1 android soap web-services .net-4.0
我试过跟踪每个谷歌如何做到这一点,但我收到错误
android无法在没有有效动作参数的情况下处理请求.请提供有效的肥皂行动
我的网络服务完成是.net 4.0我有一个在端口9022上的asmx,这是我的asmx

任何帮助都会很精彩!
解决方案1:
您声明I have an asmx that is on port 9022但在您的代码中您使用的是9020
private String NAMESPACE = "http://example.net:9020/";
private String SOAP_ACTION = "http://example.net:9020/InsertComment";
private String URL="http://example.net:9020/Math.asmx?";
解决方案2:
2.1编辑代码:
除掉 "？" 来自您的URL变量
private String URL="http://example.net:9020/Math.asmx?";
2.2编辑代码:
SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(SoapEnvelope.VER11);
代替 SoapEnvelope.VER12
2.3编辑代码:
SoapObject resultRequestSOAP = null; 和 resultRequestSOAP = (SoapObject) envelope.getResponse();
而不是Object resultRequestSOAP = null;和resultRequestSOAP = (Object) envelope.getResponse();
2.4编辑代码:
HttpTransportSE androidHttpTransport = new HttpTransportSE(URL,60000);
代替 HttpTransportSE androidHttpTransport = getHttpTransportSE();
解决方案3:
我编辑并尝试了这个修改后的代码版本:
private String URL="http://example.net:9020/Math.asmx";
//...
//Object resultRequestSOAP = null;
public void onClick(View v) {
new Thread() {
@Override
public void run() {//Create request
//Variables
SoapObject request = new SoapObject(NAMESPACE, METHOD_NAME);
//Use this to add parameters - reactivate this line bellow to match your needs after testing this at first
//request.addProperty("NewComment", "cell");
//Could also try the following instead of the line bellow //SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(SoapEnvelope.VER12); //envelope.dotNet = true; //envelope.setOutputSoapObject(request);
SoapSerializationEnvelope envelope = getSoapSerializationEnvelope(request);
HttpTransportSE androidHttpTransport = new HttpTransportSE(URL,60000);
//if does not work you may decommand the line bellow
//androidHttpTransport.debug = true;
try {
androidHttpTransport.call(SOAP_ACTION, envelope);
SoapObject resultRequestSOAP = (SoapObject)envelope.bodyIn;
} catch (Exception e) {
Log.w("myApp", e.getMessage());
Log.w("myApp", e.getCause());
}
}
}.start();
}
代替
private String URL="http://example.net:9020/Math.asmx?";
//...
Object resultRequestSOAP = null; //this line should not be here
public void onClick(View v) {
//...
}
解决方案4:
检查/重置您的Web服务asmx和端口9022.
