Bad characters in request body

[edrezen]

Hello,

I am trying to retrieve a request body (supposed to be some json object) and I receveive some null characters. Here is  a snippet :

    // *method: POST
    void echo (ngrest::MessageContext& context)
    {
        ngrest::HttpRequest*  request  = static_cast<ngrest::HttpRequest*> (context.request);
       
        for (size_t i=0; i<request->bodySize; i++)  
        {
            printf ("%d ", request->body[i]);
        }
        printf ("\n");
    }

For instance, I send:

curl -X POST -H 'Content-Type: application/json' -i http://localhost:9098/foobar --data '{"aaa":"bbb"}'

and my 'echo' service displays:

123 34 97 97 97 0 58 34 98 98 98 0 0

I receive the correct number of characters, but there are 3 zero values that are obviously wrong.

Am I missing something ?

Thank you in advance

Hi,

It's ok, because of JSON parser modifies source buffer upon parsing. It replaces some characters to NUL, to make it possible to re-use source buffer for node names and values. This is as designed for performance optimization.
