我找到了使用kSOAP API使用SOAP Web服务的教程。有人能够为我提供在Android中获取REST Web服务和SOAP Web服务的示例程序(教程)吗?我已经搜索了很多,但没有找到这种类型的教程。

SOAP
优点:
- 语言、平台和传输方式不受限制
- 设计用于处理分布式计算环境
- 是Web服务的主流标准,因此得到其他标准(WSDL、WS-*)的更好支持以及来自供应商的工具
- 内置错误处理(故障)
- 可扩展性
缺点:
- 概念上更加困难、比REST更“重量级”
- 更冗长
- 开发更困难,需要使用工具
REST
优点:
- 语言和平台不受限制
- 比SOAP开发更简单
- 学习曲线小,对工具的依赖较少
- 简洁,不需要额外的消息层
- 在设计和哲学上更接近Web
缺点:
- 假定点对点通信模型--不能用于消息可能通过一个或多个中间层的分布式计算环境
- 缺乏安全、策略、可靠消息等方面的标准支持,因此具有更复杂要求的服务更难开发(需要自己开发)
- 与HTTP传输模型绑定
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()
}
您可以使用ksoap,也可以自己创建SOAP XML并将其发送到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";
// File f = new File(str);
//
// try{
// f.createNewFile();
// FileOutputStream fo = new FileOutputStream(f);
// fo.write(b);
// fo.close();
// }catch(Exception ex){
// ex.printStackTrace();
// }
} catch (Exception e1) {
e1.printStackTrace();
}
} else {
isSuccess = false;
}
} catch (IOException e) {
e.printStackTrace();
} finally {
if (out != null) {
out = null;
}
if (httpURLConnection != null) {
httpURLConnection.disconnect();
httpURLConnection = null;
}
}
return isSuccess;
}
public static String createSoapHeader() {
String soapHeader = null;
soapHeader = "<?xml version=\"1.0\" encoding=\"utf-8\"?>"

return soapHeader;
}
public static byte[] getReqData() {
StringBuilder requestData = new StringBuilder();
requestData.append(createSoapHeader());
requestData
.append("<soap:Body>"
+ "<getAccessNumbers"

+ "</getAccessNumbers> </soap:Body> </soap:Envelope>");
return requestData.toString().trim().getBytes();
}
private static String convertStreamToString(InputStream is)
throws UnsupportedEncodingException {
BufferedReader reader = new BufferedReader(new InputStreamReader(is,
"UTF-8"));
StringBuilder sb = new StringBuilder();
String line = null;
try {
while ((line = reader.readLine()) != null) {
sb.append(line + "\n");
}
} catch (IOException e) {
e.printStackTrace();

is.close();

你好,这里有一个实现SOAP的好例子。
我已经使用过这个例子,并且它对我完美地起作用了。你可以从这里下载ksoap2-android-assembly-2.4-jar-with-dependencies.jar库。
这是我的代码片段....
String NAMESPACE = "http://www.namespace.com/";
String METHOD_NAME = "login";
String SOAP_ACTION = "http://www.namespace.com/loginRequest";
String URL = "http://www.domainname.com:8080/AccessWEbService?wsdl";
SoapObject loginRequest = new SoapObject(NAMESPACE, METHOD_NAME);
SoapObject inLoginDto = new SoapObject(NAMESPACE, "LoginDetail");
inLoginDto.addAttribute("username", "");
inLoginDto.addProperty("username", etUserName.getText().toString());
inLoginDto.addProperty("password", etPassword.getText().toString());
loginRequest.addProperty("loginDetails", inLoginDto);
Log.e("Soap Request : ", "" + loginRequest);
SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(SoapEnvelope.VER11);
envelope.setOutputSoapObject(loginRequest);
AndroidHttpTransport androidHttpTransport = new AndroidHttpTransport(URL);
try {
androidHttpTransport.call(SOAP_ACTION, envelope);
SoapObject response = (SoapObject) envelope.getResponse();
Boolean loginStatus = Boolean.getBoolean(response.getProperty("success").toString());
}
catch (Exception e) {
Log.e("Exception ", "" + e);
}
如果可以帮助你,就试一试吧...
