[ ] POST搜索请求失败

Error message

[%s] POST搜索请求失败: %w

What it means

searchImpl wraps any failure from postSearchRequest, which POSTs the search keyword with the formhash to obtain the search-result URL. Failure means the POST request errored, returned an unexpected status, or the result URL could not be extracted.

Solutions

1. Confirm Step 1 succeeded and the formhash is fresh — always reuse the same sessionClient so cookies persist
2. Enable DebugLog to inspect the POST response status and body
3. Verify POST form field names still match the site's current search form
4. Add retries with backoff for transient network errors or rate limiting
5. Check for anti-bot/Cloudflare challenges in the response body

if err != nil && strings.Contains(err.Error(), "POST搜索请求失败") {
    // formhash may be stale or request blocked; redo full flow (fresh formhash) once
    return fullFlowWithRetry(ctx, keyword, 1)
}

When it happens

Trigger: p.postSearchRequest(sessionClient, keyword, formhash) fails during Step 2: HTTP request creation/transport error, non-OK response, empty response body, or failure to parse the returned search URL from the response.

Common situations: Invalid or expired formhash (session cookies lost), site rate-limiting or WAF blocking the POST, network timeouts, or site form field names changed so the server rejects the request.

Understand the failure class

Background: 'Something went wrong' / 'Request failed (500)' / 'HTTP error! status: 404' — what failed HTTP requests actually mean and how to find the real cause — this error's family across 28 libraries.
