<p>Hi,</p>
<p>i'm doing the issue <a moz-do-not-send="true"
class="moz-txt-link-freetext"
href="https://github.com/kimchi-project/wok/issues/147">https://github.com/kimchi-project/wok/issues/147</a>,
and got a problem to deal with exceptions and Javascript. I got
this code at src/wok/root.py:<br>
<br>
# check for repetly<br>
l = len(self.failed_logins)<br>
if l >= 3:<br>
<br>
# verify if timeout is still valid<br>
last_try = self.failed_logins[l -1]<br>
if time.time() < (last_try["time"] +
self.fail_timeout):<br>
details = e = UnauthorizedError("WOKAUTH0004E",<br>
{"seconds":
self.fail_timeout})<br>
log_request(code, params, details, method, 403)<br>
import pdb;pdb.set_trace()<br>
raise cherrypy.HTTPError(403, e.message)<br>
return e.message<br>
<br>
<br>
So, it may raise an exception. I want to filter this exception
at UI. So i got this code:</p>
<p><br>
</p>
<p> wok.login(settings, function(data) {<br>
var query = window.location.search;<br>
var next = /.*next=(.*?)(&|$)/g.exec(query);<br>
<br>
if (next) {<br>
var next_url = decodeURIComponent(next[1]);<br>
}<br>
else {<br>
var lastPage = wok.cookie.get('lastPage');<br>
var next_url = lastPage ?
lastPage.replace(/\"/g,'') : "/";<br>
}<br>
wok.cookie.set('roles',JSON.stringify(data.roles));<br>
window.location.replace(window.location.pathname.replace(/\/+login.html/,
'') + next_url);<br>
}, function(jqXHR, textStatus, errorThrown) {<br>
if (jqXHR.responseText == "") {<br>
$("#messUserPass").hide();<br>
$("#missServer").show();<br>
} else {<br>
$("#missServer").hide();<br>
$("#messUserPass").show();<br>
}<br>
$("#messSession").hide();<br>
$("#logging").hide();<br>
$("#login").show();<br>
});<br>
<br>
The issue is:<br>
<br>
1) If i raise a cherrypy.HTTPError, i got a html error with the
message i created on the code. Here is an example <a
moz-do-not-send="true" class="moz-txt-link-freetext"
href="http://pastebin.com/AjkWwHBz">http://pastebin.com/AjkWwHBz</a>.
The message is there, but i must parse it.<br>
<br>
</p>

Take a look at root.py lines 47-58. There is set some error handlers
according to error code. Probably, the default error handler for 403
is a HTML page set by cherrypy.<br>
You will need to add a specify 403 error handler for your matters.<br>

<p> 2) If i raise a InvalidOperation or other exception from wok,
i receive a error 500:<br>
</p>
<p> {<br>
"reason":"The server encountered an unexpected condition
which prevented it from fulfilling the request.",<br>
"code":"500 Internal Server Error" <br>
}<br>
</p>

<br>
InvalidOperation will raise a 500 error code. The other message is
usually used when an exception was not catch by anything. In that
case, you should see an traceback in the logs reporting the original
exception.<br>

I want to receive a json with the error, to make it to parse
