在 PHP 中通过 Soap 调用 C# Windows 服务的soapURL

Question

问题：

我继承了一个使用 PHP 调用 C# windows 服务的软件。它不能正常工作，所以我才刚刚开始使用 WCF 和 SOAP。

我的主要问题是我无法使用 PHP 和 Soap 调用 Windows 服务。当我尝试它时，PHP 崩溃了。

我完成了微软教程： https://docs.microsoft.com/en-us/dotnet/framework/wcf/getting-started-tutorial 当我按照教程中的描述使用 C# 客户端时，一切都像魅力一样工作。我添加了一个安装程序以使整个程序可作为 Windows 服务使用。长话短说，在 C# 中一切正常。

我假设它只是没有为 SOAP 调用正确配置。我已经通读了：http://www.rizalalmashoor.com/blog/calling-a-wcf-service-from-php/，但我仍然无法运行它。

问题：

源代码在下面。我想先提出我的问题：

1）我在基地址公开服务，对吧？？

http://localhost:1234/GettingStartedLib/CalculatorService

2) http 端点为空。 PHP 代码中的soapURL 是否正确？

3) 有没有办法调试soap 调用？即使我在 ZendStudio 中将它作为 CLI 应用程序进行调试，我也没有得到任何进一步的信息。

如果需要或解释不充分，我很乐意提供更多信息。

• 在有人回答之前：在 php.ini 中启用了 Soap。已经检查过了。

源码：

PHP：

$soapURL = 'http://localhost:1234/GettingStartedLib/CalculatorService?wsdl';
$soapAttributes = array('soap_version' => SOAP_1_1);

$result = new SoapClient($soapURL, $soapAttributes);

WCF库的配置：

C# 接口

namespace GettingStartedLib
{
    [ServiceContract(Namespace = "http://Microsoft.ServiceModel.Samples")]
    public interface ICalculator {
        [OperationContract]
        double Add(double n1, double n2);
        [OperationContract]
        double Subtract(double n1, double n2);
        [OperationContract]
        double Multiply(double n1, double n2);
        [OperationContract]
        double Divide(double n1, double n2);
        [OperationContract]
        string SoapCall();
    }
}

C# 服务本身：

namespace GettingStartedLib
{
    public class CalculatorService : ICalculator
    {
        public double Add(double n1, double n2) {
            double result = n1 + n2;
            Console.WriteLine("Received Add({0},{1})", n1, n2);
            // Code added to write output to the console window.  
            Console.WriteLine("Return: {0}", result);
            return result;
        }

        public double Subtract(double n1, double n2) {
            double result = n1 - n2;
            Console.WriteLine("Received Subtract({0},{1})", n1, n2);
            Console.WriteLine("Return: {0}", result);
            return result;
        }

        public double Multiply(double n1, double n2) {
            double result = n1 * n2;
            Console.WriteLine("Received Multiply({0},{1})", n1, n2);
            Console.WriteLine("Return: {0}", result);
            return result;
        }

        public double Divide(double n1, double n2) {
            double result = n1 / n2;
            Console.WriteLine("Received Divide({0},{1})", n1, n2);
            Console.WriteLine("Return: {0}", result);
            return result;
        }
        public string SoapCall() => "SoapCall";
    }
}

Answer 1

解决了这个问题。我必须输入

<baseAddresses><add baseAddress="localhost:1234/GettingStartedLib/CalculatorService.vsc"/>
</baseAddresses>

由于我将http端点的地址留空，所以soap URL是localhost:1234/GettingStartedLib/CalculatorService.vsc?wsdl
