账号和密码不能为空

Error message

账号和密码不能为空

What it means

doLogin validates inputs before attempting authentication and returns this error when username or password is empty after trimming whitespace. It is a synchronous pre-condition check, so no network call is made.

Solutions

1. Provide non-empty username and password in the user configuration before calling doLogin
2. Validate credentials at startup/config-load time and fail fast with a clear message
3. Trim inputs on the caller side and check for emptiness before invoking login

Example fix

// before
_, _, err := p.doLogin(cfg.Username, cfg.Password, true)
// after
if strings.TrimSpace(cfg.Username) == "" || strings.TrimSpace(cfg.Password) == "" {
    return errors.New("panlian 账号或密码未配置")
}
_, _, err := p.doLogin(cfg.Username, cfg.Password, true)

if strings.TrimSpace(cfg.PanlianUser) == "" || strings.TrimSpace(cfg.PanlianPass) == "" {
    return errors.New("panlian 凭据未配置")
}

When it happens

Trigger: Calling p.doLogin("", "", ...) or with a whitespace-only username/password, e.g. when user config fields are blank or only contain spaces.

Common situations: Missing PANLIAN username/password in config file or env; credentials loaded from an empty database record; TrimSpace turning " " into "".
