Downloading chunk to SD Card

[tfhulbert]

Hi Everyone,

I am currently working with the esp_http_client_example program and am having a little bit of trouble accessing chunk data once it has been downloaded.

It seems a little difficult but from the looks of it, I have to pull it from the struct? (which isn't publicly exposed?) Just wanted to check I'm not missing something completely.

I have placed the function down below for reference. Please note the SD write function just writes a char array to the SD card.

Any help is much appreciated!

Code: Select all

static void http_download_chunk()
{
    esp_http_client_config_t config = {
        .url = "REDACTED URL",
        .event_handler = _http_event_handler,
    };
    esp_http_client_handle_t client = esp_http_client_init(&config);
    esp_err_t err = esp_http_client_perform(client);
    if (err == ESP_OK) {
        ESP_LOGI(TAG, "HTTP chunk encoding Status = %d, content_length = %d", esp_http_client_get_status_code(client), esp_http_client_get_content_length(client));
    } else {
        ESP_LOGE(TAG, "Error perform http request %s", esp_err_to_name(err));
    }
    //ESP_LOGI(TAG, "%d", client->response->data_process);
    SD_write_flash_images(BIN_ID, client->response->buffer->output_ptr, (uint32_t)client->response->buffer->raw_len);
    ESP_LOGI(TAG, "Image Written to SD Card %i", client->response->buffer->raw_len);
    esp_http_client_cleanup(client);
}
