包路径：org.simpleframework.http.Response
类名称：Response
方法名：setContentLength

Response.setContentLength介绍

[英]This should be used when the size of the message body is known. This ensures that Persistent HTTP (PHTTP) connections can be maintained for both HTTP/1.0 and HTTP/1.1 clients. If the length of the output is not known HTTP/1.0 clients will require a connection close, which reduces performance (see RFC 2616).

This removes any previous Content-Length headers from the message header. This will then set the appropriate Content-Length header with the correct length. If a the Connection header is set with the close token then the semantics of the connection are such that the server will close it once the output stream or request is closed.
[中]当消息正文的大小已知时，应使用此选项。这确保了HTTP/1.0和HTTP/1.1客户端都可以保持持久HTTP（PHTTP）连接。如果输出的长度未知，HTTP/1.0客户端将需要关闭连接，这会降低性能（请参阅RFC 2616）。
这将从消息头中删除任何以前的内容长度头。然后，这将使用正确的长度设置适当的内容长度标题。如果使用close标记设置了连接头，那么连接的语义是，一旦输出流或请求关闭，服务器就会关闭它。
