我是网络服务和C#的新手,所以如果我的问题太简单,请原谅我。我已经四处搜索但找不到答案 - 至少有一个基于我的关键字。
我正在尝试通过C#(Visual Web Developer 2010 Express)调用Web服务,但我收到错误作为响应。当我通过soapUI调用相同的Web服务时,我没有收到错误。当我将来自C#的SOAP请求与来自soapUI的SOAP请求进行比较时,C#SOAP请求缺少故意为空的参数<aclObjectId>
。当我从soapUI请求中取出空参数时,我得到了同样的错误。对我来说,答案是让C#发送参数,即使它是空的。我通过将其设置为null或“”来尝试此操作,但无济于事。有没有办法强制我的C#Web服务客户端发送一个空参数,或者可能发送所有参数,即使它们没有值?

答案 0 :(得分:4)
首先,您可以尝试将aclObjectId
属性声明为序列化,即使它是null
。为此,您需要找到class ACLUsersRequest
的定义并添加
[System.Xml.Serialization.XmlElementAttribute(IsNullable=true)]
该财产。
这将把它作为<aclObjectId xsi:nil="true" />
其次,您可以简单地将该属性声明为string.Empty
:
EDRSearchServiceSOAPImplClient client = new EDRSearchServiceSOAPImplClient();
var test = client.getACLUsers(
new ACLUsersRequest() {
aclName = "my_acl",
docbase = "qwe",
aclObjectId=string.Empty },//this should do the trick
new UserCredentials() {
userName = "lala",
password = "123",
docbase = "qwe" });
将其作为<aclObjectId />
包含在SOAP请求中,等于<aclObjectId></aclObjectId>
如果两种方法都不起作用,那么您正在处理非常糟糕的Web服务提供商,并且需要实现自编写的客户端,将客户端强制格式化消息。
答案 1 :(得分:0)
到目前为止,我唯一能找到的东西是:
http://www.w3.org/TR/2007/REC-soap12-part2-20070427/
4.2.1
Applications MAY process invocations with missing parameters but also MAY fail to process the invocation and return a fault.
您是否手动生成了网络参考?你能提供合适的WSDL吗? +我可以更新这个答案
<operation name="getACLUsers">
<soap:operation soapAction=""></soap:operation>
<input>
<soap:body use="literal"></soap:body>
</input>
<output>
<soap:body use="literal"></soap:body>
</output>
</operation>
对我而言,这看起来并不像SOAP级别有多个参数,只是说XML或字符串参数。 getAclUsers有多个参数吗?
我承认我的SOAP知识有限,但WSDL中没有任何内容列出任何参数......也许您正在序列化XML并且XML序列化选项是您应该看的内容?
