为什么Jsoup设置***IP后连接失败
不使用proxy时运行十分稳定，一旦在Connection对象中设置proxy后就报错：connect time out。请求各位大神指导一二
主方法：
public class ProxyIpUtilTest {
public static void main(String[] args) {
int code = ProxyIpUtil.checkProxy(new Proxy(Proxy.Type.HTTP, new InetSocketAddress("180.118.134.123", 9000)), "http://www.baidu.com");
System.out.println(code);
}
}ProxyIpUtil.checkProxy():
public static int checkProxy(Proxy proxy, String validSite){
try {
URL url = new URL(validSite!=null?validSite:XxlCrawlerConf.SITE_BAIDU);
HttpURLConnection httpURLConnection = (HttpURLConnection) url.openConnection(proxy);
httpURLConnection.setRequestProperty("User-Agent", XxlCrawlerConf.USER_AGENT_CHROME);
httpURLConnection.setConnectTimeout(XxlCrawlerConf.TIMEOUT_MILLIS_DEFAULT);
httpURLConnection.setReadTimeout(XxlCrawlerConf.TIMEOUT_MILLIS_DEFAULT);
httpURLConnection.connect();
int statusCode = httpURLConnection.getResponseCode();
/*InputStream inputStream = httpURLConnection.getInputStream();
String content = IOUtil.toString(inputStream, null);
if(content.indexOf("百度") == -1){
logger.info(content);
return -1;
}*/
return statusCode;
} catch (IOException e) {
logger.error(e.getMessage(), e);
return -2;
}
}
报错：
