文字

TE请求报头指定传输编码的用户代理是愿意接受。（你可以非正式地称它Accept-Transfer-Encoding，这会更直观）。

有关Transfer-Encoding传输编码的更多详细信息，另请参阅响应头。请注意，chunked HTTP / 1.1 收件人始终可以接受，而您不必"chunked"使用TE标头指定。但是，对于设置客户端是否正在使用“预告片”值接受分块传输编码中的预告片字段很有用。

Header type	Request header
Forbidden header name	yes

句法

TE: compress
TE: deflate
TE: gzip
TE: trailers// Multiple directives, weighted with the quality value syntax:TE: trailers, deflate;q=0.5

指令

compress使用 Lempel-Ziv-Welch （LZW）算法的格式被接受为传输编码名称。deflate使用 zlib 结构被接受为传输编码名称。gzip使用带有32位 CRC 的 Lempel-Ziv编码（LZ77）的格式被接受为传输编码名称。追加表示客户愿意接受分块传输编码中的尾部字段 .q

当多个传输编码可接受时，质量值语法的q参数可以优先排列编码。
