代理服務器(Proxy Server)是一種重要的伺服器安全功能，它的工作主要在開放系統互聯(OSI)模型的會話層，從而起到防火牆的.作用。下面小編準備了關於Java如何設定代理IP訪問網站的文章，提供給大家參考!
1.原始碼
import eredInputStream;
import ;
import onnection;
public class TestProxyIp {
public static void main(String args){
//roperties()roperty("proxySet", "true"); //如果不設定，只要代理IP和代理埠正確,此項不設定也可以
roperties()roperty("yHost", "");
roperties()roperty("yPort", "8080");
tln(getHtml("")); //判斷代理是否設定成功
}
private static String getHtml(String address){
StringBuffer html = new StringBuffer();
String result = null;
try{
URL url = new URL(address);
URLConnection conn = Connection();
equestProperty("User-Agent","Mozilla/4.0 (compatible; MSIE 7.0; Windows NT 5.1; GTB5; CLR 2.0.50727; CIBA)");
BufferedInputStream in = new BufferedInputStream(nputStream());
try {
String inputLine;
byte buf = new byte;
int bytesRead = 0;
while (bytesRead >= 0) {
inputLine = new String(buf, 0, bytesRead, "ISO-8859-1");
nd(inputLine);
bytesRead = (buf);
inputLine = null;
}
buf = null;
} finally {
e();
conn = null;
url = null;
}
result = new String(ring()()ytes("ISO-8859-1"), "gb2312")werCase();
}catch(Exception e){
tStackTrace();
return null;
}
html = null;
return result;
}
}
