Swift信号资源使用云编译用户数据脚本
导 言
云编程用户可应用Swift信号资源帮助判定用户数据脚本状况执行Swift信号资源增加功能表示用户数据脚本完成与否,如果完成,则表示成功或失败
使用OS::Heat::SwiftSignal资源协调资源生成信号来自栈外部或内部源资源常与OS::Heat::SwiftSignalHandle资源库
使用SwiftSignalHandle资源创建临时URL应用脚本发送信号上头Swift信号资源等待该URL接收数定数余信定时内信号华体会联盟hth临时URL使用racspace云创建
文件整理
后续教程引导你经历单节点Linux服务器构建过程,该服务器信号成败用户数据脚本执行
添加顶级模板段
顶部模板添加以下信息:
template_version:2014-10-16描述:资源:输出
添加
SwiftSignalHandle资源库
SwiftSignalHandle资源库
资源节中增加SwiftSignalHandle资源库下代码示例显示如何添加此资源
信号-handle:类型:OS:Heat:SwiftSignalHandle
添加
Swift信号资源库
Swift信号资源库
资源节中增加Swift信号资源库
提供 URL控件属性和信号数计数属性
下示例显示如何添加Swift信号资源等待600秒接收信号控件.
wait_on_server:类型OS:Heat:SwiftSignal属性栈标记为故障超时属性或非信号余信接收数据字符串和推理字符串可附加成败通知数据串是一个属性,可显示为模板输出
添加服务器资源
添加Linux服务器内用户数据属性,包括块脚本脚本执行尾端发送余信或费城消息传递到临时URLSwiftSignalHandle资源,你
前面加法

添加Swift信号URL
输出段内
输出段内
下示例显示如何向鼠标添加Swift信号URL输出段数 :
# 获取信号 URL中包含传递到信号句sesse_url:值 { get_atr:[sit_handle,curl_cli]}描述 Swift信号 URL#获取描述脚本结果的数据NULL信号data:值 { get_atr:[sit_onserver','dad'}描述:数据描述脚本结果#获取IPv4服务器地址_public_ip:值 { get_atr:[linux_server访问IP4]}描述:Linux服务器公共IP
