HTTP server fails after a while.

[hououin_kyouma]

Hello I'm trying to use GET method with Telegram api.

Code: Select all

static esp_err_t getUpdates_test (void)
{
    char output_buffer[MAX_HTTP_OUTPUT_BUFFER] = {0};   // Buffer to store response of http request
    // int content_length = 0;
    char _msg_update_id_append[16] = "";
    char url[512] = "";

    /* Creating the string of the url*/
    //Copy the url+TOKEN
    strcat(url, url_string);
    strcat(url, "/getUpdates?limit=1&offset=");
    sprintf(_msg_update_id_append, "%d", _msg_update_id);
    strcat(url, _msg_update_id_append);
    
    ESP_LOGI(TAG3, "url string es: %s", url);

    esp_http_client_config_t config = {
        .url = url,
        .transport_type = HTTP_TRANSPORT_OVER_SSL,
        .event_handler = _http_event_handler,
        .cert_pem = telegram_certificate_pem_start,
        .method = HTTP_METHOD_GET,
    };

    ESP_LOGW(TAG3, "Iniciare");

    esp_http_client_handle_t client = esp_http_client_init(&config);

    ESP_LOGW(TAG3, "Enviare un mensaje a un chat");
    ESP_LOGW(TAG3, "Open");

    esp_err_t err = esp_http_client_open(client, 0);
    if (err != ESP_OK)
    {
        ESP_LOGE(TAG, "Failed to open HTTP connection: %s", esp_err_to_name(err));
        esp_http_client_cleanup(client);
    }

    ESP_LOGI(TAG, "client connection open");

    int64_t content_length = esp_http_client_fetch_headers (client);
    ESP_LOGI(TAG, "content_length= %lld", content_length);

    int total_read_len = 0, read_len;

    char *buffer = malloc ((size_t) (content_length + (int64_t) 1));
    bzero (buffer, (size_t) (content_length + (int64_t) 1));

    if (total_read_len < content_length)
    {
        read_len = esp_http_client_read (client, buffer, content_length);

        if (read_len <= 0)
	    {
	        ESP_LOGE(TAG, "Error read data");
	        return ESP_FAIL;
	    }

        buffer[read_len] = 0;
        
        ESP_LOGI(TAG, "read_len = %d", read_len);
    }

    ESP_LOGI(TAG, "HTTP Stream reader Status = %d, content_length = %d",
	            esp_http_client_get_status_code (client),
	            (int) esp_http_client_get_content_length (client));

    free (buffer);

    err = esp_http_client_close(client);
    if (err != ESP_OK)
    {
        ESP_LOGE(TAG, "Failed to close HTTP connection: %s", esp_err_to_name(err));
        esp_http_client_cleanup(client);
    }

    ESP_LOGW(TAG, "Limpiare");

    ESP_LOGI(TAG, "esp_get_free_heap_size: %ld", (long)esp_get_free_heap_size ());

    return ESP_OK;
}

And my function is working several times. After that I get an error like below:

I could not figure it out. Why this function fails?

Thanks in advance.

You clean up the client first, then try to close its connection.

Among other things, your code generally needs more structured error checking and handling.

mbedtls_ssl_handshake returned -0x2700

The error code means that the certificate failed verification. Are you sure your certificate is setup correctly?

Hi I can use POST method in sendPhoto function continuosly without any problem with same certificate. When I try to GET method it crashes after a while.
