工作记录：从action中请求另一个系统的方法,发送http请求

调用端的写法：(本例是action中,请求信用网的数据)，其中的HttpUtil,详见HttpUtil。java
String url = "http://xxxxxxx/creditJk/creditJkAction!getCreditEntList.dhtml?flag=true&search="+strSearch;
String is_exist=HttpUtil.sendURL(url);

public String requestURL(String url)
{
try {
String sCurrentLine;
String sTotalString;
sCurrentLine = "";
sTotalString = "";
java.io.InputStream l_urlStream;
java.net.URL l_url = new java.net.URL(url);
java.net.HttpURLConnection l_connection = (java.net.HttpURLConnection) l_url.openConnection();
l_connection.connect();
l_urlStream = l_connection.getInputStream();
java.io.BufferedReader l_reader = new java.io.BufferedReader(
new java.io.InputStreamReader(l_urlStream));
while ((sCurrentLine = l_reader.readLine()) != null) {
sTotalString += sCurrentLine;
}
l_urlStream.close();
return sTotalString;
} catch (Exception e) {
e.printStackTrace();
//throw new RuntimeException("连接服务器错误！");
return "error";
}
