在已知结构体解析时
下面解析中，传入的json中，相比较多出一些结构键值，不影响转换。 如下所示：
`
// You can edit this code! // Click here and start typing. package main
import ( “bytes” “encoding/json” “fmt” “io” )
const (
DELETE_BODY_NORMAL = {
"xlb_name":"lvs1",
"xlb_networks":[{
"cidr_v4":"12.62.40.0/24",
"cidr_v6":"5efe:ffff:0:f101::/116",
"cc": "55"
}],
"extern": "66"
}
)
type Cidr struct {
V4 string json:"cidr_v4"
V6 string json:"cidr_v6"
}
type NetworksDeleteParams struct {
XlbName string json:"xlb_name"
XlbNetWorks []Cidr json:"xlb_networks"
}
func BodyDecodeToJson(body io.Reader, v interface{}) (err error) { defer func() { if r := recover(); r != nil { err = fmt.Errorf(“decode panic”) } }() if err = json.NewDecoder(body).Decode(v); err != nil { return err } return nil }
func main() { delParams := NetworksDeleteParams{} body := bytes.NewBufferString(DELETE_BODY_NORMAL) BodyDecodeToJson(body, &delParams) fmt.Println(“Hello, 世界”) fmt.Println(delParams) }
`golang
缺少键值结构时，转化struct
如下所示，json字符串中缺少了name字段，解析后，struct的值使用对应类型的空值赋值
`
// You can edit this code! // Click here and start typing. package main
import ( “bytes” “encoding/json” “fmt” “io” )
const (
DELETE_BODY_NORMAL = {
"xlb_networks":[{
"cidr_v4":"12.62.40.0/24",
"cidr_v6":"5efe:ffff:0:f101::/116",
"cc": "55"
}],
"extern": "66"
}
)
type Cidr struct {
V4 string json:"cidr_v4"
V6 string json:"cidr_v6"
}
type NetworksDeleteParams struct {
XlbName string json:"xlb_name"
XlbNetWorks []Cidr json:"xlb_networks"
}
func BodyDecodeToJson(body io.Reader, v interface{}) (err error) { defer func() { if r := recover(); r != nil { err = fmt.Errorf(“decode panic”) } }() if err = json.NewDecoder(body).Decode(v); err != nil { return err } return nil }
func main() { delParams := NetworksDeleteParams{} body := bytes.NewBufferString(DELETE_BODY_NORMAL) BodyDecodeToJson(body, &delParams) fmt.Println(“Hello, 世界”) fmt.Println(delParams) fmt.Println(delParams.XlbName == “”) } ——————- Hello, 世界 { [{12.62.40.0/24 5efe:ffff:0:f101::/116}]} true
Program exited.
