Python小技巧

引包方式

在引包 部署时 总会出现路径问题，包括execjs的路径

万能导入引包

import sys
import os

sys.path.append(os.path.join(os.path.dirname(__file__), ".."))

或者

import sys
import os

script_path = os.path.abspath(os.path.dirname(__file__) + "./..")
if script_path not in sys.path:
  sys.path.append(script_path)

万能路径

from pathlib import Path
# 获取当前工作目录
current_path = Path.cwd()
file_path = current_path / "aaaa" / "bbb.js"

提取json

类似于下文这样的JSON提取出JSON

VaptchaJsonp1756106013582({“code”: “0103”,”data”: {“knock”:”1756107661vbymKE2e12d”,”cdn_servers”:[“static-cn.vaptcha.net”],”css_version”:”2.9.12”,”js_path”:”verify.2.2.4.js”,”help”:true,”is_vip”:-1,”guideVersion”:”3.1.0”,”sdk_ver”:”vaptcha-sdk.1.2.35.669f69e6.js”,”net_way”:-1,”node”:”CN”,”server”:”https://0.vaptcha.com/verify"},"msg":""})

extract_json = lambda s: json.loads(s[s.find('{'):s.rfind('}') + 1])

添加代理

proxies = lambda authKey="xxx", password="xxx", proxyAddr="xxxx:xxx": {
            "http": f"http://{authKey}:{password}@{proxyAddr}",
            "https": f"http://{authKey}:{password}@{proxyAddr}",
        }
