I have a piece of code that hits my LinkSys router to get the IP address and
e-mail it if it has changed.
When using HTTPClient 2.0 RC1, it ran fine. When I upgraded to RC2, I get
the message
"WARNING: Response content length is not known"
I've isolated the two calls that result in the warning. They are:
int status = client.executeMethod( get );
and
get.getResponseBodyAsString();
Is there anything I can do to make this warning "go away"?
Here is the main procedure, to give you a better idea of what I'm doing:
String strHTML = new String();
String strIP = new String();
int statusCode = 0;
System.out.println("***** LSRouter start *****");
HttpClient client = new HttpClient();
client.getState().setCredentials("Linksys
BEFSR41/BEFSR11/BEFSRU31",
"192.168.1.1", new UsernamePasswordCredentials("user",
"pass"));
GetMethod get = new GetMethod("http://192.168.1.1/Status.htm";);
get.setDoAuthentication( true );
//client.setStrictMode(true); <--- no effect when enabled
//get.setStrictMode(true); <--- no effect when enabled
// execute the GET
int status = client.executeMethod( get );
// print the status and response
statusCode = get.getStatusCode();
System.out.println("Status = " + statusCode);
strHTML = StripHTML(get.getResponseBodyAsString());
strIP = locateIP(strHTML);
System.out.println("\n" + strIP);
And the wire output:
