JSON requests in C using libcurl

Question

I\'m defining a PUT request with a JSON request body using libcurl in C.

This how I\'m doing it:

    sprintf(jsonObj, \"\\\"name\\\" : \\\"%s\\\", \\         


        

Answer 1

Had this same problem when posting data to node-red with json parser.
Solution for me was to treat string as a HTML

#include 

int main (int argc, char *argv[]) {
    CURL *curl;
    CURLcode res;

    curl_global_init(CURL_GLOBAL_ALL);
    curl = curl_easy_init();
    if (curl == NULL) {
        return 128;
    }
    struct curl_slist *headers = NULL;
    curl_slist_append(headers, "Content-Type: application/json");
    curl_easy_setopt(curl, CURLOPT_URL, #yourURL);
    curl_easy_setopt(curl, CURLOPT_CUSTOMREQUEST, "POST");
    curl_easy_setopt(curl, CURLOPT_HTTPHEADER, headers);
    curl_easy_setopt(curl, CURLOPT_POSTFIELDS, "age=42&sex=male");

    res = curl_easy_perform(curl);

    curl_easy_cleanup(curl);
    curl_global_cleanup();
    return res;
}

Hope someone will find it helpful.
