Hi, Ranger team! I recently study on ranger, and call ranger rest api by
httpclient, but it failed!
The following is mycode:
public static void testGetRequest(String url) throws IllegalStateException,
IOException {
HttpClient client = new HttpClient();
StringBuilder sb = new StringBuilder();
InputStream ins = null;
GetMethod method = new GetMethod(url);
method.getParams().setParameter(HttpMethodParams.RETRY_HANDLER, new
DefaultHttpMethodRetryHandler(3, false));
int statusCode = client.executeMethod(method);
System.out.println("statusCode: " + statusCode);
if (statusCode == HttpStatus.SC_OK) {
ins = method.getResponseBodyAsStream();
byte[] b = new byte[1024];
int r_len = 0;
while ((r_len = ins.read(b)) > 0) {
sb.append(new String(b, 0, r_len, method.getResponseCharSet()));
}
}
method.releaseConnection();
if (ins != null) {
ins.close();
}
}
public static void main(String[] args) throws Exception {
String url = "http://10.133.47.146:6080/service/public/v2/api/policy/1";;
testGetRequest(url);
}
Run the above program, the statusCode is 401! Unauthorized !
Could I add any parameter when I call the rest api? How to resolve the
problem? I hope you can describe how to call ranger rest api on
https://cwiki.apache.org/confluence/display/RANGER/Index .
Thank you very much! Good Luck!
Seymour Xu.
