英文:
Convert func to string literal in golang
问题
我有一些保存在变量中的函数，并且我需要将它转换为字符串字面量：
testFunc := func(orgId int64) bool {
return false
}
期望的结果字符串字面量如下所示：
resultStr := `func(orgId int64) bool {
return false
}`
以下是我尝试过的方法：
testFuncStr := reflect.ValueOf(testFunc).String()
然而，这只会得到以下字面量：
"<func(int64) bool Value>"
英文:
I have some func saved in a variable and I need to convert it into a string literal:
testFunc := func(orgId int64) bool {
return false
}
The expected result string literal is like this:
resultStr := `func(orgId int64) bool {
return false
}`
Here is what I have tried:
testFuncStr := reflect.ValueOf(testFunc).String()
However this only get me the following literal:
"<func(int64) bool Value>",

根据@BurakSerdar的说法，Go语言不是一种解释型语言，而是编译型语言，所以你可以做的事情相对有限。reflect是一个强大的包，你可以获取函数名称、函数参数的数量，甚至可以获取调用栈（用于日志记录），但你永远无法从构建的二进制文件中获取函数的源代码。
英文:
As @BurakSerdar said - Go is not a language which is interpreted, but compiled, so there's rather limited amount of stuff you can do. reflect is a powerful package - you can get function names, number of function arguments, and even call stack (which is handy for logging), but you will never be able to obtain a source code of a function from within a build binary.
