Run ABI Get Method
Run ABI compatible get methods
With low level SDK get method is executed in 3 steps:
- 1.Download the latest Account State (BOC)
- 2.Encode message that calls the method
- 3.Execute the message locally on the downloaded state:
Here is the sample that executes the get method
getTimestamp on the latest account's state.- 1.account boc is downloaded with
blockchainAPI - 2.message that calls contract's function
getTimestampis encoded withencode_messagefunction - 3.message is executed on local TVM with
run_tvmmethod
async function getAccount(address) {
// `boc` or bag of cells - native blockchain data layout. Account's boc contains full account state (code and data) that
// we will need to execute get methods.
const query = `
query {
blockchain {
account(
address: "${address}"
) {
info {
balance(format: DEC)
boc
}
}
}
}`
const {result} = await client.net.query({query})
const info = result.data.blockchain.account.info
return info
}
async function runGetMethod(methodName, address, accountState) {
// Execute the get method `getTimestamp` on the latest account's state
// This can be managed in 3 steps:
// 1. Download the latest Account State (BOC)
// 2. Encode message
// 3. Execute the message locally on the downloaded state
// Encode the message with `getTimestamp` call
const { message } = await client.abi.encode_message({
// Define contract ABI in the Application
// See more info about ABI type here:
// https://github.com/tonlabs/ever-sdk/blob/master/docs/reference/types-and-methods/mod_abi.md#abi
abi: {
type: 'Contract',
value: HelloWallet.abi,
},
address,
call_set: {
function_name: methodName,
input: {},
},
signer: { type: 'None' },
});
// Execute `getTimestamp` get method (execute the message locally on TVM)
// See more info about run_tvm method here:
// https://github.com/tonlabs/ever-sdk/blob/master/docs/reference/types-and-methods/mod_tvm.md#run_tvm
console.log('Run `getTimestamp` get method');
const response = await client.tvm.run_tvm({
message,
account: accountState,
abi: {
type: 'Contract',
value: HelloWallet.abi,
},
});
return response.decoded.output
}
