[英]python FPDF unicode symbols u"\u2611" or u'\U0001F5F9'
[英]Python (paramiko) - No such file or directory: u'\u012f\u0161-test.xls'
我的文件名是这个file_path=u'įš-test.xls
。
当我尝试这个:
from xlrd import open_workbook
wb = open_workbook(file_path)
我收到此错误:
File "/usr/local/lib/python2.7/dist-packages/xlrd/__init__.py", line 394, in open_workbook
f = open(filename, "rb")
IOError: [Errno 2] No such file or directory: u'\u012f\u0161-test.xls'
如果我更改为:
wb = open_workbook(file_path.encode('utf-8'))
IOError: [Errno 2] No such file or directory: '\xc4\xaf\xc5\xa1-test.xls'
注意 paramiko
可能有问题,因为使用此方法从远程目录中获取文件(如果具有unicode名称的文件是从本地目录中获取的,它也可以通过):
from contextlib import closing
import socket, os
from paramiko import SSHConfig, SSHClient, AutoAddPolicy, AuthenticationException
def check_remote_dir(self, cr, uid, ids, direct, arch_dir, gec_type, fmt, context=None):
rec = self.browse(cr, uid, ids, context=context)[0]
with closing(SSHClient()) as ssh:
ssh.set_missing_host_key_policy(AutoAddPolicy())
try:
ssh.connect(rec.host, username=rec.user, password=rec.password)
except socket.gaierror:
raise orm.except_orm(_('Error!'),
_("Name or service '%s' not known") % (rec.host))
except AuthenticationException:
raise orm.except_orm(_('Authentication Fail!'),
_("Bad username or password"))
with closing(ssh.open_sftp()) as sftp:
try:
sftp.chdir(direct)
except IOError:
raise orm.except_orm(_('Error!'),
_('Remote directory %s not found') % (direct))
try:
os.chdir(arch_dir)
except OSError:
raise orm.except_orm(_('Error!'),
_('Archive directory %s not found') % (arch_dir))
gec_obj = self.pool.get('card.gec.data')
for f in sftp.listdir():
for fmt in fmt.replace(' ', '').split(','): #removing any whitespace and then splitting in list
length = len(fmt) + 1
if f[-length:] == ".%s" % (fmt):
gec_id = gec_obj.create(cr, uid, {'name': f, 'gec_type': gec_type})
self._resolve_parse(cr, uid, gec_id, gec_obj, gec_type, f, context=context)
self.archive_file(f, None, add_dt=True, remote=True)
sftp.remove(f)
break #only need to check till first occurence
PS方法参数(例如cr, uid, ids
是特定于应用程序的,与远程文件处理并没有真正的关系,因此您可以忽略这些参数
更新我在日志中注意到了这一点:
2015-02-03 10:23:48,143 10430 INFO amb_test paramiko.transport.sftp: [chan 1] Opened sftp connection (server version 3)
is-test.xls
2015-02-03 10:23:48,162 10430 INFO amb_test paramiko.transport.sftp: [chan 1] sftp session closed.
发生这种情况,然后出现该错误。 使用文件之前可能会关闭会话吗?
Update2似乎sftp.listdir()
。 当我尝试从中使用文件名时,例如使用标准open
,它会出错,因为没有文件,因为我猜它只检查本地目录(我不知道它以前是如何工作的..)。 如果我尝试使用sftp.open()
打开,那么它将起作用。
如何使用远程路径在本地服务器中打开它?
远程文件路径似乎出了点问题。 当我得到一个远程路径并尝试直接从该路径打开时,它将看不到它,并且会抛出一个错误,即找不到该文件。
因此,我重写了方法,以不同方式处理远程文件。 现在,它只下载并在本地打开它,而不是远程打开(并且仅在解析后将其保存在本地)。
如果有更好的方法,请随时将其发布为答案。 所以在这里,我的新方法解决了我的问题:
