- c - 在位数组中找到第一个零
- linux - Unix 显示有关匹配两种模式之一的文件的信息
- 正则表达式替换多个文件
- linux - 隐藏来自 xtrace 的命令
我向我无法控制的供应商基于 Java 的 Web 服务添加了“服务引用”。
我有这个简单的客户端代码:
Client myClient = new Client();
CapabilitiesType response = client.GetCapabilities(new GetCapabilitiesType1());
myClient.Close();
litCapabilities.Text = response.version;
生成以下 SOAP 信封:
<s:Envelope xmlns:s="http://schemas.xmlsoap.org/soap/envelope/">
<s:Header></s:Header>
<s:Body xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
<GetCapabilities xmlns="http://www.opengis.net/cat/csw/2.0.2"></GetCapabilities>
</s:Body>
</s:Envelope>
到目前为止一切顺利,以上是我从 Trace Viewer 获得的。同时使用 SoapUI 和 Trace Viewer,我可以验证我得到的响应是否正确:

但不知何故,这些数据并没有返回到我的客户端代码。响应对象中的大多数属性都是 NULL。
根据 SOAP 响应,响应对象的一个非 NULL 属性是错误的 (response.version) 它应该是“2.0.2”而不是“1.0.0”
有人知道我遗漏了什么,或者这里可能出了什么问题吗?
或者什么可以帮助我解决这个问题?
最佳答案
我能够弄清楚我的问题: namespace 不匹配。
我请求的 SOAP 信封正文包含:
<csw:GetCapabilities
xmlns:csw="http://www.opengis.net/cat/csw/2.0.2"
xmlns:dc="http://purl.org/dc/elements/1.1/"
xmlns:dct="http://purl.org/dc/terms/"
xmlns:sch="http://www.ascc.net/xml/schematron"
xmlns:gml="http://www.opengis.net/gml"
xmlns:ogc="http://www.opengis.net/ogc"
xmlns:ows="http://www.opengis.net/ows"
xmlns:xlink="http://www.w3.org/1999/xlink" />
在我得到的响应中(仅最相关的字符):
<wrs:Capabilities xmlns:wrs="http://www.opengis.net/cat/wrs/1.0" xmlns:csw="http://www.opengis.net/cat/csw" xmlns:ogc="http://www.opengis.net/ogc" xmlns:ows="http://www.opengeospatial.net/ows" xmlns:xlink="http://www.w3.org/1999/xlink" version="1.0.0">
注意 REQUEST 中的 OWS 模式命名空间如何指向 http://www.opengis.net/ows
虽然响应指向 http://www.opengeospatial.net/ows
两个命名空间必须相同,.NET 才能反序列化数据。所以你可以让响应响应正确的命名空间。在我的例子中,由于我无法控制 Java Web 服务,我不得不修改自动生成的代理类并替换“xmlns:ows=http://www.opengis.net/ows”的所有实例对于“xmlns:ows=http://www.opengeospatial.net/ows”
