julia - 什么是 Julia 中 connect 的替代品？

Question

julia> conn = connect(1234)

ERROR: UndefVarError: connect not defined
Stacktrace:
 [1] top-level scope at REPL[1]:1

更新后它不起作用，所以是否有任何新关键字被替换？

help?> connect
search: continue countlines count_ones

Couldn't find connect
Perhaps you meant convert, collect, const, count or conj
  No documentation found.

  Binding connect does not exist.

在尝试将预先存在的代码移植到 julia 1.x 时，Julia 0.7 版是一个方便的工具:对于 Julia 1.0.0 中已弃用的所有函数，julia 0.7 中会显示警告。

在connect的具体情况下:

julia> connect
WARNING: Base.connect is deprecated: it has been moved to the standard library package `Sockets`.
Add `using Sockets` to your imports.
 in module Main
connect (generic function with 8 methods)

按照此消息中提供的信息，connect现在应该用作:

using Sockets
socket = connect(1234)
