java url 编码
POST过去的数据是不用URL编码的。
你先request.getParameter("xm")获取下，看是否正确，如果是问号的话就转换下
new String(request.getParameter("xm").getBytes("iso8859_1"),"gbk");
你这个是在Java里面获取的？request是JSP里面的一个对象，在Java里就需要传入一个HttpServletRequest实例了。
java怎么提取下面字符串中的地址
这个可以用正则表达式，给你写了个简单的你代码，我测试过了，希望对你有帮助~！
import java.util.regex.Matcher;
import java.util.regex.Pattern;
public class ExtractAddress {
public static void main(String[] args) {
String s = "var _url = \"\";";
Pattern pattern = Pattern.compile("\"(.*)\"");
Matcher m = pattern.matcher(s);
if(m.find())
System.out.println(m.group(1));
else
System.out.println("没找到相关地址");
}
}
java 用 HttpClients 请求 url 返回状态码是 503 怎么处理
// 用getResponseCode可以获取a href=";tn=44039180_cprfenlei=mv6quAkxTZn0IZRqIHckPjm4nH00T1d9rHnkmWD3nWbdnANBnj-W0ZwV5Hcvrjm3rH6sPfKWUMw85HfYnjn4nH6sgvPsT6KdThsqpZwYTjCEQLGCpyw9Uz4Bmy-bIi4WUvYETgN-TLwGUv3EnHRYnHndP1fdPH6Ynj0snWfzPs" target="_blank" class="baidu-highlight"URL/a返回状态码
String sa href=";tn=44039180_cprfenlei=mv6quAkxTZn0IZRqIHckPjm4nH00T1d9rHnkmWD3nWbdnANBnj-W0ZwV5Hcvrjm3rH6sPfKWUMw85HfYnjn4nH6sgvPsT6KdThsqpZwYTjCEQLGCpyw9Uz4Bmy-bIi4WUvYETgN-TLwGUv3EnHRYnHndP1fdPH6Ynj0snWfzPs" target="_blank" class="baidu-highlight"url/a = "";
try {
sa href=";tn=44039180_cprfenlei=mv6quAkxTZn0IZRqIHckPjm4nH00T1d9rHnkmWD3nWbdnANBnj-W0ZwV5Hcvrjm3rH6sPfKWUMw85HfYnjn4nH6sgvPsT6KdThsqpZwYTjCEQLGCpyw9Uz4Bmy-bIi4WUvYETgN-TLwGUv3EnHRYnHndP1fdPH6Ynj0snWfzPs" target="_blank" class="baidu-highlight"url/a="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());
}
