我正在使用 HttpUrlConnection 来使用 REST 服务。当我执行 GET 时,就像我在下面展示的那样,我不想获取按字符返回的信息。我想以返回的格式获得结果。例如,在这里,我想获得一个布尔值,而不是类似System.out.print((char) ch);
. 我怎样才能收到它?
我知道我可以将 String 解析为 Boolean 类型,但是如果我收到另一种数据类型呢?
public class SensorGetDoorStatus {
public static void main(String[] args) throws Exception
{
HttpURLConnection urlConnection = null;
try {
String webPage = "http://localhost:8080/LULServices/webresources/services.sensors/doorstatus";
String name = "xxxx";
String password = "xxxx";
Authenticator myAuth = new Authenticator()
{
final String USERNAME = "xxxx";
final String PASSWORD = "xxxxx";
@Override
protected PasswordAuthentication getPasswordAuthentication()
{
return new PasswordAuthentication(USERNAME, PASSWORD.toCharArray());
}
};
Authenticator.setDefault(myAuth);
String authString = name + ":" + password;
byte[] authEncBytes = Base64.encodeBase64(authString.getBytes());
String authStringEnc = new String(authEncBytes);
URL urlToRequest = new URL(webPage);
urlConnection = (HttpURLConnection) urlToRequest.openConnection();
urlConnection.setRequestProperty("Authorization", "Basic " + authStringEnc);
System.out.println("Authorization : Basic " + authStringEnc);
urlConnection.setRequestMethod("GET");
urlConnection.setRequestProperty("Accept", "application/json");
urlConnection.setReadTimeout(15*1000);
urlConnection.connect();
InputStream inStrm = urlConnection.getInputStream();
int ch;
while (((ch = inStrm.read()) != -1))
System.out.print((char) ch);
inStrm.close();
} catch (MalformedURLException e) {
e.printStackTrace();
} catch (IOException e) {
System.out.println("Failure processing URL");
e.printStackTrace();
} catch (Exception e) {
e.printStackTrace();
}
finally {
if (urlConnection != null) {
urlConnection.disconnect();
}
}
}
}
