Add Support to Resolve MiyousheGeetestError

[seriaati]

Summary

Miyoushe API requests will fail when any request is being sent from an unrecognized device, in a previous commit I implemented a check to raise MiyousheGeetestError if that is the case, but there are currently no ways of resolving those errors with the library.

Here are 3 ways (that I know) to resolve the error.

1. Pass in Device Information (Easiest to Implement)

This requires the user to have a device that is already "trusted", typically a phone that has the Miyoushe app installed and has been logged in with the Miyoushe account for a long period of time. When requesting, pass in the information of that device through the device_fp and device_id headers, and theoretically Miyoushe will think this request is secure and will not raise the error. A possible implementation is to allow users to pass in custom headers during genshin.Client initialization, and the client will use them in all requests.

2. Solve the Geetest and Re-Request (WIP)

This is what I am currently working on, though not quite successful.
The code snippet below is what I plan to implement this solution:

import genshin

client = genshin.Client(...) # Fill in cookies, region, game and any other information
try:
      result = await client.get_genshin_notes()
except genshin.MiyousheGeetestError:
      mmt = await client.create_mmt()
      mmt_result = await server.solve_geetest(mmt, api_server="api.geetest.com", proxy_geetest=True)
      await client.verify_mmt(mmt_result)
      # Re-request
      result = await client.get_genshin_notes(mmt_result=mmt_result)

However, I encountered an unknown error with retcode 10306 and no error message in verify_mmt. So, I'm stuck.

3. Make the Device Become a Trusted Device

There is little information on this yet, but while looking at gsuid_core's code when I'm trying to resolve the error above, I noticed that it seems to be possible to generate random device information and make them become trusted through API requests, I will look more into this. Also, I'm thinking about adding methods to the auth client that generate random device information, but I need to figure out what device_fp, device_id, and x-rpc-device_id are.

Side Notes

We don't necessarily need to implement all 3 solutions, in fact any one of them being implemented should be enough for the user.

Task List

• Pass in Device Information
• Solve the Geetest and Re-Request
• Make the Device Become a Trusted Device
