php小编草莓在这里为大家解答一个关于Go语言的疑问:在运行`go version -m`命令时,输出中的箭头符号"=>"代表的含义是什么呢?这个符号实际上是用来表示包的依赖关系的。当我们使用`go mod`进行包管理时,箭头符号会显示模块之间的依赖关系,指示一个模块依赖于另一个模块。通过这个符号,我们可以清晰地了解到每个模块之间的关联关系,方便我们进行包的管理和调试。
我正在解析各种扫描仪在我的项目中识别出的 cve,其中一个 cve 与 golang 依赖项的版本相关联。
当我运行 go version -m ./binaryfile
时,被标记为易受攻击的依赖项旁边有这个箭头符号 =>
,但我找不到任何地方记录它的含义。
完整的输出包含在下面...

...感兴趣的线是:

=>
表示使用 replace
指令构建可执行二进制文件。
前一行也很重要,那就是替换的模块:
dep github.com/docker/docker v1.13.1 => github.com/docker/engine v17.12.0-ce-rc1.0.20190717161051-705d9623b7c1+incompatible h1:4pnn+rsurveibbmqlrtzh77hlmip4naaqrhook4apj8=
这意味着 github.com/docker/docker v1.13.1
在构建过程中被 github.com/docker/engine v17.12.0-...
替换。
来自 go.mod
文件的 replace
指令示例:
replace golang.org/x/net v1.2.3 => example.com/fork/net v1.4.5
这就是 =>
文字的来源。将其视为所引用的 golang.org/x/net
包“指向” example.com/fork/net
(这就是实际使用的内容)。
