Go中开箱即用的JSON编码非常好,但我需要通过添加图层来使输出与特定格式匹配.我已经找到了一种方法,但希望有一种比我正在做的方式更简单的方法.
下面是我如何做的一个例子.
import (
"bytes"
"encoding/json"
"encoding/xml"
"fmt"
)
type Query struct {
XMLName xml.Name `xml:"http://marklogic.com/appservices/search query" json:"-"`
Format int `xml:"-" json:"-"`
Queries []interface{} `xml:",any" json:"queries"`
}
type TermQuery struct {
XMLName xml.Name `xml:"http://marklogic.com/appservices/search term-query" json:"-"`
Terms []string `xml:"http://marklogic.com/appservices/search text" json:"text"`
Weight float64 `xml:"http://marklogic.com/appservices/search weight,omitempty" json:"weight,omitempty"`
}
// use fakeQuery to avoid an infinite loop
type fakeQuery Query
//MarshalJSON for Query struct in a special way to add wraping {"query":...}
func (q Query) MarshalJSON() ([]byte, error) {
return wrapJSON(`query`, fakeQuery(q)) …Run Code Online (Sandbox Code Playgroud)
