You can use mitmproxy
to generate a HTTP Archive format (HAR) file for encrypted HTTPS traffic. Akita can then convert the HAR file into an API spec.
Convert HAR File to API Spec
All you need is a single command to convert a HAR file into an API spec:
akita apispec --traces path/to/trace.har \
--out akita://myService:spec:mySpec
Learn more about the apispec
command here.
Generate HAR File using mitmdump
In this example, we're going to generate a HAR file for encrypted traffic using mitmdump, which is part of the mitmproxy ecosystem.
Step 1: Download the official HAR conversion script.
You can find the python script for converting mitmdump
to HAR file on GitHub (link).
wget https://raw.githubusercontent.com/mitmproxy/mitmproxy/master/examples/contrib/har_dump.py
Step 2: Start mitmdump to dump HAR file
mitmdump -s ./har_dump.py --set hardump=./dump.har
Step 3: Direct some traffic through the proxy.
You can configure your browser or system to use the local proxy started by mitmdump
. Here we demonstrate an example using curl
.
curl -D - -k --proxy localhost:8080 https://www.google.com
Generate HAR file using Charles Proxy
In this example, we're going to generate a HAR file for encrypted traffic using Charles Proxy.
Step 1: Enable SSL Proxy for All Hosts
Under Proxy > SSL Proxying Settings
:
- Make sure "Enable SSL Proxying" is checked
- Add a new Host
*
to enable SSL proxying for all requests.


Step 2: Direct some traffic through the proxy.
You can configure your browser or system to use the local proxy started by mitmdump
. Here we demonstrate an example using curl
.
curl -D - -k --proxy localhost:8888 https://www.google.com
Step 3: Export a HAR file
Under File > Export Session
, select HTTP Archive (.har)
as the Filter.
