初始化嵌套的结构定义 [英] Initialize nested struct definition

问题描述

如何初始化以下结构?

type Sender struct {
    BankCode string
    Name     string
    Contact  struct {
        Name    string
        Phone   string
    }
}

我尝试过:

s := &Sender{
        BankCode: "BC",
        Name:     "NAME",
        Contact {
            Name: "NAME",
            Phone: "PHONE",
        },
    }

不起作用:

mixture of field:value and value initializers
undefined: Contact

我尝试过:

s := &Sender{
        BankCode: "BC",
        Name:     "NAME",
        Contact: Contact {
            Name: "NAME",
            Phone: "PHONE",
        },
    }

不起作用:

undefined: Contact

推荐答案

您的Contact是具有匿名结构类型的字段.因此，您必须重复类型定义:

Your Contact is a field with anonymous struct type. As such, you have to repeat the type definition:

s := &Sender{
    BankCode: "BC",
    Name:     "NAME",
    Contact: struct {
        Name  string
        Phone string
    }{
        Name:  "NAME",
        Phone: "PHONE",
    },
}

但是在大​​多数情况下，最好将单独的类型定义为rob74建议.

But in most cases it's better to define a separate type as rob74 proposed.
