How to sendi HTTP request and parse JSON response in TIZEN watch using Native?

Question

Hi I'am new to Tizen Development and would like to explore functions/features like what I used in android development. So I want to learn how to post/get HTTP and parse the json response from the URL using Native Tizen watch. Can anyone help me or point me to some tutorials?

You can do this using curl . Here is an example using:

Add these headers

#include <curl/curl.h>
#include <net_connection.h>

And implement like this

    /* Initialize CURL */ 
    CURL *curlHandler = curl_easy_init();


    connection_h connection;

    int conn_err;
    conn_err = connection_create(&connection);
    if (conn_err != CONNECTION_ERROR_NONE) {
        /* Error handling */
        return false;
    }

    if(curlHandler) {
      /* Set CURL parameters */
      curl_easy_setopt(curlHandler, CURLOPT_URL, "http://api.yoururl.com");
      curl_easy_setopt(curlHandler, CURLOPT_CUSTOMREQUEST, "POST");
      curl_easy_setopt(curlHandler, CURLOPT_POSTFIELDS,  jObj);

      /* Perform the request */ 
      CURLcode res = curl_easy_perform(curlHandler);

      /* Check for errors */ 
      if(res != CURLE_OK)
        fprintf(stderr, "CURL failed: %s\n",
                curl_easy_strerror(res));

      /* Clean up */ 
      curl_easy_cleanup(curlHandler);
      json_object_object_del(jObj, "name");
      connection_destroy(connection);
      free(jObj);
  }
