* 1、设置scheduler.py中dev模式的flask run，不进行启动时的自动重新加载reload

* 1、修改PROXY_SCORE_MAX，PROXY_SCORE_MIN，PROXY_SCORE_INIT三项配置，为可环境变量配置
2、添加可环境变量配置项TEST_DONT_SET_MAX_SCORE，允许设置当tester检测到某个proxy可用时，只是保持原score，而不将其score设置成max。

* 增加获取proxy接口的认证header, API-KEY。可配置，默认不需要

- utils/proxy: fix ValueError on multi-colon proxy strings in the str branch of convert_proxy_or_proxies, which made /random return 500 (Python3WebSpider#218)

- scheduler: guard None process handles in finally so ENABLE_*=false no longer raises AttributeError (Python3WebSpider#62)

- tester: replace deprecated get_event_loop()/asyncio.wait() with a fresh loop + asyncio.gather to fix 'Passing coroutines is forbidden' on Python 3.10+ (Python3WebSpider#191, Python3WebSpider#201)

- tester: reuse one aiohttp session with a bounded connector instead of one per proxy, reducing memory growth and fd exhaustion (Python3WebSpider#119, Python3WebSpider#155)

- tester: catch ClientResponseError/ContentTypeError + return_exceptions so bad httpbin responses no longer raise 'Task exception was never retrieved' (Python3WebSpider#208)

…#230)

- requirements: move to Flask 2.x and drop the ancient itsdangerous==0.24 / MarkupSafe<2.1 pins that blocked installs on Python 3.10+; bump redis to 4/5, aiohttp>=3.9, lxml<6, gevent<25; add explicit Werkzeug<3 bound

- Dockerfile: base image python:3.7-alpine (EOL) -> python:3.11-slim so gevent/lxml/aiohttp install from wheels instead of compiling under musl, fixing common build failures and enabling arm64 (e.g. Raspberry Pi)

- server: validate the key query parameter against a strict charset (letters, digits, _ : -, max 64) so the API cannot be used to probe arbitrary redis keys; invalid keys return 400

- server: /count without a key returned a bare int which Flask rejects; always return a string

- README: document API_KEY and add a security note about exposing the pool publicly without authentication

…thon3WebSpider#177) (Python3WebSpider#233)

* feat: support fetching multiple proxies via /random?count=N

- redis: add RedisClient.randoms(count, ...) which prefers max-score proxies and falls back to rank, returning a de-duplicated random sample

- server: /random accepts a count parameter and returns N random proxies (one per line); count<=1 keeps the original single-proxy behavior; works with key too

- README: document the new count parameter

Closes Python3WebSpider#194

* feat: filter proxies by country via ?area=CN on /random and /all

- utils/geo: add get_country_iso() backed by the bundled GeoLite2 db (previously an unused dependency); fails safe to None if unavailable

- server: /random and /all accept an area parameter (country iso code) to return only proxies from that country; combines with count and key

- README: document the area parameter

Closes Python3WebSpider#84, Closes Python3WebSpider#177

…MOUS_URL (Python3WebSpider#234)

- setting: add TEST_ANONYMOUS_URL (default https://httpbin.org/ip)

- tester: use TEST_ANONYMOUS_URL instead of the hardcoded httpbin.org endpoint so users can self-host httpbin and avoid public rate limits

- README: document TEST_ANONYMOUS_URL and TEST_ANONYMOUS

Closes Python3WebSpider#109
