    aid is a unique ID assigned by the Aegis SDK to each user device. It is stored in the localStorage of the browser and used to distinguish between users for UV calculation. It will be updated only when the user clears the browser cache.

    Prerequisites

    Install and initialize the Aegis SDK in any method as detailed in Installation and Initialization.

    aid

    You can use the following algorithm to customize the aid reporting rules:

    async getAid(callback: Function) {
    // In some cases, an error will occur when `localStorage` is manipulated
    try {
    let aid = await localStorage.getItem('AEGIS_ID');
    if (!aid) {
    aid = 'xxxxxxxx-xxxx-4xxx-yxxx-xxxxxxxxxxxx'.replace(/[xy]/g, (c) => {
    const r = (Math.random() * 16) | 0;
    const v = c === 'x' ? r : (r & 0x3) | 0x8;
    return v.toString(16);
    });
    localStorage.setItem('AEGIS_ID', aid);
    }
    callback?.(aid || '');
    } catch (e) {
    callback?.('');
    }
    }
    Note:

    To use the aid constructed by yourself as a reporting rule, you need to configure an aid verification rule in the format of /^[@=.0-9a-zA-Z_-]{4,36}$/ on the backend.
