我正在尝试使用eosjs部署EOS智能合约。
我引用了https://eosio.github.io/eosjs/latest/how-to-guides/how-to-deploy-a-smart-contract中的代码
const wasmFilePath = './hello.wasm'
const abiFilePath = './hello.abi'
const fs = require('fs')
const { Api, JsonRpc, Serialize } = require('eosjs');
const { JsSignatureProvider } = require('eosjs/dist/eosjs-jssig'); // development only
const fetch = require('node-fetch'); //node only
const { TextDecoder, TextEncoder } = require('util'); //node only
let privateKey1 = '5J***********'
const privateKeys = [privateKey1];
const signatureProvider = new JsSignatureProvider(privateKeys);
const rpc = new JsonRpc('https://jungle2.cryptolions.io:443', { fetch }); //required to read blockchain state
const api = new Api({ rpc, signatureProvider, textDecoder: new TextDecoder(), textEncoder: new TextEncoder() });
const wasmHexString = fs.readFileSync(wasmFilePath).toString('hex')
const buffer = new Serialize.SerialBuffer({
textEncoder: api.textEncoder,
textDecoder: api.textDecoder,
})
let abiJSON = JSON.parse(fs.readFileSync(abiFilePath, 'utf8'))
const abiDefinitions = api.abiTypes.get('abi_def')
abiJSON = abiDefinitions.fields.reduce(
(acc, { name: fieldName }) =>
Object.assign(acc, { [fieldName]: acc[fieldName] || [] }),
abiJSON
)
abiDefinitions.serialize(buffer, abiJSON)
let serializedAbiHexString = Buffer.from(buffer.asUint8Array()).toString('hex')
deployContract();
async function deployContract(){
try{
const wasmFilePath = './hello.wasm'
const abiFilePath = './hello.abi'
const fs = require('fs')
const { Api, JsonRpc, Serialize } = require('eosjs');
const { JsSignatureProvider } = require('eosjs/dist/eosjs-jssig'); // development only
const fetch = require('node-fetch'); //node only
const { TextDecoder, TextEncoder } = require('util'); //node only
let privateKey1 = '5J***********'
const privateKeys = [privateKey1];
const signatureProvider = new JsSignatureProvider(privateKeys);
const rpc = new JsonRpc('https://jungle2.cryptolions.io:443', { fetch }); //required to read blockchain state
const api = new Api({ rpc, signatureProvider, textDecoder: new TextDecoder(), textEncoder: new TextEncoder() });
const wasmHexString = fs.readFileSync(wasmFilePath).toString('hex')
const buffer = new Serialize.SerialBuffer({
textEncoder: api.textEncoder,
textDecoder: api.textDecoder,
})
let abiJSON = JSON.parse(fs.readFileSync(abiFilePath, 'utf8'))
const abiDefinitions = api.abiTypes.get('abi_def')
abiJSON = abiDefinitions.fields.reduce(

Object.assign(acc, { [fieldName]: acc[fieldName] || [] }),
abiJSON
)
abiDefinitions.serialize(buffer, abiJSON)
let serializedAbiHexString = Buffer.from(buffer.asUint8Array()).toString('hex')
deployContract();
async function deployContract(){
try{
await api.transact(
{
actions: [
{
account: 'eosio',
name: 'setcode',
authorization: [
{
actor: user_name,
permission: 'active',
},
],
data: {
account: user_name,
code: wasmHexString,
},
},
{
account: 'eosio',
name: 'setabi',
authorization: [
{

permission: 'active',
},
],
data: {
account: user_name,
abi: serializedAbiHexString,
},
},
],
},
{
blocksBehind: 3,
expireSeconds: 30,
}
)
}
catch(e){
console.log(e)
}
};
};
我收到以下错误：
PS E：\ EOSIO \ smartcontract>节点。\ deploySmartContract.js
错误：缺少setcode.vmtype（type = uint8）
在Object.serializeStruct [序列化时]（E：\ EOSIO \ node_modules \ eosjs \ dist \ eosjs-serialize.js：571：27）
在serializeActionData（E：\ EOSIO \ node_modules \ eosjs \ dist \ eosjs-serialize.js：1041：12）
在Object.serializeAction（E：\ EOSIO \ node_modules \ eosjs \ dist \ eosjs-serialize.js：1051：15）
在Api。 （E：\ EOSIO \ node_modules \ eosjs \ dist \ eosjs-api.js：278：71）
在步骤（E：\ EOSIO \ node_modules \ eosjs \ dist \ eosjs-api.js：47：23）
在Object.next（E：\ EOSIO \ node_modules \ eosjs \ dist \ eosjs-api.js：28：53）
在完成时（E：\ EOSIO \ node_modules \ eosjs \ dist \ eosjs-api.js：19：58）
在process._tickCallback（内部/进程/next_tick.js:68:7）

在setcode的数据字段中添加vmtype和vmversion。
