Content-Type: multipart/form-data;boundary=A 提交内容：

尝试了在模板开头添加了Content-Type等其他操作，没有用 和网上大部分关于multiline的文章比对后没发现什么问题

MiraiConsole v2.13.0-RC2 net.mamoe.mirai-api-http v2.6.2

[Guation]

你这个boundary有点短 不知道是不是这个原因

[abcdefghHIM]

你这个boundary有点短 不知道是不是这个原因

刚刚试了增长boundary，没有效果，依然是这个错误

[cssxsh]

请尝试使用 https://github.com/project-mirai/mirai-api-http/releases/tag/v2.7.1

如果你是 mcl 自动更新 请将 config.json 中的 stable-v2 换成 maven-stable

我查看了各种相关资料，确实不像是 multiline 的问题。

可是，我发现你截图的报文是有问题的。对于 file 类型的 multipart item，应该是有 Content-Type 的，但是你截图的报文中没有。所以 server 应该是按照 text 类型解析了 body 里的内容。中间大概率出现了 0x0D 或 0x0A 触发了 multiline 的判定。

这是我抓包获取的正常报文
