<div dir="ltr">I'm working on an nginx module which will handle POST requests. I've never written an nginx module before, but I have worked on apache modules. My goal is to have it do unbuffered reads and process the data being posted as it arrives. Initially, I'm doing just a simple blocking read of the POST body. I've simplified things down almost to the "hello world" level.<div><br></div><div>When I do a POST, my module gets called, but I get a 404 not found, I am not sure why. I do see the file I post being uploaded and stored in a file in the nginx temporary file area. I do not see an entry in the access log showing the POST, again I am not sure why. How can I fix these things?</div><div><br></div><div>Source to my module:</div><div><a href="https://github.com/benmesander/ngx-dashll-module/tree/main">https://github.com/benmesander/ngx-dashll-module/tree/main</a></div><div><br></div><div>Results of sending a POST request:</div><div><br></div><div>
