1. Import the **http** namespace from **@ohos.net.http.d.ts**.
2. Call **createHttp()** to create an **HttpRequest** object.
3. Call **httpRequest.on()** to subscribe to HTTP response header events. This API returns a response earlier than the request. You can subscribe to HTTP response header events based on service requirements.
4. Call **httpRequest.request()** to initiate a network request. You need to pass in the URL and optional parameters of the HTTP request.
5. Parse the returned result based on service requirements.
6. Call **off()** to unsubscribe from HTTP response header events.
7. Call **httpRequest.destroy()** to release resources after the request is processed.

# Socket Connection
## Introduction
## Use Cases
The Socket Connection module allows an application to transmit data over a Socket connection through the TCP, UDP, or TLS protocol.
Your application can transmit data through Socket connections. Currently, the TCP and UDP protocols are supported.
## Basic Concepts
- Socket: An abstraction of endpoints for bidirectional communication between application processes running on different hosts in a network.
- TCP: Transmission Control Protocol, which is a byte stream–based transport layer communication protocol that is connection-oriented and reliable.
- UDP: User Datagram Protocol, which is a simple datagram-oriented transport layer communication protocol.
- TLS: Transport Layer Security, which is a protocol that ensures the data confidentiality and integrity between communication programs.
## When to Use
Applications transmit data over TCP, UDP, or TLS Socket connections. The main application scenarios are as follows:
- Implementing data transmission over TCP/UDP Socket connections
- Implementing encrypted data transmission over TLS Socket connections
## Available APIs
The Socket connection function is mainly implemented by the Socket module. The following table describes the related APIs.
For the complete list of APIs and example code, see [Socket Connection](../reference/apis/js-apis-socket.md).

1. Import the required **socket** module.
2. Bind the IP address and port number of the server.

4. Create a **TLSSocket** object.
5. (Optional) Subscribe to TLS Socket connection events.
6. Send data.
