WCF 服务异常"The HTTP request is unauthorized with client authentication scheme"



我在客户端处理来自外部供应商wcf服务(如"The HTTP request is unauthorized with client authentication scheme 'Basic'. The authentication header received from the server was 'Basic realm="CASM"'".)的异常我请求Web服务提供大量数据,但在某个时间点我遇到了异常。中间的事情是,我从wcf服务中获得了一些数据,然后得到了异常。所以我认为我是否需要对请求进行微调??所以我不应该一次询问大量数据,或者这是一个不同的问题。我确实很喜欢"在VS2012中添加web服务引用时出错"的帖子,但运气不好。有人能告诉我,这一例外背后可能的原因是什么吗。下面是我的webconfig部分,我正在起诉我的代码中的用户名和密码

<binding name="Test" closeTimeout="00:01:00" openTimeout="00:01:00"
      receiveTimeout="00:10:00" sendTimeout="00:01:00" allowCookies="false"
      bypassProxyOnLocal="false" hostNameComparisonMode="StrongWildcard"
      maxBufferSize="6553600" maxBufferPoolSize="524288" maxReceivedMessageSize="6553600"
      messageEncoding="Text" textEncoding="utf-8" transferMode="Buffered"
      useDefaultWebProxy="true">
      <readerQuotas maxDepth="32" maxStringContentLength="8192" maxArrayLength="16384"
        maxBytesPerRead="4096" maxNameTableCharCount="16384" />
      <security mode="TransportCredentialOnly">
        <transport clientCredentialType="Basic" proxyCredentialType="Basic"
          realm="" />
        <message clientCredentialType="UserName" algorithmSuite="Default" />
      </security>
    </binding>
  <endpoint address="http://testurl/as" binding="basicHttpBinding"
    bindingConfiguration="Test" contract="Testservice.Test" name="Test">
  </endpoint>

更新

还有一件事,这个realm="CASM"是什么异常,我无法在客户端配置中设置,intellisense没有给出

尝试更改此

 <security mode="TransportCredentialOnly">
    <transport clientCredentialType="Basic" proxyCredentialType="Basic"
      realm="" />
    <message clientCredentialType="UserName" algorithmSuite="Default" />
  </security>

使用这条线路

<security mode="TransportCredentialOnly">
   <transport clientCredentialType="Anonymous"/>
   <message clientCredentialType="UserName" algorithmSuite="Default"/>
</security>
