Proxying localhost http requests is not working.

[nextdimension]

intercepting localhost does not work.
i've removed the filter in the proxy settings.
i've tried using localhost.proxyman.io.
i've even set the value in the hosts file.
i'm on macos, latest version, fully updated.

either i'm doing something wrong proxyman is broken

You should edit the host file, so Proxyman can capture your localhost traffic, for example: http://localhost:3000

The reason is that no local traffic uses the proxy. It's how macOS works, and it's not a bug from Proxyman

I already wrote...

'i've even set the value in the hosts file.'

i followed your docs.

https://docs.proxyman.com/troubleshooting/couldnt-see-any-request-from-localhost-server#3-1-use-localhost-proxyman-io

Just tested: http://localhost.proxyman.io:4000 works fine. It capture localhost:4000

• Work with http://proxyman.debug:4000 too

can you share your host file? and your URL?

It's difficult to debug if you don't share anything except it didn't work

Host Database

localhost is used to configure the loopback interface

when the system is booting. Do not change this entry.

127.0.0.1 localhost
255.255.255.255 broadcasthost
::1 localhost
127.0.0.1 proxyman.debug
::1 proxyman.debug

I have a service running on localhost:8080
I am making a GET request using CURL to:

localhost:8080 and/or localhost.proxyman.io:8080
niether appear in proxyman GUI

ok, the problem is cURL doesn't use HTTP Proxy. It goes to the Internet.

Try

curl -v http://proxyman.debug:8080 --proxy localhost:9090

Or access it from Safari:

http://proxyman.debug:8080

if you don't want to use --proxy flag, just open Proxyman -> Setup Menu -> Automatic Setup -> New Terminal -> Run your cURL here. It auto proxies to Proxyman

ok, so the problem for me is, I want to capture all the http traffic. Not just the browser and some apps are curl wrappers, like postman.

I have a nodejs service that makes requests to lcoalhost:8080 and this is what I want to capture the traffiic for.

So proxyman can only capture browser traffic?

[NghiaTranUIT]

it's tricky to capture NodeJS requests, but Proxyman can work with 1 click by using the Automatic Setup that I show you in the previous chat.

Works with NodeJS: Axios, got, superagent, fetch, and node-fetch.

1. Open Proxyman -> Setup Menu -> Automatic Setup -> New Terminal
2. On this Terminal -> Start your NodeJS server
3. Proxyman will capture all request from your NodeJS server, for example axios

ok, I will try. thank you for the help.
Maybe easier to use wireshark :)
