Function isBinary

command/v7/curl_command.go:83–94

isBinary determines if the provided `data` is likely binary content. It first checks if the given `contentType` (e.g., from an HTTP header) is a known binary MIME type. If not, it then scans the `data` byte slice for the presence of null bytes (0x00), which are a strong heuristic for binary data. Re

(response *http.Response, data []byte)

// which are a strong heuristic for binary data.
// Returns `true` if identified as binary, `false` otherwise.
func isBinary(response *http.Response, data []byte) bool {
	responseContextType := ""
	if response != nil && response.Header != nil {
		responseContextType = response.Header.Get("Content-Type")
	}
	if strings.Contains(responseContextType, "image/") ||
		strings.Contains(responseContextType, "application/octet-stream") ||
		strings.Contains(responseContextType, "application/pdf") {
		return true
	}
	return bytes.ContainsRune(data, 0x00) // Check for null byte
