Method Detail

### toJSONObject

    public static JSONObject toJSONObject(String string)
                                   throws JSONException

  Convert an HTTP header string into a JSONObject. It can be a request header or a response header. A request header will contain

       {
          Method: "POST" (for example),
          "Request-URI": "/" (for example),
          "HTTP-Version": "HTTP/1.1" (for example)
       }

  A response header will contain

       {
          "HTTP-Version": "HTTP/1.1" (for example),
          "Status-Code": "200" (for example),
          "Reason-Phrase": "OK" (for example)
       }

  In addition, the other parameters in the header will be captured, using the HTTP field names as JSON names, so that

          Date: Sun, 26 May 2002 18:06:04 GMT
          Cookie: Q=q2=PPEAsg--; B=677gi6ouf29bn&b=2&f=s
          Cache-Control: no-cache

  become

       {...
          Date: "Sun, 26 May 2002 18:06:04 GMT",
          Cookie: "Q=q2=PPEAsg--; B=677gi6ouf29bn&b=2&f=s",
          "Cache-Control": "no-cache",
       ...}

  It does no further checking or conversion. It does not parse dates. It does not do '%' transforms on URLs.

  Parameters:
    `string` - An HTTP header string.
  Returns:
    A JSONObject containing the elements and attributes of the XML string.
  Throws:
    `JSONException`

### toString

    public static String toString(JSONObject o)
                           throws JSONException

  Convert a JSONObject into an HTTP header. A request header must contain

       {
          Method: "POST" (for example),
          "Request-URI": "/" (for example),
          "HTTP-Version": "HTTP/1.1" (for example)
       }

  A response header must contain

       {
          "HTTP-Version": "HTTP/1.1" (for example),
          "Status-Code": "200" (for example),
          "Reason-Phrase": "OK" (for example)
       }

  Any other members of the JSONObject will be output as HTTP fields. The result will end with two CRLF pairs.

  Parameters:
    `o` - A JSONObject
  Returns:
    An HTTP header string.
  Throws:
    `JSONException` - if the object does not contain enough information.
