解析代理URL失败

Error message

解析代理URL失败: %w

What it means

In dy4k's createProxyTransport, url.Parse failed on the configured HTTP (non-SOCKS5) proxy URL, so createProxyTransport aborts with this wrapped error. url.Parse is lenient but rejects control characters, invalid percent-escapes, and some malformed schemes. Nothing has connected yet; this is purely a URL-syntax failure in configuration.

Solutions

1. Log the exact proxyURL value and run url.Parse on it manually to see the parse error.
2. Normalize the config value: trim spaces/quotes and ensure a scheme prefix like http:// is present.
3. Pre-validate the proxy setting at startup and fail with a clear configuration message instead of at request time.
4. Use url.Parse with a scheme default, e.g. prepend "http://" when no scheme is present before parsing.

Example fix

// before
parsedURL, err := url.Parse(proxyURL)
if err != nil {
    return nil, fmt.Errorf("解析代理URL失败: %w", err)
}
// after
proxyURL = strings.TrimSpace(strings.Trim(proxyURL, "\"'"))
parsedURL, err := url.Parse(proxyURL)
if err != nil {
    return nil, fmt.Errorf("解析代理URL失败 %q: %w", proxyURL, err)
}

func validateHTTPProxy(proxyURL string) error {
    proxyURL = strings.TrimSpace(proxyURL)
    if !strings.Contains(proxyURL, "://") {
        proxyURL = "http://" + proxyURL
    }
    u, err := url.Parse(proxyURL)
    if err != nil { return err }
    if u.Host == "" { return fmt.Errorf("proxy missing host: %q", proxyURL) }
    return nil
}

func isParseableURL(s string) bool {
    _, err := url.Parse(strings.TrimSpace(s))
    return err == nil
}

When it happens

Trigger: The proxy string (from config/env) for the HTTP proxy branch is malformed — e.g. contains spaces, stray characters, or invalid escape sequences — so url.Parse(proxyURL) returns a non-nil error.

Common situations: Proxy env var set with surrounding whitespace or quotes pasted from a shell config; missing scheme handled elsewhere but an accidental 'http//:' typo breaks parsing; hostnames containing illegal characters from a template substitution.

Understand the failure class

Background: "Invalid URL" errors: why new URL(), URI.parse, and reqwest::Url reject your string — missing scheme, whitespace, and bad path format — this error's family across 39 libraries.
