在Android的REST和SOAP Web服务 [英] REST and SOAP webservice in android
本文介绍了在Android的REST和SOAP Web服务的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我发现教程使用KSOAP API使用SOAP Web服务。任何人都可以向我提供在获取REST Web服务和SOAP Web服务在Android的示例程序（教程）。我用Google搜索很多，但并没有发现这种类型的教程。
I found tutorial to use kSOAP api to use SOAP webservice. Can anyone provide me sample programs (tutorial) on getting REST webservice and SOAP webservice in android. I have googled lot but didn't find such type of tutorial.
推荐答案
SOAP
优点：
- 语言特点，平台和传输不可知
- 设计来处理分布式计算环境
- 是Web服务的prevailing标准，因此从其他标准更好的支持（WSDL，WS- *）和来自供应商的工具
- 内置错误处理（错误）
- 扩展
- 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：
- 在概念上更困难，更重量级比REST
- 更多详细
- 在艰苦开发，需要的工具
- Conceptually more difficult, more "heavy-weight" than REST
- More verbose
- Harder to develop, requires tools
REST
优点：
- 语言和平台无关
- 更易于开发比SOAP
- 小的学习曲线，减少对工具的依赖
- 在简洁，无需额外的消息层
- 建立更紧密的设计和理念，以网络
- 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：
- 假定一个点对点通信模型 - 不能用于分布式计算环境中，消息可以经过一个或 多家中介
- 缺乏对安全，策略，可靠的消息传递等标准的支持，让有更复杂的需求的服务更难 开发（滚你自己）
- 绑HTTP传输模式
- 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
使用的Apache HTTP罐
Example of REST
Use 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()
}
的SOAP的实施例
您可以使用KSOAP或自己创建SOAP XML和发送到网址
Example of SOAP
You can use either ksoap or create soap xml by yourself and send to 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\"?>"
+ "<soap:Envelope "
+ "xmlns:soap=\"http://schemas.xmlsoap.org/soap/envelope/\""
+ " xmlns:xsi=\"http://www.w3.org/2001/XMLSchema-instance\""
+ " xmlns:xsd=\"http://www.w3.org/2001/XMLSchema\"" + ">";
return soapHeader;
}
public static byte[] getReqData() {
StringBuilder requestData = new StringBuilder();
requestData.append(createSoapHeader());
requestData
.append("<soap:Body>"
+ "<getAccessNumbers"
+ " xmlns=\"http://service.xyz.com.com/\""
+ "</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();
} finally {
try {
is.close();
} catch (IOException e) {
e.printStackTrace();
}
}
return sb.toString();
}
