Question

我想将数据发送到WebService，但它没有返回有效的反馈，并在String上显示错误。我正在使用KSOAP2。

<小时/> 当我调试时，我收到以下消息：

已收集对象无法评估org.ksoap2.serialization.SoapObject.toString（）

如果一切正常，它应该回答我'OK'，但WebService返回一个XML（responseDump）：

＆LT; ？xml version =“1.0”encoding =“utf-8”？＆gt;＆lt; soap：Envelopexmlns：soap =“http://schemas.xmlsoap.org/soap/envelope/”xmlns：xsi =“http://www.w3.org/2001/XMLSchema-instance”xmlns：xsd =“http： //www.w3.org/2001/XMLSchema"><皂：Faultsoap：服务器16; /＆的faultcode LT; faultstring＆gt; System.Web.Services.Protocols.SoapException：服务器无法处理请求。 ---＆gt; System.InvalidOperationException： CommandText属性尚未初始化。 在System.Data.OracleClient.OracleClient.OracleClient.OracleClient.OracleClient.OracleClmand.OracleClient.OracleClmand.OracleClient.Oracle上的System.Data.OracleClient.OracleClmand.get_StatementText（）处于System.Data.OracleClient.OracleCommand.Execute（OciStatementHandle statementHandle，CommandBehavior behavior，Boolean needRowid，OciRowidDescriptor＆amp; rowidDescriptor，ArrayList＆amp; resultParameterOrdinals）（布尔值needRowid，OciRowidDescriptor＆amp; rowidDescriptor）位于MettaWebService.BancoDados.executaComando（String查询）的System.Data.OracleClient.OracleCommand.ExecuteNonQuery（），位于mobPrev_SAP.wsvmetta.EnviarDados（字符串查询）的MettaWebService.MettaServicos.EnviarDados（字符串查询）在c：\ Users \ Deivite \ AppData \ Local \ Temp \ Compilacao \ wsvMetta_Eng \ wsvmetta.asmx.cs：第65行--- 内部异常堆栈跟踪结束 ---

以下是发送和接收WebService的代码：

public String transmitWS(String col_numero, String qtd_consumo, String idate_itime, String vlr_med,
                         String cod_valor, String matric, String texto_obs, String observacao,
                         String idProgramacao){
    String HOST = "";
    String NAMESPACE = "";
    String URL = "";              //all right here
    String SOAP_ACTION = "";
    String METHOD_NAME = "";

    String resultWS = null;

    SoapObject requestTransmit = new SoapObject(NAMESPACE, METHOD_NAME);
    PropertyInfo transmitPI = new PropertyInfo();
    transmitPI.setType(String.class);
    transmitPI.setName("Query");
    transmitPI.setValue("update prev_programacao set col_numero = " + col_numero + ", status_ponto = 3, qtd_consumo =" + qtd_consumo + "," +
            " idate_itime = TO_DATE('"+ idate_itime +"','YYYY-MM-DD HH24:MI:SS'), vlr_med = " + vlr_med + ", cod_valor = " + cod_valor +
            ", matric = " + matric +", texto_obs = '" + texto_obs + "', observacao = '" +
            observacao + "' where id_programacao = "+idProgramacao+"");
    requestTransmit.addProperty(transmitPI);
    SoapSerializationEnvelope envelopeTransmit = new SoapSerializationEnvelope(SoapEnvelope.VER11);
    envelopeTransmit.dotNet = true;
    envelopeTransmit.setAddAdornments(false);
    envelopeTransmit.implicitTypes = false;
    envelopeTransmit.setOutputSoapObject(requestTransmit);
    HttpTransportSE androidHttpTransportTransmit = new HttpTransportSE(URL);
    //AndroidHttpTransport androidHttpTransport = new AndroidHttpTransport(URL);
    try {
        androidHttpTransportTransmit.debug = true;
        androidHttpTransportTransmit.call(SOAP_ACTION, envelopeTransmit);
        SoapObject responseTransmit = (SoapObject) envelopeTransmit.getResponse();
        resultWS = androidHttpTransportTransmit.requestDump;
        resultWS = androidHttpTransportTransmit.responseDump;

        Log.i("t", "doInBackground");
    } catch (Exception e) {
        e.printStackTrace();
    }
    return resultWS;
}

最后，resultWS为null。 是否有人知道此错误的原因？

我无法检测到什么是错的，但这里是一个使用ksoap的工作函数。也许它会有所帮助：

    /**
 * Calls the stored proc on the server to return a dataset/SoapObject. This will always run the ProcReader method on the web server.
 * 
 * @param storedProc The Stored Proc to call
 * @param params The parameter(s) for the stored proc (pipe seperated for multiple parameters)
 * @return The SoapObject returned by the Stored Proc call
 * @throws Exception
 */
public static SoapObject callProcServiceForObject(String serviceMethod, String storedProc, String params) throws Exception {
    String NAMESPACE = "http://" + GlobalVars.serviceIP + "/";
    String METHOD_NAME = getMethodName(serviceMethod);
    String SOAP_ACTION = NAMESPACE + METHOD_NAME;
    String URL = "http://" + GlobalVars.serviceIP + "/ATService.asmx";
    SoapObject request = new SoapObject(NAMESPACE, METHOD_NAME);

    if (GlobalVars.encryptedService) {
        request.addProperty("ePassword", CryptUtil.encryptString(GlobalVars.deviceSerialNumber));
        request.addProperty("eData", CryptUtil.encryptString(GlobalVars.serverDB));
        request.addProperty("eSP_Name", CryptUtil.encryptString(storedProc));
        request.addProperty("eParam", CryptUtil.encryptString(params));
    } else {
        request.addProperty("sPassword", GlobalVars.deviceSerialNumber);
        request.addProperty("sData", GlobalVars.serverDB);
        request.addProperty("sSP_Name", storedProc);
        request.addProperty("sParam", params);
    }
    SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(SoapEnvelope.VER11);

    // Enable the below property if consuming .Net service
    envelope.dotNet = true;
    envelope.setOutputSoapObject(request);
    HttpTransportSE androidHttpTransport = new HttpTransportSE(URL, timeout);
    //count up the network traffic
    numberOfBytesTransmitted = numberOfBytesTransmitted + StringToBytes(request.toString());

    SoapObject returnable = null;
    try {
        androidHttpTransport.call(SOAP_ACTION, envelope);
        returnable = (SoapObject)envelope.getResponse();
    } catch (Exception e) {
        e.printStackTrace();
        throw new Exception("Msg:" + e.getMessage() + "; SP:" + storedProc + "; Params: " + params + "; Method:" + METHOD_NAME);
    }
    numberOfBytesTransmitted = numberOfBytesTransmitted + StringToBytes(returnable.toString());
    return returnable;
}

Web Service不适用于Android应用程序
