dcc更新失效, 有代码, 100%复现, 三楼附临时解决办法

Laya用户

用附件里与cdn上的dcc描述文件, 可以发现 version.json hash已经发生变化
对应的缓存名叫 fe0aee13
然后我们进入游戏,
从log能看出, assetsid.txt下载成功, 并且对比assetsid不一致, 继续下载filetable.bin
再往下走执行bundle后加载的第一个文件就是 version.json,
此时并未按照dcc更新的规则去下载新的文件, 而是直接从缓存里读取了旧文件
是我姿势不对?

补充一个细节, 5月14日测试的时候一切正常, 似乎是之后才出现的问题.

我这边用新版测试的话，结果是对的，日志也比较全

xhr.get url=http://cdn.odds5.com/bmh5/testLayaDcc2/version.json
found the file in the package:fe0aee13

Erorr! _loadFromAssets returns incorrect contents! what happened!

Download [  ]:http://cdn.odds5.com/bmh5/testLayaDcc2/version.json?316b5c32

有一步是从缓存取，但是会发现dcc不对，所以会重新下载。

你打印一下看看实际文件内容是否是正确的。会不会只是打印的问题。
如果升级容易，可以升级看看。

Laya用户

郭兆奎请问新版测试是哪个版本?
我这用的是 LayaNative-Release-2.1.0
早上又测了下, 文件内容确实没发生变化, 确认是缓存里的旧数据

郭兆奎 @Laya用户:引擎和native都用2.1.0

郭兆奎 @Aar0n:引擎 Native ide都换了重出一次,还是不行

郭兆奎补充一个细节, 5月14日测试的时候一切正常, 似乎是之后才出现的问题.

对于大家都普遍弱逼的情况下, 我只好无奈的弄了个临时的解决办法.
1.从layaconch.jar里的index.js取出index.js拷贝到assets\scripts下面, 程序会优先读取assets\scripts\index.js
此时可以魔改一下[code] if (_inline) {

            yield updateDcc();
            if (!isDccOk) {
                console.log("init dcc fail");
                return;
            }
        }
        if( !(yield dj_hook.OnDccOk()) )
        {
            if (window["onLayaInitError"]) {
                window["onLayaInitError"]("Update index error");
            }
            return;
        }
        var data = yield asyncs.loadText(url);
        for (var n = 0; n < 3 && !data; n++) {
            data = yield asyncs.loadText(url);
        }[/code]2.使用ide的版本管理, 参与版本管理的文件, 因为文件名变了, 所以dcc更新策略有效

3. 第2条中, http://xxx/index.js 与 version.json 因为文件名不会变, 所以需要手动处理下
在 dj_hook.OnDccOk 里强制从cdn下载两个文件, 然后使用 window.appcache.updateFile 强制刷新缓存

如果没出错, 那之后就一切正常了

Laya用户这个靠谱，已经搞定了，非常感谢乐意分享的同学！

Laya用户 dj_hook 是个啥。全局看完都没看懂这个

Laya用户

Laya用户 @王壮壮:dj_hook是具体的代码实现, 懂的人自然会写

karin666

郭兆奎 @Aar0n:不行的

karin666

请问解决了吗？我也遇到这个问题，求解决！

Laya用户

@karin666:目前还没解决

Laya用户

@karin666:可以参考三楼的临时解决办法

所有文件都有这个问题，updateFile没有意义吧（那还不如自己做版本管理，本来自己做最好，官方要定一个dcc流程），这个应该是官方判断新的hash值的时候有问题导致始终用的缓存的
