我是Haskell的新手,我正在使用Stack在Mac上构建一个小的个人项目。我最近在我的阴谋文件中添加了一些新的构建工具,但是现在当我运行stack build时,我得到了以下错误:
-- While attempting to add dependency,

我试图用dart代替python作为我的工具的脚本语言。我可以在任何地方创建python文件,导入全局包并运行它,但我似乎无法用dart来实现它。我总是需要一个pubspec.yaml文件来运行dart脚本吗?
这就是我要运行的脚本:

当我读到多动词单请求时:
这种攻击也是过度动词攻击策略的一个变体。攻击BOT创建多个HTTP请求,不是在单个HTTP会话期间一个接一个地发出HTTP请求,而是通过形成嵌入多个请求的单个数据包。
如何理解a single packet embedded with multiple requests?
这是否意味着一个HTTP请求包有多个HTTP请求?
