## Chat room interface

There are two ways to connect to a chat room to obtain chat information, each with its own advantages and disadvantages. This article uses the method of `Web API`.

### Websockets

advantage:

1. Do not require a large number of requests and avoid frequent restrictions.

shortcoming:

1. A long connection is required, which is not suitable for most scripting environments.

2. When the connection is good, one or two messages will be lost occasionally (unknown reason).

3. The content needs to be decoded, and the decoding module has to be extracted by reverse JS.

### Web API

advantage:

1. Obtaining data is simple and convenient, without encoding and encryption.

shortcoming:

1. The request limit may be triggered, and the request frequency needs to be strictly controlled.
