Replit运行requests代码遇requests.exceptions.SSLError问题求助

问题概述 #

• 一周前可正常运行的Python requests代码，现在在Replit上执行出现SSL错误
• 目标URL在浏览器中能正常访问，已尝试网络常规方案（含Stack Overflow相关解法）但无效

原代码 #

import requests

url = ‘https://iss.moex.com/iss/statistics/engines/stock/markets/index/analytics.csv’
print(url)

r = requests.get(url).text
print (r)

报错信息（翻译后） #

Traceback (most recent call last):… requests.exceptions.SSLError:
HTTPSConnectionPool(host='iss.moex.com', port=443): Max retries exceeded with url:
/iss/statistics/engines/stock/markets/index/analytics.csv (Caused by SSLError(SSLEOFError(8, '[SSL: UNEXPECTED_EOF_WHILE_READING] EOF occurred in violation of protocol (_ssl.c:1007)')))

解决方案 #

1. 修正代码中的中文引号 #

原代码使用了中文全角引号，会导致URL解析异常，替换为英文半角引号即可：

import requests

url = 'https://iss.moex.com/iss/statistics/engines/stock/markets/index/analytics.csv'
print(url)

r = requests.get(url).text
print(r)

2. 强制指定兼容的TLS版本 #

部分服务器会调整TLS支持策略，Replit环境默认TLS版本可能不匹配。通过自定义适配器强制使用TLSv1.2：

import requests
import ssl
from requests.adapters import HTTPAdapter
from urllib3.poolmanager import PoolManager
from urllib3.util import ssl_

class TLSAdapter(HTTPAdapter):
    def init_poolmanager(self, connections, maxsize, block=False):
        # 创建指定TLS版本的SSL上下文
        ctx = ssl_.create_urllib3_context(
            ssl_version=ssl.PROTOCOL_TLSv1_2,
            cert_reqs=ssl.CERT_REQUIRED,
            options=ssl.OP_NO_TLSv1 | ssl.OP_NO_TLSv1_1
        )
        self.poolmanager = PoolManager(
            num_pools=connections,
            maxsize=maxsize,
            block=block,
            ssl_context=ctx
        )

url = 'https://iss.moex.com/iss/statistics/engines/stock/markets/index/analytics.csv'
session = requests.Session()
# 给HTTPS请求挂载自定义适配器
session.mount('https://', TLSAdapter())

try:
    response = session.get(url).text
    print(response)
except Exception as e:
    print(f"错误详情: {str(e)}")

3. 临时跳过SSL验证（仅用于测试） #

若上述方法无效，可临时关闭SSL验证排查问题（生产环境禁止使用，存在安全风险）：

import requests
import urllib3

# 关闭不安全请求警告
urllib3.disable_warnings(urllib3.exceptions.InsecureRequestWarning)

url = 'https://iss.moex.com/iss/statistics/engines/stock/markets/index/analytics.csv'
print(url)

response = requests.get(url, verify=False).text
print(response)
