sap.com/xi/WebService/soap1.1</Action>
    </s:Header>
    <s:Body xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
        xmlns:xsd="http://www.w3.org/2001/XMLSchema">
        <MySearchInput xmlns="http://www.example.com/mySearch">

            <SearchDetails xmlns="">

                <CompanyName>asda</CompanyName>
            </SearchDetails>
        </MySearchInput>
    </s:Body>
</s:Envelope>

要使其成为对服务的有效请求，SearchDetails元素不应具有此空的xmls属性，它应继承其父级MySearchInput上定义的默认名称空间元件。

我可以对wsdl进行更改，以便客户端生成所需的请求XML吗？

我有一个解决方法，涉及更改Visual Studio创建的代码生成文件，但是我怀疑应该有一个更优雅的解决方案，包括更改wsdl本身？

Answer 1

我在另一个StackOverflow问题中找到了答案。我认为，尽管具有相同的解决方案，但该问题的具体内容可能足以确保它是一个不同的问题。

Why is Oxygen generating child elements with empty xmlns attributes?

解决方案是将elementFormDefault="qualified"添加到WSDL中的schema元素。

<xsd:schema targetNamespace="http://www.example.com/mySearch" 
            xmlns="http://www.example.com/mySearch" 
            xmlns:xsd="http://www.w3.org/2001/XMLSchema"
            elementFormDefault="qualified">

为什么我的SOAP请求不正确地为子元素包含一个空的xmlns属性？
