.NET中的SOAP请求
我们正在尝试使用SOAP请求使用Visual Studio C＃与预订API进行交互。
我们已经与另一个API的Web服务接口而没有问题，但这个问题certificate是有问题的。
我们已将其添加为服务引用，并且Visual Studio已为其生成所有类和web.config条目，以便一切看起来都很好。
但是，当我们尝试向客户端SOAP服务发出简单请求时，我们会收到以下错误：
rpc \ literal SOAP不支持Namespace =’com.hrs.soap.hrs’。 包装元素必须是不合格的。
代码是：
PingRequest pingrequest = new PingRequest(); SoapServiceClient service = new SoapServiceClient(); service.ping(pingrequest); 这是Web.config文件中添加的内容：
根据文档，请求应如下所示：
完整堆栈跟踪如下：

我们安装了Fiddler并且没有我们可以看到的XML请求，大概是因为它在发送任何内容之前抛出exception。
我们在设置中需要更改什么来使其工作？
UPDATE
WSDL：可用[这里] [1]
UPDATE
根据davidfmatheson的出色建议，我在本地复制了WSDL并按照建议进行了修改。 尽管可能在不同的地方，我仍然会得到同样的错误：
[System.ComponentModel.EditorBrowsableAttribute(System.ComponentModel.EditorBrowsableState.Advanced)] BLL.HRSService.pingResponse BLL.HRSService.HRSSoapService.ping(BLL.HRSService.pingRequest request) { return base.Channel.ping(request); } public BLL.HRSService.HRSPingResponse ping(BLL.HRSService.HRSPingRequestWrapper ping1) { BLL.HRSService.pingRequest inValue = new BLL.HRSService.pingRequest(); inValue.ping = ping1; BLL.HRSService.pingResponse retVal = ((BLL.HRSService.HRSSoapService)(this)).ping(inValue); return retVal.pingResponse1; }
失败的行是返回base.Channel.ping（request）; 错误命名空间=’com.hrs.soap.hrs’不受rpc \ literal SOAP支持。 包装元素必须是不合格的。
我还尝试显式设置SOAPBinding：
Exception Details: System.InvalidOperationException: Namespace='com.hrs.soap.hrs' is not supported with rpc\literal SOAP. The wrapper element has to be unqualified. Source Error: Line 15917: [System.Web.Services.Protocols.SoapDocumentMethod(Use = System.Web.Services.Description.SoapBindingUse.Literal)] Line 15918: BLL.HRSService.pingResponse BLL.HRSService.HRSSoapService.ping(BLL.HRSService.pingRequest request) { Line 15919: return base.Channel.ping(request); Line 15920: } Line 15921:
好了，现在我已经将SOAP Binding样式修改为在本地WSDL中记录并重新创建了类，我有一个不同的错误：

请求终于发了！
Fiddler为PING显示以下内容：
.........Hello HRS
您正在尝试从.NET使用RPC-literal服务，因此您可能必须将服务转换为doc-literal。 请参阅MSDN博客 。
编辑：更完整的答案
目标是能够使用doc-literal，但仍然发送相同的消息。 让我们关注ping操作。 现在你的WSDL的类型定义为：
并且您的消息定义为：
你的绑定定义为：
所以在本地我们将“rpc”更改为“document”，然后将WSDL修复为实际的document / literal：
...
现在生成此WSDL并查看它是否发送ping请求。 如果您没有修复响应结构，它可能无法理解返回的内容，但您至少应该看到通过网络发送的请求。 您可以使用SoapUI加载两个WSDL并查看生成的请求类型。 目标是发送相同的请求，只使用document / literal而不是rpc / literal。
