For the HTTP protocol, compressing the response data can reduce the amount of data transferred, thereby shortening response time, saving server bandwidth, and improving client performance.
This task guides you on how to compress a response through API Gateway.
Interaction Process
Operation Description
By default, API Gateway supports response compression based on the GZIP compression algorithm. To implement this feature, the following requirements need to be met:
The client request contains the Accept-Encoding header and its value contains gzip.
The response body size of the client is greater than 1 KB.
Content-Type of the response body is text/xml, text/plain, text/css, application/javascript, application/x-javascript, application/rss+xml, application/xml, application/json, or application/octet-stream.
If the client request meets the requirements above, API Gateway will return the compressed response body to the client and contain the Content-Encoding: gzip header in the response.
Notes
Response compression supports only the HTTP and HTTPS protocols but not WebSocket.
If the backend is connected to SCF and response integration is enabled, the structure that SCF returns to API Gateway cannot contain the Content-Encoding: gzip header. Otherwise, response compression will not take effect.
