Creating two webservers problem

[username]

I want to create two webservers. One on port 80 and the other on port 8080.
When I create one, it works. When I add the second it fails. Am I doing it wrong, or is the http_server not capable of doing more than one.

Code: Select all

static const char *TAG = "DualWebServer";

// Handler for requests to the server on port 80
esp_err_t port80_handler(httpd_req_t *req)
{
    httpd_resp_send(req, "Hello from server on port 80!", HTTPD_RESP_USE_STRLEN);
    return ESP_OK;
}

// Handler for requests to the server on port 8080
esp_err_t port8080_handler(httpd_req_t *req)
{
    httpd_resp_send(req, "Hello from server on port 8080!", HTTPD_RESP_USE_STRLEN);
    return ESP_OK;
}

// Function to start a server on a specified port
httpd_handle_t start_http_server1(int port, esp_err_t (*handler)(httpd_req_t *))
{
    httpd_config_t config = HTTPD_DEFAULT_CONFIG();
    config.server_port = port;

    httpd_handle_t server = NULL;
    if (httpd_start(&server, &config) == ESP_OK)
    {
        httpd_uri_t uri = {
            .uri = "/",
            .method = HTTP_GET,
            .handler = handler,
            .user_ctx = NULL};
        httpd_register_uri_handler(server, &uri);
        ESP_LOGI(TAG, "Server started on port %d", port);
        return server;
    }

    ESP_LOGE(TAG, "Failed to start server on port %d", port);
    return NULL;
}

// Function to start a server on a specified port
httpd_handle_t start_http_server2(int port, esp_err_t (*handler)(httpd_req_t *))
{
    httpd_config_t config = HTTPD_DEFAULT_CONFIG();
    config.server_port = port;

    httpd_handle_t server = NULL;
    if (httpd_start(&server, &config) == ESP_OK)
    {
        httpd_uri_t uri = {
            .uri = "/",
            .method = HTTP_GET,
            .handler = handler,
            .user_ctx = NULL};
        httpd_register_uri_handler(server, &uri);
        ESP_LOGI(TAG, "Server started on port %d", port);
        return server;
    }

    ESP_LOGE(TAG, "Failed to start server on port %d", port);
    return NULL;
}

void main(void)
{
   // start wifi stuff left out for clarity 
	
	
    // Start the first HTTP server on port 80
    httpd_handle_t server1 = start_http_server1(80, port80_handler);

    // Start the second HTTP server on port 8080
    httpd_handle_t server2 = start_http_server2(8080, port8080_handler);
    
}

In order to run concurrently, multiple instances of the HTTP server must also be configured to each use a different httpd_config_t::ctrl_port. (Any port should be fine that you don't use for other (UDP) traffic, e.g. (ESP_HTTPD_DEF_CTRL_PORT + 1...n).)

Thank you so much!!!!!

Works now.
