golang取消编码可解析为json的字符串

Question

How do I get this to work?

s, _ := url.QueryUnescape("%22%7B%5C%22sessionId%5C%22%3A%5C%225331b937-7b55-4c2d-798a-25e574a7e8af%5C%22%2C%5C%22userId%5C%22%3A2%2C%5C%22userName%5C%22%3A%5C%22datami_op%5C%22%2C%5C%22userEmail%5C%22%3A%5C%22datami_op%40example.com%5C%22%2C%5C%22userRoles%5C%22%3A%5B%5C%22operator%5C%22%5D%7D%22")
fmt.Println(s)
//s := "{\"sessionId\":\"5331b937-7b55-4c2d-798a-25e574a7e8af\",\"userId\":2,\"userName\":\"op\",\"userEmail\":\"[e-mail]\",\"userRoles\":[\"operator\"]}"
var i Info
err := json.Unmarshal([]byte(s), &i)
fmt.Println(i, err)

You can either manually remove the quoting yourself, as you have in your comment, or you could unmarshal first as a json string:

var unquote string
err := json.Unmarshal([]byte(s), &unquote)
fmt.Println(unquote, err)

var i Info 
err = json.Unmarshal([]byte(unquote), &i)
fmt.Println(i, err)
