以上是我在尝试 GET 方法时遇到的 go-swagger 服务器生成的错误，它使用 chrome 浏览器请求 /admin 路由，该路由指向 qor 仪表板。我在 main.go 中使用 gorilla/mux 实现了 qor 仪表板路由处理，如下所示：

Admin := dashboard.SetupAdmin() // I made a dashboard package that sets up the qor dashboard config

adminMux := http.NewServeMux()
Admin.MountTo("/admin", adminMux)

r := mux.NewRouter()
r.PathPrefix("/admin").Handler(adminMux)
r.PathPrefix("/").Handler(api.Serve(nil))

http.Handle("/", r)

srv := &http.Server{
    Handler: r,
    Addr:    "127.0.0.1:8080",
    // Good practice: enforce timeouts for servers you create!
    WriteTimeout: 15 * time.Second,
    ReadTimeout:  15 * time.Second,
}

log.Fatal(srv.ListenAndServe())

我也试过用 vanilla net/http 替换上面的代码：

Admin := dashboard.SetupAdmin()

mux := http.NewServeMux()
Admin.MountTo("/admin", mux)
mux.Handle("/", api.Serve(nil))

http.ListenAndServe(":8080", mux)

但我仍然遇到与本文顶部相同的错误。

我已经删除并保留了相同的 qor 仪表板管理代码并运行服务器并调用其他路由连接、插入和删除附加的 postgres 数据库中的内容，这些路由工作得很好。

我觉得我错过了一些关于路由的小东西，但我已经分叉了 qor 仪表板项目，并且如果他们需要修复或需要更改以使用 go-swagger 生成的服务器，我愿意修复它们。我只是不知道从哪里开始。

也许该Admin.MountTo("/admin", mux)功能无法正常工作？

在 /admin 路由上调用 GET 方法会导致本文顶部的错误。

以下是关于集成的 qor 仪表板文档：https ://doc.getqor.com/admin/integration.html

以下是自定义服务器上的 go-swagger 文档：https ://goswagger.io/tutorial/custom-server.html

任何帮助表示赞赏。:)
