echo Plugin is to help users understand how they can develop an APISIX Plugin.
This Plugin addresses common functionalities in phases like init, rewrite, access, balancer, header filter, body filter and log.
echo Plugin is built as an example. It has missing cases and should not be used in production environments.
|before_body||string||optional||Body to use before the filter phase.|
|body||string||optional||Body that replaces the Upstream response.|
|after_body||string||optional||Body to use after the modification phase.|
|headers||object||optional||New headers to use for the response.|
At least one of
after_body must be specified.
The example below shows how you can enable the
echo Plugin for a specific Route:
curl http://127.0.0.1:9180/apisix/admin/routes/1 -H 'X-API-KEY: edd1c9f034335f136f87ad84b625c8f1' -X PUT -d '
"before_body": "before the body modification "
First, we configure the Plugin as mentioned above. We can then make a request as shown below:
curl -i http://127.0.0.1:9080/hello
HTTP/1.1 200 OK
before the body modification hello world
To disable the
echo Plugin, you can delete the corresponding JSON configuration from the Plugin configuration. APISIX will automatically reload and you do not have to restart for this to take effect.
curl http://127.0.0.1:9180/apisix/admin/routes/1 \
-H 'X-API-KEY: edd1c9f034335f136f87ad84b625c8f1' -X PUT -d '
