Compress

Compression middleware for Fiber that will compress the response using gzip, deflate and brotli compression depending on the Accept-Encoding header.

​ 用于 Fiber 的压缩中间件，它将使用 gzip 、 deflate 和 brotli 压缩来压缩响应，具体取决于 Accept-Encoding 标头。

NOTE 注意

The compression middleware refrains from compressing bodies that are smaller than 200 bytes. This decision is based on the observation that, in such cases, the compressed size is likely to exceed the original size, making compression inefficient. more

​ 压缩中间件不会压缩小于 200 字节的主体。此决定基于以下观察：在这种情况下，压缩后的尺寸很可能超过原始尺寸，从而使压缩效率低下。更多

Config 配置

Possible values for the “Level” field are:

​ “级别”字段的可能值为：

• LevelDisabled (-1): Compression is disabled. LevelDisabled (-1) ：禁用压缩。
• LevelDefault (0): Default compression level. LevelDefault (0) ：默认压缩级别。
• LevelBestSpeed (1): Best compression speed. LevelBestSpeed (1) ：最佳压缩速度。
• LevelBestCompression (2): Best compression. LevelBestCompression (2) ：最佳压缩。
