[ZhiHu.begin]I nvalid Login Type Currently only supported qr

Error message

[ZhiHu.begin]I nvalid Login Type Currently only supported qrcode or phone or cookies ...

What it means

ValueError raised by ZhiHuLogin.begin when config.LOGIN_TYPE is not 'qrcode', 'phone', or 'cookies'. Note that zhihu accepts 'cookies' (plural) and that its phone login is a stub ('todo implement login by mobile'), so even the accepted 'phone' value currently does nothing. Pure config-validation error.

Solutions

Set LOGIN_TYPE to 'qrcode' or 'cookies' (plural) for zhihu.
Do not use 'phone' for zhihu yet - login_by_mobile is unimplemented.
Check the --lt CLI value for typos and case.

Example fix

# before
LOGIN_TYPE = "cookie"
# after
LOGIN_TYPE = "cookies"

Defensive patterns

Strategy: validation

Validate before calling

import config
assert config.LOGIN_TYPE in {"qrcode", "phone", "cookies"}, f"bad LOGIN_TYPE: {config.LOGIN_TYPE!r}"

Type guard

def is_valid_zhihu_login_type(value: str) -> bool:
    return isinstance(value, str) and value in {"qrcode", "phone", "cookies"}

Prevention

Zhihu accepts 'cookies' (plural); 'phone' login is an unimplemented stub - use qrcode or cookies.
Validate LOGIN_TYPE at startup with a per-platform allowlist.
Keep CLI --lt values in sync with the platform's accepted literals.

When it happens

Trigger: LOGIN_TYPE set to an unsupported literal, or set to 'cookie' (singular, weibo-style) which fails zhihu's check; also any typo/case mismatch.

Common situations: One shared LOGIN_TYPE reused across platforms while each platform checks different literals; user expects 'phone' to work and hits the unimplemented stub afterwards.
