server.py无法启动，路径中的unicode字符有问题。

Question

好吧，我想用python运行一个服务器。当我试图启动服务器时，我得到了这个。

D:\Users\DearJohn28\Downloads\prgm>python3 server.py
INFO:engineio.server:Server initialized for threading.
Traceback (most recent call last):
  File "server.py", line 63, in <module>
    app.initialize()
  File "D:\Users\DearJohn28\Downloads\prgm\app.py", line 21, in initialize
    settings = initSettings()
  File "D:\Users\DearJohn28\Downloads\prgm\prgm\app\settings.py", line 30, in initSettings
    makedirs(settings['downloadLocation'], exist_ok=True)
  File "D:\Python\Python37\lib\os.py", line 213, in makedirs
    makedirs(head, exist_ok=exist_ok)
  File "D:\Python\Python37\lib\os.py", line 213, in makedirs
    makedirs(head, exist_ok=exist_ok)
  File "D:\Python\Python37\lib\os.py", line 213, in makedirs
    makedirs(head, exist_ok=exist_ok)
  File "D:\Python\Python37\lib\os.py", line 223, in makedirs
    mkdir(name, mode)
OSError: [WinError 123] The filename, directory name, or volume label syntax is incorrect: '\u202aD:'    

我以前用过一次，所以我不知道发生了什么。据我所知，当它建立一个目录时，有一个unicode字符触发了一个OSError。

我想说的是，我对python不太熟练，但我很好地遵循了方向。

这就是makedirs()的作用。

#!/usr/bin/env python3
import json
import os.path as path
from os import makedirs

import prgm.utils.localpaths as localpaths

settings = {}
defaultSettings = {}


def initSettings():
    global settings
    global defaultSettings
    currentFolder = path.abspath(path.dirname(__file__))
    configFolder = localpaths.getConfigFolder()
    makedirs(configFolder, exist_ok=True)
    with open(path.join(currentFolder, 'default.json'), 'r') as d:
        defaultSettings = json.load(d)
        defaultSettings['downloadLocation'] = path.join(localpaths.getHomeFolder(), 'mymedia')
    if not path.isfile(path.join(configFolder, 'config.json')):
        with open(path.join(configFolder, 'config.json'), 'w') as f:
            json.dump(defaultSettings, f, indent=2)
    with open(path.join(configFolder, 'config.json'), 'r') as configFile:
        settings = json.load(configFile)
    settingsCheck()
    if settings['downloadLocation'] == "":
        settings['downloadLocation'] = path.join(localpaths.getHomeFolder(), 'mymedia')
        saveSettings(settings)
    makedirs(settings['downloadLocation'], exist_ok=True)
    return settings


def getSettings():
    global settings
    return settings


def getDefaultSettings():
    global defaultSettings
    return defaultSettings


def saveSettings(newSettings):
    global settings
    settings = newSettings
    with open(path.join(localpaths.getConfigFolder(), 'config.json'), 'w') as configFile:
        json.dump(settings, configFile, indent=2)
    return True


def settingsCheck():
    global settings
    global defaultSettings
    changes = 0
    for x in defaultSettings:
        if not x in settings or type(settings[x]) != type(defaultSettings[x]):
            settings[x] = defaultSettings[x]
            changes += 1
    for x in defaultSettings['tags']:
        if not x in settings['tags'] or type(settings['tags'][x]) != type(defaultSettings['tags'][x]):
            settings['tags'][x] = defaultSettings['tags'][x]
            changes += 1
    if changes > 0:
        saveSettings(settings)

prgm.utils.localpaths

#!/usr/bin/env python3
import os.path as path
import sys
from os import getenv

userdata = ""
homedata = path.expanduser("~")

if getenv("APPDATA"):
    userdata = getenv("APPDATA") + path.sep + "mymedia" + path.sep
elif sys.platform.startswith('darwin'):
    userdata = homedata + '/Library/Application Support/mymedia/'
elif getenv("XDG_CONFIG_HOME"):
    userdata = getenv("XDG_CONFIG_HOME") + '/mymedia/';
else:
    userdata = homedata + '/.config/mymedia/';


def getHomeFolder():
    return homedata


def getConfigFolder():
    return userdata

我怎么去解决这个问题？

这个调用 makedirs(settings['downloadLocation'], exist_ok=True) 你需要从调用中的设置中提取 "downloadLocation"，通过运行 settings['downloadLocation'] 从你的字典中提取值。
