Hi all, I'm writing error handling middleware for my application which returns JSON errors and I'm having some issues getting the returned content to be displayed in Firefox. I posted the implementation of the error handler to the list earlier (here's a link http://tinyurl.com/jsonerrorhandler)
If I fetch a url which causes an error using Firefox I see an empty page -- as though no content was being returned by the server. However, if I fetch the same url using curl or through a telnet session I can see that headers and content are being returned. Here's the output from curl > curl http://localhost:5072/queues {"status": {"code": 400, "response": "Bad Request"}, "request": {"url": "http://localhost:5072/queues";, "params": {}}, "error": {"code": 40001, "class": "RequestError: The server cannot complete the request since it is malformed or incorrect.", "detail": {"msg": "Need both start and end to fetch a range", "alternatives": {}, "in": {"start": null, "end": null}}}} And here's a sample telnet session, which shows the headers returned > telnet localhost 5072 Trying 127.0.0.1... Connected to localhost. Escape character is '^]'. GET /queues HTTP/1.1 Host: localhost:5072 User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.9.0.8) Gecko/2009032711 Ubuntu/8.10 (intrepid) Firefox/3.0.8 Accept: text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8 Accept-Language: en-us,en;q=0.5 Accept-Encoding: gzip,deflate Accept-Charset: ISO-8859-1,utf-8;q=0.7,*;q=0.7 Keep-Alive: 300 Connection: keep-alive HTTP/1.0 400 Bad Request Server: PasteWSGIServer/0.5 Python/2.6.1 Date: Wed, 22 Apr 2009 00:39:53 GMT content-type: application/json content-length: 364 {"status": {"code": 400, "response": "Bad Request"}, "request": {"url": "http://localhost:5072/queues";, "params": {}}, "error": {"code": 40001, "class": "RequestError: The server cannot complete the request since it is malformed or incorrect.", "detail": {"msg": "Need both start and end to fetch a range", "alternatives": {}, "in": {"start": null, "end": null}}}} Any suggestions on what might be going wrong here? I'm successfully returning JSON which can be seen in Firefox in non-error conditions, i.e. 2xx return codes. Getting it working right under error conditions seems to be eluding me. Perhaps Firefox is ignoring the content when the HTTP status is not in the successful range. I'd appreciate any advice on how to proceed. Thanks. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "pylons-discuss" group.
