java.net.SocketException: Permission denied in Android Studio with Visual Studio 2017 Web Service

我在Android Studio中使用KSOAP2库，在SQL SERVER中使用＆＃34; Clientes＆＃34; Visual Studio 2017中的表和Web服务ASP.NET。

AndroidManifest：

    <?xml version="1.0" encoding="utf-8"?>

执行＆＃34; TareaWSConsulta＆＃34;时出现下一个错误：

java.io.IOException: HTTP request failed, HTTP status: 400

NAMESPACE，URL，METHOD_NAME和SOAP_ACTION是正确的...知道问题应该是什么？谢谢！

Answer 1

transporte.call(SOAP_ACTION, envelope);// error here 
SOAPAction: "http://tempuri.org/UpdateNotificationToken" // soap action like that and you using 
 String SOAP_ACTION="ruperdevcoder/NuevoClienteSimple"; //change this 

您可以从asmx文件中获取soap操作

    POST /Services/apk_Driver.asmx HTTP/1.1
Host: redrive.orataro.com
Content-Type: text/xml; charset=utf-8
Content-Length: length
 SOAPAction: "http://tempuri.org/UpdateNotificationToken"

     <?xml version="1.0" encoding="utf-8"?>
    <soap:Envelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">
      <soap:Body>
        <UpdateNotificationToken xmlns="http://tempuri.org/">
          <DriverID>string</DriverID>
          <CompanyID>string</CompanyID>
          <NotificationToken>string</NotificationToken>
          <DeviceType>string</DeviceType>
        </UpdateNotificationToken>
      </soap:Body>
    </soap:Envelope>

Answer 2

My NAMESPACE是“ruperdevcoder”，WebMethod的SOAPACTION是“ruperdevcoder / ListadoClientes”：

POST /ServicioClientes.asmx HTTP/1.1
Host: localhost
Content-Type: text/xml; charset=utf-8
Content-Length: length
SOAPAction: "ruperdevcoder/ListadoClientes"

<?xml version="1.0" encoding="utf-8"?>
<soap:Envelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">
  <soap:Body>
    <ListadoClientes xmlns="ruperdevcoder" />
  </soap:Body>
</soap:Envelope>
HTTP/1.1 200 OK
Content-Type: text/xml; charset=utf-8
Content-Length: length

<?xml version="1.0" encoding="utf-8"?>
<soap:Envelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">
  <soap:Body>
    <ListadoClientesResponse xmlns="ruperdevcoder">
      <ListadoClientesResult>
        <Cliente>
          <Id>int</Id>
          <Nombre>string</Nombre>
          <Telefono>int</Telefono>
        </Cliente>
        <Cliente>
          <Id>int</Id>
          <Nombre>string</Nombre>
          <Telefono>int</Telefono>
        </Cliente>
      </ListadoClientesResult>
    </ListadoClientesResponse>
  </soap:Body>
</soap:Envelope>
