比特币 RPC 连接

Question

我正在尝试使用 python3 将比特币交易插入 MongoDB。以下是我的代码：

import pymongo
import sys
import json
import time
from bitcoinrpc.authproxy import AuthServiceProxy, JSONRPCException

rpc_connection = AuthServiceProxy("http://xxx:xxx@ipaddress:port")

def getTransaction():
    addresses = []
    txa = []
    commands = [ [ "getblockhash", height] for height in range(400000,550000) ]
    #print(commands)

    block_hashes = rpc_connection.batch_(commands)
    blocks = rpc_connection.batch_([ [ "getblock", h ] for h in block_hashes ])
    print(blocks)
    for txpre in blocks:
        #print(txpre)
        for txs in txpre["tx"]:
            txa.append(txs)
    trans = conTransaction(txa)
    return trans

我收到以下错误：

Traceback (most recent call last):
  File "/usr/lib/python3.6/threading.py", line 916, in _bootstrap_inner
    self.run()
  File "/usr/lib/python3.6/threading.py", line 864, in run

    self.sock.sendall(data)
BrokenPipeError: [Errno 32] Broken pipe

我检查了 bitcoind rpc 连接，它已连接。
block_hashes = rpc_connection.batch_(commands) 此代码行出错。谁能告诉我怎么了？

我找到了解决方案。在对比特币配置文件进行更改后，我只是减少了要插入的记录范围。 RPC 服务器无法一次处理大量数据。否则会出现服务器宕机问题，连接失败。一次最多插入 100 条记录或更少。还有一件事，通过下面给出的停止和启动命令继续重启 bitcoind RPC 服务器：

sudo killall bitcoind
bitcoind -daemon -rpcuser=xxx -rpcpassword=xxx -txindex -rpcallowip=youripaddress
