Hello,
I too have been trying figure out how to process JSON from GET and POST
requests using tntnet.
I do not know what the best way is, but I have discovered, through trial and
error, a way. If anyone knows of a better method, please let me know.
If one has some simple JSON such as
{"String":"abcd"}
simply adding
<%args>
std::string String;
</%args>
to the receiving module will work. The variables can then be processed
(magically) as if they came from a normal GET or POST rather than something
involving JSON.
If one has more complex JSON such as
[{"ID":"5","String":"abcd"},{"User":"3","ViewData":true,"EditData":true},{"User”:"5","ViewData":true,"EditData":true}{"User”:"7","ViewData":false,"EditData":true}{"User”:"9","ViewData":false,"EditData":false}]
one has to write a deserializer for the receiving module. A example to follow
can be found at http://pastebin.com/HLJLbTSE
To feed the data into the deserializer one needs to add something like this to
the receiving module (I have only tested POST, but I assume it will also work
for GET):
std::string z;
if(qparam.paramcount()){
z = tnt::stringTo<std::string>("z", "std::string", qparam.param(0),
reply.out().getloc());
}
std::istringstream in(z);
cxxtools::JsonDeserializer unjson(in);
Please note that qparam is not declared in the .ecpp file. The declaration is
added when ecpp converts it to .cpp.
For the record, I am using Zepto rather than jQuery, but I don’t think that
should matter at all.
