read response body failed

Error message

read response body failed: %w

What it means

After the API responds, doSearch reads the entire response body with io.ReadAll. If the body cannot be read (connection dropped mid-response, read timeout, aborted transfer), the error is wrapped as "read response body failed".

Solutions

Inspect the wrapped error for "unexpected EOF" vs timeout to pick the fix
Retry the request on transient read errors
Check proxy/LB idle timeouts versus response time
Consider limiting response size with io.LimitReader to fail fast on anomalies

Example fix

// before
bodyBytes, err := io.ReadAll(resp.Body)
if err != nil {
	return nil, fmt.Errorf("read response body failed: %w", err)
}

// after
bodyBytes, err := io.ReadAll(io.LimitReader(resp.Body, 10<<20))
if err != nil {
	return nil, fmt.Errorf("read response body failed (status %d): %w", resp.StatusCode, err)
}

Defensive patterns

Strategy: retry

Try / catch

// Go
results, err := p.doSearch(ctx, keyword, ext)
if err != nil && strings.Contains(err.Error(), "read response body failed") {
	// transient read failure: retry once with backoff
}

Prevention

Use io.LimitReader to bound response size
Ensure client timeouts exceed slow-response times
Check intermediary proxy idle timeouts
Prefer HTTP/2 or keep-alive for stable connections

When it happens

Trigger: io.ReadAll(resp.Body) errors while draining the Jikepan API response: server closes connection early, network interruption mid-transfer, or read deadline exceeded.

Common situations: Unstable network/mobile connections; Jikepan server or an intermediary proxy truncating responses; very large responses hitting a client read timeout; TLS termination issues.
