I’m stuck on gzip compression stage 3. I’ve also tried sending the gzip compressed body as hex, base64. I’ve provided my current version of the code snippet below. Here are my logs: inner@afterlife:/mnt/d/projects/codecrafters-http-server-csharp$ codecrafters test Initiating test run... ⚡ This i…

Okay I managed to pass the test, my issue was that the gzip encoded data that I was passing wasn’t encoded properly in my response. The test is expecting gzip encoded data that it will open with gunzip and check that it returns the same string in the echo

I’m getting the same error in the test, I’ve also tried hex, base64 or binary but they all result in the same error. [http-compression-3] $ curl -v -X GET http://localhost:4221/echo/banana -H "Accept-Encoding: gzip" [http-compression-3] > GET /echo/banana HTTP/1.1 [http-compression-3] > Host: local…

thanks for the hint on gunzip. Tests passed

Hey! could you please post a snippet of your solution? I’ve already checked that my encoded response indeed returns the same input string after decompression - yet I am still getting the same error…

@noe-lc you’ll find code snippets from users who passed the stage in the “ Code Examples ” tab: [Screenshot 2024-05-14 at 22.26.36]

Thanks, I did check the examples - the logic looks is exactly same but just some implementation differences. Still do not know what in my code is wrong ,so I wanted to see how someone with the exact same issue worked around it :+1:

In my case, the Encoding.UTF8.GetString(compressedData) was impacting the result as this function call was converting the compatible gzip output to incompatible

For those stumbling upon this error while using TS and plain socket writes, you need to write the response in two parts: First write the startLine + headers: socket.write(startLineAndHeaders) Write the compressed data socket.write(compressedData) End the socket with socket.end() This is done so t…

Thanks! This worked for me. I was under the impression that I needed to send the hex representation of gzip zlib.gzipSync(string).toString('hex') and I would write the entire response with interpolated values. It seems I didn’t need the toString('hex') after all I just needed a 2nd write.
