How to decode stellar XDR












0















I am working on stellar blockchain and need to decode stellar XDR which is in GO language. I know how to decode using JavaScript but couldn't find a way to do it in GO. 



 //JS code



 const {Transaction} = require('stellar-base')



 const parsedTx = new Transaction('tx_envelope_encoded_as_XDR')

 console.log(parsedTx)


This works fine. what i have tried and not working...



//GO code



import (



   "bytes"

   "encoding/json"

   "fmt"

   "net/http"

   "github.com/stellar/go/xdr"

   "github.com/gorilla/mux"



 )



func DecodeXDR(w http.ResponseWriter, r *http.Request) {



    var OBJ model.TransactionCollectionBody

    err := json.NewDecoder(r.Body).Decode(&OBJ)

    if err != nil {

      w.WriteHeader(http.StatusBadRequest)

      json.NewEncoder(w).Encode("Error while Decoding the body")

      fmt.Println(err)



      return

    }



    // fmt.Println(OBJ)



    // lol:=xdr.Value(OBJ.XDR)



    var txe xdr.Transaction

    err = xdr.SafeUnmarshalBase64(XDRB64, &txe)

    if err != nil {

      fmt.Println(err)

    }



    fmt.Println(txe)



}



//Output

{{PublicKeyTypePublicKeyTypeEd25519 0xc042055d20} 200 2800572080062465 <nil> {MemoTypeMemoNone <nil> <nil> <nil> <nil>} [{<nil> {OperationTypeManageData <nil> <nil> <nil> <nil> <nil> <nil> <nil> <nil> <nil> 0xc042174040 <nil>}} {<nil> {OperationTypeManageData <nil> <nil> <nil> <nil> <nil> <nil> <nil> <nil> <nil> 0xc042174080 <nil>}}] {0}}

  • I am using SafeUnmarshalBase64 to unmarshal the XDR which is in base 64 format and it gives an byte stream output shown above as //Output. But what i actually want is something (set of operations performed under that public key) which is readable like //Expected Output.

  • It seems that you can decode the transaction just fine, but your expectation makes no sense. xdr.Transaction has none of the fields shown in the expected output. Also Println produces the standard format for structs and that's not something resembling JavaScript.
