	 * 示例
	 */
	public void example() {
		String key = "key";
		String value = "value";
		String lockKey = "lockKey";
		long lockTimeout = 3600L;
		
		// 设置值
		redis.set(key, value);
		// 获得值
		redis.get(key);
		// 删除值
		redis.del(key);
		// 分布式锁-加锁
		redis.lock(lockKey, lockTimeout);
		// 分布式锁-解锁
		redis.unlock(lockKey, lockTimeout);
	}

### Setting Linux Network Proxy Environment Variables

Source: https://github.com/yl-yue/yue-library/blob/master/docs/base/网络代理.md

Configure proxy settings by exporting environment variables. `all_proxy` sets a global proxy, while `no_proxy` specifies hosts that should bypass the proxy. This example demonstrates setting a proxy and then defining local and remote hosts to exclude.

```bash
vi /etc/profile

export all_proxy=192.168.0.2:3128 # 代理服务器地址及认证信息

no_proxy_local=localhost,127.0.0.1,0.0.0.0,10.0.0.0/8
no_proxy_1=192.168.3.1
no_proxy_2=$(echo 192.168.0.{65..69} | sed 's/ /,/g')
no_proxy_3=$(echo 10.15.65.{90..110} | sed 's/ /,/g')

export no_proxy=${no_proxy_local},${no_proxy_1},${no_proxy_2},${no_proxy_3} # 不需要代理的IP

source /etc/profile && curl www.baidu.com
```

### JetCache Batch API Usage Example

Source: https://github.com/yl-yue/yue-library/blob/master/docs/data/redis/二级缓存.md

Demonstrates using JetCache batch operations to retrieve, update, and store multiple cache entries. It checks if all requested keys are present in the cache and fetches missing data from the database, then updates the cache.

```java
public Result<?> getCacheBatch(Set<Long> ids) {
    // 查询缓存
    Map<Long, TableExampleStandard> all = cacheTest.getAll(ids);

    if (all.size() != ids.size()) {
        System.out.println("未命中Redis缓存，使用JDBC去数据库查询数据。");
        // 查询数据库
        List<TableExampleStandard> list = tableExampleService.listByIds(ids);
        for (TableExampleStandard tableExampleStandard : list) {
            all.put(tableExampleStandard.getId(), tableExampleStandard);
        }

        // 设置缓存
        cacheTest.putAll(all);
    }

    return R.success(all);
}
```

```java
@PostMapping
public Result<?> post(String v1, int v2, boolean v3, v4 v5 ...)
```

--------------------------------

### Get Symmetric Key API

Source: https://github.com/yl-yue/yue-library/blob/master/docs/base-crypto/密钥交换加解密.md

This section describes the API endpoint for obtaining a symmetric encryption key. It includes a JavaScript example for making the request and scripts for pre-processing (generating RSA keys) and post-processing (decrypting the AES key).

```APIDOC
## POST /open/v2.6/keyExchange/getSymmetricKey

### Description
This endpoint is used by the client to obtain a symmetric encryption key (AES key) from the server. The request involves exchanging RSA public keys to securely transmit the AES key.

### Method
POST

### Endpoint
/open/v2.6/keyExchange/getSymmetricKey

### Parameters
#### Request Body
- **sessionKey** (string) - Required - Session key for authentication.
- **exchangeKeyType** (string) - Required - Specifies the key exchange type, e.g., "RSA_AES".
- **clientPublicKey** (string) - Required - The client's public RSA key in Base64 format.

### Request Example
```js
var formdata = new FormData();
formdata.append("sessionKey", "3af180d408e04d3fb6a6df4cad95c78d");
formdata.append("exchangeKeyType", "RSA_AES");
formdata.append("clientPublicKey", "{{publicKeyBase64}}");

var requestOptions = {
   method: 'POST',
   body: formdata,
   redirect: 'follow'
};

fetch("localhost:8080/open/v2.6/keyExchange/getSymmetricKey", requestOptions)
   .then(response => response.text())
   .then(result => console.log(result))
   .catch(error => console.log('error', error));
```

### Pre-processing Script (Generate RSA Keys)
This script generates an RSA key pair and extracts the public key in Base64 format for use in the API request.

```js
const rsa = require('jsrsasign');
// Generate RSA key pair
var keypair = rsa.KEYUTIL.generateKeypair("RSA", 1024);
const publicKeyPEM = rsa.KEYUTIL.getPEM(keypair.pubKeyObj);
const privateKeyPEM = rsa.KEYUTIL.getPEM(keypair.prvKeyObj, "PKCS8PRV");

// Remove PEM identifiers and newlines
const publicKeyBase64 = publicKeyPEM
  .replace(/-----BEGIN PUBLIC KEY-----/g, '')  // Remove start identifier
  .replace(/-----END PUBLIC KEY-----/g, '')    // Remove end identifier
  .replace(/\s+/g, '');                        // Remove all whitespace characters, including newlines

console.log("Public Key:", publicKeyBase64);
console.log("Private Key:", privateKeyPEM);

pm.variables.set("publicKeyBase64", publicKeyBase64);
pm.variables.set("privateKeyPEM", privateKeyPEM);
```

### Post-processing Script (Decrypt AES Key)
This script uses the generated RSA private key to decrypt the symmetric key returned by the server.

```js
const rsa = require('jsrsasign');

// Get RSA private key
const privateKeyPEM = pm.variables.get("privateKeyPEM");

// Decrypt with private key
var encryptedBase64 = pm.response.json().data.clientPublicKeyEncryptSymmetricKey;
const decryptedHex = rsa.b64tohex(encryptedBase64);  // Decode Base64 to Hex
console.log(decryptedHex);
const prvKeyObj = rsa.KEYUTIL.getKey(privateKeyPEM);
const decrypted = rsa.KJUR.crypto.Cipher.decrypt(decryptedHex, prvKeyObj);
console.log("Decrypted Plaintext:", decrypted);
var json = pm.response.json();
json.data.aesKey = decrypted;
pm.response.setBody(json);
```

### Response
#### Success Response (200)
- **code** (integer) - Response status code, 200 indicates success.
- **msg** (string) - Success message.
- **flag** (boolean) - Indicates if the operation was successful.
- **traceId** (string) - Trace ID for debugging.
- **data** (object) - Contains encryption details.
  - **enabled** (boolean) - Indicates if encryption is enabled.
  - **clientPublicKeyEncryptSymmetricKey** (string) - The symmetric key encrypted with the client's public RSA key.
