创建GET请求失败

Error message

创建GET请求失败: %w

What it means

getFormhash wraps a failure from http.NewRequestWithContext when building the GET request for the site homepage used to extract formhash. This means the request object could not be constructed before any network I/O.

Solutions

1. Check the BaseURL constant is a valid absolute HTTP(S) URL
2. Print/log BaseURL to spot stray whitespace or invalid characters
3. Fix the URL value; this is a compile-time/config issue, not a runtime network issue

Example fix

// before
const BaseURL = "http://example.com base"
// after
const BaseURL = "http://example.com"

u, err := url.Parse(BaseURL)
if err != nil || u.Scheme == "" || u.Host == "" {
    // BaseURL is malformed; fix configuration before calling Search
}

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

When it happens

Trigger: http.NewRequestWithContext(ctx, "GET", BaseURL, nil) errors, which happens only when the method or URL is invalid — e.g., BaseURL fails url.Parse (malformed URL, control characters).

Common situations: BaseURL constant corrupted by an edit or bad build-time substitution, or accidentally containing whitespace/newlines/invalid characters.

Understand the failure class

Background: "Invalid URL" / "URL cannot be empty": fix the malformed or missing URL behind request-construction failures — this error's family across 50 libraries.
