Summary

Description

batch-requests can accept multiple request and send them from apisix via http pipeline, and return an aggregated response to client, which can significantly improve performance when the client needs to access multiple APIs.

Tips

The HTTP headers for the outer batch request, except for the Content- headers such as Content-Type, apply to every request in the batch. If you specify a given HTTP header in both the outer request and the individual call, the header's value of individual call would override the outer batch request header's value. The headers for an individual call apply only to that call.

Attributes

None

API

--header 'Content-Type: application/json' \
--data '{
    "headers": {
