基于SpringBoot、Docker和阿里云的稀土掘金社区自动签到与自动抽奖脚本：设计、开发与部署实践

创建一个SpringBoot项目

添加依赖

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 ? * *";@Resourceprivate 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<String> list = JSONUtil.toBean(str, List.class);List<String> list = JsonUtils.toObject(str, List.class);if (CommUtil.isEmpty(list)) {return "失败";}Map<String, String> header = Maps.newHashMap();//签到任务接口String url = "https://api.juejin.cn/growth_api/v1/check_in";for (String id : list) {//你的cookieString juejinCookie =id;RequestBody requestBody = new FormBody.Builder().build();String post = post(url, juejinCookie, requestBody, header);log.info("执行成功的cookie：{},执行结果为：：{}", id, post);}return "成功";}//post请求的工具类方法public static String post(String url, String cookie, RequestBody requestBody, Map<String, String> header) throws Exception {String userAgent = "okhttp/3.12.1;jdmall;android;version/10.3.4;build/92451;";OkHttpClient client = new OkHttpClient().newBuilder().build();Request request = new Request.Builder().url(url).post(requestBody).headers(Headers.of(header)).addHeader("Cookie", cookie).addHeader("User-Agent", userAgent).addHeader("Content-Type", "application/x-www-form-urlencoded; charset=UTF-8").addHeader("Cache-Control", "no-cache").addHeader("connection", "Keep-Alive").addHeader("accept", "*/*").build();Response response = client.newCall(request).execute();String result = response.body().string();log.info("post请求,result:{}", result);return result;}@SneakyThrows@GetMapping("lottery-draw")@ApiOperation("抽奖")@Scheduled(cron = DRAW_TIME)public String lotteryDraw() throws Exception {log.info("掘金自动抽奖开始");String str = redisServiceUtil.get(JUEJIN + COOKIE);//List<String> list = JSONUtil.toBean(str, List.class);List<String> list = JsonUtils.toObject(str, List.class);if (CommUtil.isEmpty(list)) {return "失败";}Map<String, String> header = Maps.newHashMap();//抽奖接口String drawUrl = "https://api.juejin.cn/growth_api/v1/lottery/draw";for (String id : list) {//你的cookieString juejinCookie =id;RequestBody requestBody = new FormBody.Builder().build();String response = post(drawUrl, juejinCookie, requestBody, header);log.info("执行成功的cookie：{},执行结果为：：{}", id, response);}return "success";}@PostMapping@ApiOperation("存cookie")public String set(@org.springframework.web.bind.annotation.RequestBody List<String> cookies) {String list = JSONUtil.toJsonStr(cookies);redisServiceUtil.set(JUEJIN + ":cookie", list);return "success";}
}

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
