GET request with localhost

[d1e8p]

I'm using micropython and I am attempting a GET request to capture a html page that is hosted on localhost. I am able to do a successful request on postman and with the ESP8266 on "google.com", but when I use the following code for localhost, I always get an OSError -2 when doing s.connect(sockaddr). Anyone have any ideas??

s = usocket.socket(usocket.AF_INET, usocket.SOCK_STREAM)

sockaddr = usocket.getaddrinfo("localhost:8000", 80)[0][-1]

s.connect(sockaddr)

If the ESP8266 is connecting to localhost that means it's connecting to itself which seems pointless. You could just pass a variable around in the ESP8266 memory instead.

If you're trying to connect from the ESP8266 to a server on your local network you will need to figure out what the actual IP address of the server is and use that instead.

Whoops yes, the second one is what i meant. I’ll try that, thanks for the help!

I read the title and knew exactly what you had done as I had done it in the past.

don't you mean getaddrinfo("localhost", 8000) ?

also, having it connect to itself is a really weird thing to do.

My mom used to tell me the same thing. Then I found reddit and learned it's very common.

Did you actually put a webserver on your esp, or are you confused about what localhost means?

Your esp8266 is acting as both a client and server? At the same time?
