Method Detail

encode

public static void encode(StringBuilder urlstr,
                          String key)

URL encode a value string into an output buffer.

Parameters:

urlstr - the output buffer.

key - value which must be encoded to protected special characters.

response

public static int response(HttpURLConnection c)
                    throws IOException

Get the HTTP response code from the request.

Roughly the same as c.getResponseCode() but the ConnectException is translated to be more understandable.

Parameters:

c - connection the code should be obtained from.

Returns:

r HTTP status code, usually 200 to indicate success. See HttpURLConnection for other defined constants.

Throws:

IOException - communications error prevented obtaining the response code.

proxyFor

public static Proxy proxyFor(ProxySelector proxySelector,
                             URL u)
                      throws ConnectException

Determine the proxy server (if any) needed to obtain a URL.

Parameters:

proxySelector - proxy support for the caller.

u - location of the server caller wants to talk to.

Returns:

proxy to communicate with the supplied URL.

Throws:

ConnectException - the proxy could not be computed as the supplied URL could not be read. This failure should never occur.
