## Description
|
||
|
||
`batch-requests` can accept multiple request and send them from `apisix` via [http pipeline](https://en.wikipedia.org/wiki/HTTP_pipelining), 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

## Test Plugin
|
||
|
||
You can pass your request detail to batch API( `/apisix/batch-requests` ), `apisix` can automatically complete requests via [http pipeline](https://en.wikipedia.org/wiki/HTTP_pipelining). Such as:
|
||
```shell
|
||
curl --location --request POST 'http://127.0.0.1:9080/apisix/batch-requests' \
|
||
--header 'Content-Type: application/json' \
|
||
--d '{
|
||
"headers": {
|
||
"Content-Type": "application/json",
|
||
"admin-jwt":"xxxx"
|
||
},
|
||
"timeout": 500,
|
||
"pipeline": [
|
||
{
|
||
"method": "POST",
|
||
"path": "/community.GiftSrv/GetGifts",
|
||
"body": "test"
|
||
},
|
||
{
|
||
"method": "POST",
|
||
"path": "/community.GiftSrv/GetGifts",
|
||
"body": "test2"
|
||
}
|
||
]
|
||
}'
|
||
```
|
||
|
||
response as below：
|
||
```json
|
||
[
|
||
{
|
||
"status": 200,
|
||
"reason": "OK",
|
||
"body": "{\"ret\":500,\"msg\":\"error\",\"game_info\":null,\"gift\":[],\"to_gets\":0,\"get_all_msg\":\"\"}",
