您能否建议如何检查 Linux 系统上的操作系统日志以及如何解决此问题?
我在设置 mongoose 时遇到了问题。
这是我的代码:
const { SlashCommandBuilder } = require('@discordjs/builders');
const testSchema = require(`../../Schemas.js/test`);
module.exports = {
data: new SlashCommandBuilder()
.setName('dbtest')
.setDescription('db test'),
async execute(interaction) {
testSchema.findOne({ GuildID: interaction.guild.id, UserID: interaction.user.id}, async(err, data) => {
if (err) throw err;
if (!data) {
testSchema.create({
GuildID: interaction.guild.id,
UserID: interaction.user.id
})
}
if (data) {
console.log(data)
}
})
}
}

如何修复主机/端口缺少参数?
我最近正在使用新的最小托管模型从 .NET 5 MVC 应用程序迁移到 .NET 6 MVC 应用程序。在此迁移过程中,我一次又一次遇到“未找到视图”InvalidOperationException。证明视图位于正确的地图中并且程序在该位置“搜索”它:

正如您所看到的,所有地图和文件名都是一致的。
我已经按照微软的迁移指南一步一步进行操作,但没有成功。就我个人而言,我认为添加端点时出了问题,但我已经尝试了 .NET 6 为我提供的每一个可能的选项来添加默认控制器路由。
app.UseEndpoints(endpoints => {
endpoints.MapDefaultControllerRoute();
endpoints.MapRazorPages();
});

或这个
app.MapControllerRoute(
name: "default",
pattern: "{controller=Home}/{action=Index}/{id?}");

当然还有这个
app.UseEndpoints(endpoints => {
endpoints.MapControllerRoute(
name: "default",
pattern: "{controller=Home}/{action=Index}/{id?}");
endpoints.MapRazorPages();
});

但没有任何效果。在谷歌搜索后,我还没有真正在网上找到任何解决方案,这个问题只会让我陷入迁移困境。我希望有人能指出我正确的方向。
