request help: Java 自定义插件，实现postFilter，但是无法获取上游服务响应的数据 apisix-version ：2.15

[Forever-ZF]

apisix-version ：2.15 现在有个上游服务响应数据 是一串字符串。如 ：post请求

插件代码如下：

public void postFilter(PostRequest request, PostResponse response, PluginFilterChain chain) { System.out.println("执行了 ext-plugin-post-resp 插件"); String configStr = request.getConfig(this); String json = null; Gson gson = new Gson(); Map<String, Object> conf = new HashMap<>(); conf = gson.fromJson(configStr, conf.getClass()); String param = (String) conf.get("param"); System.out.println("param参数---------" + param + "--------------"); String body = request.getBody(); ObjectMapper objectMapper = new ObjectMapper(); try { System.out.println("request--------" +objectMapper.writeValueAsString(request)); System.out.println("request.getBody()--------" +request.getBody()); System.out.println("request.getUpstreamHeaders()--------" +objectMapper.writeValueAsString(request.getUpstreamHeaders())); System.out.println("response--------" +objectMapper.writeValueAsString(response)); } catch (Exception e) { throw new RuntimeException(e); } chain.postFilter(request, response); }

日志如下

2023/10/30 06:16:39 [warn] 48#48: 88 [lua] init.lua:913: 执行了 ext-plugin-post-resp 插件 param参数---------username;telephone-------------- , context: ngx.timer 2023/10/30 06:16:39 [warn] 48#48: 88 [lua] init.lua:913: request--------{"requestId":8388608,"body":null,"upstreamHeaders":{"Keep-Alive":"timeout=60","Connection":"keep-alive","Content-Length":"10","Date":"Mon, 30 Oct 2023 06:17:38 GMT","Content-Type":"text/plain;charset=UTF-8"},"confToken":1047925334,"upstreamStatusCode":200,"type":4} request.getBody()--------null request.getUpstreamHeaders()--------{"Keep-Alive":"timeout=60","Connection":"keep-alive","Content-Length":"10","Date":"Mon, 30 Oct 2023 06:17:38 GMT","Content-Type":"text/plain;charset=UTF-8"} response--------{"errResponse":null,"type":4}

request中的"Content-Length":"10" 对应 post请求 是准确的，但是无法获取对应信息，该怎么解决？
