javascript - 即使在 url 编码后也无法下载带有 % 的文件

Question

我保存了一个文件，其中包含 % and %20

当我点击一个链接时，它指向这个文件。通过使用 javascript 我正在做 encodeURI(filePath) .

获取文件未找到错误，但文件可用。

浏览器Chrome和IE，服务器:IIS服务器

实际网址:http://<servername>/<Folder>/PDF/!%2-!@crackerunit&%_20151029203000_0.pdf

编码的URL:http://<servername>/<Folder>/PDF/!%252-!@crackerunit&%25_20151029203000_0.pdf

Answer 1

请按照以下步骤操作:

 1. Original pdf: !%2-!@crackerunit&%_20151029203000_0.pdf
 Use JavaScript encodeURI: encodeURI("!%2-!@crackerunit&%_20151029203000_0") 
 Resulting output: !%252-!@crackerunit&%25_20151029203000_0.pdf
 Complete url: http://<servername>/<Folder>/PDF/!%252-!@crackerunit&%25_20151029203000_0.pdf
 Once this url is accessed, you receive an exception: A potentially
 dangerous Request. Path  
 value was detected from the client (%). Solve this problem by following  
 step2 

 2. web.config changes:
 <system.web>
   <httpRuntime requestPathInvalidCharacters="" 
   />
 </system.web>
