ksoap2-android访问webservice，当…

ksoap2-android是在android平台，访问webservice的外部jar包。

       项目遇到的bug如下：当手机使用wifi或者net访问webservice的时候一切正常，但是当手机网络为wap的情况下，就连接失败。

       解决办法：ksoap2-android最新版本是2.5.4。在2.5.2之前源码都是不支持代理访问的，在2.5.4之后，源码增加了对网络有代理的支持。

       下面把主要代码贴出来：

//判断当前网络是否是net，true为net，false为wap  

public static boolean isGprsNet(){  

    String proxyHost = android.net.Proxy.getDefaultHost();  

    return proxyHost==null;  

}  

  

//根据网络类型返回相应的HttpTransportSE  webservice用  

public static HttpTransportSE getHttpTransportSE(Context context){  

    HttpTransportSE ht;  

    if(!HttpUtil.isGprsNet()){  

        java.net.Proxy p = new java.net.Proxy(java.net.Proxy.Type.HTTP,new InetSocketAddress(android.net.Proxy.getDefaultHost(),android.net.Proxy.getDefaultPort()));  

        ht=new HttpTransportSE(p,context.getString(R.string.wsurl));  

    }else{  

        ht = new HttpTransportSE(context.getString(R.string.wsurl));  

    }  

    return ht;  

}  

  

public String login(Context context,String phoneNumber,String pwd){  

    SoapObject request = new SoapObject(context.getString(R.string.namespace), "login");  

    request.addProperty("usrPhone", phoneNumber);  

    request.addProperty("passWord", pwd);  

    SoapSerializationEnvelope envelope = new SoapSerializationEnvelope( SoapEnvelope.VER11 );  

    envelope.bodyOut=request;  

    HttpTransportSE ht = HttpUtil.getHttpTransportSE(context);  

    try {  

        ht.call(null, envelope);  

    } catch (Exception e) {}   

    SoapObject so = null;  

    so = (SoapObject) envelope.bodyIn;  

    String result= so.getProperty("return").toString();  

    return result;  

}

     androi下net和wap自适应代码：

private HttpURLConnection getURLConnection(String url) throws Exception {       

          String proxyHost = android.net.Proxy.getDefaultHost();       

          if (proxyHost != null) {       

              java.net.Proxy p = new java.net.Proxy(java.net.Proxy.Type.HTTP,       

                      new InetSocketAddress(android.net.Proxy.getDefaultHost(),       

                              android.net.Proxy.getDefaultPort()));       

        

              return (HttpURLConnection) new URL(url).openConnection(p);       

         

         } else {       

             return (HttpURLConnection) new URL(url).openConnection();       

         }       

     }
