如何获取Httpexception的响应体

try {
    // 发起HTTP请求
    HttpResponse response = httpClient.execute(httpRequest);
    
    // 获取响应体
    HttpEntity entity = response.getEntity();
    
    // 判断响应状态码
    int statusCode = response.getStatusLine().getStatusCode();
    if (statusCode == HttpStatus.SC_OK) {
        // 响应成功，处理响应体
        InputStream inputStream = entity.getContent();
        // TODO: 处理响应体的输入流
    } else {
        // 响应失败，处理错误信息
        String errorMessage = EntityUtils.toString(entity);
        // TODO: 处理错误信息
    }
} catch (HttpException e) {
    // 捕获HttpException异常
    HttpResponse response = e.getResponse();
    HttpEntity entity = response.getEntity();
    // TODO: 处理异常响应体
}
