is simple words how to define port ?开发者_运维问答

You are attempting to perform a lookup of the host name https://foo.com and that's the problem; the lookup should have been against foo.com. I'm not sure as to how you've arrived at the code in question, but it would be worth some time to take a look at the HttpClient tutorial.

If I'm not wrong, the following code, should be sufficient:

HttpPost httpost = new HttpPost(url); //construct the complete URL i.e. action to post to
httpost.setEntity(entity);
response = httpclient.execute(httpost);

where url is to be constructed with the http/https schema, host name, port and the rest of the resource URI.
