用于用户创建的脚本驱动型 DownloadHandler 实现的抽象基类。
DownloadHandlerScript 对象本身不执行任何有意义的操作。
相反,它将从网络中接收的数据转发给 DownloadHandler.ReceiveData 回调方法,还会为下载相关事件调用其他有用回调。默认情况下,DownloadHandlerScript 不执行任何操作;不过,您可以从 DownloadHandlerScript 派生自己的子类,覆盖其部分或全部回调,从而实现完全自定义的数据处理。
另请参阅:DownloadHandler.ReceiveData、DownloadHandler.ReceiveContentLength、DownloadHandler.CompleteContent。
DownloadHandlerScript | 创建可在将数据传递给回调时分配新缓冲区的 DownloadHandlerScript。 |
data | 返回从远程服务器下载的原始字节,或 null。(只读) |
error | Error message describing a failure that occurred inside the download handler. |
isDone | 如果此 DownloadHandler 的父 UnityWebRequest 已通知它已接收所有数据,且此 DownloadHandler 已完成所有必要的下载后处理操作,则返回 true。(只读) |
nativeData | Provides direct access to downloaded data. |
text | 便捷属性。返回解释为 UTF8 字符串的 data 中的字节。(只读) |
Dispose | 表示不再使用此 DownloadHandler,并且应清理它使用的所有资源。 |
CompleteContent | 在从远程服务器接收所有数据后调用的回调。 |
GetData | 访问 data 属性时调用的回调。 |
GetNativeData | Provides allocation-free access to the downloaded data as a NativeArray. |
GetProgress | 访问 UnityWebRequest.downloadProgress 时调用的回调。 |
GetText | 访问 text 属性时调用的回调。 |
ReceiveContentLengthHeader | 在收到 Content-Length 标头调用的回调。 |
ReceiveData | 从远程服务器收到数据时调用的回调。 |
