rongxianjie opened a new issue, #232:
URL: https://github.com/apache/apisix-java-plugin-runner/issues/232
### Issue description
I want to get the upstream response content in the plugin for processing and then return to the client, but it return null
This is how the class is handled：
@Override
public void postFilter(PostRequest request, PostResponse response, PluginFilterChain chain) {
log.warn("ClientAuthenticationFilter is running");
log.warn("status:{}", request.getUpstreamStatusCode());
// get the upstream response body
String responseBody = request.getBody();
ResultData<ActivityLoginUser> resultData = JsonUtils.json2Bean(responseBody , ResultData.class);
ResultData<AuthUserVo> authResult = new ResultData<>();
authResult.setCode(resultData.getCode());
authResult.setMessage(resultData.getMessage());
if(ObjectUtils.isNotEmpty(resultData.getData())){
AuthUserVo authUserVo = processAuthResult(resultData.getData());
authResult.setData(authUserVo);
}
response.setBody(JsonUtils.bean2Json(authResult));
chain.postFilter(request, response);
}
java.lang.NullPointerException: null
at com.taikang.tlife.activity.apisix.plugins.fliters.ClientAuthenticationFilter.postFilter(ClientAuthenticationFilter.java:85)

The line String responseBody = request.getBody();
the responseBody is null, when process it in processAuthResult, it throws NullPointerException.
I want to know how to get the upstream reponse content. because the " request.getBody()" cant get the upstream body.
