Apache HttpClient and custom ports

Question

I\'m using the Apache HttpClient 4 and it works fine. The only thing that doesn\'t work is custom ports. It seems like the root directory is fetched and the port is ignored.

Answer 1

One suggestion is to try using HttpPost(URI address) instead of the one with String parameter. You can explicitly set the port:

URI address = new URI("http", null, "my.domain.com", 50000, "/my_file", "id=10", "anchor") 
HttpPost post = new HttpPost(address);
HttpResponse response = httpClient.execute(post);

Can't guarantee this will work, but give it a try.

Another approach is to configure httpClient to use a custom SchemaPortResolver.

int port = 8888;
this.httpClient = HttpClients.custom()
        .setConnectionManager(connectionManager)
        .setConnectionManagerShared(true)
        .setDefaultCredentialsProvider(authenticator.authenticate(url,
                port, username, password))
        .setSchemePortResolver(new SchemePortResolver() {
            @Override
            public int resolve(HttpHost host) throws UnsupportedSchemeException {
                return port;
            }
        })
        .build();

This way, you avoid problems of using a String to construct a HttpPost and calling httpClient.execute(host, httpPost, handler, context), only finding your port is appended after the path, like: http://localhost/api:8080, which is wrong.

The problem was that the server does not understand HTTP 1.1 chunked transfers. I cached the data by using a ByteArrayEntity and all was ok.

So custom ports do work with the code mentioned above.
