rjob - A Simple Job Scheduler By Rust

一个简单的定时任务调度程序，支持HTTP请求任务。

快速开始

  1. 添加任务定义文件

    在可执行程序所在目录中添加任务定义文件，文件支持json/yaml两种类型。任务定义示例如下：

    jobs.json: json { "http_jobs": [ { "enable": true, "name": "users2", "cron": "*/5 * * * * ?", "request": { "url": "https://reqres.in/api/users/2", "method": "GET" } }, { "enable": true, "name": "login", "cron": "*/10 * * * * ?", "request": { "url": "https://reqres.in/api/login", "method": "POST", "headers": {}, "body": { "email": "eve.holt@reqres.in", "password": "cityslicka" } } } ] } jobs.yaml:
    ```yaml http_jobs:

    注意：

    1. 目录中只能有一个任务定义文件。
    2. request中的headers和body是可选参数。

  2. Linux 环境执行程序 bash ./rjob

  3. Linux nohup 命令执行程序 ```bash

    在后台运行程序，程序日志会被输出到nohup.out文件中

    nohup ./rjob &

    查看进程

    ps -aux | grep rjob

    结束进程

    kill -9 进程号PID ```

  4. 任务执行时会打印日志，可以通过每条日志开头的UUID跟踪任务执行情况。 bash 4cd4a467890646c9ac96cc15d3ad3ab9 2023-05-27 12:01:20.003 Http job start, job name: login 4cd4a467890646c9ac96cc15d3ad3ab9 2023-05-27 12:01:20.003 Job: [name: login, enable: true, cron: */10 * * * * ?, request: [url: https://reqres.in/api/login, method: POST, headers: None, body: {"email":"eve.holt@reqres.in","password":"cityslicka"}]] 5f00ef4403324c2692caddb51315f6ee 2023-05-27 12:01:20.003 Http job start, job name: users2 5f00ef4403324c2692caddb51315f6ee 2023-05-27 12:01:20.003 Job: [name: users2, enable: true, cron: */5 * * * * ?, request: [url: https://reqres.in/api/users/2, method: GET, headers: None, body: None]] 5f00ef4403324c2692caddb51315f6ee 2023-05-27 12:01:20.003 Http request success, job name: users2 5f00ef4403324c2692caddb51315f6ee 2023-05-27 12:01:20.003 Http response: {"data":{"id":2,"email":"janet.weaver@reqres.in","first_name":"Janet","last_name":"Weaver","avatar":"https://reqres.in/img/faces/2-image.jpg"},"support":{"url":"https://reqres.in/#support-heading","text":"To keep ReqRes free, contributions towards server costs are appreciated!"}} 5f00ef4403324c2692caddb51315f6ee 2023-05-27 12:01:20.003 Http job end, job name: users2 4cd4a467890646c9ac96cc15d3ad3ab9 2023-05-27 12:01:20.003 Http request success, job name: login 4cd4a467890646c9ac96cc15d3ad3ab9 2023-05-27 12:01:20.003 Http response: {"token":"QpwL5tke4Pnpja7X4"} 4cd4a467890646c9ac96cc15d3ad3ab9 2023-05-27 12:01:20.003 Http job end, job name: login

编译

编译x86_64 Linux可执行程序。

  1. 在项目中添加.cargo目录，添加config.toml文件，内容如下： toml [target.x86_64-unknown-linux-musl] linker = "x86_64-linux-musl-gcc"

  2. 添加编译目标x86_64-unknown-linux-musl。 bash rustup target add x86_64-unknown-linux-musl

  3. 查看编译目标列表 bash rustup target list

  4. 编译 bash cargo build --release --target=x86_64-unknown-linux-musl

编译ARM Linux可执行程序

  1. 在项目中添加.cargo目录，添加config.toml文件，内容如下： toml [target.aarch64-unknown-linux-musl] linker = "aarch64-linux-musl-ld"

  2. 添加编译目标aarch64-unknown-linux-musl。 bash rustup target add aarch64-unknown-linux-musl

  3. 查看编译目标列表 bash rustup target list

  4. 编译 bash cargo build --release --target=aarch64-unknown-linux-musl

遇到的问题

  1. MacOS环境交叉编译，需要安装 musl-cross。 bash brew install filosottile/musl-cross/musl-cross
  2. 在Debian/Ubuntu环境需要安装build-essential。 bash sudo apt install build-essential
  3. 在Debian/Ubuntu环境编译时报error: failed to run custom build command for 'ring v0.16.20'错误时，安装 musl-tools。 bash sudo apt install musl-tools
