用test_proxy测试，成功率不是很高

r = session.get('http://127.0.0.1:3289/count')
r.json()
{'count': '4200'}
抓到了特别多的https,是不是这个影响的呢？

Reproduce the reported checks against /count and /get/10 or /get/200 using https://zhihu.com, and compare the returned proxy protocols with the success and failure counts. Read the proxy-fetching and validation entry points to determine whether the low success rate is caused by HTTPS handling. Done means the cause is documented and the affected behavior has a verified fix or an explicit limitation.
