Usage

From source file:org.eclipse.californium.proxy.HttpTranslator.java

/**
 * Gets the http request starting from a CoAP request. The method creates
 * the HTTP request through its request line. The request line is built with
 * the uri coming from the string representing the CoAP method and the uri
 * obtained from the proxy-uri option. If a payload is provided, the HTTP
 * request encloses an HTTP entity and consequently the content-type is set.
 * Finally, the CoAP options are mapped to the HTTP headers.
 * /*from   w w w  .  j a va2  s  .c o  m*/
 * @param coapRequest
 *            the coap request

 * @return the http request * @throws TranslationException the translation
