最近收到一些插件反馈，对Calibre桌面版豆瓣插件进行一些简单升级
以前安装文档：https://fugary.com/?p=264
Calibre电子书管理软件：https://calibre-ebook.com/download
calibre-douban是Calibre电子书软件的豆瓣元数据插件
下载地址
项目地址：https://github.com/fugary/calibre-douban
下载地址：https://github.com/fugary/calibre-douban/releases/latest/download/NewDouban.zip
代理下载：https://ghproxy.com/https://github.com/fugary/calibre-douban/releases/latest/download/NewDouban.zip
从release页面下载zip包，然后再calibre中安装为插件即可。
升级内容
删除了一些无用代码，另外增加功能：
- 增加
gzip支持，有可能提升一点速度 - 增加随机毫秒延迟，减少被403的几率
- 增加
Cookie输入框，可以填入浏览器登录后的Cookie，减少403
配置随机延迟
默认已开启随机延迟，也就是在并发请求详情数据的时候随机sleep一定的毫秒数，可以关闭：
参考代码
def random_sleep(self, log):
random_sec = random.random() / 10
log.info("Random sleep time {}s".format(random_sec))
time.sleep(random_sec)Cookie配置
有时候可能我们的IP已经被拦了，这时可以自己登录豆瓣网站，然后把Cookie复制出来填进插件配置中。
IP被拦的错误如下：
有异常请求从你的 IP 发出，请 登录 使用豆瓣
用Chrome或者Edge浏览器打开https://www.douban.com，点击【登录】进入登录页面，登录成功之后，按F12打开开发者工具：
从Network，找到Doc类型，随便点击一个豆瓣的网址，进入Headers，找到Request Headers里面的Cookie字段，如图：
如果是中文版：
从网络，找到文档类型，随便点击一个豆瓣的网址，进入标头，找到请求标头里面的Cookie字段，如图：
找到Cookie:后面的部分，复制后面的内容，不包含Cookie:。
到Calibre插件配置页面填入Cookie：
然后就可以用用户的身份查询，一般是可以解决403问题。
常见错误
如果又遇到查询失败，可能是这个错误
…你访问豆瓣的方式有点像机器人程序。为了保护用户的数据，请向我们证明你是人类:
因为使用了Cookie，可以在浏览器中自己点击证明一下，再在calibre中重新查询即可。
赞！估计昨天对100多本书提取了豆瓣的信息，结果被BAN了，今天使用了博主介绍的方法，果然解决了！赞！
我用cookie搜不到，不用cookie反而搜到了。然后搜了几本书就报403错误，但是按教程输入cookie不起作用。报错：ValueError: Invalid header value b…。也没提示机器人问题
有报错

Failed to download metadata for 大学生实用口才学
有时不需要下载封面，好像不能单独下载元数据？
牛逼，可用的，感谢
感谢博主~收藏了~
大佬，自定义插件只有元数据段的选择和 include subtitle，下不了怎么办😱
最好提供下软件版本，错误日志等，可以到GitHub提交issue
及空间的calibre docker怎么设置呢?大佬
你好，请问，我WIN11,在Calibre桌面版安装插件后，菜单栏上看不到这个插件，但插件自定义那显示已经安装了这个插件，这会是什么原因呢？
已经找到了，原来在元数据下载那里体现的。谢谢啦
大佬，是不是最近豆瓣插件不能用了，新书导入搜不到，旧书也搜不出来元数据了

昨天还用过，应该没问题吧，有isbn号优先用isbn号，可以尝试删除isbn再试试看
彻底删除后重装软件即可解决问题，感谢大佬~

报这个错，不知道什么原因，能请博主看看嘛？
改改名字再搜，名字乱了也搜不到数据
ok，下好了，谢谢博主
Calibre桌面版：5.1.0
近期更新图书也较少，刚发现插件2023年7月有更新，尝试了https://github.com/fugary/calibre-douban，v2.0.1版本的插件，下载封面时有如下日志报错信息。配置Cookie时也遇到了上文所述的机器人验证，已通过，但Cookie内容和图示有所差别。由于看不懂，就把Cookie双击复制到插件的文本框内。看报错信息成功找到了正确的元数据网址，但似乎因为这个xpath属性导致报错。
我是在摸索群晖存储电子书的过程中发现了宝藏博主，感谢分享！向您学习！

我本来是手动维护的，后来突然想到会不会有插件，一搜还真有，非常好用，感谢您
感谢感谢^^
大大，豆瓣源书籍信息可以找到并添加，但是到书封面那里无法加载，看了日志显示403

最新版应该已经修复此问题
calibre升级到最新6.22，然后插件卸载重装可以了，感谢大佬
就是现在一定要配置自己豆瓣账号的cooki了，然后搜4-5本要去机器人验证下，哈哈
是指插件版本，下载一个最新版插件
安装插件出错怎么破？
