shouldRetry method

bool shouldRetry(
  1. DioException error,
  2. int attemptNumber
)

判断是否应该重试

Implementation

bool shouldRetry(DioException error, int attemptNumber) {
  if (attemptNumber >= maxAttempts) return false;

  // 检查网络相关错误（连接、超时等）
  final isNetworkError =
      error.type == DioExceptionType.connectionError ||
      error.type == DioExceptionType.connectionTimeout ||
      error.type == DioExceptionType.receiveTimeout ||
      error.type == DioExceptionType.sendTimeout;

  if (isNetworkError) return true;

  // 如果配置为只重试网络错误，则不检查HTTP状态码
  if (retryOnlyNetworkErrors) return false;

  // 检查HTTP响应错误
  if (error.type == DioExceptionType.badResponse) {
    final statusCode = error.response?.statusCode;
    if (statusCode != null && retryableStatusCodes.contains(statusCode)) {
      return true;
    }
  }

  return false;
