[Cppcms-users] 502 Bad Gateway after Xhr posting plain text and some more questions

[Stanimir M. <sta...@zo...>]

Hi Artyom,

I tried your chat example with dojo and it works.
However, when I send plain text from dojo
and not form post with form=some text i get "502 Bad Gateway" error.

here is the post request:

Host	localhost:8080
User-Agent	Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.9.2.3)
Gecko/20100407 Ubuntu/9.10 (karmic) Firefox/3.6.3

Referer	http://localhost:8080/hello_world/chat
Content-Length	7
Cookie	test=1270049271

here is the content "sssssss"


Also, sometimes when i click multiple times on my test cppcms
application, I get "Segmentation Fault" and my cppcms application
stops?

Another problem is that I can't make the session work even from your
hello_world example. It always refreshes the time?

Greetings,
Stanimir

Ok, indeed there was an issue - I didn't written any response for POST.
Actually the response was empty. Fixed in hello_world.cpp in trunk.

I had to notice an application that output completed (if I do not
write anything...)

So just run svn update.

Few notes:

1st you need to send POST request in form message=ssssss (meaning
it expects "Form" behavior"

Can you bring me the backtrace of segmentation fault?

You can do it with GDB

  gdb your_app

  Crashes

Do you have any session backend defined?

Give me the content of "session" object of the configuration?

At least default build of hello world - going to 

  http://localhost:8080/hello/session

Make sure you are using latest CppCMS version.
Also check if make test passes all tests, if not which one fail?

Yes, I saw that. But what if I need just the content of the post which
is not "Form" behavior.
For example, sending json object without "message" name for it?

My mistake, it works. I somehow missed the file back end in the config.

You can access post data directly using raw_post_data() member function
of http::request().

  std::pair<void *,size_t> post_data = request().raw_post_data();

And analyze this.

-------------------
BTW Json:

CppCMS 1.x.x supports JSON-RPC as well... You may find an 
example of usage in tests/jsonrpc_test.cpp


Best,
  Artyom
