HttpRequest()

		struct curl_slist *	headers,

	)

HTTP GET & POST request using cURL.

Basic HTTP request using CURL.

Most initialisation is done outside of this function. This function just handles the HTTP request and puts the data inside a provided cJSON object. Note this function has a memory leak on a Mac M1 -> (curl_easy_perform()) has 13 leaks, totalling 496 bytes per call.

const char *URL = "https://www.example.com";
 
// Create some headers (more may be needed depending on application)
struct curl_slist *headers = NULL;
headers = curl_slist_append(headers, "Content-Type: application/json");
 
// Create a cJSON object to hold the response
cJSON *response = NULL;
CURLcode result = HttpRequest(&response, URL, headers, 0, NULL);
 
// Free memory
curl_slist_free_all(headers);
cJSON_Delete(response);

Parameters

response	The cJSON response to populate with JSON.
URL	The request URL.
headers	Headers to include in request.
post	Interger flag to request POST request (set to 1).
body	POST request body.

Returns

Status code representing the response status.
