ccc1.5.2热更新获取字节进度不准确。。

[tianyi2010]

log信息如下：
Simulator: JS Custom Version Compare: version A is 0.0.1, version B is 1.0.0
Simulator: event.getDownloadedBytes() / event.getTotalBytes() =0 / 0
Simulator: JS Custom Version Compare: version A is 0.0.1, version B is 1.0.0
Simulator: event.getDownloadedBytes() / event.getTotalBytes() =0 / 0
Simulator: Verification passed : src/jsb_polyfill.jsc (3b7f66ec05955f0bb8393843887d663a)
Simulator: event.getDownloadedBytes() / event.getTotalBytes() =0 / 1570266
Simulator: 更新完成~

项目中使用发现使用字节进度不准确，这个是我为了简单明了故意只下载一个文件的例子，log发现event.getDownloadedBytes() 还是0，就突然完成更新了，实际项目中会有进度，但是也就走到50%左右，然后突然完成了。求大神解答~

你的 manifest 中有没有提供 size 信息？没有的话，是依赖下载过程中返回的信息来判断 total bytes 的，如果是单个文件有可能这个文件确实是很快就下载完成了。

项目中，还是建议提供 size 信息，这样就不依赖请求回来的信息了，而是直接就可以算出总的 total bytes

[tianyi2010]

manifest里是有size信息的，我这个只是为了简单看log才故意弄成一个文件，在实际项目中也是有跳进度的问题，manifes如下：
{“packageUrl”:“http://192.168.1.155/dt",“remoteManifestUrl”:“http://192.168.1.155/dt/project.manifest”,“remoteVersionUrl”:“http://192.168.1.155/dt/version.manifest”,“version”:“1.0.0”,“assets”:{“src/jsb_anysdk.jsc”:{“size”:9897,“md5”:“786252fd7935cb117a640bca348ed8aa”},“src/jsb_anysdk_constants.jsc”:{“size”:6976,“md5”:“4afd432280a7a2c16e7f6e20f2aaa739”},“src/jsb_polyfill.jsc”:{“size”:1570269,“md5”:“229a6b9c7e90674fdde9fb8d7f81e6ff”},“src/project.jsc”:{“size”:14869,“md5”:“9efe352fab889856b8dad61001179e3f”},“src/settings.jsc”:{“size”:836,“md5”:“23de02abadf35b0f7687e3b52816932f”},“res/import/2d/2d2f792f-a40c-49bb-a189-ed176a246e49.json”:{“size”:1842,“md5”:“bc0858b4231db31ff0fc99bbe78a99de”},“res/import/31/31bc895a-c003-4566-a9f3-2e54ae1c17dc.json”:{“size”:171,“md5”:“0e8e9e67cc5353d7929b794d32d27adc”},“res/import/41/410fb916-8721-4663-bab8-34397391ace7.json”:{“size”:164,“md5”:“1e2d427cffc40569124cba36b8675086”},“res/raw-assets/Texture/HelloWorld.png”:{“size”:37864,“md5”:“d0d038ddeb63ef9800e6afc66105a49a”},“res/raw-assets/Texture/singleColor.png”:{“size”:17197,“md5”:“5db1eca7213a22613f5928ea2f8e85e1”}},"searchPaths”:[]}

你使用什么事件来更新进度的？

[tianyi2010]

使用的这个 ：
case jsb.EventAssetsManager.UPDATE_PROGRESSION://5 最新进展 做 进度的
cc.log(“event.getDownloadedBytes() / event.getTotalBytes() =” + event.getDownloadedBytes() + ’ / ’ + event.getTotalBytes());
this._updateCallback(event.getPercent());
break;

马赛克～

麻烦把真实项目里面的 log 发出来看看，我也有点不理解，我们的测试例里面的 byte 信息是正常的

这是 Android 平台把？

[tianyi2010]

我这个是在creator 的模拟器环境运行的，win10.

呃，不建议用模拟器跑热更新项目，不过我会尝试一下
