제 서버에 soap webservice가 생성되었습니다. 그리고 "POST"메서드로 httpClient를 사용하여 내 비누 서비스에서 다른 서비스 (다른 서버에서)를 호출하려고합니다. "httpclient-4.2.2.jar"및 "httpcore-4.2.2.jar"를 사용했습니다.InvocationTargetException - httpClient를 사용하여 java Soap webservice에서 Rest service를 호출하십시오.
코드 스 니펫 :
public class User {
public static String addUser(String userEmail, String password) {
final String uri = "http://www.example.com/";
String requestParams = String.format("{\"userEmail\": \"%s\", \"password\": \"%s\"}", userEmail, password);
final HttpClient client = new DefaultHttpClient();
final HttpPost postMethod = new HttpPost(uri);
postMethod.setEntity(new StringEntity(requestParams, "utf-8"));
try {
final HttpResponse response = client.execute(postMethod);
final String responseData = EntityUtils.toString(response.getEntity(), "utf-8");
System.out.println(responseData);
} catch(final Exception e) {
e.printStackTrace();
}
return responseData;
}
}
나는 다음과 같은 코드를 사용하여 다른 클래스에서이 menthod 전화
.User.addUser(userEmail, password);
