英文:
Parsing JSON in Golang doesn't Populate Object
问题
作为Oauth应用程序的一部分，我需要解码一些JSON数据。但是我无法获取到填充的对象。没有出现错误，但数据就是不在那里。我尝试了很多不同的方法...
我已经在http://play.golang.org/p/QGkcl61cmv上重新创建了这个问题。
import ("encoding/json""fmt""strings")type RefreshTokenData struct {id string `json:"id"`issued_at string `json:"issued_at"`scope string `json:"scope"`instance_url string `json:"instance_url"`token_type string `json:"token_type"`refresh_token string `json:"refresh_token"`signature string `json:"signature"`access_token string `json:"access_token"`}func main() {var tokenResp = `{"id":"https://google.com","issued_at":"1423698767063","scope":"full refresh_token","instance_url":"https://na15.salesforce.com","token_type":"Bearer","refresh_token":"2os53__CCU5JX_yZXE","id_token":"5jSH0Oqm7Q4fc0xkE9NOvW8cA13U","signature":"/599EkGVIBsKPFRNkg+58wZ3Q7AFyclvIGvCrxVeyTo=","access_token":"sadfasdfasdfasdfdsa"}`var tokenData RefreshTokenDatadecoder := json.NewDecoder(strings.NewReader(tokenResp))if jsonerr := decoder.Decode(&tokenData); jsonerr != nil {fmt.Println("****Failed to decode json")} else {fmt.Println("****Refresh token: " + tokenData.refresh_token)}}
希望这可以帮助你解决问题。

As part of an Oauth application, I need to decode some JSON. But I cannot get the object populated. There is no failure, but the data just isn't there. I've tried a bunch of different ways...
I have recreated the problem at http://play.golang.org/p/QGkcl61cmv
import ("encoding/json""fmt""strings")type RefreshTokenData struct {id string `json:"id"`issued_at string `json:"issued_at"`scope string `json:"scope"`instance_url string `json:"instance_url"`token_type string `json:"token_type"`refresh_token string `json:"refresh_token"`signature string `json:"signature"`access_token string `json:"access_token"`}func main() {var tokenResp = `{"id":"https://google.com","issued_at":"1423698767063","scope":"full refresh_token","instance_url":"https://na15.salesforce.com","token_type":"Bearer","refresh_token":"2os53__CCU5JX_yZXE","id_token":"5jSH0Oqm7Q4fc0xkE9NOvW8cA13U","signature":"/599EkGVIBsKPFRNkg+58wZ3Q7AFyclvIGvCrxVeyTo=","access_token":"sadfasdfasdfasdfdsa"}`var tokenData RefreshTokenDatadecoder := json.NewDecoder(strings.NewReader(tokenResp))if jsonerr := decoder.Decode(&tokenData); jsonerr != nil {fmt.Println("****Failed to decode json")} else {fmt.Println("****Refresh token: " + tokenData.refresh_token)}}

type RefreshTokenData struct {Id string `json:"id"`Issued_at string `json:"issued_at"`Scope string `json:"scope"`Instance_url string `json:"instance_url"`Token_type string `json:"token_type"`Refresh_token string `json:"refresh_token"`Signature string `json:"signature"`Access_token string `json:"access_token"`}
英文:
The JSON encoding package works with exported fields only. Capitalize the field names to export them:
type RefreshTokenData struct {Id string `json:"id"`Issued_at string `json:"issued_at"`Scope string `json:"scope"`Instance_url string `json:"instance_url"`Token_type string `json:"token_type"`Refresh_token string `json:"refresh_token"`Signature string `json:"signature"`Access_token string `json:"access_token"`}
