英文:
String Error : unknown escape sequence: /
问题
我有一个类似这样的字符串:
data-url==\"\/entity\/id\/2439918080\"
如果我在这个字符串上使用Println
,会抛出一个错误unknown escape sequence: /
请参考http://play.golang.org/p/IbURcPc_gZ(注释掉第一条语句就可以工作)
然而,如果我将\/
替换为\u002F
,它就可以完美地打印出来。实际的输入数据中充满了这样编码的URL。有没有办法可以在不改变它为\u002F
的情况下打印出来?
这是来自JSON的实际字符串:
<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"
 data-card-name="summary_large_image"

英文:
I have an incoming string that looks like this
data-url==\"\/entity\/id\/2439918080\"
If I Println
on this string, it throws an error unknown escape sequence: /
See http://play.golang.org/p/IbURcPc_gZ (comment the first statement and it works)
However if I replace \/
with \u002F
it prints perfectly. The actual incoming data is full of such encoded urls. Is there anyway I can print it without having to change it to \u002F
?
Here is the actual string that comes from json
<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"
 data-card-name="summary_large_image"
 data-card-url="http:\/\/t.co\/QqWvUQMs5B"
 data-publisher-id="6721522"
 data-creator-id=""

如果你只是想获取一个有效的字符串:
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==\"\u002Fentity\u002Fid\u002F2439918080\"")
}
英文:
If you are just trying to get a valid string :
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==\"\u002Fentity\u002Fid\u002F2439918080\"")
}
