From f90649eb2b0988c771fa329ba7a0a5ba81fe2396 Mon Sep 17 00:00:00 2001 From: Richard van der Hoff Date: Fri, 10 Nov 2017 09:15:39 +0000 Subject: Fix 500 on invalid utf-8 in request If somebody sends us a request where the the body is invalid utf-8, we should return a 400 rather than a 500. (json.loads throws a UnicodeError in this situation) We might as well catch all Exceptions here: it seems very unlikely that we would get a request that *isn't caused by invalid json. --- synapse/http/servlet.py | 3 ++- 1 file changed, 2 insertions(+), 1 deletion(-) diff --git a/synapse/http/servlet.py b/synapse/http/servlet.py index 8118ee7cc2..71420e54db 100644 --- a/synapse/http/servlet.py +++ b/synapse/http/servlet.py @@ -167,7 +167,8 @@ def parse_json_value_from_request(request): try: content = simplejson.loads(content_bytes) - except simplejson.JSONDecodeError: + except Exception as e: + logger.warn("Unable to parse JSON: %s", e) raise SynapseError(400, "Content not JSON.", errcode=Codes.NOT_JSON) return content -- cgit 1.4.1
