go語(yǔ)言提供了json的編解碼包，json字符串作為參數(shù)值傳輸時(shí)發(fā)現(xiàn)，json.Marshal生成json特殊字符、>、會(huì)被轉(zhuǎn)義。
type Test struct {
Content string
}
func main() {
t := new(Test)
t.Content = "http://www.baidu.com?id=123test=1"
jsonByte, _ := json.Marshal(t)
fmt.Println(string(jsonByte))
}
{"Content":"http://www.baidu.com?id=123\u0026test=1"}

GoDoc描述
String values encode as JSON strings coerced to valid UTF-8,
replacing invalid bytes with the Unicode replacement rune.
The angle brackets “” and “>” are escaped to “\u003c” and “\u003e”
to keep some browsers from misinterpreting JSON output as HTML.
Ampersand “” is also escaped to “\u0026” for the same reason.
This escaping can be disabled using an Encoder that had SetEscapeHTML(false) alled on it.
json.Marshal 默認(rèn) escapeHtml 為true,會(huì)轉(zhuǎn)義 、>、
func Marshal(v interface{}) ([]byte, error) {
e := encodeState{}
err := e.marshal(v, encOpts{escapeHTML: true})
if err != nil {
return nil, err
}
return e.Bytes(), nil
}
解決方案
方法一：
content = strings.Replace(content, "\\u003c", "", -1)
content = strings.Replace(content, "\\u003e", ">", -1)
content = strings.Replace(content, "\\u0026", "", -1)
這種方式比較直接，硬性字符串替換。比較憨厚
方法二：
文檔中寫(xiě)到This escaping can be disabled using an Encoder that had SetEscapeHTML(false) alled on it.
我們先創(chuàng)建一個(gè)buffer用于存儲(chǔ)json
創(chuàng)建一個(gè)jsonencoder
設(shè)置html編碼為false
type Test struct {
Content string
}
func main() {
t := new(Test)
t.Content = "http://www.baidu.com?id=123test=1"
bf := bytes.NewBuffer([]byte{})
jsonEncoder := json.NewEncoder(bf)
jsonEncoder.SetEscapeHTML(false)
jsonEncoder.Encode(t)
fmt.Println(bf.String())
}
{"Content":"http://www.baidu.com?id=123test=1"}
Process finished with exit code 0
查看文檔和源碼還是解決問(wèn)題的好方法。
