String Error : unknown escape sequence: /

问题

我有一个类似这样的字符串：

  1. 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：

  1. <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=""
  data-amplify-content-id=""
  data-amplify-playlist-url=""
  data-full-card-iframe-url="\/i\/cards\/tfw\/v1\/632987845439918080?cardname=summary_large_image&earned=true"
  data-has-autoplayable-media="false">
<\/div>

<\/div>

英文:

I have an incoming string that looks like this

  1. 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

  1.   <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=""
  data-amplify-content-id=""
  data-amplify-playlist-url=""
  data-full-card-iframe-url="\/i\/cards\/tfw\/v1\/632987845439918080?cardname=summary_large_image&earned=true"
  data-has-autoplayable-media="false">
<\/div>

<\/div>



        <div class="entities-media-container js-media-container" style="min-height:0px">
        <\/div>

  <div class="machine-translated-container"><\/div>
    <div class="stats-container stats-container ">
    <\/div>

  <div class="client-and-actions">
  <span class="metadata">
    <span>2:50 PM - 16 Aug 2015<\/span>

Thanks.

如果你只是想获取一个有效的字符串：

  1. package main
  3. import "fmt"
  4. import "strings"
  6. func main() {
  7.         
  8.     s := `data-url==\"/entity/id/2439918080\"`
  9.     s = strings.Replace(s,"\\","",-1)
  10.     println(s)
  11. 	
  12. 	//Replace \/ with \u002F works fine
  13. 	fmt.Println("data-url==\"\u002Fentity\u002Fid\u002F2439918080\"")
  14. }
英文:

If you are just trying to get a valid string :

  1. package main
  3. import "fmt"
  4. import("strings")
  6. func main() {
  7.         
  8.     s := `data-url==\"\/entity\/id\/2439918080\"`
  9.     s = strings.Replace(s,"\\","",-1)
  10.     println(s)
  11. 	
  12. 	//Replace \/ with \u002F works fine
  13. 	fmt.Println("data-url==\"\u002Fentity\u002Fid\u002F2439918080\"")
  14. }
