编写自动签到代码

@Api(tags = "掘金")
@RestController
@RequestMapping("/jue-jin")
@Slf4j
@ResponseInfoSkin
public class JueJin {
    public static final String COOKIE = ":cookie";

    public static final String JUEJIN="juejin";
    // 每天9点15中开始执行
    public static final String IN_TIME = "0 15 09 ? * *";
    // 每天9点17中开始执行
    public static final String DRAW_TIME = "0 17 09 ? * *";
    @Resource
    private RedisServiceUtil redisServiceUtil;

    @SneakyThrows
    @GetMapping("sign-in")
    @ApiOperation("签到")
    @Scheduled(cron = IN_TIME)
    public String signIn() {
        log.info("掘金自动签到开始");
        String str = redisServiceUtil.get(JUEJIN + COOKIE);
        //List list = JSONUtil.toBean(str, List.class);
        List<String> list = JsonUtils.toObject(str, List.class);
        if (CommUtil.isEmpty(list)) {

        OkHttpClient client = new OkHttpClient().newBuilder()

swagger 接口

如何找到自己的掘金cookie

复制自己的cookie

粘贴到接口：存cookie

定时：@Scheduled(cron = IN_TIME)

这个注解就不在这里展开了

编写Dockerfile

FROM eclipse-temurin:8-jre

## 创建目录，并使用它作为工作目录
RUN mkdir -p /home/project/kkxx-poi
WORKDIR /home/project/kkxx-poi
## 将后端项目的 Jar 文件，复制到镜像中
COPY ./kkxx-poi-1.1-SNAPSHOT.jar app.jar

## 设置 TZ 时区
## 设置 JAVA_OPTS 环境变量，可通过 docker run -e "JAVA_OPTS=" 进行覆盖
ENV TZ=Asia/Shanghai JAVA_OPTS="-Xms128m -Xmx512m"

## 暴露后端项目的 9091 端口
EXPOSE 9091

#  -Djava.security.egd=file:/dev/./urandom 这是加快生成随机数的配置
# https://blog.csdn.net/qq_39581637/article/details/122719838
## 启动后端项目
CMD java ${JAVA_OPTS}  -jar app.jar

复制到自己服务器某个目录

构建镜像

docker build -f /home/project/Dockerfile -t kkxx-poi-image:test .

启动镜像

docker run -d --name kkxx-poi-name -p 9092:9091 kkxx-poi-image:test
