[英]WCF namespace prefix
我正在尝试使用第三方提供程序提供的我认为是较旧样式的ASMX Web服务,但是要使用WCF,因为这是较新样式应用程序的推荐方法。
将服务引用作为Web引用添加到应用程序时(单击“添加服务引用”对话框中的“高级”按钮,然后选择“添加Web引用”),我可以成功使用Web服务。 一切正常。 但是,据我了解,这是设置Web服务的较旧样式的方法。
我想要通过WCF进行操作,所以我添加了一个服务引用,而没有将其作为Web引用(例如,“添加服务引用”对话框,输入地址并单击“转到”)。 我所有与Web服务交谈的代码似乎都可以正常工作,但是我不断收到以下异常:
System.ServiceModel.CommunicationException was unhandled by user code

InnerException:
我玩过提琴手,它看起来像一个简单的名称空间问题,我不确定如何解决。 这是在将服务设置为Web参考时起作用的消息:
<?xml version="1.0" encoding="utf-8"?>
<soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/"
xmlns:soapenc="http://schemas.xmlsoap.org/soap/encoding/"
xmlns:tns="urn:webservices2_0_0"
xmlns:types="urn:webservices2_0_0/encodedTypes"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:xsd="http://www.w3.org/2001/XMLSchema">
<soap:Body soap:encodingStyle="http://schemas.xmlsoap.org/soap/encoding/">
<tns:readCompany>
<auth href="#id1" />
</tns:readCompany>
<tns:WSAuthentication id="id1" xsi:type="tns:WSAuthentication">
<api_key xsi:type="xsd:string">myApiKey</api_key>
<code xsi:type="xsd:string">myCode</code>
<keyword xsi:type="xsd:string">myKeyword</keyword>
<password xsi:type="xsd:string">myPassword</password>
<username xsi:type="xsd:string">myUsername</username>
</tns:WSAuthentication>
</soap:Body>
</soap:Envelope>
这是将服务设置为仅服务参考(而不是Web参考)时不会出现的情况:
<s:Envelope xmlns:s="http://schemas.xmlsoap.org/soap/envelope/">
<s:Body s:encodingStyle="http://schemas.xmlsoap.org/soap/encoding/"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:xsd="http://www.w3.org/2001/XMLSchema">
<q1:readCompany xmlns:q1="urn:webservices2_0_0">
<auth href="#id1"/>
</q1:readCompany>
<q2:WSAuthentication id="id1" xsi:type="q2:WSAuthentication" xmlns:q2="urn:webservices2_0_0">
<api_key xsi:type="xsd:string">myApiKey</api_key>
<code xsi:type="xsd:string">myCode</code>
<keyword xsi:type="xsd:string">myKeyword</keyword>
<password xsi:type="xsd:string">myPassword</password>
<username xsi:type="xsd:string">myUserName</username>
</q2:WSAuthentication>
</s:Body>
</s:Envelope>
显然,除了命名空间之外,这两个消息之间还存在差异,但是我在提琴手中要做的就是将不起作用的消息拿走,然后将所有s:命名空间更改为soap :,然后一切正常。 因此,我很确定我所要做的就是像使用fiddler一样更改名称空间,这应该可以在WCF中使用,但是我不确定如何做到这一点。
您应该尝试使用svcutil命令行工具(打开VS Command Prompt来运行它),尽管它与VS的参考功能相似,但实际上是完全不同的代码库。 您可以使用它生成代理,所有客户端类型等,就像使用服务引用功能一样,它非常可靠。
