java – Jsoup在Google Maps API上返回错误400

我在Google Geocoding APIs上玩了一点,我认为它们是我需要的：我所需要做的就是连接到DBMS,检索item_id和地址,生成地理编码API的有效URL并处理它将获得的JSON数据.

我不明白为什么,但我生成的URL在我的浏览器中运行(Chrome 23和最新的Safari,OS X),但在Jsoup中不起作用.我查看了Chrome中页面的来源,看起来它是完全有效的HTML.那么什么是Jsoup做错了？

代码片段(可运行,将为您提供相同的异常)：

import java.io.IOException;
import org.jsoup.Jsoup;
import org.jsoup.nodes.Document;

public class RandomClass {
     public static void main(String args[]) {
     Document doc = null;
     try {
        String url = "http://maps.googleapis.com/maps/api/geocode/json?address=0+164+W+75th+St,+New%20York,+NY+10024&sensor=false";

        String ua = "Mozilla/5.0 (Macintosh; Intel Mac OS X 10_7_5) AppleWebKit/537.17 (KHTML,like Gecko) Chrome/24.0.1312.56 Safari/537.17";
        doc = Jsoup.connect(url).timeout(60 * 1000).userAgent(ua).get();
    } catch (IOException e) {
        e.printStackTrace();
    }
}

}
