Detailed Description

Typedef Documentation

http_resource_dynamic_cb_t

http_resource_dynamic_cb_t

#include <zephyr/net/http/server.h>

Callback used when data is received.

Data to be sent to client can be specified.

Parameters

client	HTTP context information for this client connection.
status	HTTP data status, indicate whether more data is expected or not.
data_buffer	Data received.
data_len	Amount of data received.
user_data	User specified data.

Returns

>0 amount of data to be sent to client, let server to call this function again when new data is received. 0 nothing to sent to client, close the connection <0 error, close the connection.

http_resource_websocket_cb_t

http_resource_websocket_cb_t

#include <zephyr/net/http/server.h>

Callback used when a Websocket connection is setup.

The application will need to handle all functionality related to the connection like reading and writing websocket data, and closing the connection.

Parameters

ws_socket	A socket for the Websocket data.
user_data	User specified data.

Returns

0 Accepting the connection, HTTP server library will no longer handle data to/from the socket and it is application responsibility to send and receive data to/from the supplied socket. <0 error, close the connection.

Enumeration Type Documentation

http_data_status

enum http_data_status

#include <zephyr/net/http/server.h>

Indicates the status of the currently processed piece of data.

Enumerator
HTTP_SERVER_DATA_ABORTED	Transaction aborted, data incomplete.
HTTP_SERVER_DATA_MORE	Transaction incomplete, more data expected.
HTTP_SERVER_DATA_FINAL	Final data fragment in current transaction.

http_resource_type

enum http_resource_type

#include <zephyr/net/http/server.h>

HTTP server resource type.

Enumerator
HTTP_RESOURCE_TYPE_STATIC	Static resource, cannot be modified on runtime.
HTTP_RESOURCE_TYPE_DYNAMIC	Dynamic resource, server interacts with the application via registered http_resource_dynamic_cb_t.
HTTP_RESOURCE_TYPE_WEBSOCKET	Websocket resource, application takes control over Websocket connection after and upgrade.

Function Documentation

http_server_start()

int http_server_start

(

void

)

#include <zephyr/net/http/server.h>

Start the HTTP2 server.

The server runs in a background thread. Once started, the server will create a server socket for all HTTP services registered in the system and accept connections from clients (see HTTP_SERVICE_DEFINE).

http_server_stop()

int http_server_stop

(

void

)

#include <zephyr/net/http/server.h>

Stop the HTTP2 server.

All server sockets are closed and the server thread is suspended.
