You start a download in the background by calling WWW(url) which returns a new WWW object.

你通过连接WWW(url)在后台开始下载，并且返回一个新的WWW对象。

You can inspect the isDone property to see if the download has completed or yield the download object to automatically wait until it is (without blocking the rest of the game).

你可以检查isDone属性来查看是否已经下载完成，或者yield自动等待下载物体，直到它被下载完成（不会影响游戏的其余部分）。

Use it if you want to get some data from a web server for integration with a game such as highscore lists or calling home for some reason. There is also functionality to create textures from images downloaded from the web and to stream & load new web player data files.

如果你想从web服务器上获取一些数据，例如高分列表或者调用主页，可以使用这个，也有一些功能可以使用从web上下载的图片来创建一个纹理，或者下载或加载新的web播放器数据文件。

The WWW class can be used to send both GET and POST requests to the server. The WWW class will use GET by default and POST if you supply a postData parameter.

WWW类可以用来发送GET和POST请求到服务器，WWW类默认使用GET方法，并且如果提供一个postData参数可用POST方法。

See Also: WWWForm for a way to build valid form data for the postData parameter.

参见: WWWForm为postData参数构建可用的表单数据。

Note: URLs passed to WWW class must be '%' escaped.

注意，URL传递到WWW类，必须是%编码。

Note: http://, https:// and file:// protocols are supported on iPhone. ftp:// protocol support is limited to anonymous downloads only. Other protocols are not supported.

注意：iPhone支持http://， https:// 和 file://协议；ftp://协议的支持仅限于匿名下载。其他协议不被支持。

''Note:'' When using file protocol on Windows and Windows Store Apps for accessing local files, you have to specify file:///__ (with three slashes).

注意，当在windows和Windows Store Apps使用文件协议来访问本地文件，需要使用file:///（带有三个斜线）。

Note: The security sandbox present in web-player builds prevents you from accessing content not hosted the server where the webplayer is hosted.

注意：在当前的web播放器构建安全沙箱防止你访问内容没有托管服务器，在哪里web播放器被托管。
