[Apiman-user] API policy response data handler

Hello, I'm trying to parse the response using responseDataHandler() in the custom policy. In cases, if the response from API is of certain content, I would like the Apiman to consider as failure. But I don't find a way to throw policy failure from responseDataHandler(). And I cannot achieve this in doApply() as the ApiResponse object does not have "content" to parse. Also, what I found is write(chunk) in the AbstractStream is called after doApply, so I cannot set any attributes in it to fetch it in doApply() and trigger doFailure(). For example, in below call, how to throw as policy failure after parsing the contents ? Or how can I access response content even before write() method. *URLRewritingPolicy.java* @Override protected IReadWriteStream<ApiResponse> responseDataHandler(ApiResponse response, IPolicyContext context, URLRewritingConfig policyConfiguration) { if (policyConfiguration.isProcessResponseBody()) { return new URLRewritingStream(context.getComponent(IBufferFactoryComponent.class), response, policyConfiguration.getFromRegex(), policyConfiguration.getToReplacement()); } else { return null; } } *URLRewritingStream.java* /** * @see io.apiman.gateway.engine.io.AbstractStream#write(io.apiman.gateway.engine.io.IApimanBuffer) */ @Override public void write(IApimanBuffer chunk) { if (buffer == null) { buffer = bufferFactory.cloneBuffer(chunk); } else { buffer.append(chunk); } atEnd = false; processBuffer(); } Best regards Balu
