Mam bardzo prosty kod, który nie działa.HttpURLConnection Wywołanie GET z niepoprawnymi parametrami
Klasa HttoCon:
package test;
import java.io.BufferedReader;
import java.io.InputStream;
import java.io.InputStreamReader;
import java.net.HttpURLConnection;
import java.net.URL;
import java.net.URLConnection;
import java.net.URLEncoder;
public class HttpCon {
public static void main(String[] args) {
try {
sendGet();
} catch (Exception e) {
e.printStackTrace();
}
}
// HTTP GET request
private static void sendGet() throws Exception {
String url = "http://myweb.com/public/resource/data/stream";
URL obj = new URL(url);
HttpURLConnection con = (HttpURLConnection) obj.openConnection();
// optional default is GET
con.setRequestMethod("GET");
//add request header
con.setRequestProperty("begin", "1430295300000");
con.setRequestProperty("end", "1430297279988");
con.setRequestProperty("id", "140621");
con.setRequestProperty("time", "FIFTEEN_MINUTE");
int responseCode = con.getResponseCode();
System.out.println("\nSending 'GET' request to URL : " + url);
System.out.println("Response Code : " + responseCode);
BufferedReader in = new BufferedReader(
new InputStreamReader(con.getInputStream()));
String inputLine;
StringBuffer response = new StringBuffer();
while ((inputLine = in.readLine()) != null) {
response.append(inputLine);
}
in.close();
//print result
System.out.println(response.toString());
}
}
Błąd Ślad:
{"fault":{"exceptionType":"MissingServletRequestParameterException","host":"12.205.101.123","cause":"Required Long parameter 'id' is not present","status":"400","query":"/public/resource/data/stream","stackTrace":"org.springframework.web.bind.MissingServletRequestParameterException: Required Long parameter 'id' is not present\n\tat org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter$ServletHandlerMethodInvoker.raiseMissingParameterException(AnnotationMethodHandlerAdapter.java:774)\n\tat org.springframework.web.bind.annotation.support.HandlerMethodInvoker.resolveRequestParam(HandlerMethodInvoker.java:509)\n\tat
UWAGA:
Gdybym uderzył URL bezpośrednio w przeglądarce działa dobrze.
UPDATE:
Korzystanie curl:
curl -X GET http://myweb.com/public/resource/data/stream?begin=1430295300000&end=1430297279988&id=140621&time=FIFTEEN_MINUTE
Przede curl nie działa, a wyjątkiem jest ten sam -
curl -X GET 'http://myweb.com/public/resource/data/stream?begin=1430295300000&end=1430297279988&id=140621&time=FIFTEEN_MINUTE'
Ten curl działa poprawnie .
spróbuj con.setRequestProperty ("id", "140621L"); – Pratik
link nie działa – Pratik
@Pratik - zmieniłem link tylko dla celów demo. –
