使用originalContent需要导入什么java包 写出代码

要使用`originalContent`并涉及到HTTP请求和可能的AES-128-CBC解密，你需要导入以下Java包：

1. 对于HTTP请求的支持（如Apache HttpClient）[^1]:

import org.apache.http.HttpEntity;
import org.apache.http.client.methods.CloseableHttpResponse;
import org.apache.http.client.methods.HttpGet;
import org.apache.http.impl.client.CloseableHttpClient;
import org.apache.http.impl.client.HttpClients;
import org.apache.http.util.EntityUtils;

2. 如果涉及到了微信AES-128-CBC解密，还需要这些包:

import org.bouncycastle.jce.provider.BouncyCastleProvider;
import org.apache.commons.codec.binary.Base64;
import org.apache.commons.lang3.StringUtils;
import org.codehaus.xfire.security.token.AES128CBCToken;
import org.codehaus.xfire.security.token.TokenException;

下面是一个简单的示例，展示如何使用这些包来发送GET请求并尝试解密原始内容，假设`encryptedContent`已经包含了加密后的数据：

// 加载BouncyCastle库
Security.addProvider(new BouncyCastleProvider());

CloseableHttpClient httpClient = HttpClients.createDefault();

// 发起HTTPS GET请求
HttpGet httpGet = new HttpGet("https://example.com/your-endpoint");
CloseableHttpResponse response = httpClient.execute(httpGet);

try {
    HttpEntity entity = response.getEntity();
    String encryptedContent = EntityUtils.toString(entity); // 假设从响应体获取到

    // 假设有一个解密函数，它接受加密内容和密钥
    byte[] decryptedBytes = decryptAES128CBC(encryptedContent, "your-secret-key"); // 请替换实际密钥

    String originalContent = new String(decryptedBytes);
    System.out.println("Original content: " + originalContent);
} catch (Exception e) {
    e.printStackTrace();
} finally {
    try {
        response.close();
    } catch (IOException e) {
        e.printStackTrace();
    }
}

// 解密函数示例（这里仅用于说明，实际情况需根据具体算法实现）
private byte[] decryptAES128CBC(String encryptedContent, String key) throws Exception {
    AES128CBCToken token = new AES128CBCToken();
    byte[] decodedBase64 = Base64.decodeBase64(encryptedContent);
    if (StringUtils.isBlank(key)) throw new TokenException("Missing decryption key");

    return token.decrypt(decodedBase64, key.getBytes());
}
