Hello

I am opening Https url using HttpsConnection class & Connector.Open() but response code return by code is 302 not 200.

Can any body tells why response code is 320 not 200.

you can check whether there is some thing wrong wd my code. My code is as follow:-


StringBuffer sb = new StringBuffer();

HttpsConnection httpConn = null;
InputStream is = null;
OutputStream os = null;
int res=0;

try {


httpConn = (HttpsConnection) Connector.open(url);
httpConn.setRequestMethod(HttpsConnection.POST);

httpConn.setRequestProperty("User-Agent",
"Profile/MIDP-2.0 Confirguration/CLDC-1.0");
httpConn.setRequestProperty("Accept_Language", "en-US");
httpConn.setRequestProperty("Content-Type",
"application/x-www-form-urlencoded");


res=httpConn.getResponseCode();

is = httpConn.openDataInputStream();

int chr;
while ((chr = is.read()) != -1)
sb.append((char) chr);

} catch (IOException e) {
e.printStackTrace();
} finally {

try {
if (is != null)
is.close();
if (os != null)
os.close();
if (httpConn != null)
httpConn.close();

} catch (IOException e) {
e.printStackTrace();
}
}
return res+sb.toString();
}

HTTP 302 is a redirect.

You should get the redirect URL in the "Location" header in the response.

You then re-connect to this new location.

How can I get the redirect URL in the "Location" header.
Can you please explain
In my code where i hv to make this change?

[xmncxzvt]

Can you please explain in detail what you mean?

[Dougsg38p]

You need to get the "Location" property header from the HTTP response.

String location = httpConnection.getHeaderField("Location");

This gives you the redirected URL. You then load this URL to replace whatever URL you originally were going after, and try again.

You understand that this is strictly HTTP 1.1 stuff, and documented in about 1,000,000 places, right? Try "google" searching for HTTP 302 and you will find plenty of reference material.

Thanks Dougsg38p
I got your suggestion
This means that
String location =httpConnection.getHeaderField("Location"); gives redirected url.
Some sites provide their url which redirects to another url (actual url) or we
can say that some sites doesnt gave direct access to their url.So, we are
accessing those sites indirectly.when we enter url in browser it automatically access redirected url & opens page but in code when we create httpconnection & gave it in url, it doesnt automatically opens redirected url.

So, we get redirected url from getHeaderField() , create another httpconnection object & gave it redirected url like this:

HttpsConnection httpconn = null;
HttpsConnection hc = null;
InputStream is = null;


httpConn = (HttpsConnection) Connector.open(url);
httpConn.setRequestMethod(HttpsConnection.POST);

String location =httpConn.getHeaderField("Location");

hc = (HttpsConnection) Connector.open(location);
is = hc.openDataInputStream();

I havent implemented this change to my code yet. But I think now response
code must be 200 because i am creating another httpconnection object &
giving it redirected url.

Let me make this change to my code

I think you have the picture!

One more issue to be aware of: if you are on a *real* device and you applicaiton is connecting via BES or BIS-B, then the server-side handler will actually make the redirect for you, and you'll never know that it happened.

On Direct TCP or WAP connections (or any conneciton where you have sert ";deviceside=true", you will have to handle the redirect in your code.

Anyway, it's always a good idea to handle this, just in case.

Good luck with your program.
