本地用Python requests访问api.rugcheck.xyz遇SSL版本错误

问题场景 #

本地使用Python requests模块请求api.rugcheck.xyz时触发SSL版本错误，本地访问其他网站无异常；部署在Streamlit的应用请求该API正常，确认问题仅存在于本地机器与目标站点之间。

测试代码 #

import requests

response = requests.get("https://api.rugcheck.xyz/v1/stats/new_tokens")
data = response.json()
print(data)

已尝试操作 #

• 更新urllib3至最新版本
• 确认本地OpenSSL版本为3.0.15
• 搜索相关错误未找到匹配解决方案

解决办法 #

关闭ISP高级安全设置中的URL屏蔽功能后，请求恢复正常。

错误原因说明 #

ISP的URL屏蔽机制拦截请求时，会向目标端口（443）返回非HTTPS协议的响应（比如拦截提示页面的HTTP内容）。此时客户端发起SSL握手，收到的却是不符合TLS协议版本的数据，因此触发WRONG_VERSION_NUMBER错误。
