httpd_uri: httpd_register_uri_handler: no slots left for registering handler

Postby zliudr » Wed Oct 09, 2019 3:09 pm

Hi, I kept getting "httpd_uri: httpd_register_uri_handler: no slots left for registering handler" even for the first handler I thought I registered. There must be some registration I didn't know about.

Is there any way to find out what's been registered by calling a function?

Can someone point to the library code that handles this so I can add or turn on debug info?

Thanks.

I'm sorry. I think my project changed direction and I didn't continue on the httpd route. I looked up what I wrote down and nothing.

Hello my friend,

I've just solved the problem by specifying the max_uri_handlers on my init_webservice function.

The solution can be seeing below:

Code: Select all

esp_err_t init_webservice(char * base_path, httpd_handle_t * auxserver, rest_server_context_t * auxrest_context)
{
	...
	
	httpd_handle_t server = NULL;
    	httpd_config_t config = HTTPD_DEFAULT_CONFIG();
    	config.max_uri_handlers = 10;
    	config.uri_match_fn = httpd_uri_match_wildcard;
    	...
    	
    	init_routes(server, rest_context);
}
My current project is using 10 routes right now, so I passad this number to config.max_uri_handlers element and thats it.

I hope someone finds this solution useful.
