可以在 `AppUpdateService` 中添加一个方法,记录每个版本的下载次数,例如:
```
public void recordDownload(String version) {
// TODO: 将版本号为 version 的下载次数加一,可以使用 Redis 或数据库实现计数器
}
```
然后在 `appUpdate` 方法中,在设置下载链接之前调用该方法来记录下载次数,例如:
```
if (downloadUrlStatus) {
String downloadUrlS3 = SpringUtil.getProperty(MessageFormat.format("{0}.s3.download.url", platform.name().toLowerCase()));
log.info("appUpdate downloadUrlS3 {}", downloadUrlS3);
appUpdateResponseVo.setDownloadUrl(downloadUrlS3);
appUpdateService.recordDownload(appUpdateResponseVo.getVersion());
}
```
这样就可以在下载链接被返回时记录下载次数了。同时,可以在 `recordDownload` 方法中添加一些逻辑来限制下载次数,例如:
```
public void recordDownload(String version) {
// TODO: 将版本号为 version 的下载次数加一,可以使用 Redis 或数据库实现计数器
int downloadCount = getDownloadCount(version);
if (downloadCount >= MAX_DOWNLOAD_COUNT) {
throw new RuntimeException("该版本下载次数已达上限");
}
}
```
这样就实现了一个简单的下载次数限制功能。
