以下のコードに問題があり、req.getHeader()
戻ってきましたNULL
// The code below returns the expected value
String header = req.getHeader("x-key");
String size = req.getHeader("x-size");
String contentType = req.getContentType();
logger.info("Content-Length: " + req.getContentLength());
logger.info("x-key : " + header);
logger.info("x-size : " + size);
// The value of req.getHeader below is returning NULL
for (Enumeration e = req.getHeaderNames(); e.hasMoreElements();) {
String headerName = (String) e.nextElement();
logger.info("Name = " + headerName + " " + "Value = " + req.getHeader(headerName ));
}
何が問題なのですか?
