This function must be the first to be called default values will be assumed for the configuration values that are not explicitly defined by the user.Įsp_http_client_perform(): Performs all operations of the esp_http_client - opening the connection, exchanging data and closing the connection (as required), while blocking the current task until its completion. a HTTP client handle based on the given esp_http_client_config_t configuration.
