|
|
Here's an example, enable the `response rewrite` plugin on the specified route:
|
|
|
|
```shell
|
|
curl http://127.0.0.1:9080/apisix/admin/routes/1 -X PUT -d '
|
|
{
|
|
"methods": ["GET"],
|
|
"uri": "/test/index.html",
|
|
"plugins": {
|
|
"response-rewrite": {
|
|
"body": "{\"code\":\"ok\",\"message\":\"new json body\"}",
|
|
"headers": {
|
|
"X-Server-id": 3,
|
|
"X-Server-status": "on"
|
|
}
|
|
}
|
|
},
|
|
"upstream": {
|
|
"type": "roundrobin",
|
|
"nodes": {
|
|
"127.0.0.1:80": 1
|
|
}
|
|
}
|
|
}'
|
|
```
|
|
|
|
## Test Plugin
|
|
Testing based on the above examples :
|
|
|
|
```shell
|
|
curl -X GET -i http://127.0.0.1:9080/test/index.html
|
|
```
|
|
|
|
It will output like below,no matter what kind of content from upstream.
|
|
```
|
|
HTTP/1.1 200 OK
|
|
Date: Sat, 16 Nov 2019 09:15:12 GMT
|
|
Transfer-Encoding: chunked
|
|
Connection: keep-alive
|
|
X-Server-id: 3
|
|
X-Server-status: on
|
|
|
|
{"code":"ok","message":"new json body"}
|
|
```
|
|
|
|
This means that the `response rewrite` plugin is in effect.
|
|
|
|
## Disable Plugin
|
|
When you want to disable the `response rewrite` plugin, it is very simple,
|
|
you can delete the corresponding json configuration in the plugin configuration,
|
|
no need to restart the service, it will take effect immediately:
|
|
```shell
|
|
curl http://127.0.0.1:9080/apisix/admin/routes/1 -X PUT -d '
|
|
{
|
|
"methods": ["GET"],
|
|
"uri": "/test/index.html",
|
|
"upstream": {
|
|
"type": "roundrobin",
|
|
"nodes": {
|
|
"127.0.0.1:80": 1
|
|
}
|
|
}
|
|
}'
|
|
```
|
|
|
|
The `response rewrite` plugin has been disabled now. It works for other plugins.
