5 OK链如何监听链上数据

tx_filter = w3.eth.filter('pending')
block_filter = w3.eth.filter('latest')
Traceback (most recent call last):
  File "sniper.py", line 100, in <module>
    startTx()
  File "sniper.py", line 79, in startTx
    loop.run_until_complete(asyncio.gather(log_loop(tx_filter)))
  File "/Users/zhong/opt/anaconda3/lib/python3.8/asyncio/base_events.py", line 616, in run_until_complete
    return future.result()

    for event in event_filter.get_new_entries():
  File "/Users/zhong/opt/anaconda3/lib/python3.8/site-packages/web3/_utils/filters.py", line 160, in get_new_entries
    log_entries = self._filter_valid_entries(self.eth_module.get_filter_changes(self.filter_id))
  File "/Users/zhong/opt/anaconda3/lib/python3.8/site-packages/web3/module.py", line 57, in caller
    result = w3.manager.request_blocking(method_str,
  File "/Users/zhong/opt/anaconda3/lib/python3.8/site-packages/web3/manager.py", line 198, in request_blocking
    return self.formatted_response(response,
  File "/Users/zhong/opt/anaconda3/lib/python3.8/site-packages/web3/manager.py", line 171, in formatted_response
    raise ValueError(response["error"])
ValueError: {'code': -32000, 'message': 'the method is not allowed'}

监听提示这个,有没有什么办法解决,或者ok链本身就不是这样监听的。 希望有大佬看看


async function startConnection() {
provider.on('pending', async (txHash) => {
setTimeout(async () => {
try {
let tx = await provider.getTransaction(txHash);
console.log(tx)
} catch (err) {
console.error(`${txHash} ${err}`)
}
})
});
};

用Js可以正常获取



const provider = new ethers.providers.WebSocketProvider('wss://exchainws.okex.org:8443')

节点需要支持 websocket , 如果节点一样,而用 JS 可以获取, 那么应该是你 Python 代码的问题。
