[ ] 读取响应失败

Error message

[%s] 读取响应失败: %w

What it means

searchPage wraps the error from io.ReadAll(resp.Body): the response body could not be fully read from the network connection. Because defer resp.Body.Close() runs right after, this typically means the connection dropped mid-transfer (unexpected EOF, connection reset by peer) or the compressed/encoded stream was corrupt.

Solutions

Check the wrapped error (unexpected EOF vs context deadline vs connection reset)
Retry the search — transient truncation often succeeds on a second attempt
Increase MaxRetries in doRequestWithRetry to cover mid-body drops
Increase TimeoutSeconds if the deadline is being hit on large pages
Ensure no misconfigured proxy is intercepting and truncating traffic

Defensive patterns

Strategy: retry

Try / catch

results, err := p.Search(keyword, ext)
if err != nil && strings.Contains(err.Error(), "读取响应失败") {
    // transient body read failure: retry with backoff
    time.Sleep(time.Second)
    results, err = p.Search(keyword, ext)
}

Prevention

Enable the plugin's built-in retry (MaxRetries) for transient truncation
Increase TimeoutSeconds on slow links so large pages finish downloading
Avoid unreliable proxies that terminate connections mid-body
Retry once automatically — these failures are usually transient

When it happens

Trigger: io.ReadAll(resp.Body) fails after a 200 response: server closed the connection mid-body, TLS truncation, proxy interference, or an interrupted read hitting the 30s context deadline.

Common situations: Flaky upstream site or CDN dropping large HTML pages; overloaded server truncating responses; NAT/firewall killing long-lived connections; unstable network on the host running pansou.
