client.ts中复制以下代码
const wallet pg.wallet;
const program pg.program;
const counterSeed Buffer.from(counter);const counterPubkey await web3.PublicKey.findProgramAddressSync([counterSeed],pg.PROGRAM_ID
);const initializeTx await pg.program.methods.initialize().accounts({counter: counterPubkey[0],authority: pg.wallet.publicKey,systemProgram: web3.SystemProgram.programId,}).rpc();let counterAccount await program.account.counter.fetch(counterPubkey[0]);
console.log(account after initializing , Number(counterAccount.count));const incrementTx await pg.program.methods.increment().accounts({counter: counterPubkey[0],authority: pg.wallet.publicKey,}).rpc();counterAccount await program.account.counter.fetch(counterPubkey[0]);
console.log(account after increasing , Number(counterAccount.count));部署和发布
切换到左侧工具栏第二个按钮并点击 build点击deploy, 终端出现 “Deployment successful.” 即为部署成功。这大约会消耗2~3个sol
测试交互
切换到左侧第一个文件按钮并点击 Run 运行client.ts文件输出如图
再次执行就会开始报错
Running client… client.ts: Uncaught error: failed to send transaction: Transaction simulation failed: Error processing Instruction 0: custom program error: 0x0
各种求助之后修改初始化代码输出报错日志
try {// Initialize accountconst initializeTx await pg.program.methods.initialize().accounts({counter: counterPubkey,authority: pg.wallet.publicKey,systemProgram: web3.SystemProgram.programId,}).rpc();} catch (error) {console.error(Error fetching counter account:, error);}报错日志如下 logs: [ Program CVQCRMyzWNr8MbNhzjbfPu9YVvr97onF48Lc9ZwXotpW invoke [1],Program log: Instruction: Initialize,Program 11111111111111111111111111111111 invoke [2],Allocate: account Address { address: 8sKt2NcKbN9E2SUE6E3NgfzwGi5ByBZxHQdCw27bMef1, base: None } already in use,Program 11111111111111111111111111111111 failed: custom program error: 0x0,Program CVQCRMyzWNr8MbNhzjbfPu9YVvr97onF48Lc9ZwXotpW consumed 4867 of 200000 compute units,Program CVQCRMyzWNr8MbNhzjbfPu9YVvr97onF48Lc9ZwXotpW failed: custom program error: 0x0 ],programErrorStack: { stack: [ [Object], [Object] ] } }根据日志信息关键的错误是
Allocate: account Address { address: 8sKt2NcKbN9E2SUE6E3NgfzwGi5ByBZxHQdCw27bMef1, base: None } already in use这表示你尝试分配的账户地址 8sKt2NcKbN9E2SUE6E3NgfzwGi5ByBZxHQdCw27bMef1 已经被使用因此无法进行新的初始化。这通常发生在你已经为该地址创建了账户但可能在再次执行时未考虑到这一点。
修改initializeTx代码
let counterAccount;
try {counterAccount await program.account.counter.fetch(counterPubkey);console.log(Counter account already exists:, counterAccount);
} catch (error) {if (error.message.includes(Account does not exist)) {console.log(Counter account does not exist, proceeding with initialization...);// Initialize accountconst initializeTx await pg.program.methods.initialize().accounts({counter: counterPubkey,authority: pg.wallet.publicKey,systemProgram: web3.SystemProgram.programId,}).rpc();} else {console.error(Error fetching counter account:, error);}
}执行结果
修复后完整client.ts代码
const wallet pg.wallet;
const program pg.program;
const counterSeed Buffer.from(counter);const [counterPubkey, bump] web3.PublicKey.findProgramAddressSync([counterSeed],pg.PROGRAM_ID
);let counterAccount;
try {counterAccount await program.account.counter.fetch(counterPubkey);console.log(Counter account already exists:, counterAccount);
} catch (error) {if (error.message.includes(Account does not exist)) {console.log(Counter account does not exist, proceeding with initialization...);// Initialize accountconst initializeTx await pg.program.methods.initialize().accounts({counter: counterPubkey,authority: pg.wallet.publicKey,systemProgram: web3.SystemProgram.programId,}).rpc();} else {console.error(Error fetching counter account:, error);}
}const incrementTx await pg.program.methods.increment().accounts({counter: counterPubkey,authority: pg.wallet.publicKey,}).rpc();counterAccount await program.account.counter.fetch(counterPubkey);
console.log(account after increasing , Number(counterAccount.count));
