通过酷Q实现qq机器人,实现qq客服、定时推送qq消息、群管理等功能
通过酷Q实现qq机器人,实现qq客服、定时推送qq消息、群管理等功能。方式:1.windows下载酷Q并安装http-api插件。 下载地址:https://pan.baidu.com/s/1qY55zp62.直接使用docker,通过wine运行在linux系统上。$ docker pull richardchien/cqhttp:latest $ mkdir coolq # 用于存储酷 Q 的程序文件 $ docker run -ti --rm --name cqhttp-test \ -v $(pwd)/coolq:/home/user/coolq \ # 将宿主目录挂载到容器内用于持久化酷 Q 的程序文件 -p 9000:9000 \ # noVNC 端口,用于从浏览器控制酷 Q -p 5700:5700 \ # HTTP API 插件开放的端口 -e COOLQ_ACCOUNT=123456 \ # 要登录的 QQ 账号,可选但建议填 -e CQHTTP_POST_URL=http://example.com:8080 \ # 事件上报地址 -e CQHTTP_SERVE_DATA_FILES=yes \ # 允许通过 HTTP 接口访问酷 Q 数据文件 richardchien/cqhttp:latest其中,CQHTTP_POST_URL、CQHTTP_SERVE_DATA_FILES 是用于配置插件运行的,格式为「CQHTTP_ + 插件配置项的大写」,具体的配置项,见 配置。然后访问 http://注意,默认情况下,容器启动时会检查是否已经存在 config 目录,如果不存在,则会将 CQHTTP_ 开头的环境变量写入到配置文件中;如果 config 目录存在,即不是首次启动,则不会做任何修改。因此,你可以在容器运行时手动修改配置文件,重启容器后仍然有效,这和旧版本的行为不一样!如果你要让容器每次启动时都使用环境变量重新创建配置文件,以保持插件行为和容器启动命令的一致性,可以设置环境变量 FORCE_ENV 的值为 true。完成上述配置后即可通过调用api完成qq的发送消息及qq群管理等功能,剩下的具体的业务逻辑使用自己熟悉的语言去实现即可。详细的接口文档:https://richardchien.gitee.io/coolq-http-api/附点餐小呆萌代码:/** * 接收事件上报 * @throws \think\db\exception\DataNotFoundException * @throws \think\db\exception\ModelNotFoundException * @throws \think\exception\DbException */ public function receive(){ try{ $getData = input('post.') ? : file_get_contents('php://input'); if (!empty($getData['group_id']) && (int)$getData['group_id'] == $this->groupId) { if ($this->userId = $this->getGroupUserid()){ $content = $getData['raw_message'] ? : $getData['message']; //分离酷q的前置数据与内容文本 preg_match('/(.*[CQ:]{3}.*[]]{1})(.*)/u', $content, $arr); if (!empty($arr[1]) && !empty($arr[2])){ //提取前置数据中被@的qq号 preg_match('/(.*[CQ:at,qq=]{9})([0-9]{5,11})([]]{1})/u', $arr[1], $arr1); if (!empty($arr1[2]) && (int)$arr1[2] == 167114078){ //来到这里证明是被at了,取得纯文本内容进行下一步处理 $tasks = db("group_task") ->whereTime('create_time', 'today') ->select(); if (count($tasks)>=2){ preg_match_all("/([周]{1})([一二三四五六日]{1}).{0,3}([a-cA-C]{1}|[\u{4e0d}]{1}[\u{70b9}]{1})/u", $arr[2],$arr8); $dateArr = $this->getLastSevenDays(); if (!empty($arr8[2])) { //有选项 $data = []; //获取任务id与时间的对应数组,用于判断用户输入的时间有没有任务 $taskArr = array_column($tasks, 'id', 'time'); foreach ($arr8[2] as $key => $value) { $data[strtotime($dateArr[$this->changeDateType($value)])] = $arr8[3][$key]; if (!empty($taskArr[strtotime($dateArr[$this->changeDateType($value)])])){ $taskId = $taskArr[strtotime($dateArr[$this->changeDateType($value)])]; $this->order($taskId, $arr8[3][$key]); }else{ $this->sendGroup($this->groupId, "{$this->groupUserInfo['user_name']}周{$value},没有可点套餐。"); } } }else{ //无选项 preg_match('/([不]{1}[点]{1})/u', $arr[2],$arr2); preg_match('/([A-Ca-c])/u', $arr[2], $arr3); if (!empty($arr2[0]) && $arr2[0] == "不点" || !empty($arr3[0]) && in_array(ucfirst($arr3[0]), ['A', 'B', 'C'])){ $lists = []; $listsNote = []; foreach ($tasks as $v){ $lists[] = "周".$this->changeDateType((int)date("w", $v['time'])); $listsNote[] = "周".$this->changeDateType((int)date("w", $v['time'])) .

mysql优化之thread_cache_size
1、mysql服务器的线程数查看方法:show global status like 'Thread%';Threads_created:创建过的线程数,如果发现Threads_created值过大的话,表明MySQL服务器一直在创建线程,这也是比较耗资源,可以适当增加配置文件中thread_cache_size值2、优化参数thread_cache_sizethread_cache_size:当客户端断开之后,服务器处理此客户的线程将会缓存起来以响应下一个客户而不是销毁(前提是缓存数未达上限)即可以重新利用保存在缓存中线程的数量,当断开连接时如果缓存中还有空间,那么客户端的线程将被放到缓存中,如果线程重新被请求,那么请求将从缓存中读取,如果缓存中是空的或者是新的请求,那么这个线程将被重新创建,如果有很多新的线程,增加这个值可以改善系统性能。thread_cache_size大小的设置:如果是短连接,适当设置大一点,因为短连接往往需要不停创建,不停销毁,如果大一点,连接线程都处于取用状态,不需要重新创建和销毁,所以对性能肯定是比较大的提升。对于长连接,不能保证连接的稳定性,所以设置这参数还是有一定必要,可能连接池的问题,会导致连接数据库的不稳定性,也会出现频繁的创建和销毁,但这个情况比较少,如果是长连接,可以设置成小一点,一般在50-100左右。物理内存设置规则:通过比较Connections 和 Threads_created 状态的变量,可以看到这个变量的作用。(-->表示要调整的值) 根据物理内存设置规则如下: 1G ---> 8 2G ---> 16 3G ---> 32 >3G ---> 64查询thread_cache_size设置show global status like'thread_cache_size';优化方法:1、mysql> set global thread_cache_size=162、编辑/etc/my.cnf 更改/添加thread_concurrency = 163、mysql kill线程mysqladmin start slave stop slave kill某个连接到mysqlServer的线程

解决 docker run 报错 oci runtime error
在部署新服务器运行docker镜像的时候遇到了报错,记录下解决方法。docker 启动容器报错:Error response from daemon: oci runtime error: container_linux.go:247: starting container process caused "process_linux.go:258: applying cgroup configuration for process caused \"Cannot set property TasksAccountingdocker 是通过 yum install docker安装的,搜了一把,原来是因为linux与docker版本的兼容性问题。那就卸载旧版本安装最新版试试。0.通过uname -r命令查看你当前的内核版本uname -r1.使用 root 权限登录 Centos。确保 yum 包更新到最新。sudo yum update2.卸载旧版本(如果安装过旧版本的话)sudo yum remove docker docker-common docker-selinux docker-engine3.安装需要的软件包, yum-util 提供yum-config-manager功能,另外两个是devicemapper驱动依赖的sudo yum install -y yum-utils device-mapper-persistent-data lvm24.设置yum源sudo yum-config-manager --add-repo https://download.docker.com/linux/centos/docker-ce.repo5.可以查看所有仓库中所有docker版本,并选择特定版本安装yum list docker-ce --showduplicates | sort -r6.安装dockersudo yum install docker-ce7.启动并加入开机启动sudo systemctl start dockersudo systemctl enable docker8.验证安装是否成功(有client和service两部分表示docker安装启动都成功了) docker version 经过以上一通操作,pull 一下镜像再执行docker run命令,问题解决。
