asp.net – SOAP 1.2在SOAP 1.1工作时产生错误请求

我创建了一个ASP.NET Web服务(asmx),允许第三方软件连接到我的解决方案.
当从服务器所驻留的服务器调用时,使用SOAP 1.1或ASP.NET的调用表调用web服务时效果很好.

那么问题是什么,连接方只支持SOAP 1.2,当使用SOAP 1.2调用web服务时,它返回400 Bad请求.

我在web.config中启用了SOAP 1.2：

<configuration>
    <system.web>
        <webServices>
            <soapExtensionTypes>
                <add type="Microsoft.Web.Services2.WebServicesExtension,Microsoft.Web.Services2,Version=2.0.0.0,Culture=neutral,PublicKeyToken=31bf3856ad364e35" priority="1" group="0" />
            </soapExtensionTypes>
            <protocols>
                <add name="HttpSoap12" />
                <add name="HttpGet" />
                <add name="HttpPost" />
            </protocols>
        </webServices>
    </system.web>
</configuration>

我将扩展用于另一部分,我试图通过特定于位置的配置禁用它,但是没有产生任何结果.

我启用了跟踪：

<system.diagnostics>
    <trace autoflush="true" />
    <sources>
        <source name="System.Web.Services.Asmx">
            <listeners>
                <add name="AsmxTraceFile" type="System.Diagnostics.TextWriterTraceListener" initializeData="D:Trace.log" traceOutputOptions="LogicalOperationStack,DateTime,Timestamp,ProcessId,ThreadId" />
            </listeners>
        </source>
    </sources>
    <switches>
        <add name="System.Web.Services.Asmx" value="Verbose"  />
    </switches>
</system.diagnostics>

使用Chrome Advanced Rest Client我发送以下请求：

<?xml version="1.0" encoding="utf-8"?>
<soap12:Envelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:soap12="http://www.w3.org/2003/05/soap-envelope">
  <soap12:Body>
    <authenticateUser xmlns="http://services.kvh.nl/foo">
      <username>kvh</username>
      <password></password>
    </authenticateUser>
  </soap12:Body>
</soap12:Envelope>

这导致400错误请求和跟踪日志中的以下条目：

我已经用谷歌搜索了近乎精神错乱,但不幸的是我无法找到解决方案.

很感谢任何形式的帮助.

编辑：

不幸的是,rAhuID的建议删除了SOAP 1.1支持,但这并没有解决问题.我继续尝试了一些选项,例如清除所有协议,只添加HttpSoap12和文档,这看起来更糟糕.然后我删除了所有不需要的协议. XmlException从日志中消失,但我仍然收到400 Bad请求:(

我已经从本地计算机(使用hosts文件,因此我可以使用正确的主机名)进行测试,以排除代理服务器的问题.

Currrent web.config：

<protocols>
    <!--
        <clear />
        <add name="Documentation" />
        <add name="HttpSoap12" />
    -->
    <remove name="HttpGet" />
    <remove name="HttpPost" />
    <remove name="HttpPostLocalhost" />
    <remove name="HttpSoap" />
</protocols>

解决方法

尝试指定“AnyHttpSoap”而不是“HttpSoap12”.

或者如你所说,如果他们只支持1.2,那么只需从协议中删除“HttpSoap”,而不是添加“HttpSoap12”.

<protocols>
  <remove name="HttpSoap"/>
</protocols>

This可能有所帮助.
