Original GitHub issue: https://github.com/ProxymanApp/Proxyman/issues/931

Originally assigned to: @NghiaTranUIT on GitHub.

Proxyman version? (Ex. Proxyman 1.4.3)

2.29.0 (22900)

macOS Version? (Ex. mac 10.14)

11.4

Steps to reproduce

Open Charles Proxy on iOS
Capture traffic
Export session as a .chlsj JSON-formatted Charles file
Open ProxyMan
Select File > Open… and select the chlsj file from the file browser
The chlsj file is unable to be selected.

Expected behavior

Proxyman currently supports reading in chls files which are binary-formatted Charles files. It can also convert them to HAR files for sharing with other users. The chlsj JSON-formatted files should be able to be read into Proxyman in addition to the binary formatted files.

In the course of work someone will share a chlsj file that was captured on an iOS device. To use Proxyman with this file I have to open the file in Charles and export it in chls format. Unfortunately this causes a crash in Proxyman (see the chls exported from a chlsj and the crash attatched in the zip file).

Screenshots (optional)

Hey @danimal please check out this Beta build: https://proxyman.s3.us-east-2.amazonaws.com/beta/Proxyman_2.29.0_Import_chlsj_files.dmg

What's new

Drag & drop the chlsj file and directly open it with Proxyman app
Fix crashed when opening the HAR file, which is exported from the chlsj file

Notes

This version will require you to update a new Helper Tool (v1.3) https://github.com/ProxymanApp/Proxyman/issues/923

Please let me know if it works for you @danimal 😄

@NghiaTranUIT Thanks for the really quick reply! Both the chlsj and the exported chls from a chlsj work great! I was even able to open a 4.5GB chlsj file we gathered from on-device testing. Thank you again for the quick work.

I also really appreciate the Helper Tool upgrade message on app launch. Great work.

This alone is a reason for me to get the license and support further development. Prefer charles on iOS (to be fair, its been a while since I tried proxyman iOS, will give it another shot), but proxyman mac app is just SO much better than charles as a viewer and recorder, keep it up guys!

Oh yes, now I remember, I wasn't able to enable ssl for ALL domains. When I need https sniffing, I usually want all domains intercepted, enabling on domain level after the request was already made is a bit annoying (especially since I don't know all the domains that I'll need beforehand). I think there was some wildcard option, but it didn't work for me.
