Method Details

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=677gi6ouf29bninvalid input: '&b'=2invalid input: '&f'=s
    Cache-Control: no-cache

become

{...
    Date: "Sun, 26 May 2002 18:06:04 GMT",
    Cookie: "Q=q2=PPEAsg--; B=677gi6ouf29bninvalid input: '&b'=2invalid input: '&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.
