SSH/SCP通過Paramiko與字符串中的鍵

我有一個偉大的Paramiko Python腳本通過SCP協議傳輸文件。但我的需求是一個單獨的文件（script.py），沒有任何其他文件依賴關係，所以我不想爲我的SSH私鑰有一個外部文件。SSH/SCP通過Paramiko與字符串中的鍵

我想要做的是將私鑰嵌入到字符串變量中，並使用此變量作爲腳本連接所需的文件。我試圖與StringIO庫，但它似乎並不工作：

hostname = '1.1.1.1' # remote hostname where SSH server is running 
port = 22 
username = 'user' 
password = 'pswd' 

dir_local='/home/paramikouser/local_data' 
dir_remote = "remote_machine_folder/subfolder" 
glob_pattern='*.*' 

import os 
import glob 
import paramiko 
import md5 
import StringIO 

private_key = StringIO.StringIO('-----BEGIN RSA PRIVATE KEY-----\n-----END RSA PRIVATE KEY-----') 

def agent_auth(transport, username): 
    """ 
    Attempt to authenticate to the given transport using any of the private 
    keys available from an SSH agent or from a local private RSA key file (assumes no pass phrase). 
    """ 
    try: 
     ki = paramiko.RSAKey.from_private_key_file(private_key) 
    except Exception, e: 
     print 'Failed loading' % (private_key, e) 

    agent = paramiko.Agent() 
    agent_keys = agent.get_keys() + (ki,) 
    if len(agent_keys) == 0: 
     return 

    for key in agent_keys: 
     print 'Trying ssh-agent key %s' % key.get_fingerprint().encode('hex'), 
     try: 
      transport.auth_publickey(username, key) 
      print '... success!' 
      return 
     except paramiko.SSHException, e: 
      print '... failed!', e 

# get host key, if we know one 
hostkeytype = None 
hostkey = None 
files_copied = 0 
try: 
    host_keys = paramiko.util.load_host_keys(os.path.expanduser('~/.ssh/known_hosts')) 
except IOError: 
    try: 
     # try ~/ssh/ too, e.g. on windows 
     host_keys = paramiko.util.load_host_keys(os.path.expanduser('~/ssh/known_hosts')) 
    except IOError: 
     print '*** Unable to open host keys file' 
     host_keys = {} 

if host_keys.has_key(hostname): 
    hostkeytype = host_keys[hostname].keys()[0] 
    hostkey = host_keys[hostname][hostkeytype] 
    print 'Using host key of type %s' % hostkeytype 

# now, connect and use paramiko Transport to negotiate SSH2 across the connection 
try: 
    print 'Establishing SSH connection to:', hostname, port, '...' 
    t = paramiko.Transport((hostname, port)) 
    t.start_client() 

    agent_auth(t, username) 

    if not t.is_authenticated(): 
     print 'RSA key auth failed! Trying password login...' 
     t.connect(username=username, password=password, hostkey=hostkey) 
    else: 
     sftp = t.open_session() 
    sftp = paramiko.SFTPClient.from_transport(t) 
# dirlist on remote host 
# dirlist = sftp.listdir('.') 
# print "Dirlist:", dirlist

如何使用這個字符串作爲關鍵？

把密鑰寫入tmp文件怎麼樣？ – pynexj

我希望這不是您在問題中發佈的真正關鍵。 –

這是一個沒有任何權利的客人鑰匙，無論如何，你沒有服務器的IP沒有？我編輯了這個問題，如果這是更好的 –

使用RSAKey.from_private_key：

ki = paramiko.RSAKey.from_private_key(private_key)

見How do use paramiko.RSAKey.from_private_key()?

對上述問題的回答顯示的代碼爲Python 3

在Python 2.7，這個工程：

請將完整的代碼附加到您的問題中。 –

完成了。無論如何感謝您的幫助 –

您的代碼適合我。你使用的是什麼版本的Python/Paramiko？ –
