use of org.eclipse.jetty.client.ProxyConfiguration.Proxy in project smarthome by eclipse.

the class HttpUtil method executeUrlAndGetReponse.

/**
 * Executes the given <code>url</code> with the given <code>httpMethod</code>
 *
 * @param httpMethod the HTTP method to use
 * @param url the url to execute
 * @param httpHeaders optional HTTP headers which has to be set on request
 * @param content the content to be send to the given <code>url</code> or <code>null</code> if no content should be
 *            send.
 * @param contentType the content type of the given <code>content</code>
 * @param timeout the socket timeout in milliseconds to wait for data
 * @param proxyHost the hostname of the proxy
 * @param proxyPort the port of the proxy
 * @param proxyUser the username to authenticate with the proxy
 * @param proxyPassword the password to authenticate with the proxy
 * @param nonProxyHosts the hosts that won't be routed through the proxy
 * @return the response as a ContentResponse object or <code>NULL</code> when the request went wrong
 * @throws IOException when the request execution failed, timed out or it was interrupted
