decodeControlPlaneResponse function

Map<String, dynamic> decodeControlPlaneResponse(int httpStatus, String body)

解析控制面响应。非 2xx 或业务码非 0 时抛 SyImControlPlaneException。

Implementation

Map<String, dynamic> decodeControlPlaneResponse(int httpStatus, String body) {
  Object? parsed;
  try {
    parsed = jsonDecode(body.isEmpty ? '{}' : body);
  } on FormatException {
    parsed = null;
  }
  final ok = httpStatus >= 200 && httpStatus < 300;
  if (parsed is! Map) {
    if (ok) {
      throw SyImControlPlaneException(-1, httpStatus, 'unexpected response');
    }
    throw SyImControlPlaneException(httpStatus, httpStatus, 'HTTP $httpStatus');
  }
  final m = Map<String, dynamic>.from(parsed);
  final rawCode = m['code'];
  final code = rawCode is num ? rawCode.toInt() : (ok ? 0 : httpStatus);
  if (!ok || code != 0) {
    final msg = m['msg']?.toString();
    throw SyImControlPlaneException(code, httpStatus,
        (msg == null || msg.isEmpty) ? 'HTTP $httpStatus' : msg);
  }
  final data = m['data'];
  if (data is Map) return Map<String, dynamic>.from(data);
  if (data == null) return <String, dynamic>{};
  return <String, dynamic>{'value': data};
}
