我设法使我的 api 请求异步,但随后在尝试将其实现到主项目中时收到此错误。这意味着我做错了什么?
错误
Exception has occurred: SynchronousOnlyOperation
You cannot call this from an async context - use a thread or sync_to_async.
File "C:\Users\Admin\Desktop\djangoProjects\dguac\Signal.py", line 124, in main
await asyncio.wait([sigBuy(count) for count, bot in enumerate(activeBots)])
File "C:\Users\Admin\Desktop\djangoProjects\dguac\Signal.py", line 126, in <module>
loop.run_until_complete(main())
我不明白这个错误意味着什么以及我将如何修复它。
这是我的代码
async def sigBuy(count):
bot_dict = Bot.to_dict(activeBots[count])
sigSettings_dict = Bot.to_dict(activeBots[count].sigSettings)
# Binance API and Secret Keys
Bclient = CryptoXLib.create_binance_client(sigSettings_dict['API_key'], sigSettings_dict['API_secret_key'])
p = round(float(percentage(7, bot_dict['ct_balance']) / (float(bin_asset_price['price']) / 1)), 8)
# Round and Asign the asset_amount
asset_amount = round(p, 2)
# shouldILog = await makeBuy(market, asset_amount, Bclient, sigSettings_dict['base_currency'])
shouldILog = 2
if shouldILog == 2:
asset_amount = int(asset_amount)
last_trade = await Bclient.get_all_orders(pair = Pair(market, sigSettings_dict['base_currency']))
last_trade = last_trade['response'][-1]
print(last_trade)
# asset_price = float(last_trade['cummulativeQuoteQty']) / float(last_trade['executedQty'])
asset_price = 0.00000123
buyInPrice = float(last_trade['cummulativeQuoteQty'])
for otrade in activeBots[count].opentrades.all():
trade = Bot.to_dict(otrade)
del trade['id']
otradesUpdate.append(trade)
openTrades_dict = {'bot_ID': bot_dict['id'], 'date': date, 'market': market, 'trade_mode': 'Buy', 'price': asset_price, 'amount': asset_amount, 'amount_in_base_currency': buyInPrice, 'result': 0}
otradesUpdate.append(openTrades_dict)
BotsUpdate.append(bot_dict)
SigSettingsUpdate.append(sigSettings_dict)
await Bclient.close()
async def main():
await asyncio.wait([sigBuy(count) for count, bot in enumerate(activeBots)])
loop.run_until_complete(main())
答案 0 :(得分:3)
await asyncio.wait 似乎是正确的,因为你可以有一个可迭代的列表(即使 asyncio.wait 应该被弃用 iirc)但异常消息有点让我失望。 OP 应该做的是环绕 Django ORM 的查询集并让它执行,但 Django 的 ORM 延迟加载会导致一些问题。
错误的原始答案
你不是在等待正确的事情。你的意思是等待 sigBuy 但你的 asyncio.wait 正在等待。与此同时,您现在有一个尚未执行任何内容的协程列表。
我建议您尝试两件事:
asyncio.gather([sigBuy(count) for count, bot in enumerate(activeBots)])
[await sigBuy(count) for count, bot in enumerate(activeBots)]
答案 1 :(得分:0)
我通过使用解决了这个错误
void createVulkanSurface(SDL_Window* SDL_window, void* vkInstance, void* vkSurface);
并且首先将过滤和预取的 Django 查询中的每个项目附加到新的 activeBots 列表中,以便异步代码接受它。
