创建请求失败: %v

Error message

创建请求失败: %v

What it means

This error is thrown by Eranet.request when http.NewRequest fails to construct the outgoing HTTP request object for calls to create, modify, or getRecordList. Given the fullURL is already assembled from a constant baseURL, a signed queryString, and a method variable, failure almost always means an invalid HTTP method string or a malformed URL (e.g. unparsable characters in the query string). It wraps the underlying net/url parse error with %v.

Solutions

1. Trim and validate the API secret/key and all parameter values for whitespace or control characters before calling create/modify
2. Verify the method argument is exactly GET or POST (uppercase, no spaces)
3. Print/inspect the fullURL (it is baseURL+apiPath+"?"+queryString) to spot malformed characters
4. Check util.PercentEncode output for the offending parameter

Example fix

// before
req, err := http.NewRequest(method, fullURL, nil)
// after
method = strings.ToUpper(strings.TrimSpace(method))
fullURL = strings.TrimSpace(fullURL)
req, err := http.NewRequest(method, fullURL, nil)
if err != nil {
    return nil, fmt.Errorf("创建请求失败: %v", err)
}

method = strings.ToUpper(strings.TrimSpace(method))
if method != http.MethodGet && method != http.MethodPost {
    return fmt.Errorf("unsupported method: %q", method)
}
for k, v := range params {
    if strings.ContainsAny(v, " \t\r\n\x00") {
        return fmt.Errorf("parameter %q contains invalid characters", k)
    }
}

func isValidMethod(m string) bool {
    switch strings.ToUpper(strings.TrimSpace(m)) {
    case http.MethodGet, http.MethodPost:
        return true
    }
    return false
}

body, err := eranetClient.CreateRecord(params)
if err != nil {
    if strings.Contains(err.Error(), "创建请求失败") {
        // request construction failed: method/URL malformed — fix inputs, no retry
        return fmt.Errorf("eranet request malformed: %w", err)
    }
    return err
}

When it happens

Trigger: http.NewRequest returns an error when the method contains invalid characters or the fullURL fails url.Parse — e.g. a method other than a standard verb with bad characters, or a queryString containing raw spaces/control characters because signing/encoding (util.PercentEncode) produced an unexpected value.

Common situations: Misconfigured HTTP method passed down from create/modify; control characters or unencoded spaces in parameter values (API key/secret with trailing whitespace or newline) leaking into the query string; custom API paths containing characters illegal in URLs.
