Question

我尝试编写OO Python代码的方式与我在Java中学习的方式相同，这可能是我向南走的地方。我有一个主要的脚本和一个别人写的我改编的课程。我在主脚本中调用了类，但是我使用的每种技术[类名]都不可调用。

以下是最近的尝试。这是主要的脚本。为了安全起见，已删除变量directoryPairs。

import yaml
import pysftp
import FingerprintKey

with open('config/config.yaml') as settings:
    cfg = yaml.load(settings)

host = cfg['host']
username = cfg['username']
password = cfg['password']
serverkey = cfg['fingerPrint']

x = FingerprintKey(serverkey)

options = pysftp.CnOpts()
options.hostkeys.clear()
options.hostkeys.add('www.example.com', u'ecdsa-sha2-nistp384', x)

with pysftp.Connection(host, username=username, password=password, cnopts=options) as sftp:
    #for source, destination in directoryPairs.items():
        #sftp.get_d(source, destination, preserve_mtime=True)
        #if sftp.exists(source):
            #files = sftp.listdir(source)
            #for f in files:
                #sftp.remove(os.path.join(source, f))
    sftp.close()

以下是FingerprintKey.py类

import hashlib as hl


def trim_fingerprint(fingerprint):
    if fingerprint.startswith('ecdsa-sha2-nistp384 384 '):
        return fingerprint[len('ecdsa-sha2-nistp384 384 '):]
    return fingerprint


def clean_fingerprint(fingerprint):
    return trim_fingerprint(fingerprint).replace(':', '')


class FingerprintKey:

    def __init__(self, fingerprint):
        self.fingerprint = clean_fingerprint(fingerprint)

    def compare(self, other):
        if callable(getattr(other, "get_fingerprint", None)):
            return other.get_fingerprint() == self.fingerprint
        elif clean_fingerprint(other) == self.get_fingerprint():
            return True
        elif hl.md5(other).digest().encode('hex') == self.fingerprint:
            return True
        else:
            return False

    def __cmp__(self, other):
        return self.compare(other)

    def __contains__(self, other):
        return self.compare(other)

    def __eq__(self, other):
        return self.compare(other)

    def __ne__(self, other):
        return not self.compare(other)

    def get_fingerprint(self):
        return self.fingerprint

    def get_name(self):
        return u'ecdsa-sha2-nistp384'

    def asbytes(self):
         # Note: This returns itself.
         #   That way when comparisons are done to asbytes return value,
         #   this class can handle the comparison.
        return self

这两个文件都在同一目录中。

感谢mkrieger1我对代码进行了以下添加，但它确实有效。

我将类文件重命名为AuthOnFingerPrint

$('#companiesDDL  option[value="/Writeup/Writeups?symbol=tsla&;status=A"]').prop("selected", true);

为什么我的Python类不可调用？
