Hi Felix,

I can't find a way to make the simple form post work, along with ajax too, :( .

How should I write the form?

like this?
<form id="form" method="post" action="/test/encoding" enctype="text/ html; charset=utf-8">
    <input name="name" value="测试" />
    <input name="message" value="" />
    <input type="hidden" name="_charset_" value="utf-8" />
    <input type="submit" value="submit" />
  </form>

It won't work.

And this?
<form id="form" method="post" action="/test/encoding" enctype="application/x-www-form-urlencoded; charset=utf-8">
won't work.

And this?
<form id="form" method="post" action="/test/encoding" enctype="multipart/form-data; charset=utf-8">
won't work either.

Ajax Post is like that too.

My page's encoding is utf-8, what should I do?

Hi Felix,

The core problem is, that the browsers generally do not send the
Cotent-Type header with the proper charset parameter. Instead they tend to encode the form post using the same encoding as was used for the HTML
on which the form resides.

Yes, that's the browser's problem.

So if you send the form with

 Content-Type: text/hml; charset=UTF-8

My form really can't be that content type, especially in an ajax request.

So you are not using a normal form post but an AJAX request to send the
data ?

In this case you might want to consider setting the ContentType header
explicitly ?


the POST is sent back encoded in UTF-8 and Sling will happily decode as
UTF-8 as instructed by the _charset_ parameter.

For best (and proven) results:

* Send everything as UTF-8
* Use encoding="multipart/form-data" for your forms
* Keep the _charset_ parameter set to UTF-8 (or utf-8)

Yes, that's what I do. It doesn't work when using  dojo ajax post in
ie(When I use dojo in ie do the ajax post, sling didn't get the
encoding, so it use iso-8859-1 as default).

I do not know enough of dojo and how dojo sends requests, but can't you set the character encoding (or content type) when sending a POST request
with dojo ?


Besides, if sling fix the encoding for the request parameter, then
ContainerRequestParameter's encoding and decoding really seems
unnecessary. Even everything is right, decoded every parameter value in utf-8 then encode it with the same encoding again is an unnecessary waste.

Reencoding does not always take place, but some times it is required.
For example when reading multipart/form-data, Sling must assume an
encoding upfront in case it is not sent by the client. And the safest
bet is ISO-8859-1 which may be used as a transient encoding before
actually encoding in UTF-8.

The reason why this works is, that ISO-8859-1 just takes any byte value
from the inputstream and assumes it to be a character whose character
code is in the 0..255 range.

Felix
