-----------------------------------
Summary: IE: fail to process file upload response with special
characters (")
Key: SHINDIG-1761
URL: https://issues.apache.org/jira/browse/SHINDIG-1761
Project: Shindig
Issue Type: Bug
Components: Java
Affects Versions: 2.0.2
Environment: IE
Reporter: Xipan Xiao
The server responds the following HTML content when uploading a file. Inside
the <textarea> element, there is a JSON object. It is a valid JSON string,
however, when this arrives the client side in an iframe, the JSON string
extracted from the <textarea> element is decoded, thus all (") are
converted to (") and that breaks the string. See the following code:
var txt = iframe.document.getElementsByTagName("textarea")[0].value;//this txt
is an invalid JSON string.
For browsers like Firefox that has the window.FormData object, we're using AJAX
to upload files and sever reponses are processed directly, without putting into
an iframe/textarea element. For IE we can't avoid putting the response into an
iframe.
The HTML response that causes the problem:
<html><head></head><body><textarea>{"http://example.com/upload":{"rc":200,"body":"{"errorCode":"InvalidRequest","errorMessage":"An
error occurred while handling reading the API request. The request cannot be
completed."}"}}</textarea></body></html>
