Method Detail

process

public java.lang.Object process(java.lang.String method,
                       java.lang.String requestUri,
                       Record inputRecord,
                       HttpExchange exchange)
                         throws java.lang.Exception

process input record and return result object. Override this method in your handler if you need access to HttpExchange object, e.g. to read http header fields

Overrides:

process in class JsonRequestHandler

Parameters:

method - HTTP method

requestUri - request URI.

inputRecord - input record parsed either from request body, if it has content, or from request URI parameters.

exchange - http exchange object, contains e.g. the http header fields

Returns:

result object, may be null. If this is not a Record, you have to provide a JsonRequestHandler.writeResultObject(OutputStream, Object) method, too.

Throws:

java.lang.Exception - any failure during processing.

getSuccessStatus

protected int getSuccessStatus(java.lang.String method,
                   java.lang.String requestUri)

result status for POST requests should be CREATED.

Overrides:

getSuccessStatus in class JsonRequestHandler

Parameters:

method - HTTP method

requestUri - request URI

Returns:

the status code to return for successful requests using the method and request URI. By default it is "OK" (200).

isValidMethod

protected boolean isValidMethod(java.lang.String method,
                    java.lang.String requestUri)

Set GET instead of POST as basic method. GET and POST are currently the only valid methods.

Overrides:

isValidMethod in class AJobManagerHandler

Parameters:

method - HTTP method

requestUri - request URI

Returns:

true if the method can be used for the URI, else false.
