fish2018/pansou · error

站点地址不能为空

Error message

站点地址不能为空

What it means

normalizeBaseURL in the gying plugin rejects an empty site address. The user-provided base URL configuration, after trimming whitespace and trailing slashes, is an empty string, so no valid base URL can be constructed.

Solutions

Set the site address in the gying plugin configuration to a real host, e.g. https://example.com.
Strip quotes/whitespace when copying the URL into the config.
Verify the config file is the one actually being loaded (right profile/env).

Example fix

// before (config)
{ "site": "" }
// after (config)
{ "site": "https://gying.example.org" }

Defensive patterns

Strategy: validation

Validate before calling

site := strings.TrimSpace(cfg.Site)
if site == "" {
    return errors.New("gying site address must be configured")
}

Try / catch

if err := plugin.Configure(cfg); err != nil {
    if strings.Contains(err.Error(), "站点地址不能为空") {
        return fmt.Errorf("config error: set the gying 'site' field: %w", err)
    }
    return err
}

Prevention

Validate config at startup and fail fast with a clear message
Provide a default/example value in the config template
Trim whitespace when reading user-supplied config values
Add a UI/config check that the site field is non-empty before saving

When it happens

Trigger: normalizeBaseURL: raw is empty or only whitespace (and optionally '/' characters), so baseURL == "" after TrimSpace/TrimRight.

Common situations: Plugin configured with an empty site field in the config file or UI; env/config value never set; whitespace-only value pasted by mistake.
