### help request: How to modify request body in apisix pre-plugin
(ext-plugin-pre-req)? Ask the technical teacher to help me, thank you!
The ext-plugin-pre-req plug-in is enabled in the apisix routing
configuration, how to modify the request body in the plug-in filter method?
The routing configuration information is as follows:
```json
{
"uri": "/test-api/*",
"name": "测试api",
"desc": "测试api",
"methods": [
"GET",
"POST"
],
"plugins": {
"ext-plugin-pre-req": {
"allow_degradation": false,
"conf": [
{
"name": "AuthFilter",
"value": "authFilter"
}
],
"disable": false
}
},
"service_id": "1669247957284687873",
"labels": {
"API_VERSION": "v1"
},
"status": 1
}
```
The plug-in execution code is as follows:
```java
@component
public class AuthFilter implements PluginFilter {
private final Logger logger = LoggerFactory. getLogger(AuthFilter. class);
@Override
public String name() {
return "AuthFilter";
}
@Override
public void filter(HttpRequest request, HttpResponse response,
PluginFilterChain chain) {
logger.info("【Enter pre-intercept filter】");
logger.info("【Acquired request parameters】" + request.getBody());
// How to modify the request parameters here, and reset the request
parameters to the upstream service
chain. filter(request, response);
}
@Override
public void postFilter(PostRequest request, PostResponse response,
PluginFilterChain chain) {
logger.info("【Enter post-interception filter】");
chain. postFilter(request, response);
}
@Override
public List<String> requiredVars() {
List<String> vars = new ArrayList<>();
vars.add("request_id");
return vars;
}
@Override
public Boolean requiredBody() {
return true;
}
@Override
public Boolean requiredRespBody() {
return true;
}
```
Please help me, technical teachers, thank you!
