Question

我有以下需要转换为YAML的json

{
  "siteidparam": "lid",
  "sites": [
    {
      "name": "default",
      "routingmethod": {
        "method": "urlparam",
        "siteid": "default",
        "urlpath": "default"
      }
    },
    {
      "name": "csqcentral",
      "routingmethod": {
        "method": "urlparam",
        "siteid": "capitolsquare",
        "urlpath": "csq"
      }
    }
  ]
}

我使用online JSON to YAML converter并提供了以下输出

---
  siteidparam: "lid"
  sites: 
    - 
      name: "default"
      routingmethod: 
        method: "urlparam"
        siteid: "default"
        urlpath: "default"
    - 
      name: "csqcentral"
      routingmethod: 
        method: "urlparam"
        siteid: "capitolsquare"
        urlpath: "csq"

当我尝试将同一个生成的YAML转换回json from the online service时，它会给出＆＃34;无法解析＆＃34;异常。

1。）在YAML中表示上述jsons的正确方法是什么？

我想在golang程序中阅读这种YAML。为此，我使用的是spf13 / viper库，但是我找不到任何能够解码这个数组对象之王的方法。

2.。）如何使用毒蛇在golang中阅读这种YAML？示例代码会有所帮助。

Answer 1

代码很难看，但看起来这个库不喜欢嵌套的对象数组。

package main

import (
    "bytes"
    "fmt"
    "github.com/spf13/viper"
)

func main() {
    viper.SetConfigType("yaml")
    var yamlExample = []byte(`---
  siteidparam: "lid"
  sites:
    -
      name: "default"
      routingmethod:
        method: "urlparam"
        siteid: "default"
        urlpath: "default"
    -
      name: "csqcentral"
      routingmethod:
        method: "urlparam"
        siteid: "capitolsquare"
        urlpath: "csq"`)

    viper.ReadConfig(bytes.NewReader(yamlExample))

    fmt.Printf("%s\n", viper.GetString("siteidparam"))

    sites := viper.Get("sites").([]interface{})
    for i, _ := range sites {
        site := sites[i].(map[interface{}]interface{})
        fmt.Printf("%s\n", site["name"])
        routingmethod := site["routingmethod"].(map[interface{}]interface{})
        fmt.Printf("  %s\n", routingmethod["method"])
        fmt.Printf("  %s\n", routingmethod["siteid"])
        fmt.Printf("  %s\n", routingmethod["urlpath"])
    }
}

Answer 2

将YAML解析为JSON的问题是每个项目中有两个空格。它应该是这样的：

---
siteidparam: "lid"
sites: 
  - 
    name: "default"
    routingmethod: 
      method: "urlparam"
      siteid: "default"
      urlpath: "default"
  - 
    name: "csqcentral"
    routingmethod: 
      method: "urlparam"
      siteid: "capitolsquare"
      urlpath: "csq"

关于您的第二个问题，请在下面找到有关如何实现该问题的简单摘要：

package main

import (
    "bytes"
    "fmt"
    "github.com/spf13/viper"
)

func main() {
    viper.SetConfigType("yaml") // or viper.SetConfigType("YAML")
    var yamlExample2 = []byte(`
---
siteidparam: "lid"
sites:
  -
    name: "default"
    routingmethod:
      method: "urlparam"
      siteid: "default"
      urlpath: "default"
  -
    name: "csqcentral"
    routingmethod:
      method: "urlparam"
      siteid: "capitolsquare"
      urlpath: "csq"
`)
    viper.ReadConfig(bytes.NewBuffer(yamlExample2))
    fmt.Println(viper.Get(`sites`))
}
