在python3.5中使用proxybroker会抛出编码错误

Question

我正在尝试使用proxybroker 为某些国家/地区生成具有活动代理的文件。我总是在尝试获取代理时遇到同样的错误。该错误似乎是 proxbroker 使用的数据包中的编码/解码错误。但我怀疑可能有更好的方法来使用代理代理。

这是导致问题的代码：

def gather_proxies(countries):
"""
This method uses the proxybroker package to asynchronously get two new proxies per specified country
and returns the proxies as a list of country and proxy.

:param countries: The ISO style country codes to fetch proxies for. Countries is a list of two letter strings.
:return: A list of proxies that are themself a list with  two paramters[Location, proxy address].
"""
proxy_list = []
types = ['HTTP']
for country in countries:
    loop = asyncio.get_event_loop()

    proxies = asyncio.Queue(loop=loop)
    broker = Broker(proxies, loop=loop,)

    loop.run_until_complete(broker.find(limit=2, countries=country, types=types))

    while True:
        proxy = proxies.get_nowait()
        if proxy is None:
            break
        print(str(proxy))
        proxy_list.append([country, proxy.host + ":" + str(proxy.port)])
return proxy_list

以及错误信息：

问题似乎出在代理代理或 aiohttp 包中。但由于它应该是一个经过测试的包，问题可能是我的代码。

谁能看到我做错了什么，或者有人对代理代理的使用有什么建议吗？

Answer 1

问题出在resp.text() 电话中。 它检索 html 页面作为文本。 aiohttp 尝试使用 chardet 库确定正确的编码，但对于格式错误的页面，这是不可能的。

我认为resp.text() 应该替换为resp.read() 以获取bytes 的页面而不解码为str。
