cocos creator 3.3 加载bundle本地已经有了，每次还是会发送http请求，状态码是304也就是资源状态没有变化。加载资源还是比较慢？为什么用了缓存中的资源，还要http请求。
是用的不对吗？
我是直接从bundle.load资源，然后再次进入的时候还是回去加载，第一次下载可以理解，第二次还是发送了 http请求，内网，速度没有快多少。
贴下你的加载代码，是加载什么资源了？我们确认下。
public async preloadBundlePrefab(formName:string){
let data = this.splitFormName(formName);
let bundleName = data.bundle;
let prefabName = data.prefabName;
if(this.loadPrefabWithBundleKey.has(bundleName) && this.loadPrefabWithBundleKey.get(bundleName)?.has(formName)){
this.loadProgress[formName] = 1;
this.calProgress(2);
return;
}
let bundle = this.subGameBundle.get(bundleName);
if (bundle == undefined){
console.error(`${bundleName}不存在`);
return;
}
if (!this.loadPrefabWithBundleKey.has(bundleName)){
this.loadPrefabWithBundleKey.set(bundleName,new Map<string,Prefab>());
}
bundle!.load<Prefab>(prefabName,(loadCnt:number,allCnt:number,item:AssetManager.RequestItem)=>{
this.loadProgress[formName] = loadCnt/allCnt;
this.calProgress(0);
},(err,prefab:Prefab)=>{
if (err != null){
console.log(err);
console.warn(`${formName}加载失败`);
}else{
console.log(`${formName}加载成功`);
this.loadProgress[formName] = 1;
if (!this.loadPrefabWithBundleKey.has(bundleName)){
this.loadPrefabWithBundleKey.set(bundleName,new Map<string,Prefab>());
}
this.loadPrefabWithBundleKey.get(bundleName)!.set(formName,prefab);
this.loadPrefabWithBundleKey.get(bundleName)!.get(formName)!.addRef();
this.calProgress(1);
}
});
}
首次请求的话 状态码是 200
这个问题是怎么回事？是我用的有问题吗？
可以私信给我个demo吗？这个正常是会从缓存加载的，需要排查下。
好。我现在去准备。
正常情况下从缓存中去，是不是就不会发送http请求了？
另外浏览器是不是有什么设置？
public releaseAllResByList(list:Map<string,number>){
let bName = "";
for (let key of list.keys()){
let resData = this.splitFormName(key);
let bundleName = resData.bundle;
bName =bundleName;
if(list.get(key) == ResType.ResType_SpriteFrame){
if (!this.loadSpriteFrameWithBundleKey.has(bundleName)){
continue;
}
if (!this.loadSpriteFrameWithBundleKey.get(bName)!.has(key)){
continue;
}
while(this.loadSpriteFrameWithBundleKey.get(bName)!.get(key)!.refCount >0) {
this.loadSpriteFrameWithBundleKey.get(bName)!.get(key)!.decRef();
}
this.loadSpriteFrameWithBundleKey.get(bName)!.delete(key);
}else if(list.get(key) == ResType.ResType_SpriteAtlas){
//释放图集资源
if(!this.loadSpriteAtlasWithBundleKey.has(bundleName)){
continue;
}
if(!this.loadSpriteAtlasWithBundleKey.get(bName)!.has(key)){
continue;
}
while(this.loadSpriteAtlasWithBundleKey.get(bName)!.get(key)!.refCount >0) {
this.loadSpriteAtlasWithBundleKey.get(bName)!.get(key)!.decRef();
}
this.loadSpriteAtlasWithBundleKey.get(bName)!.delete(key);
}else if(list.get(key) == ResType.ResType_Prefab){
//预制体资源
if(!this.loadPrefabWithBundleKey.has(bundleName)){
continue;
}
if(!this.loadPrefabWithBundleKey.get(bName)!.has(key)){
continue;
}
while(this.loadPrefabWithBundleKey.get(bName)!.get(key)!.refCount >0) {
this.loadPrefabWithBundleKey.get(bName)!.get(key)!.decRef();
}
this.loadPrefabWithBundleKey.get(bName)!.delete(key);
}else if(list.get(key) == ResType.ResType_AudioClip){
//音频资源
if(!this.loadAudioClipWithBundleKey.has(bundleName)){
continue;
}
bName = bundleName;
if(!this.loadAudioClipWithBundleKey.get(bName)!.has(key)){
continue;
}
while(this.loadAudioClipWithBundleKey.get(bName)!.get(key)!.refCount >0) {
this.loadAudioClipWithBundleKey.get(bName)!.get(key)!.decRef();
}
this.loadAudioClipWithBundleKey.get(bName)!.delete(key);
}
}
if (bName != "" ) {
this.loadPrefabWithBundleKey.delete(bName);
this.loadAudioClipWithBundleKey.delete(bName);
this.loadSpriteFrameWithBundleKey.delete(bName);
this.loadSpriteAtlasWithBundleKey.delete(bName);
// if(this.subGameBundle.has(bName)){
// this.subGameBundle.delete(bName);
// }
//调用了 releaseAll 应该不需要再 desRef() 方法了。源码中tryRelease就是将
//这里releaaseAll还不能调用，如果调用，第二次加载sprite的时候还是有问题的。 暂时不调用，但是回头要处理一下
//需要调用releaseAll否则有的资源释放不掉
//assetManager.getBundle(bName)!.releaseAll();
//assetManager.removeBundle(assetManager.getBundle(bName)!);
console.log("releaseAll执行了-----",bName);
}上面是我加载bundle和离开bundle的时候释放资源的方法。你先看一下有没有问题。没有removeBundle。但是里边的资源释放了。

如果你释放了资源，可能会触发重新下载不存在的资源，304 是从浏览器本地缓存加载资源，只是减少网络传输的时间损耗，资源解析正常执行，实际还是要看你的资源使用情况。
