这篇文章主要介绍了如何基于java或js获取URL返回状态码,文中通过示例代码介绍的非常详细，对大家的学习或者工作具有一定的参考学习价值,需要的朋友可以参考下
描述：使用java或者js访问某个网站，返回状态码
1.java实现
// 用getResponseCode可以获取URL返回状态码
String surl = "";
try {
surl="你的url";
URL url = new URL(surl);
URLConnection rulConnection = url.openConnection();
HttpURLConnection httpUrlConnection = (HttpURLConnection) rulConnection;
httpUrlConnection.setConnectTimeout(300000);
httpUrlConnection.setReadTimeout(300000);
httpUrlConnection.connect();
String code = new Integer(httpUrlConnection.getResponseCode()).toString();
String message = httpUrlConnection.getResponseMessage();
System.out.println("getResponseCode code ="+ code);
System.out.println("getResponseMessage message ="+ message);
if(!code.startsWith("2")){
throw new Exception("ResponseCode is not begin with 2,code="+code);
}
System.out.println(getCurDateTime()+"连接"+surl+"正常");
}catch(Exception ex){
System.out.println(ex.getMessage());
}
2.js实现（成功会返回200，如果页面找不到会返回404）
function GetHttpStatusCode($url){
$curl = curl_init();
curl_setopt($curl,CURLOPT_URL,$url);//获取内容url
curl_setopt($curl,CURLOPT_HEADER,1);//获取http头信息
curl_setopt($curl,CURLOPT_NOBODY,1);//不返回html的body信息
curl_setopt($curl,CURLOPT_RETURNTRANSFER,1);//返回数据流，不直接输出
curl_setopt($curl,CURLOPT_TIMEOUT,30); //超时时长，单位秒
curl_exec($curl);
$rtn= curl_getinfo($curl,CURLINFO_HTTP_CODE);
curl_close($curl);
return $rtn;
}
$url = "http://www.baidu.com"；
GetHttpStatusCode（$url）;
