How it is possible to read a response body while using Zuul as a proxy in post filter?
I am trying to call the code like this:
@Component
public class PostFilter extends ZuulFilter {
private static final Logger log = LoggerFactory.getLogger(PostFilter.class);
@Override
public String filterType() {
return "post";
}
@Override
public int filterOrder() {
return 2000;
}
@Override
public boolean shouldFilter() {
return true;
}
@Override
public Object run() {
RequestContext ctx = RequestContext.getCurrentContext();
ctx.getResponseBody(); // null
// cant't do this, cause input stream is used later in other filters and I got InputStream Closed exception
// GZIPInputStream gzipInputStream = new GZIPInputStream(stream);
return null;
}
}
I've managed to overcome this. The solution consists of 4 steps:
ctx.getResponseDataStream() into a ByteArrayOutputStreamcontext.setResponseBody(inputStream)
