处理空图片 (幽灵图片)

Deficuet commented 3 years ago

写了一个遍历合并转发内容并保存的功能。有时候直接接收合并转发后下载的图片是0KB，就需要返回查找该合并转发右键群聊-查看消息记录，打开消息管理器，找到合并转发后，转发至另一个群并由bot接收，在显示了

[Http] Downloading forward message: succeed

之后就会报该错误，似乎是每有一张图片报一次。每个包含图片的Node都显示为这样（抹掉了发送者信息。发送者信息均显示正常）

Node(senderId=<senderId>, time=1633148151, senderName=<senderName>, messageChain=[mirai:image:])

通过queryUrl()获取到的链接都长这样

日志的一部分，合并转发内每有一张图片就会重复一次该部分

复现

右键群聊-查看消息记录，打开消息管理器
找到一个合并转发后，转发至另一个群并由bot接收

不确定是否一定需要bot遍历合并转发的每一个Node，通过queryUrl()获取每一张图片的链接来复现

版本及相关选项选择

mirai-core: 2.7.1
bot-protocol: ANDROID_PHONE

补充信息

Deficuet commented 3 years ago

从消息管理器里转发给群友看，群友反映也是图片全裂。似乎是腾讯自己的问题？

Nambers commented 3 years ago

看起来像嵌套转发消息的问题因为没找到消息管理器里面的合并转发，我用多选+合并转发一个转发信息(内包含转发信息)和一个文本信息做的，没复现错误其中bot没执行任何回应操作

正常从一个群里多选后合并转发是确认不会有该报错，嵌套的也没事。目前看起来只存在于从消息管理器翻消息记录转发
