REST和SOAP webservice在android中

优点：

• Langauge,platform,and transport agnostic
• Designed to handle distributed computing environments
• Is the prevailing standard for web services,and hence has better support from other standards (WSDL,WS-*) and tooling from vendors
• Built-in error handling (faults)
• Extensibility

缺点：

• Conceptually more difficult,more “heavy-weight” than REST
• More verbose
• Harder to develop,requires tools

休息

优点：

• Language and platform agnostic
• Much simpler to develop than SOAP
• Small learning curve,less reliance on tools
• Concise,no need for additional messaging layer
• Closer in design and philosophy to the Web

缺点：

• Assumes a point-to-point communication model–not usable for distributed computing environment where message may go through one or
  more intermediaries
• Lack of standards support for security,policy,reliable messaging,etc.,so services that have more sophisticated requirements are harder
  to develop (“roll your own”)
• Tied to the HTTP transport model

REST的示例

使用apache http jar

public void callRestWebService(){  
          System.out.println(".....REST..........");
             HttpClient httpclient = new DefaultHttpClient();  
             HttpGet request = new HttpGet(wsdlURL);  
             request.addHeader("company name","abc");  

             request.addHeader("getAccessNumbers","http://service.xyz.com/");
             ResponseHandler<String> handler = new BasicResponseHandler();  
             try {  
                 result = httpclient.execute(request,handler); 
                 System.out.println("..result..."+result);
             } catch (ClientProtocolException e) {  
                 e.printStackTrace();  
             } catch (IOException e) {  
                 e.printStackTrace();  
             }  
             httpclient.getConnectionManager().shutdown();  

         } // end callWebService()  
     }

SOAP示例

您可以自己使用kso??ap或创建soap xml并发送到url

private boolean callSOAPWebService() {
        OutputStream out = null;
        int respCode = -1;
        boolean isSuccess = false;
        URL url = null;
        HttpsURLConnection httpURLConnection = null;

        try {

            url = new URL(wsdlURL);


            httpURLConnection = (HttpsURLConnection) url.openConnection();

            do {
                // httpURLConnection.setHostnameVerifier(DO_NOT_VERIFY);
                httpURLConnection.setRequestMethod("POST");
                httpURLConnection
                        .setRequestProperty("Connection","keep-alive");
                httpURLConnection
                        .setRequestProperty("Content-Type","text/xml");
                httpURLConnection.setRequestProperty("SendChunked","True");
                httpURLConnection.setRequestProperty("UseCookieContainer","True");
                HttpURLConnection.setFollowRedirects(false);
                httpURLConnection.setDoOutput(true);
                httpURLConnection.setDoInput(true);
                httpURLConnection.setUseCaches(true);
                httpURLConnection.setRequestProperty("Content-length",getReqData().length + "");
                httpURLConnection.setReadTimeout(10 * 1000);
                // httpURLConnection.setConnectTimeout(10 * 1000);
                httpURLConnection.connect();

                out = httpURLConnection.getOutputStream();

                if (out != null) {
                    out.write(getReqData());
                    out.flush();
                }

                if (httpURLConnection != null) {
                    respCode = httpURLConnection.getResponseCode();
                    Log.e("respCode",":" + respCode);

                }
            } while (respCode == -1);

            // If it works fine
            if (respCode == 200) {
                try {
                    InputStream responce = httpURLConnection.getInputStream();
                    String str = convertStreamToString(responce);
                    System.out.println(".....data....." + new String(str));

                    // String str
                    // =Environment.getExternalStorageDirectory().getAbsolutePath()+"/sunilwebservice.txt";
