使用KSoap2从Android到.net WebServer的SOAP调用

Question

今天是个好日子。

我正在尝试对本地运行的.net WebServer进行SOAP调用，但是我想我缺少了一些东西。 Android代码对我来说似乎很好。 也许SOAP请求是错误的...

这是网络服务器为我尝试调用的方法提供的：

POST /WebAvanza/WebAvanzaInterface.asmx HTTP/1.1
Host: localhost
Content-Type: application/soap+xml; charset=utf-8
Content-Length: length

<?xml version="1.0" encoding="utf-8"?>
<soap12:Envelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:soap12="http://www.w3.org/2003/05/soap-envelope">
  <soap12:Body>
    <InitTransazione xmlns="http://tempuri.org/">
      <ip>string</ip>
      <codice>string</codice>
    </InitTransazione>
  </soap12:Body>
</soap12:Envelope>

这是我到目前为止写的：

private String InitTransaction(String command){
        String NAMESPACE = "http://tempuri.org/";
        String METHOD_NAME = "InitTransazione";
        SoapObject request = new SoapObject(NAMESPACE, METHOD_NAME);
        request.addProperty("ip", ipAddress);
        request.addProperty("codice", command);

        SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(SoapEnvelope.VER11);
        envelope.dotNet = true;
        envelope.setOutputSoapObject(request);

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

        String SOAP_ACTION = NAMESPACE + METHOD_NAME;

        Object result = null;
        try {
            httpTransport.call(SOAP_ACTION, envelope);
            result = envelope.getResponse();
        }
        catch(Exception e)
        {
            e.printStackTrace();
        }

        return String.valueOf(result);
    }

URL是http://192.168.168.24/WebAvanza/WebAvanzaInterface.asmx ，该地址是指运行服务器的计算机。

我只在执行httpTransport.call之后得到异常。

这是StackTrace（如果需要的话）

Answer 1

我发现问题出在服务器上，代码也没问题……该死，我在这个.__之后花费了将近5个小时。

Answer 2

检查代码我认为主要问题是因为您没有在异步线程中执行Okhttpclient。

我认为，如果使用Okhttpclient的enqueue方法运行代码，则应该解决该问题。

client.newCall(request).enqueue(new Callback() {
      @Override public void onFailure(Call call, IOException e) {
        //Exception here
        }

      @Override public void onResponse(Call call, Response response) throws IOException {
        try (ResponseBody responseBody = response.body()) {
           /*
           * Handle your response here :
           * Do whatever you want if the response.isSuccesful or not
           */ 
        }
    });

希望对您有帮助。
