如何在Golang中初始化嵌套结构？

Question

type important struct {
client     string                 `json:"client"`
Response   Summary        `json:"response"`

}

type Summary struct {
Name     string           `json:"name"`
Metadata Clientdata      `json:"metadata"`
}

type Clientdata struct {
Income string           `json:"income"` 
}


v := &important{ client: "xyz", Response:  Summary[{
            Name: "test",
            Metadata: Clientdata { "404040"},
        }
    }]

//Error: Cannot use Summary{ Name: "test", Metadata: Clientdata { "404040"}, } (type Summary) as type []Summary more...

What I am doing wrong here?

To put it simply, you goofed the syntax of a slice literal slightly. Your mistake is fairly logical, but sadly it doesn't work.

The following is a fixed version:

v := &important{ client: "xyz", Response: []Summary{
        {
            Name: "test",
            Metadata: Clientdata { "404040"},
        },
    },
}

A slice literal is defined like so:

[]type{ items... }
