¿Cómo implementar un contrato inteligente influenciado por entradas de UI usando ConseilJS y Michelson generado por SmartPy?

Deseopoder crear un contratointeligentetomando datos de unainterfaz de usuarioparaproporcionar losparámetros pubKey,prvKey,pubHashpara laimplementación y minAmount y maxTimeparainfluiren Michelson.

Tengoel siguiente JS:

 function deploy(input_dict){
    const tezosNode='https://rpcalpha.tzbeta.net/';
    const conseilServer={url:'https://conseil-dev.cryptonomic-infra.tech:443',apiKey:'foo',network:'babylonnet'};

    async function contract() {
      const keystore = {
          publicKey:input_dict['pubKey'],
          privateKey:input_dict['prvKey'],
          publicKeyHash:input_dict['tz1-address'],
          seed:'',
          storeType:conseiljs.StoreType.Fundraiser
      };
      const michelson=`parameter (or (or (nat %divisor) (unit %double)) (nat %value));
        storage (nat %storedValue);
        code {
          DUP; CDR; SWAP; CAR;
          IF_LEFT {
            IF_LEFT {
              PAIR; DUP; CAR; PUSH nat 5; SWAP; COMPARE; GT;
              IF { }
              { PUSH string "WrongCondition: params.divisor > 5"; FAILWITH; };
              DUP; CDR; DUUP; CAR; EDIV;
              IF_SOME { CAR; }
              { PUSH string "division by zero"; FAILWITH; };
              SWAP; DROP; NIL operation; PAIR;
            }
            { PAIR; DUP; CDR; PUSH nat 2; MUL; SWAP; DROP; NIL operation; PAIR; };
          }
          { PAIR; DUP; CAR; SWAP; DROP; NIL operation; PAIR; };
        }`;
      const storage='"Sample"';
      const nodeResult = await conseiljs.TezosNodeWriter.sendContractOriginationOperation(tezosNode, keystore, 0, undefined, false, true, 100000, '', 1000, 100000, michelson, storage, conseiljs.TezosParameterFormat.Michelson);
      const groupid = nodeResult['operationGroupID'].replace(/\"/g, '').replace(/\n/, ''); // clean up RPC output
      console.log(`Injected operation group id ${groupid}`);
      const conseilResult = await conseiljs.TezosConseilClient.awaitOperationConfirmation(conseilServer, 'alphanet', groupid, 5);
      console.log(`Originated contract at ${conseilResult[0].originated_accounts}`);
    }
    contract();
 

Actualmente,cuando seejecuta,produce los siguienteserrores:

 GET https://rpcalpha.tzbeta.net//chains/main/blocks/head/context/contracts/foo/counter 403

Access to fetch at 'https://rpcalpha.tzbeta.net//chains/main/blocks/head/context/contracts/foo/counter' from origin 'null' has been blocked by CORS policy: No 'Access-Control-Allow-Origin' header is present on the requested resource. If an opaque response serves your needs, set the request's mode to 'no-cors' to fetch the resource with CORS disabled.

Sinembargo,estoy seguro de queestos sonmenos relevantes ya queel códigoes obviamenteincorrectoen suforma actual.

Este código se derivaen granmedida de los documentos de Cryptonomic ,perotodavíame quedanoestoy seguro demuchoselementos:

• ¿seed:''es correcta?
• ¿storeType:conseiljs.StoreType.Fundraiseres correcto?
• ¿Cuálesel valor de const storage='"Sample"'?

En relación con lainteracción con Michelson. Fuegenerado yembellecido con SmartPy.io yen los casos deprueba seproporcionanentradas queinfluyenen el almacenamiento dentro del contratointeligente:

 def __init__(self,pubHash,minAmount,maxTime):
    self.init(fund=sp.bigMap(tkey=sp.TAddress,tvalue=sp.TMutez),
        owner=pubHash,minAmount=minAmount,maxTime=maxTime,balance=sp.tez(0))
 

¿Cómo se realizaestamismainteracción conel Michelson queestá representadoestáticamenteen el JS?

¡Se agradecemucho cualquier ayuda!

I wish to be able to create a smart contract taking input from a UI to supply parameters pubKey,prvKey,pubHash for the deployment and minAmount and maxTime to influence the Michelson.

I have the following JS:

function deploy(input_dict){
    const tezosNode='https://rpcalpha.tzbeta.net/';
    const conseilServer={url:'https://conseil-dev.cryptonomic-infra.tech:443',apiKey:'foo',network:'babylonnet'};

    async function contract() {
      const keystore = {
          publicKey:input_dict['pubKey'],
          privateKey:input_dict['prvKey'],
          publicKeyHash:input_dict['tz1-address'],
          seed:'',
          storeType:conseiljs.StoreType.Fundraiser
      };
      const michelson=`parameter (or (or (nat %divisor) (unit %double)) (nat %value));
        storage (nat %storedValue);
        code {
          DUP; CDR; SWAP; CAR;
          IF_LEFT {
            IF_LEFT {
              PAIR; DUP; CAR; PUSH nat 5; SWAP; COMPARE; GT;
              IF { }
              { PUSH string "WrongCondition: params.divisor > 5"; FAILWITH; };
              DUP; CDR; DUUP; CAR; EDIV;
              IF_SOME { CAR; }
              { PUSH string "division by zero"; FAILWITH; };
              SWAP; DROP; NIL operation; PAIR;
            }
            { PAIR; DUP; CDR; PUSH nat 2; MUL; SWAP; DROP; NIL operation; PAIR; };
          }
          { PAIR; DUP; CAR; SWAP; DROP; NIL operation; PAIR; };
        }`;
      const storage='"Sample"';
      const nodeResult = await conseiljs.TezosNodeWriter.sendContractOriginationOperation(tezosNode, keystore, 0, undefined, false, true, 100000, '', 1000, 100000, michelson, storage, conseiljs.TezosParameterFormat.Michelson);
      const groupid = nodeResult['operationGroupID'].replace(/\"/g, '').replace(/\n/, ''); // clean up RPC output
      console.log(`Injected operation group id ${groupid}`);
      const conseilResult = await conseiljs.TezosConseilClient.awaitOperationConfirmation(conseilServer, 'alphanet', groupid, 5);
      console.log(`Originated contract at ${conseilResult[0].originated_accounts}`);
    }
    contract();

Currently when run it produces the following errors:

GET https://rpcalpha.tzbeta.net//chains/main/blocks/head/context/contracts/foo/counter 403

Access to fetch at 'https://rpcalpha.tzbeta.net//chains/main/blocks/head/context/contracts/foo/counter' from origin 'null' has been blocked by CORS policy: No 'Access-Control-Allow-Origin' header is present on the requested resource. If an opaque response serves your needs, set the request's mode to 'no-cors' to fetch the resource with CORS disabled.

Uncaught (in promise) TypeError: Failed to fetch

However, these I'm sure are less relevant as the code is obviously incorrect in its current form.

This code is heavily derived from the docs of Cryptonomic but I am still left unsure about many elements:

• is seed:'' correct?
• is storeType:conseiljs.StoreType.Fundraiser correct?
• what is the value of const storage='"Sample"' for?

In relation to interacting with the Michelson. It was generated and prettified with SmartPy.io and in the test cases there are inputs supplied which influence storage within the smart contract:

def __init__(self,pubHash,minAmount,maxTime):
    self.init(fund=sp.bigMap(tkey=sp.TAddress,tvalue=sp.TMutez),
        owner=pubHash,minAmount=minAmount,maxTime=maxTime,balance=sp.tez(0))

How is this same interaction performed with the Michelson that is statically represented in the JS?

Any help is much appreciated!
