如何在Golang中初始化嵌套结构数组?

How to initialize nested structure array in golang?

问题

这个问题类似,我试图使用一些默认值初始化以下结构:

type Configuration struct {
    Val   string
    Proxy []struct {
        Address string
        Port    string
    }
}

有没有一种方法可以在不单独声明Proxy的情况下完成这个操作?

英文:

Similar to this question, I'm try to initialize the following structure with some default values:

type Configuration struct {
    Val   string
    Proxy []struct {
        Address string
        Port    string
    }
}

Is there a way to do this without declaring Proxy separately?

你可以这样初始化它:

cfg := Configuration{
	Val: "foo",
	Proxy: []struct {
		Address string
		Port    string
	}{
		{Address: "a", Port: "093"},
	},
}
英文:

You can initialize it as such

cfg := Configuration{
	Val: "foo",
	Proxy: []struct {
		Address string
		Port    string
	}{
		{Address: "a", Port: "093"},
	},
}

是的,但是由于你必须在某个地方声明类型,所以它看起来有点(主观上)丑陋:

c := Configuration{
	Val: "value",
	Proxy: []struct {
		Address string
		Port    string
	}{
		{"addr1", "2"},
		{"addr2", "4"},
	},
}
英文:

Yes, but since you have to declare the type somewhere, it gets (subjectively) ugly:

c := Configuration{
	Val: "value",
	Proxy: []struct {
		Address string
		Port    string
	}{
		{"addr1", "2"},
		{"addr2", "4"},
	},
}
