```
### Steps to Reproduce
1.Run Apisix 2.15.3 in docker.
2.Config a route like this.
```yaml
uri: /test-send-raw-split
name: test-send-raw-split
plugins:
serverless-pre-function:
functions:
- |
local core = require('apisix.core');
local conf = {
check_result = 'ok',
body_schema = {
properties = {
method = {
pattern = '^(?!aaa|bbb)',
type = 'string'
}
},
required = {'method'},
type = 'object'
}
}
return function(conf, ctx)
core.ctx.register_var("check_result", function(ctx)
local req_body
local body, err = core.request.get_body()
if not body then
if err then
core.log.error("failed to get body: ", err)
end
conf.check_result = "no"
end
local headers = core.request.headers(ctx)
if headers["content-type"] ==
"application/x-www-form-urlencoded" then
-- use 0 to avoid truncated result and keep the behavior as the
-- same as other platforms
req_body, err = ngx.decode_args(body, 0)
else -- JSON as default
req_body, err = core.json.decode(body)
end
if not req_body then
core.log.error('failed to decode the req body: ', err)
conf.check_result = "no"
end
local ok, err = core.schema.check(conf.body_schema, req_body)
if not ok then
core.log.error("req schema validation failed: ", err)
conf.check_result = "no"
end
return conf.check_result
end)
end
phase: rewrite
traffic-split:
rules:
- match:
- vars:
- - check_result
- '=='
- ok
weighted_upstreams:
- upstream:
nodes:
echo-api.3scale.net: 1
type: roundrobin
- match:
- vars:
- - check_result
- '=='
- 'no'
weighted_upstreams:
- upstream:
nodes:
echo-api.3scale.net: 1
type: roundrobin
status: 1
```
3.Use the curl command to request a configured route.
```shell
curl -H "Content-Type: application/json" --data
'{"jsonrpc":"2.0","method":"cccc","params":[],"id":83}'
http://127.0.0.1/test-send-raw-split
```
