go - How to define a map in TOML?

Question

How to define a map in TOML?

For example, I want to define something like:

[FOO]

Usernames_Passwords='{"user1":"pass1","user2":"pass2"}'

and then in go convert them to a map[string]string

Answer 1

你可以有这样的地图：

name = { first = "Tom", last = "Preston-Werner" }
point = { x = 1, y = 2 }

见：https ://github.com/toml-lang/toml#user-content-inline-table

在您的情况下，您似乎需要一个密码表或一组地图。你可以这样：

[[user_entry]]
name = "user1"
pass = "pass1"

[[user_entry]]
name = "user2"
pass = "pass2"

或更简洁地说：

user_entry = [{ name = "user1", pass = "pass1" },
              { name = "user2", pass = "pass2" }]

这适用于 github.com/BurntSushi/toml（不支持内联表）：

d := `
    [FOO.Usernames_Passwords]
    a="foo"
    b="bar"
    `
var s struct {
    FOO struct {
        Usernames_Passwords map[string]string
    }
}
_, err := toml.Decode(d, &s)
// check err!
fmt.Printf("%+v", s)

使用github.com/naoina/toml这有效（使用内联表）：

d := `
    [FOO]
    Usernames_Passwords = { a = "foo" , b = "bar" }
    `
var s struct {
    FOO struct {
        Usernames_Passwords map[string]string
    }
}
err := toml.Unmarshal([]byte(d), &s)
if err != nil {
    panic(err)
}
fmt.Printf("%+v", s)
