我可以将 3rd 方包导入 golang playground吗

2019年5月14日起it is now possible(Brad Fitzpatrick起)！

#Golang操场现在支持第三方导入，通过https://proxy.golang.org/将其吸引进来

示例:https://play.golang.org/p/eqEo7mqdS9l?

Multi-file support & few other things up next.
Report bugs at golang/go issue 31944, or here on the tweeters.

(在"multiple file" support号上，见，自5月以来.2019年16日，"Which packages may be imported in the go playground?":见AN example here)

netbrain表示in the comments，另example表示:

在操场上:

package main

import (
    "fmt"

    "gonum.org/v1/gonum/mat"
)

func main() {
    v1 := mat.NewVecDense(4,[]float64{1,2,3,4})
    fmt.Println(mat.Dot(v1,v1))
}

我们给出‘30’，使用mat.NewVecDense()创建列向量，使用mat.Dot()返回v1和v1的元素乘积之和

重点是:gonum/mat是Go Standard Library的not部分.

原始答案:

关于围棋playground 的最完整的文章仍然是"Inside the Go Playground"，其中提到:

• godoc/static/static.go(用于操场上显示的默认围棋程序)
• golang/tools/playground用于源代码，playground/socket/socket.go用于从操场编辑器构建和执行程序.

None of those processes support importing a remote package (that would be accessed over the internet).
It is very much a self-contained system (that you can run locally as well as using it from play.golang.org), with multiple features stubbed or faked, like the network:

Like the file system, the playground's network stack is an in-process fake implemented by the syscall package.
It permits playground projects to use the loopback interface (127.0.0.1).
Requests to other hosts will fail.

更新2017:

您有其他 Select :

• iafan/goplayspace
• xiam/go-playground

但他们仍然使用官方的Go Playround服务来构建和运行Go代码，因此仍然不允许外部导入.
