去除 \ufeff——访问网址或读取文件莫名其妙无法读取错误——raise InvalidSchema("No connection adapters were found for '%s'" % url) requests.exceptions.InvalidSchema: No connection adapters were found for

raise InvalidSchema("No connection adapters were found for ‘%s‘" % url)
requests.exceptions.InvalidSchema: No connection adapters were found for

访问的网址明明没有问题，却报以上的错误，还以为requests库出问题了呢。

细心排查一下你会发现网址前面可能会有\ufeff这个字符，这就是UFT-8编码导致的。

把 UTF-8 编码 改成 UTF-8-sig即可。
