Decoding json in Golang

问题

我无法解决你的代码问题,但我可以帮你翻译代码。以下是你提供的代码的翻译:

package main

import (
	"encoding/json"
	"fmt"
)

type ApiParams struct {
	AccessToken string `json:"access_token"`
	TokenType   string `json:"token_type"`
	ExpiresIn   int64  `json:"expires_in"`
}

func main() {
	data := `{
		"access_token": "asdfasdf",
		"token_type": "bearer",
		"expires_in": 5173885
	}`

	var apiParams ApiParams
	err := json.Unmarshal([]byte(data), &apiParams)
	if err != nil {
		fmt.Println(err)
	}
	fmt.Println(apiParams)
}

希望这可以帮助到你!

I cannot figure out what's wrong in my code to decode this json. It returns an empty struct. Go playground here: http://play.golang.org/p/K8WznLT5M0

package main

import (
	"encoding/json"
	"fmt"
)

type ApiParams struct {
	AccessToken string `json:access_token`
	TokenType   string `json:token_type`
	ExpiresIn   int64  `json:expires_in`
}

func main() {
	data := `{
    		"access_token": "asdfasdf",
    		"token_type": "bearer",
    		"expires_in": 5173885
	}`

	var apiParams ApiParams
	err := json.Unmarshal([]byte(data), &apiParams)
	if err != nil {
		fmt.Println(err)
	}
	fmt.Println(apiParams)
}

将标签添加双引号:

type ApiParams struct {
    AccessToken string `json:"access_token"`
    TokenType   string `json:"token_type"`
    ExpiresIn   int64  `json:"expires_in"`
}
英文:

Add double quotes to the tags:

type ApiParams struct {
    AccessToken string `json:"access_token"`
    TokenType   string `json:"token_type"`
    ExpiresIn   int64  `json:"expires_in"`
}

你的注释是错误的。你需要在JSON属性名称周围加上引号,像这样:

type ApiParams struct {
    AccessToken string `json:"access_token"`
    TokenType   string `json:"token_type"`
    ExpiresIn   int64  `json:"expires_in"`
}
英文:

Your annotations are wrong.. You need quotes around the json property names like;

type ApiParams struct {
    AccessToken string `json:"access_token"`
    TokenType   string `json:"token_type"`
    ExpiresIn   int64  `json:"expires_in"`
}
