尝试打开URL时,为什么会出现403错误

我目前正在使用http://imdbapi.org上的imdb api来获取有关电影的一些信息。 当我使用API​​并尝试在java中打开此URL时 ,它给出了403错误。 url应该以JSON格式返回数据。 这是我到目前为止的代码(Java 7):

import java.io.BufferedReader; import java.io.IOException; import java.io.InputStream; import java.io.InputStreamReader; import java.net.MalformedURLException; import java.net.URL; public class Test { public static void main(String[] args) { URL url =null; try { url = new URL("http://imdbapi.org/?q=batman"); } catch (MalformedURLException e) { // TODO Auto-generated catch block e.printStackTrace(); } InputStream is =null; try { is = url.openConnection().getInputStream(); } catch (IOException e) { // TODO Auto-generated catch block e.printStackTrace(); } BufferedReader reader = new BufferedReader( new InputStreamReader( is ) ); String line = null; try { while( ( line = reader.readLine() ) != null ) { System.out.println(line); } } catch (IOException e) { // TODO Auto-generated catch block e.printStackTrace(); } try { reader.close(); } catch (IOException e) { // TODO Auto-generated catch block e.printStackTrace(); } System.out.println(line); } } 

您应该设置User-Agent

 System.setProperty("http.agent", "Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/28.0.1500.29 Safari/537.36"); 

要么

 URLConnection connection = url.openConnection(); connection.setRequestProperty("User-Agent", "Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/28.0.1500.29 Safari/537.36"); is = connection.getInputStream();
