先后用了python3.7和python2.7跑，都跑不通

是不是网站又更新了反爬策略？ 报错如下： 2018-12-26 17:13:54 [scrapy.utils.log] INFO: Scrapy 1.5.1 started (bot: wenshu) 2018-12-26 17:13:54 [scrapy.utils.log] INFO: Versions: lxml 4.2.5.0, libxml2 2.9.8, cssselect

https://github.com/zc3945/caipanwenshu/tree/master/wenshu/wenshu/utils 请先尝试运行这里的docid.py 和vl5x.py 。如果报错，根据错误提示再解决

[CoderRobin1992]

vl5x.py运行正常，docid.py运行报错如下： Traceback (most recent call last): File "docid.py", line 115, in <module> key = getkey(RunEval).encode('utf-8') File "docid.py", line 104, in getkey js_str = unzip(str1).replace('_[_][_](', 'return ')[:-4] File "docid.py", line 100, in unzip return btou(get_js(fromBase64(str1))) File "docid.py", line 94, in get_js eval_js = execjs.compile(js_data) File "/usr/lib/python2.7/site-packages/execjs/__init__.py", line 61, in compile return get().compile(source, cwd) File "/usr/lib/python2.7/site-packages/execjs/_runtimes.py", line 21, in get return get_from_environment() or _find_available_runtime() File "/usr/lib/python2.7/site-packages/execjs/_runtimes.py", line 49, in _find_available_runtime raise exceptions.RuntimeUnavailableError("Could not find an available JavaScript runtime.") execjs._exceptions.RuntimeUnavailableError: Could not find an available JavaScript runtime.

我用selenium爬取，从列表页进入，会更简单一些，不过效率相差太大了。。。

想请教下怎么跳过网站的IP检测，爬取部分完成了，但是现阶段已经触发了检测机制，跳出验证码，使用过一家的IP代理也不行，甚至提醒记录了mac address，无效用户
