如何从NEAR中的区块中获取所有事务？

import json
import requests

def get_transactions_from_block(block_hash):
    url = "https://rpc.nearprotocol.com"
    payload = {
        "jsonrpc": "2.0",
        "id": "1",
        "method": "block",
        "params": [block_hash, True]
    }
    headers = {
        "Content-Type": "application/json"
    }

    response = requests.post(url, data=json.dumps(payload), headers=headers)
    if response.status_code == 200:
        block_data = response.json()["result"]
        transactions = block_data["transactions"]
        return transactions
    else:
        return []

block_hash = "block_hash"
transactions = get_transactions_from_block(block_hash)

from near import Block, Account

def get_transactions_from_block(block_hash):
    block = Block(block_hash)
    transactions = []
    for tx in block.transactions:
        transaction = {
            "sender": Account(tx.sender),
            "receiver": Account(tx.receiver),
            "amount": tx.amount
            # 其他事务相关信息
        }
        transactions.append(transaction)
    return transactions

block_hash = "block_hash"
transactions = get_transactions_from_block(block_hash)
