FirstCatchYourHare opened a new issue, #11356:
URL: https://github.com/apache/apisix/issues/11356
### Current Behavior
When I turn on kafka-logger and body-transformer at the same time, the
response body conversion of body-transformer plugin will fail. After turning
off kafka-logger, body-transformer plug-in will fail
### Expected Behavior
I hope that when I turn on kafka-logger and body-transformer at the same
time, both will work properly at the same time
### Error Logs
When I turn on kafka-logger and body-transformer at the same time,By
tracking the source code log,I found that when the body-transformer plugin
code went to body_filter, it got an empty response table, so the conversion
failed, but the request was still successful, but no response body was returned
function _M.body_filter(_, ctx)
local conf = ctx.body_transformer_conf
if conf.response then
local body = core.response.hold_body_chunk(ctx)
core.log.error(cjson.encode(body))
if ngx.arg[2] == false and not body then
return
end
local out = transform(conf, body, "response", ctx)
if not out then
core.log.error("failed to transform response body: ", body)
return
end
ngx.arg[1] = out
end
end
### Steps to Reproduce
1.Enable plug-ins kafka-logger and body-transformer at the same time
2.The upstream service is a webservice
3.By configuring body-transformer, you mainly convert the xml response body
to the json response body
