TypeError: provider.send不是锚中的函数

Question

我正在看这个https://book.solmeet.dev/notes/intro-to-anchor，它是根据教科书中的代码编写的：

等待TypeError: provider.send is not a function时provider.send()

​

import * as anchor from '@project-serum/anchor';
import { Program } from '@project-serum/anchor';
import { AnchorEscrow } from '../target/types/anchor_escrow';
import { PublicKey, SystemProgram, Transaction } from '@solana/web3.js';
import { TOKEN_PROGRAM_ID, Token } from "@solana/spl-token";
import { assert } from "chai";

describe('anchor-escrow', () => {

  // Configure the client to use the local cluster.
  const provider = new anchor.getProvider();
  anchor.setProvider(provider);

  const program = anchor.workspace.AnchorEscrow as Program<AnchorEscrow>;

  let mintA = null;
  let mintB = null;
  let initializerTokenAccountA = null;
  let initializerTokenAccountB = null;
  let takerTokenAccountA = null;
  let takerTokenAccountB = null;
  let vault_account_pda = null;
  let vault_account_bump = null;
  let vault_authority_pda = null;

  const takerAmount = 1000;
  const initializerAmount = 500;

  const escrowAccount = anchor.web3.Keypair.generate();
  const payer = anchor.web3.Keypair.generate(); 
  const mintAuthority = anchor.web3.Keypair.generate();
  const initializerMainAccount = anchor.web3.Keypair.generate();
  const takerMainAccount = anchor.web3.Keypair.generate();

  it("Initialize program state", async () => {
    // Airdropping tokens to a payer.
    await provider.connection.confirmTransaction(
      await provider.connection.requestAirdrop(payer.publicKey, 10000000000),
      "confirmed"
    );

    // ⚠️ An error has occurred here
    await provider.send(
      (() => {
        const tx = new Transaction();
        tx.add(
          SystemProgram.transfer({
            fromPubkey: payer.publicKey,
            toPubkey: initializerMainAccount.publicKey,
            lamports: 100000000,
          }),
          SystemProgram.transfer({
            fromPubkey: payer.publicKey,
            toPubkey: takerMainAccount.publicKey,
            lamports: 100000000,
          })
        );
        return tx;
      })(),
      [payer]
    );
});

​

然后运行anchor test

我该如何解决这个问题？

Answer 1

看起来似乎不存在send，但是如果您也想确认超限，可以使用sendAndConfirm，如果只想发送，则可以使用sendAll。这需要一系列事务，所以您可以：

        const tx = new Transaction();
        tx.add(
          SystemProgram.transfer({
            fromPubkey: payer.publicKey,
            toPubkey: initializerMainAccount.publicKey,
            lamports: 100000000,
          }),
          SystemProgram.transfer({
            fromPubkey: payer.publicKey,
            toPubkey: takerMainAccount.publicKey,
            lamports: 100000000,
          })
        );
        await provider.sendAll([{tx, signers: [payer]}]);
