Xamarin Android：SOAP Web服务失败（401 Unauthorized）但我的证书是正确的

Question

Xamarin.Android中的错误

我收到以下错误：

  

{System.Net.WebException：请求失败，HTTP状态为401：   未经授权的   System.Web.Services.Protocols.SoapHttpClientProtocol.ReceiveResponse   （System.Net.WebResponse响应，   System.Web.Services.Protocols.SoapClientMessage消息，   System.Web.Services.Protocols.SoapExtension [] extensions）[0x00055] in   /Users/builder/data/lanes/3511/77cb8568/source/mono/mcs/class/System.Web.Services/System.Web.Services.Protocols/SoapHttpClientProtocol.cs:273   在System.Web.Services.Protocols.SoapHttpClientProtocol.Invoke   （System.String method_name，System.Object [] parameters）[0x000b8] in   /Users/builder/data/lanes/3511/77cb8568/source/mono/mcs/class/System.Web.Services/System.Web.Services.Protocols/SoapHttpClientProtocol.cs:365   在DSPFood.Droid.SOAP.scan.ShipGetNewBatchCode（System.String   scanID）[0x00001]在C：\ Projects \ Projecten \ DSP中   食品\解决方案\ DSPFood \ DSPFood \ DSPFood.Droid \ WEB   引用\ SOAP \ Reference.cs：389 at（包装器   远程-调用，以检查）   DSPFood.Droid.SOAP.scan：ShipGetNewBatchCode（string）at   DSPFood.Droid.DependencyServices.SoapService + d__13.MoveNext   （）[0x00057]在C：\ Projects \ Projecten \ DSP中   食品\解决方案\ DSPFood \ DSPFood \ DSPFood.Droid \ DependencyServices \ SoapService.cs：290   }

控制台应用程序中的工作代码

但是当我在控制台应用程序中运行以下代码时，它可以工作：

static void Main(string[] args)
{
    var nc = new NetworkCredential("**", "**");
    var soapClient = new SOAP.scan();

    soapClient.UseDefaultCredentials = true;
    soapClient.Credentials = nc;
    var response = soapClient.ProdGetNewBatchCode("");
}

  

回复：“A000000086”

Xamarin

public string ShipGetNewBatchCode(string macAddress)
{
    var retValue = "";

    try
    {
        var nc = new NetworkCredential("**", "**");
        var soapClient = new SOAP.scan();

        soapClient.UseDefaultCredentials = true;
        soapClient.Credentials = nc;
        var response = soapClient.ProdGetNewBatchCode("");
    }
    catch (Exception ex)
    {
        throw ex;
    }

    return retValue;
}
