首页请求返回状态码

Error message

首页请求返回状态码: %d

What it means

getFormhash returns this error when the homepage responds with a non-200 HTTP status. The library treats any non-OK status as fatal for formhash extraction since the HTML will not contain the expected form.

Solutions

1. Log resp.StatusCode and set a browser-like User-Agent in setRequestHeaders
2. Back off and retry later if rate-limited (429)
3. Check the response body for Cloudflare/captcha challenges and consider cookie warming
4. Verify the site is healthy (check in a browser)
5. Follow redirects properly (ensure client.CheckRedirect is default)

Example fix

// before
req.Header.Set("User-Agent", "go-http-client")
// after
req.Header.Set("User-Agent", "Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/120 Safari/537.36")

resp, err := http.Get(BaseURL)
if err == nil && resp.StatusCode != 200 {
    // site is returning errors/blocked; skip search or alert
}

if err != nil && strings.Contains(err.Error(), "首页请求返回状态码") {
    var statusErr interface{ Error() string }
    _ = statusErr
    // inspect status code in message: back off on 429, alert on 5xx
}

When it happens

Trigger: client.Do succeeds but resp.StatusCode != 200 — e.g., 403 (bot blocking), 429 (rate limited), 5xx (server error), 30x handled oddly, or a challenge page.

Common situations: Site WAF/Cloudflare blocking the default User-Agent, IP rate limiting after frequent searches, temporary server outage, or being redirected to a login/captcha page.
