读取下载结果失败: %w

Error message

读取下载结果失败: %w

What it means

Reading the marketplace response body with io.ReadAll failed. The connection was established and returned 200, but the body could not be fully read — typically a dropped/reset connection mid-transfer or a read timeout.

Solutions

1. Simply retry the download — this is usually transient
2. Check for proxy/LB timeouts between the server and the marketplace
3. Stabilize the network path (keepalive settings, MTU issues on VPN tunnels)
4. Inspect the wrapped error: 'unexpected EOF' or 'connection reset by peer' indicates mid-body disconnect

if err := DownloadOnlineSkill(ctx, req); err != nil && strings.Contains(err.Error(), "读取下载结果失败") {
    // body read interrupted; retry the download, it is transient
}

When it happens

Trigger: Calling DownloadOnlineSkill when the marketplace (or an intermediary proxy/LB) closes the TCP connection before the full JSON body arrives, or the body is truncated by a network interruption.

Common situations: Flaky network between server and marketplace; aggressive proxy idle timeouts; very large responses interrupted by LB body limits.
