[Bug]：Can not aquire the specific config

[robocanic]

Describe the bug

environments:

• java version: corretto 21
• nacos sdk/client version: 2.3.2
• nacos deployment mode: standalone, windows10 PC

I start a dubbo service on local PC(the code of this dubbo service comes from the dubbo-samples), using nacos client 2.2.0. And it works fine, the service registered and I can find the config and service info through the console:

Following the "quick start" of the official website , I want to get the config content of "dataId=org.apache.dubbo.samples.UserService:::provider:shop-user, group=dubbo" as below:

public class NacosApplication {
    public static void main(String[] args) {
        String content;
        try {
            String serverAddr = "localhost:8848";
            String dataId = "org.apache.dubbo.samples.UserService:::provider:shop-user";
            String group = "dubbo";
            Properties properties = new Properties();
            properties.put("serverAddr", serverAddr);
            ConfigService configService = NacosFactory.createConfigService(properties);
            content = configService.getConfig(dataId, group, 5000);
            System.out.println("content is:"+content);
        } catch (NacosException e) {
            e.printStackTrace();
        }
    }
}

The expected result config content should be : But it returns null:

Then I change the dataId and group to try to aquire another config content:

public class NacosApplication {
    public static void main(String[] args) {
        String content;
        try {
            String serverAddr = "localhost:8848";
            String dataId = "org.apache.dubbo.samples.UserService";
            String group = "mapping";
            Properties properties = new Properties();
            properties.put("serverAddr", serverAddr);
            ConfigService configService = NacosFactory.createConfigService(properties);
            content = configService.getConfig(dataId, group, 5000);
            System.out.println("content is:"+content);
        } catch (NacosException e) {
            e.printStackTrace();
        }
    }
}

It works fine just as below, which is really wired:

I have confirmed that the dataId and group is the same as the console shows, I have no idea for this bug, can someone tell me where the problem lies?

你好，麻烦将不可用的配置内容，dataId和group发一下，我复现下看看

我用jdk8和jdk21都没有复现出来，客户端debug看下请求 服务端看下config-pull-check.log，或者配置nacos.plugin.datasource.log.enabled=true看下sql对不对

[robocanic]

debug:

config-dump.log

config-pull-check.log

看起来是server端有些问题

[985492783]

看样子是client获取到数据后保存快照的时候报错了，文件名特殊符号不支持

[KomachiSion]

新版本应该在写缓存的时候有进行encode的，是否是系统版本读取的时候没读取正确？

可以看下 PathEncode 和PathEncodeManager是否没有用上或者读取错误导致没有识别到用Windows的PathEncode

[KomachiSion]

#10101

[KomachiSion]

com.alibaba.nacos.config.server.service.dump.disk.ConfigRawDiskService

DiskUtil被迁移到了这个上面，但是丢失了#10101中的encode修复

[robocanic]

这个问题在哪些版本中存在？
