+# HTTP Data Request
+
+## Use Cases
+
+An application can initiate a data request over HTTP. Common HTTP methods include **GET**, **POST**, **OPTIONS**, **HEAD**, **PUT**, **DELETE**, **TRACE**, and **CONNECT**.
+
+## Available APIs
+
+The HTTP request function is mainly implemented by the HTTP module.
+
+To use related APIs, you must declare the **ohos.permission.INTERNET** permission.
+
+The following table describes the related APIs.
+
+| API                                   | Description                           |
+| ----------------------------------------- | ----------------------------------- |
+| createHttp()                              | Creates an HTTP request.                 |
+| request()                                 | Initiates an HTTP request to a given URL.    |
+| destroy()                                 | Destroys an HTTP request.                     |
+| on(type: 'headersReceive')                | Registers an observer for HTTP Response Header events.    |
+| off(type: 'headersReceive')               | Unregisters the observer for HTTP Response Header events.|
+
+## How to Develop
+
+1. Import the required HTTP module.
+2. Create an **HttpRequest** object.
+3. (Optional) Listen for HTTP Response Header events.
+4. Initiates an HTTP request to a given URL.
+5. (Optional) Process the HTTP Response Header event and the return result of the HTTP request.
+
+```js
+import http from '@ohos.net.http';
+
+// Each HttpRequest corresponds to an HttpRequestTask object and cannot be reused.
+let httpRequest = http.createHttp();
+
+// Subscribe to the HTTP response header, which is returned earlier than HttpRequest. You can subscribe to HTTP Response Header events based on service requirements.
+// on('headerReceive', AsyncCallback) will be replaced by on('headersReceive', Callback) in API version 8. 8+
+httpRequest.on('headersReceive', (header) => {
+    console.info('header: ' + JSON.stringify(header));
+});
+
+httpRequest.request(
+    // Set the URL of the HTTP request. You need to define the URL. Set the parameters of the request in extraData.
+    "EXAMPLE_URL",
+    {
+        method: http.RequestMethod.POST, // Optional. The default value is http.RequestMethod.GET.
+        // You can add the header field based on service requirements.
+        header: {
+            'Content-Type': 'application/json'
+        },
+        // This field is used to transfer data when the POST request is used.
+        extraData: {
+            "data": "data to send",
+        },
+        connectTimeout: 60000, // Optional. The default value is 60000, in ms.
+        readTimeout: 60000, // Optional. The default value is 60000, in ms.
+    }, (err, data) => {

+            // Call the destroy() method to release resources after the call is complete.
+            httpRequest.destroy();
+        }
+    }
+);

+# Socket Connection
+
+
+## Use Cases
+
+Your application can transmit data through Socket connections. Currently, the TCP and UDP protocols are supported.
+
+
+## Available APIs

+| constructUDPSocketInstance() | Creates a **UDPSocket** object.|
+| constructTCPSocketInstance() | Creates a **TCPSocket** object.|
+| bind() | Binds the IP address and port number.|
+| send() | Sends data.|
+| close() | Closes a Socket connection.|
+| getState() | Obtains the Socket connection status.|
+| connect() | Connects to the specified IP address and port. This function is supported only for TCP.|
+| getRemoteAddress() | Obtains the peer address of the Socket connection. This function is supported only for TCP. The **connect** API must have been called before you use this API.|
+| on(type: 'message') | Enables listening for **message** events of the Socket connection.|
+| off(type: 'message') | Disables listening for **message** events of the Socket connection.|
+| on(type: 'close') | Enables listening for **close** events of the Socket connection.|
+| off(type: 'close') | Disables listening for **close** events of the Socket connection.|
+| on(type: 'error') | Enables listening for **error** events of the Socket connection.|

+| on(type: 'listening') | Enables listening for **listening** events of the UDPSocket connection. |
+| off(type: 'listening') | Disables listening for **listening** events of the UDPSocket connection. |
+| on(type: 'connect') | Enables listening for **connect** events of the TCPSocket connection. |
+| off(type: 'connect') | Disables listening for **connect** events of the TCPSocket connection.|
+
+
+## How to Develop
+
+The implementation is similar for UDPSocket and TCPSocket. The following uses the TCPSocket as an example.
+
+1. Import the required Socket module.
+
+2. Create a **TCPSocket** object.
+
+3. (Optional) Enable listening for TCPSocket events.
+
+4. Bind the IP address and port number. The port number can be specified or randomly allocated by the system.
+
+5. Set up a connection to the specified IP address and port number.
+
+6. Send data.
+
+7. Enable the TCPSocket connection to be automatically closed after use.
+   
+   ```js
+   import socket from '@ohos.net.socket'
+   
+   // Create a TCPSocket object.
+   let tcp = socket.constructTCPSocketInstance();

+       }
+       console.log("on connect recevied:" + str)
+   });
+   tcp.on('connect', () => {
+       console.log("on connect")
+   });
+   tcp.on('close', () => {

en/application-dev/connectivity/websocket-connection.md

+# WebSocket Connection
+
+
+## Use Cases
+
+You can use WebSocket to establish a bidirectional connection between a server and a client. Before doing this, you need to use the **createWebSocket** API to create a **WebSocket** object and then use the **connect** API to connect to the server. If the connection is successful, the client will receive a callback of the **open** event. Then, the client can communicate with the server using the **send** API. When the server sends a message to the client, the client will receive a callback of the **message** event. If the client no longer needs this connection, it can call the **close** API to disconnect from the server. Then, the client will receive a callback of the **close** event.
+
+If an error occurs in any of the preceding processes, the client will receive a callback of the **error** event.
+
+
+## Available APIs
+
+The WebSocket connection function is mainly implemented by the WebSocket module. To use related APIs, you must declare the **ohos.permission.INTERNET** permission. The following table describes the related APIs.
+
+| API| Description|
+| -------- | -------- |
+| createWebSocket() | Creates a WebSocket connection.|
+| connect() | Establishes a WebSocket connection to a given URL.|
+| send() | Sends data through the WebSocket connection.|
+| close() | Closes a WebSocket connection.|
+| on(type: 'open') | Enables listening for **open** events of a WebSocket connection.|
+| off(type: 'open') | Disables listening for **open** events of a WebSocket connection.|
+| on(type: 'message') | Enables listening for **message** events of a WebSocket connection.|
+| off(type: 'message') | Disables listening for **message** events of a WebSocket connection.|
+| on(type: 'close') | Enables listening for **close** events of a WebSocket connection.|
+| off(type: 'close') | Disables listening for **close** events of a WebSocket connection.|
+| on(type: 'error') | Enables listening for **error** events of a WebSocket connection.|
+| off(type: 'error') | Disables listening for **error** events of a WebSocket connection.|
+
+
+## How to Develop
+
+1. Import the required WebSocket module.
+
+2. Create a **WebSocket** object.
+
+3. (Optional) Subscribe to WebSocket open, message, close, and error events.
+
+4. Establish a WebSocket connection to a given URL.
+
+5. Close the WebSocket connection if it is no longer needed.
+   
+   ```js
+   import webSocket from '@ohos.net.webSocket';
+   
+   var defaultIpAddress = "ws://";
+   let ws = webSocket.createWebSocket();

 # Sensor Overview
 
 
-Sensors in OpenHarmony are an abstraction of underlying hardware-based sensors. Your application can access the underlying sensors via the sensors. Using the APIs provided by sensors, you can query sensors on your device, subscribe to sensor data, customize algorithms based on sensor data, and develop various sensor-based applications, such as compass, fitness and health, and games applications.
+Sensors in OpenHarmony are an abstraction of underlying sensor hardware. Your application can access the underlying sensor hardware via the sensors. Using the APIs provided by sensors, you can query sensors on your device, subscribe to sensor data, customize algorithms based on sensor data, and develop various sensor-based applications, such as compass, motion-controlled games, and fitness and health applications.
 
 
 A sensor is a device to detect events or changes in an environment and send messages about the events or changes to another device (for example, a CPU). Generally, a sensor is composed of sensitive components and conversion components. Sensors are the cornerstone of the IoT. A unified sensor management framework is required to achieve data sensing at a low latency and low power consumption, thereby keeping up with requirements of "1+8+N" products or business in the Seamless AI Life Strategy. The sensor list is as follows:
