Hello everybody.
Let's imagine jquery requests:
1)
$.ajax({
method: "POST",
url: "/test",
contentType: "application/json",
data: { "key": "test", "array": ["v1","v2","v3"] }
})
jquery sends data in post form fields something like:
key=test&array[]=v1&array[]=v2&array[]=v3
-> cppcms doesn't aggregate values into single json array via
request().post("array")
(neither "array", nor "array[]")
2)
$.ajax({
method: "POST",
url: "/test",
contentType: "application/json",
data: JSON.stringify({ "key": "test", "array": ["v1","v2","v3"] })
})
now we get content in json string format, but
a) request().post() doesn't work;
b) request doesn't have stream interface to fill cppcms::json::value, so we
have to deal with raw_post_data(), which is not recommended.
Do we have a convenient way to deal with json request?
Thanks.

Hello
Is there a way to deal with json arrays like
{"units" : [{"id":1,"name":"test1"},{"id":2,"name":"test2"}]}
?
I can't force cppcms to load such string into json without error.
The only way is to use nested array as string value for a while :(

Please explain me what are you trying to do as it seems to me from the first glance a valid json. Artyom

All the ways to deserialize this string (or alternative - with nested json
inside array) to cppcms::json::value give undefined result.
load() stops on '[' or something like that.

Show the exact full code, it isn't clear what are you doing/trying to do.

Unbelivable.. i can't reproduce my recent problem anymore.
I broke my head against the wall, but now the simplest code works well.
I beg your pardon, Artyom, guys.. I need a vacation i guess..

How about sending stringify data per parameter if it is an array type? So
plain key=text will be sent normally but array= will have return data of
JSON.stringify.
This will make you to deal with convenient request().post() as before.
Thanks.

i think cppcms not handle it as array, waiting for explanation about
dynamic field on client and send it to server.
thanks

Surely there are obvious solutions: prepare data on client side (if you
can) or use unwanted raw_post_data().
I think that json request data should be handled in a simpler way. Or i
didn't find the way.

It shouldn't. If you test application/json than you should parse it as JSON

Who told you raw_post_data() isn't recommended?

You can just create a temporary istream from the post data and parse
the json - that is what json-rpc API does.
Also CppCMS 1.1 introduced json::parse from range of [char const *,char const *)

I haven't dig into jquery - this is what i've got with it with such
settings.
I was very surpised to see form post fields in place of json with
contentType: "application/json"

My bad. It looks like that was my own decision because of conditional
behaviour of this method.
