英文:
Convert introspection result to SDL format in Go
问题
我可以从远程的 GraphQL 服务器获取内省结果，现在我想将这个结果（JSON 格式）转换为 SDL 格式。
这是一个示例（链接：https://www.apollographql.com/blog/backend/schema-design/three-ways-to-represent-your-graphql-schema/），展示了我需要的内容，但是是用 JavaScript 编写的。
谢谢。

一种方法是使用https://github.com/CDThomas/graphql-json-to-sdl。
由于它是一个Node.js应用程序，你可以设置、安装等，然后像这样从Go中运行它：
import (
"bytes"
"fmt"
"log"
"os/exec"
)
func main() {
var stdout, stderr bytes.Buffer
jsonFilePath := "./schema.json"
outputFilePath := "./schema.graphql"
comm := fmt.Sprintf("graphql-json-to-sdl %s %s", jsonFilePath, outputFilePath)
sourcePath := "~/.bashrc"
cmd := exec.Command("/bin/sh", "-c", "source "+sourcePath+" ; "+comm)
cmd.Stdout = &stdout
cmd.Stderr = &stderr
err := cmd.Run()
outStr, errStr := string(stdout.Bytes()), string(stderr.Bytes())
fmt.Printf("out:\n%s\nerr:\n%s\n", outStr, errStr)
if err != nil {
log.Fatalf("cmd.Run() failed with %s\n", err)
}
}

One way to do it is with https://github.com/CDThomas/graphql-json-to-sdl
Since it's a node JS application, you could set it up, install it, etc then run it from go like this
import (
"bytes"
"fmt"
"log"
"os/exec"
)
func main() {
var stdout, stderr bytes.Buffer
jsonFilePath := "./schema.json"
outputFilePath := "./schema.graphql"
comm := fmt.Sprintf("graphql-json-to-sdl %s %s", jsonFilePath, outputFilePath)
sourcePath := "~/.bashrc"
cmd := exec.Command("/bin/sh", "-c", "source "+sourcePath+" ; "+comm)
cmd.Stdout = &stdout
cmd.Stderr = &stderr
err := cmd.Run()
outStr, errStr := string(stdout.Bytes()), string(stderr.Bytes())
fmt.Printf("out:\n%s\nerr:\n%s\n", outStr, errStr)
if err != nil {
log.Fatalf("cmd.Run() failed with %s\n", err)
}
}
