`Script` represents a script that will be executed during the `HTTP` request/response life cycle.
|
||
|
|
|
||
|
|
The `Script` configuration can be directly bound to the `Route`.
|
||
|
|
|
||
|
|
`Script` and `Plugin` are mutually exclusive, and `Script` is executed first. This means that after configuring `Script`, the `Plugin` configured on `Route` will not be executed.
|
||
|
|
|
||
|
|
In theory, you can write arbitrary Lua code in `Script`, or you can directly call existing plugins to reuse existing code.
|
||
|
|
|
||
|
|
`Script` also has the concept of execution phase, supporting `access`, `header_filter`, `body_filter` and `log` phase. The system will automatically execute the code of the corresponding phase in the `Script` script in the corresponding phase.

|
```json
|
||
|
|
{
|
||
|
|
...
|
||
|
|
"script": "local _M = {} \n function _M.access(api_ctx) \n ngx.log(ngx.INFO,\"hit access phase\") \n end \nreturn _M"
|
||
|
|
}
|
||
|
|
```
