我正在WINAPI上写。我无法通过 websocket 接收数据。它以前有效，但发生了变化。首先，我连接到 tesnet.binancefuture.com/ws-fapi/v1 并获取监听密钥。然后我连接到stream.binance.com，但没有任何反应。我之前发过，现在显示错误。
{
"method": "REQUEST",
"params":
[
"<listenKey>@account", // request name 1
"<listenKey>@balance" // request name 2, if existing
],
"id": 12 // request ID.
}
它起作用了。
我写了 hook useTheme，我们将有标准主题：黑暗和光明。但我还想添加一个“创建主题”按钮，当您单击它时，将新主题添加到自定义主题；默认情况下，我们添加的所有主题都被禁用。如果我们已经包含了自定义主题，则不需要添加属性data-theme，而只需获取其中的所有内容details并将其传递给setProperty.键是我们的类型--background, --color，值是颜色。您能帮助实施吗？））
我假设我们需要添加每个主题active: false，当您单击分离的主题时，更改状态并检查主题的整个列表，以确定包含哪个主题并更改它。
使用主题.js
export const useTheme = () => {
// Получить системную тему пользователя
const getSystemTheme = () => window?.matchMedia('(prefers-color-scheme: dark)').matches ? 'dark' : 'light';
const [theme, setTheme] = useState(localStorage.getItem('app-theme') || getSystemTheme());
// Получить кастомные темы пользователя
const getCustomThemes = () => JSON.parse(localStorage.getItem('custom-themes')) || [];
// Добавить обьект темы в LocalStorage custom-themes
// Example: addCustomTheme({name: 'Название тема', details: [background: 'orange']})
const addCustomTheme = obj => {
if (getCustomThemes().find(t => t.name === obj.name)) return false;
localStorage.setItem(
'custom-themes',
JSON.stringify(
[
...getCustomThemes(),
{ ...obj, active: false }
]
)
);
}
useLayoutEffect(() => {
document.documentElement.setAttribute('data-theme', theme);
localStorage.setItem('theme', theme);
}, [theme]);
return { currentTheme: theme, setTheme, addCustomTheme };
}

执行时，由于数据库被锁定，程序崩溃。我用的是sqlite3。数据库被阻塞可能是什么问题以及如何解决？
例如，如果我数 0.123866/10000
import decimal
decimal.getcontext().prec = 20
a = decimal.Decimal('0.123866')
b = decimal.Decimal("10000")
print(a / b)
这段代码将给出0.0000123866
但如果我除 0.000866/10000 答案将是8.66E-8
为什么会发生这种情况，该怎么办？ （Python版本3.12）
