transactions 相关问题

我正在尝试创建一个 solana 机器人，它具有使用 raydium 购买 $MAGA 的限价订单。但是，每次我运行代码时，事务都不会完成。 # Returns the swap_transaction to be manipulated in sendTransaction() async def create_transaction(quote: dict, input_token_mint, output_token_mint) -> dict: log_transaction.info(f"""Soltrade is creating transaction for the following quote: {quote}""") if 'error' in quote: log_transaction.error(f"Error in quote: {quote['error']}") raise Exception(f"Error in quote: {quote['error']}") pool_id = get_pool_id(input_token_mint) #pool_id = "9XsGAA3xHC6gqRgThRrcaUPU6jzerZacWgfyMb17579t" # Parameters used for the Raydium POST request parameters = { "quoteResponse": quote, "userPublicKey": str(configs['public_address']), "wrapUnwrapSOL": True, "computeUnitPriceMicroLamports": 20 * 3_000_000 # fee of roughly $.4 :shrug: } #9XsGAA3xHC6gqRgThRrcaUPU6jzerZacWgfyMb17579t # Returns the JSON parsed response of Jupiter async with httpx.AsyncClient() as client: response = await client.post(f"https://api.raydium.io/v2/swap?poolId={pool_id}", json=parameters) exchange_data = response.json() pprint(f"TRANSACTION CREATE:\n{exchange_data}") return exchange_data async def perform_swap(sent_amount: float, price_limit, sent_token_mint: str, mode : str): global position log_general.info("Soltrade is taking a limit position.") #TODO: fetch the current price and create a limit order current_price = get_price(sent_token_mint) base_token = await get_token_decimals(sent_token_mint) quote = trans = opts = txid = tx_error = None is_tx_successful = False for i in range(0,3): if not is_tx_successful: try: if (mode == "buy") or (mode == "sell"): quote = await create_exchange(sent_amount, sent_token_mint, mode) trans = await create_transaction(quote, sent_token_mint, SOL_MINT_ADDRESS) print(f"TRANS:\n{trans}") opts = TxOpts(skip_preflight=False, preflight_commitment="confirmed", last_valid_block_height=find_last_valid_block_height()) txid = send_transaction(trans["swapTransaction"], opts) for i in range(3): await asyncio.sleep(35) tx_error = find_transaction_error(txid) if not tx_error: is_tx_successful = True break else: log_general.info(f"Price hasn't reached {price_limit}.

Retrying. 我尝试过调试，增加滑点和费用。我研究了任何 Solana python 文档，但找不到任何文档。我认为问题可能是链接错误。我碰巧通过切换到 Jupiter api 并使用这些链接来解决这个问题：这个在create_exchange()： https://quote-api.jup.ag/v6/quote?inputMint={input_token_mint}&outputMint={output_token_mint}&amount={int(amount_in)}&slippageBps={config().slippage} 这个在create_transaction()： https://quote-api.jup.ag/v6/swap
