EC2服务器中ccxt.load_markets()运行失败求助

问题详情 #

在EC2服务器运行CCXT的load_markets()函数时返回451错误，本地PC环境运行相同代码则正常。相关环境信息：

• Python版本：3.7.15
• CCXT版本：2.2.95
• 运行代码：

import ccxt
import time

b= ccxt.binance()

print(b.milliseconds())
print(b.nonce())
print(b.load_markets())

在处理上述异常期间，又发生了新的异常：

}

问题原因 #

Binance的地域访问限制策略拦截了EC2服务器的IP地址，导致无法访问其API接口。本地环境IP不在限制列表中，因此可以正常运行。

解决方案 #

• 配置代理：在EC2服务器上设置合规的代理服务，将API请求转发到Binance允许访问的地区IP。
• 更换EC2区域：选择Binance未限制的AWS区域（如新加坡、东京等）重新创建EC2实例。
• 账号合规验证：确认Binance账号注册地区与服务器所在地区是否匹配，若存在不符可联系Binance客服核实权限。
