字符串错误:未知转义序列:/

Question

我有一个输入字符串，看起来像这样

data-url=="/entity/id/2439918080"

如果在此字符串上输入Println，则抛出错误unknown escape sequence: /

参见http://play.golang.org/p/IbURcPc_gZ(注释第一个语句，它可以工作)

然而，如果我用u002F代替/，它打印完美。实际的传入数据充满了这种编码的url。有没有办法我可以打印它，而不必把它改成u002F ?

这是来自json

的字符串

  <div class="card2 media-container portrait" data-card2-name="summary_large_image">
    
    <div class="js-macaw-cards-iframe-container"
  data-src="/i/entity/tfw/v1/3298718080?cardname=summary_large_image&earned=true"
  data-autoplay-src="/i/cards/tfw/v1/632987845439918080?cardname=summary_large_image&earned=true"

如果您只是想获得一个有效的字符串:

package main
import "fmt"
import("strings")
func main() {
    s := `data-url=="/entity/id/2439918080"`
    s = strings.Replace(s,"\","",-1)
    println(s)
    //Replace / with u002F works fine
    fmt.Println("data-url=="u002Fentityu002Fidu002F2439918080"")
}
