Java 让Ksoap2客户端与基于PHP的Web服务对话时出现问题

我在让PC和Android上的ksoap2客户端与PHP Web服务正常对话时遇到问题。我试过PHP的包含库和nusoap，但没有一个是有效的

忘记错误。Android和PC客户端都提供org.xmlpull.v1.XmlPullParserException 但信息是不同的。例如，PC不能以xml开头

这是我的电脑客户端的代码

import org.ksoap2.SoapEnvelope;
import org.ksoap2.serialization.SoapObject;
import org.ksoap2.serialization.SoapSerializationEnvelope;
import org.ksoap2.transport.*;

public class client {



    public static void main(java.lang.String args[]) {
        final String SOAP_ACTION = "http://secure.g4apps.com/submitAxios/writegpsdata";
        final String METHOD_NAME = "writegpsdata";
        final String NAMESPACE = "http://secure.g4apps.com/submitAxios/";
        final String URL = "http://secure.g4apps.com/submitAxios.php";

        SoapObject rpc = new SoapObject(NAMESPACE,METHOD_NAME);
        SoapSerializationEnvelope env = new SoapSerializationEnvelope(SoapEnvelope.VER11);
        rpc.addProperty("writegpsdataRequest","A1,E1,E1,AT333AT333,9055627513,2012-02-02 02:02:02,2012-02-02 02:02:02,-454545.343434,434343.232323,A334A334A334A443X,1000000,3434");


        env.bodyOut=rpc;
        env.encodingStyle = SoapSerializationEnvelope.XSD;

        HttpTransportSE ht = new HttpTransportSE(URL);
        ht.debug = true;

        try {
            ht.call(SOAP_ACTION, env);

            System.out.println(ht.requestDump);

        }
        catch(org.xmlpull.v1.XmlPullParserException ex2) {
            System.out.println("Error" + ex2.toString() );
        }
        catch (Exception ex){
            String error = ex.toString();
            System.out.println("Error: "+ error);
        }


    }
}

这是我的PHP服务器代码。存在通信writegpsdata函数，但服务器响应上的客户端错误

<?php
// submitGPS is a soap server which writes GPS data to a mysql database.
// requires the writegpsdata.inc file which contains the required function
// uses submitGPS.wsdl file for defining soap service

require_once ("writegpsdata.axios.inc.php");
//require_once ("lib/nusoap.php");

ini_set("soap.wsdl_cache_enabled","0"); //disabling WSDL caching
$server = new SoapServer("http://secure.g4apps.com/submitAxios.wsdl");
$server->AddFunction("writegpsdata");
$server->handle();
?>

为了更好地衡量，这里是wsdl文件

<?xml version="1.0"?>
<wsdl:definitions xmlns:soap="http://schemas.xmlsoap.org/wsdl/soap/" xmlns:tns="http://secure.g4apps.com/submitAxios/" xmlns:wsdl="http://schemas.xmlsoap.org/wsdl/" xmlns:xsd="http://www.w3.org/2001/XMLSchema" name="submitAxios" targetNamespace="http://secure.g4apps.com/submitAxios/">

事实证明，我的include函数writegpsdata有一些额外的字符作为或结束（在php标记之外），这在eclipse中是看不到的。我复制了内容，删除了文件并将其粘贴到一个新文件中，并在删除时删除了此错误。尽管我的android客户端仍然有问题。稍后我可能会发布另一个问题
