我建议使用json.Unmarshal() 我试着打印id，希望它有帮助:

var jsonString = `{"Id": 1, "Title": "the title", "Name": "the name","Data": "the data","Commits" : "the commits"}`
var jsonData = []byte(jsonString)

var data Project

var err = json.Unmarshal(jsonData, &data)
if err != nil {
    fmt.Println(err.Error())
    return
}

fmt.Println("Id :", data.Id)

p = Project{...}
fmt.Printf("%+v", p)
fmt.Printf("%#v", p) //with type

有时，将结构体打印为有效的Go代码(相当于Go /ast代码)可能会很方便。出于这个目的，https://github.com/hexops/valast做得很好:

package main

import (
    "fmt"

    "github.com/hexops/valast"
)

type ProjectData struct {
    Title   string `json:"title"`
    Name    string `json:"name"`
    Data    string `json:"data"`
    Commits string `json:"commits"`
}

type Project struct {
    Id   int64        `json:"project_id"`
    Data *ProjectData `json:"data"`
}

func main() {
    p := Project{
        Id: 1,
        Data: &ProjectData{
            Title:   "Test",
            Name:    "Mihai",
            Data:    "Some data",
            Commits: "Test Message",
        },
    }
    fmt.Println(valast.String(p))
}

输出:

go run main.go 
Project{Id: 1, Data: &ProjectData{
        Title:   "Test",
        Name:    "Mihai",
        Data:    "Some data",
        Commits: "Test Message",
}}

不使用外部库，每个字段后加新行:

log.Println(
            strings.Replace(
                fmt.Sprintf("%#v", post), ", ", "\n", -1))

fmt.Println("%+v", structure variable)

更好的方法是在名为“commons”(可能)的包中为字符串“%+v”创建一个全局常量，并在代码中处处使用它

//In commons package
const STRUCTURE_DATA_FMT = "%+v"

//In your code everywhere
fmt.Println(commons.STRUCTURE_DATA_FMT, structure variable)

我想推荐Go -spew，根据他们的github“为Go数据结构实现了一个深度漂亮的打印机，以帮助调试”

go get -u github.com/davecgh/go-spew/spew

使用的例子:

package main

import (
    "github.com/davecgh/go-spew/spew"
)

type Project struct {
    Id      int64  `json:"project_id"`
    Title   string `json:"title"`
    Name    string `json:"name"`
    Data    string `json:"data"`
    Commits string `json:"commits"`
}

func main() {

    o := Project{Name: "hello", Title: "world"}
    spew.Dump(o)
}

输出:

(main.Project) {
 Id: (int64) 0,
 Title: (string) (len=5) "world",
 Name: (string) (len=5) "hello",
 Data: (string) "",
 Commits: (string) ""
}
