创建 dnsla 记录列表请求失败: %w

Error message

创建 dnsla 记录列表请求失败: %w

What it means

This error is thrown in getRecordList when http.NewRequest fails to construct the GET request that fetches the DNS record list from the dnsla API. The wrapping preserves the underlying cause (usually an invalid URL from bad parameters). It almost always indicates a malformed request URL rather than a network or credentials problem.

Solutions

1. Inspect the wrapped error's message to see which part of the URL http.NewRequest rejected
2. Print or log the value of recordList and params.Encode() before building the request to spot invalid characters
3. Verify the dnsla API endpoint constant has no whitespace, newline, or invalid characters
4. If the URL is fine, check for control characters in domain/param values passed in from the caller

Example fix

// before
url := recordList + "?" + params.Encode()
req, err := http.NewRequest("GET", url, nil)
if err != nil {
    return nil, fmt.Errorf("创建 dnsla 记录列表请求失败: %w", err)
}
// after
url := recordList + "?" + params.Encode()
if _, perr := url.Parse(url); perr != nil {
    return nil, fmt.Errorf("dnsla 记录列表 URL 无效 %q: %w", url, perr)
}
req, err := http.NewRequest("GET", url, nil)
if err != nil {
    return nil, fmt.Errorf("创建 dnsla 记录列表请求失败: %w", err)
}

u, err := url.Parse(recordList)
if err != nil || u.Scheme == "" || u.Host == "" {
    return fmt.Errorf("dnsla endpoint URL 无效: %q (%v)", recordList, err)
}

func isValidURL(s string) bool {
    u, err := url.Parse(s)
    return err == nil && u.Scheme != "" && u.Host != ""
}

if err != nil {
    return nil, fmt.Errorf("创建 dnsla 记录列表请求失败: %w", err)
}
// 调用方: 
records, err := getRecordList(...)
if err != nil {
    log.Printf("dnsla 记录列表请求构建失败: %v", err)
    return err
}

When it happens

Trigger: http.NewRequest returns an error, which for this call only happens when the constructed URL (recordList + '?' + params.Encode()) is unparseable — e.g. recordList endpoint constant is misconfigured or params contain characters that break URL parsing after Encode().

Common situations: A patched or forked endpoint URL containing spaces/invalid characters; custom build where the dnsla API base URL was overridden with an invalid value; unit-test stubs injecting a malformed endpoint.
