将参数从 swfupload/uploadify 传递到 Rails 应用程序 - 损坏了吗？

我有一个 uploadify 组件，它将文件发送回 Rails 应用程序。我在某些时候注意到的问题是，对于某些特殊值，传递的数据会被闪存对象更改。

在客户端，我有

 $(document).ready(function() {
   $('#photo_image').uploadify({
    ...
    'scriptData': {
       authenticity_token = 'M++Q3HNclKS7QBEM71lkF/8IkjTwr2JdtqJ4WNXVDro='
     ...
     }
   });
 });

Rails 得到的结果：

"authenticity_token"=>"M  Q3HNclKS7QBEM71lkF/8IkjTwr2JdtqJ4WNXVDro="

当令牌中没有“+”符号时，一切正常。看起来闪光灯正在以某种方式改变字符串。知道如何逃脱吗？我尝试了 CGI.escape，但结果完全相同，“+”被删除......

原文

I have an uploadify component, which sends the files back to rails application. The problem I noticed at some point is, that for some special values data passed along are altered by the flash object.

On the client side I have

 $(document).ready(function() {
   $('#photo_image').uploadify({
    ...
    'scriptData': {
       authenticity_token = 'M++Q3HNclKS7QBEM71lkF/8IkjTwr2JdtqJ4WNXVDro='
     ...
     }
   });
 });

What Rails is getting:

"authenticity_token"=>"M  Q3HNclKS7QBEM71lkF/8IkjTwr2JdtqJ4WNXVDro="

When there is no '+' sign in the token everything works just fine. It looks like the flash is altering the string somehow. Any idea how to escape it? I tried CGI.escape, but result is exactly the same, '+' are stripped...

您必须使用encodeURIComponent()来编码特殊字符：

$(document).ready(function() {
   $('#photo_image').uploadify({
    ...
    'scriptData': {
       authenticity_token = encodeURIComponent('M++Q3HNclKS7QBEM71lkF/8IkjTwr2JdtqJ4WNXVDro=')
     ...
     }
   });
 });

You have to use encodeURIComponent() to encode special characters:

$(document).ready(function() {
   $('#photo_image').uploadify({
    ...
    'scriptData': {
       authenticity_token = encodeURIComponent('M++Q3HNclKS7QBEM71lkF/8IkjTwr2JdtqJ4WNXVDro=')
     ...
     }
   });
 });
