Method

BBjVector

getHeaders(string name)

Parameters

Variable

Description

name

the name of the header

Return Value

a BBjVector containing the header value(s)

Remarks

in most cases a header has only one value and using BBjspWebRequest::getHeader(String) would be the better option.
Use this method if you need to check for multiple values of the header.

Example

This example demonstrates how this works in a BBJSP web-page

<!DOCTYPE html/>
<%@ taglib uri='/WEB-CFG/tld/core.tld' prefix='c' %>
<html>
  <body>
    <ul>
      <c:iterate data="<%= #getRequest().getHeaderNames() %>" id="headerName">
      <li><b>HEADER: ${headerName}</b>
      <ul>
      <%
        REM = Get the "headerName" from the page context
        hName$ = #PageContext!.getAttribute("headerName")
      %>
      <c:iterate data='<%= #getRequest().getHeaders(hName$) %>' id='headerValue' >
        <li>${headerValue}</li>
      </c:iterate>
      </ul>
      </c:iterate>
    </ul>
  </body>
</html>

This example demonstrates how this works in a BBJSP servlet

class public MyServlet

  field private BBjspWebRequest request!
  field private BBjspWebResponse response!
  field private BBjspWebSession session!
  
  method public void service(BBjspServletContext context!)
       
    #request! = context!.getRequest()
    #response! = context!.getResponse()

    #response!.setContentType("text/html")
    s! = #response!.getOutputStream()
    
    #session! = #request!.getSession()
    
    s!.write("<html><body><h1>Hello from BBJSP</h1>")
    vectHeaders! = #request!.getHeaders("Header")
    sz = vectHeaders!.size()
    if sz then
      s!.write("<ul>")
      for i = 0 to sz - 1
        s!.write("<li>" + vectHeaders!.get(i))
      next i
      s!.write("</ul>")
    endif
    s!.write("</body></html>")
  methodend
classend
