9e41f4b71Sopenharmony_ci**Reason for Change**
10e41f4b71Sopenharmony_ci
11e41f4b71Sopenharmony_ciThe purpose of this change is to standardize the range of domain names for atomic service requests and improve the atomic service release efficiency and platform operation security. When a user initiates an atomic service request, domain name access is subject to the domain name configured for the atomic service. If no domain name is configured, the **connect** API returns the error code 2302998.

15e41f4b71Sopenharmony_ciThis change is a non-compatible change.
16e41f4b71Sopenharmony_ci
17e41f4b71Sopenharmony_ciIf no domain name is configured for atomic services of API version 11 or earlier, the **connect** API is not affected.
18e41f4b71Sopenharmony_ci
19e41f4b71Sopenharmony_ciFrom API version 12, the **connect** API throws this error code for access to a domain name not configured for an atomic service. For details, see [API Reference](../../../application-dev/reference/apis-network-kit/js-apis-webSocket.md).

36e41f4b71Sopenharmony_ci
37e41f4b71Sopenharmony_ciIf you use the **webSocket.connect** API for connection setup when developing an atomic service, you need to go to [AppGallery Connect](https://developer.huawei.com/consumer/en-us/service/josp/agc/index.html)
38e41f4b71Sopenharmony_cito configure the server domain name. For details, see [Development Guide](https://developer.huawei.com/consumer/en-us/doc/atomic-guides-V5/agc-help-harmonyos-server-domain-V5).
39e41f4b71Sopenharmony_ci
40e41f4b71Sopenharmony_ciIf the **webSocket.connect** API fails during atomic service development, use **catch** to capture the error. If the error code is **2302998**, configure the server domain name in [AppGallery Connect](https://developer.huawei.com/consumer/en-us/service/josp/agc/index.html). For details, see [Development Guide](https://developer.huawei.com/consumer/en-us/doc/atomic-guides-V5/agc-help-harmonyos-server-domain-V5).
