go从文件中读取json字符串并转换

将要读取的文件的一部分

[  {    "children": [      {        "children": [          {            "code": 110118,            "name": "密云区"          },          {            "code": 110119,            "name": "延庆区"          }        ],        "code": 110000,        "name": "北京市"      }    ],    "code": "110000",    "name": "北京市(京)"  },  {    "children": [      {        "children": [          {            "code": 120118,            "name": "静海区"          },          {            "code": 120119,            "name": "蓟州区"          }        ],        "code": 120000,        "name": "天津市"      }    ],    "code": "120000",    "name": "天津市(津)"  },  {    "children": [      {        "code": 820000,        "name": "澳门特别行政区（澳）"      }    ],    "code": "820000",    "name": "澳门特别行政区(澳)"  },  {    "code": "710000",    "name": "台湾省(台)"  }]

package mainimport (    "bufio"    "fmt"    "io"    "os"    "encoding/json")type County struct{     Code    int    Name    string}type City struct {    Children []County    Code    int    Name    string}type Province struct{    Children []City    Code    string    Name    string}func main() {    //打开文件    inputFile, inputError := os.Open("xzqh.json")    if inputError != nil {        return    }    defer inputFile.Close()    //按行读取文件    var s string    inputReader := bufio.NewReader(inputFile)    for {        inputString, readerError := inputReader.ReadString('')        if readerError == io.EOF {            break        }        s = s + inputString    }    fmt.Printf("all: %s", s)        //json字符串转化为结构体    fmt.Println("-------------------------------------------------")    var province []Province    if err := json.Unmarshal([]byte(s), &province); err == nil {        fmt.Println(province)        for i:=0;i<len(province);i++ {            fmt.Println(province[i].Name);        }    }else{        fmt.Println("转换失败")    }}

走过的坑： 1.接受json的字符串的结构体成员变量需要大写，否则无法解析
