Read binary-format return from HTTP request in cardano-http-bridge

I install cardano-http-bridge to connect with cardano’s node, when I send http to get detail a block, it’s return a binary format and I don’t know how to read it. anyone can help me(I use nodejs)

You don’t have any content type headers to help. Someone more expert will know, but I’d guess it is either/both encrypted and encoded, and the headers should be helpful (not always).
