核心挑战:
当企业拥有数千个员工号时,如何高效分配任务、监控在线状态并防止内存溢出?这需要一套精密的调度逻辑。
实战代码示例(Node.js):
以下代码展示了如何使用类(Class)封装 QiweAPI 实例,并实现一个基础的负载均衡调度器。

const axios = require('axios');

class QiweInstance {
    constructor(instanceId, apiKey) {
        this.instanceId = instanceId;
        this.apiKey = apiKey;
        this.baseUrl = "https://api.qiweapi.com/v1";
        this.isOnline = false;
    }

    // 初始化检查在线状态
    async checkStatus() {
        try {
            const res = await axios.post(`${this.baseUrl}/status`, {
                instanceId: this.instanceId,
                apiKey: this.apiKey
            });
            this.isOnline = res.data.success && res.data.status === 'online';
            return this.isOnline;
        } catch (err) {
            console.error(`实例 ${this.instanceId} 状态检查失败`);
            return false;
        }
    }

    // 发送消息方法封装
    async sendText(toUser, content) {
        if (!this.isOnline) throw new Error("实例不在线");
        return await axios.post(`${this.baseUrl}/sendText`, {
            instanceId: this.instanceId,
            apiKey: this.apiKey,
            toUser,
            content
        });
    }
}

// 调度器:管理多个实例
class QiweScheduler {
    constructor() {
        this.instances = [];
    }

    addInstance(id, key) {
        this.instances.push(new QiweInstance(id, key));
    }

    // 轮询算法:获取下一个可用的在线实例
    async getAvailableInstance() {
        for (let instance of this.instances) {
            if (await instance.checkStatus()) {
                return instance;
            }
        }
        return null;
    }

    // 批量群发任务
    async broadcast(userList, text) {
        for (let user of userList) {
            const runner = await this.getAvailableInstance();
            if (runner) {
                await runner.sendText(user, text);
                // 关键点:随机延迟 3-5 秒,模拟真人行为,绕过风控
                await new Promise(resolve => setTimeout(resolve, Math.random() * 2000 + 3000));
            }
        }
    }
}
