读取验证响应失败

Error message

读取验证响应失败: %w

What it means

The verification response body could not be read: io.ReadAll(resp.Body) failed after a successful HTTP exchange, so solveVerification wraps the error as 读取验证响应失败. This indicates the connection dropped mid-body or the server sent a malformed/truncated stream.

Solutions

1. Retry the whole verification flow (getDetailInfo already retries alternate candidate URLs)
2. Increase the request timeout so the read isn't cut off by ctx deadline
3. Verify no proxy/middlebox truncates responses; test with curl
4. Check the wrapped error — 'unexpected EOF' vs 'context deadline exceeded' points to different fixes

info, err := plugin.GetDetailInfo(ctx, url)
if err != nil && strings.Contains(err.Error(), "读取验证响应失败") {
    time.Sleep(time.Second)
    info, err = plugin.GetDetailInfo(ctx, url) // transient read failures usually succeed on retry
}

When it happens

Trigger: io.ReadAll(resp.Body) errors in solveVerification — server closed the connection prematurely, chunked encoding interrupted, or a proxy reset the stream during the challenge response download.

Common situations: Unstable network or flaky CDN; aggressive server-side connection limits killing keep-alive connections; middleboxes/proxies truncating responses; response is huge and the timeout/context expires mid-read.

Understand the failure class

Background: "failed to read file", EACCES, ENOENT and "could not read <path>" errors: when a program can't read a file from disk — this error's family across 49 libraries.
