如果使用 Wrangler 部署,可通过在 Wrangler 文件中添加以下内容来设置 cron 语法(如下所示为每小时一次):
{
"$schema": "./node_modules/wrangler/config-schema.json",
"name": "worker",
// ...
"triggers": {
"crons": [
"0 * * * *"
]
}
}"$schema" = "./node_modules/wrangler/config-schema.json"
name = "worker"
[triggers]
crons = [ "0 * * * *" ]你也可以在 Wrangler 配置文件中为每个环境设置不同的 Cron Trigger。需要将 [triggers] 表放在所选环境下方。例如:
{
"env": {
"dev": {
"triggers": {
"crons": [
"0 * * * *"
]
}
}
}
}[env.dev.triggers]
crons = [ "0 * * * *" ]测试 Cron Triggers 的推荐方式是使用 Wrangler。
可以使用 Wrangler 测试 Cron Triggers:向 wrangler dev 传入 --test-scheduled 标志。这会暴露 /__scheduled(Python Workers 为 /cdn-cgi/handler/scheduled)路由,可通过 HTTP 请求测试。要模拟不同的 cron 模式,可传入 cron 查询参数。
npx wrangler dev --test-scheduled
curl "http://localhost:8787/__scheduled?cron=0+*+*+*+*"
curl "http://localhost:8787/cdn-cgi/handler/scheduled?cron=*+*+*+*+*" # Python Workers
