############################## QUICK SETUP start ##############################
############################## 快速设置 开始 ###################################
# Setting SCRAPYDWEB_BIND to '0.0.0.0' or IP-OF-THE-CURRENT-HOST would make
# ScrapydWeb server visible externally; Otherwise, set it to '127.0.0.1'.
# The default is '0.0.0.0'.
SCRAPYDWEB_BIND = '0.0.0.0'
# Accept connections on the specified port, the default is 5000.
SCRAPYDWEB_PORT = 5000

# The default is False, set it to True to enable basic auth for the web UI.
ENABLE_AUTH = False
# In order to enable basic auth, both USERNAME and PASSWORD should be non-empty strings.
USERNAME = ''
PASSWORD = ''


# Make sure that [Scrapyd](https://github.com/scrapy/scrapyd) has been installed
# and started on all of your hosts.
# Note that for remote access, you have to manually set 'bind_address = 0.0.0.0'
# in the configuration file of Scrapyd and restart Scrapyd to make it visible externally.
# Check out 'https://scrapyd.readthedocs.io/en/latest/config.html#example-configuration-file' for more info.
# ------------------------------ Chinese --------------------------------------
# 请先确保所有主机都已经安装和启动 [Scrapyd](https://github.com/scrapy/scrapyd)。
# 如需远程访问 Scrapyd，则需在 Scrapyd 配置文件中设置 'bind_address = 0.0.0.0'，然后重启 Scrapyd。
# 详见 https://scrapyd.readthedocs.io/en/latest/config.html#example-configuration-file

# - the string format: username:password@ip:port#group
#   - The default port would be 6800 if not provided,
#   - Both basic auth and group are optional.
#   - e.g. '127.0.0.1:6800' or 'username:password@localhost:6801#group'
# - the tuple format: (username, password, ip, port, group)
#   - When the username, password, or group is too complicated (e.g. contains ':@#'),
#   - or if ScrapydWeb fails to parse the string format passed in,
#   - it's recommended to pass in a tuple of 5 elements.
#   - e.g. ('', '', '127.0.0.1', '6800', '') or ('username', 'password', 'localhost', '6801', 'group')

# It's recommended to update the three options below
# if both ScrapydWeb and one of your Scrapyd servers run on the same machine.
# ------------------------------ Chinese --------------------------------------
# 假如 ScrapydWeb 和某个 Scrapyd 运行于同一台主机，建议更新如下三个设置项。

# If both ScrapydWeb and one of your Scrapyd servers run on the same machine,
# ScrapydWeb would try to directly read Scrapy logfiles from disk, instead of making a request
# to the Scrapyd server.
# e.g. '127.0.0.1:6800' or 'localhost:6801', do not forget the port number.

# Check out https://scrapyd.readthedocs.io/en/stable/config.html#logs-dir for more info.
# e.g. 'C:/Users/username/logs' or '/home/username/logs'

# 1. Visit https://api.slack.com/apps and press the "Create New App" button.
# 2. Enter your App Name (e.g. myapp)and select one of your Slack Workspaces, the press "Create App".
# 3. Click the "OAuth & Permissions" menu in the sidebar on the left side of the page.
# 4. Scroll down the page and find out "Select Permission Scopes" in the "Scopes" section
# 5. Enter "send" and select "Send messages as <your-app-name>", then press "Save Changes"
# 6. Scroll up the page and press "Install App to Workspace", then press "Install"
# 7. Copy the "OAuth Access Token", e.g. xoxp-123-456-789-abcde
# See https://api.slack.com/apps for more info

# How to create a telegram bot:
# 1. Visit https://telegram.me/botfather to start a conversation with Telegram's bot that creates other bots.
# 2. Send the /newbot command to create a new bot in a chat with BotFather.
# 3. Follow the instructions to set up name and username (e.g. my_bot) for your bot.
# 4. You would get a token (e.g. 123:abcde) after step 3.
# 5. Visit telegram.me/<bot_username> (e.g. telegram.me/my_bot) and say hi to your bot to initiate a conversation.
# 6. Visit https://api.telegram.org/bot<token-in-setp-4>/getUpdates to get the chat_id.

# - LOG_XXX_TRIGGER_STOP (optional):
#   - The default is False, set it to True to stop current job automatically when reaching the LOG_XXX_THRESHOLD.
#   - The SIGTERM signal would be sent only one time to shut down the crawler gracefully.
#   - In order to avoid an UNCLEAN shutdown, the 'STOP' action would be executed one time at most
#   - if none of the 'FORCESTOP' triggers is enabled, no matter how many 'STOP' triggers are enabled.
# - LOG_XXX_TRIGGER_FORCESTOP (optional):
#   - The default is False, set it to True to FORCESTOP current job automatically when reaching the LOG_XXX_THRESHOLD.
#   - The SIGTERM signal would be sent twice resulting in an UNCLEAN shutdown, without the Scrapy stats dumped!
#   - The 'FORCESTOP' action would be executed if both of the 'STOP' and 'FORCESTOP' triggers are enabled.

# Note that the 'STOP' action and the 'FORCESTOP' action would still be executed even when the current time
# is NOT within the ALERT_WORKING_DAYS and the ALERT_WORKING_HOURS, though no alert would be sent.
