用于 UnityWebRequest 的 helper 对象。管理 HTTP 请求期间主体数据的缓冲和传输。
附加到 UnityWebRequest 后,UploadHandler 对象在 HTTP 请求期间会处理与主体数据缓冲及传输有关的所有信息。通过将数据放置在 UploadHandler 上并将此对象附加到 UnityWebRequest,隐式指示 UnityWebRequest 将 UploadHandler 的数据传输至远程服务器。此数据将始终作为 HTTP 请求主体数据传递。
UploadHandler 是一个基类,不能直接实例化。目前,仅一种类型的 Upload Handler 可用:UploadHandlerRaw。
另请参阅:UnityWebRequest、UploadHandlerRaw。
contentType | 确定将使用出站 HTTP 请求传输的默认 Content-Type 标头。 |
data | 将作为主体数据传输到远程服务器的原始数据。(只读) |
progress | 返回上传到远程服务器的数据在上传的数据总量中占的比例。(只读) |
Dispose | 表示不再使用此 UploadHandler,并且应清理它使用的所有资源。 |
