convert output string to map with golang

Question

Get the output as

 {
   ARN: "arn:aws:secretsmanager:us-east-2:xxxx:secret:team_dev-Xhzkt6",
   CreatedDate: 2018-07-05 06:50:07 +0000 UTC,
   Name: "team_dev",
   SecretString: "{\"password\":\"test\"}",
   VersionId: "6b65bfe4-7908-474b-9ae6-xxxx",
   VersionStages: ["AWSCURRENT"]
 }

Try to get the value as map with the key SecretString

d.Set("secret_string", output.SecretString)

How can I get it as Schema TypeMap?

With jq, I can easily get it, but not sure how to do this in golang.

Updates

Thanks, @mkopriva

in the aws sdk (github.com/aws/aws-sdk-go/service/secretsmanager/api.go), output (GetSecretValueOutput) is defined as type:"structure"

type GetSecretValueOutput struct {
        _ struct{} `type:"structure"`

And thanks again to provide a test code, I will try it.

package main

import (
    "encoding/json"
    "fmt"
)

func main() {
    secretString := "{\"password\":\"test\"}"

    sec := map[string]interface{}{}
    if err := json.Unmarshal([]byte(secretString), &sec); err != nil {
        panic(err)
    }
    fmt.Println(sec)
}

Golang Playground Try Here

If output is map[string]interface{}, then output["SecretString"]. The returned value's type will be interface{} so you need to type assert it to a string. — mkopriva

get this error: invalid operation: output["SecretString"] (type *secretsmanager.GetSecretValueOutput does not support indexing) — Bill

Looking at the source (github.com/aws/aws-sdk-go/blob/master/service/secretsmanager/…) it seems you can do what you were doing in the first place but you need to dereference the field since it is a pointer. Try d.Set("secret_string", *output.SecretString) but first make sure it's not nil. — mkopriva

Thanks, please answer this question, so I can vote and accept it.

With your sample code, I did fix the issue.

-       d.Set("secret_string", output.SecretString)
+       var sec map[string]interface{}
+       if err = json.Unmarshal([]byte(*output.SecretString), &sec); err != nil {
+               return err
+       }
+       d.Set("secret_string", sec)
