英文:
Unable to parse this json file in golang
问题
我正在尝试编写Go代码来解析以下JSON文件的内容：
{"peers": [{"pid": 1,"address": "127.0.0.1:17001"},{"pid": 2,"address": "127.0.0.1:17002"}]}
到目前为止，我写了以下代码：
package mainimport ("fmt""io/ioutil""encoding/json")type Peer struct {Pid intAddress string}type Config struct {Peers []Peer}func main() {content, err := ioutil.ReadFile("config.json")if err != nil {fmt.Print("Error:", err)}var conf Configerr = json.Unmarshal(content, &conf)if err != nil {fmt.Print("Error:", err)}fmt.Println(conf)}
上述代码可以解析非嵌套的JSON文件，例如以下文件：
{"pid": 1,"address": "127.0.0.1:17001"}
但是，即使我多次更改了Config结构体，我仍然无法解析问题开头提到的JSON文件。请问有人可以告诉我如何继续吗？

I am trying to write go code to parse the following of json file:
{"peers": [{"pid": 1,"address": "127.0.0.1:17001"},{"pid": 2,"address": "127.0.0.1:17002"}]}
What I could do so far is write this code:
package mainimport ("fmt""io/ioutil""encoding/json")type Config struct{Pid intAddress string}func main(){content, err := ioutil.ReadFile("config.json")if err!=nil{fmt.Print("Error:",err)}var conf Configerr=json.Unmarshal(content, &conf)if err!=nil{fmt.Print("Error:",err)}fmt.Println(conf)}
Above code works for non-nested json files like following one:
{"pid": 1,"address": "127.0.0.1:17001"}
But even after changing the Config struct so many times. I am not able to parse the json file mentioned at the start of the question. Can somebody please tell me how to proceed?

你可以使用以下结构定义来映射你的JSON结构：
type Peer struct{Pid intAddress string}type Config struct{Peers []Peer}

You can use the following struct definition to map your JSON structure:
type Peer struct{Pid intAddress string}type Config struct{Peers []Peer}

要包含自定义属性名称，请添加结构字段标签，如下所示：
type Peer struct {CustomId int `json:"pid"`CustomAddress string `json:"address"`}
这样，当将Peer结构体转换为JSON时，属性名称将被自定义为pid和address。
英文:
To include custom attribute names, add struct field tags as:
type Peer struct{CustomId int `json:"pid"`CustomAddress string `json:"address"`}
