request help: application success but the plugins can't work

[Jimy-Guo]

Issue description

Environment

• your apisix-java-plugin-runner version
  apisix-plugin-runner:0.3.1-SNAPSHOT
  apache/apisix:2.15.1-centos

使用的dockerfile为

FROM apache/apisix:2.15.1-centos
#指定镜像创建者信息
MAINTAINER jimyguo
#将宿主机的文件拷贝到容器的具体目录中。这里使用ADD，拷贝后自动解压，如果不需要解压，可以使用COPY
ADD jdk-11.0.16.1_linux-x64_bin.tar.gz /jdk
ADD apache-apisix-java-plugin-runner-0.3.1-SNAPSHOT-bin.tar.gz /opt
ADD apisix-java-plugin-runner-0.3.1-SNAPSHOT-src.tgz /usr/local
#配置jdk环境
ENV JAVA_HOME /jdk/jdk-11.0.16.1
ENV PATH ${JAVA_HOME}/bin:$PATH

Minimal test code / Steps to reproduce the issue

1.在正常打包出来的jar包按照https://github.com/apache/apisix-java-plugin-runner/blob/main/docs/en/latest/how-it-works.md
启动之后以下代码中检出System.getProperty("user.dir")为/usr/local/apisix导致HotReloadProcess.hotReloadFilter()报错

String userDir = System.getProperty("user.dir");
        System.err.println(userDir);
//使用了这个代码之后加入apisix-java-plugin-runner-0.3.1-SNAPSHOT-src.tgz到/usr/local就无报错
//        userDir=userDir.replace("apisix","apisix-java-plugin-runner");
        logger.warn("The filter userDir  {} ", userDir);
        userDir = userDir.substring(0, userDir.lastIndexOf("apisix-java-plugin-runner") + 25);
        String workDir = userDir + loadPath;

2、修改启动成功后，使用的插件对应的配置为

 "ext-plugin-pre-req": {
      "conf": [
        {
          "name": "TokenCheckFilter2",
          "value": "{\"validate_header\":\"token\",\"rejected_code\":\"403\"}"
        }
      ]
    },

启动时以下程序的代码没有打印出对应plugin 的日志，如 logger.debug("get plugins List:{}",pluginFilterList),是否就是没有检测到插件并加以使用

public void start(String path) throws Exception {
        EventLoopGroup group = null;
        ServerBootstrap bootstrap = new ServerBootstrap();
        logger.debug("choose channel");
        System.err.println("choose channel");
        if (KQueue.isAvailable()) {
            group = new KQueueEventLoopGroup();
            logger.debug("Using epoll for Netty transport.");
            bootstrap.group(group).channel(KQueueServerDomainSocketChannel.class);
        } else if (Epoll.isAvailable()) {
            group = new EpollEventLoopGroup();
            logger.debug("Using kqueue for Netty transport.");
            bootstrap.group(group).channel(EpollServerDomainSocketChannel.class);
        } else {
            String errMsg = "java runner is only support epoll or kqueue";
            logger.debug(errMsg);
            throw new RuntimeException(errMsg);
        }
        logger.debug("choose channel success");
        System.err.println("choose channel success");
        try {
            initServerBootstrap(bootstrap);
            ChannelFuture future = bootstrap.bind(new DomainSocketAddress(path)).sync();
            Runtime.getRuntime().exec("chmod 777 " + socketFile);
            logger.warn("java runner is listening on the socket file: {}", socketFile);

            future.channel().closeFuture().sync();
        } finally {
            group.shutdownGracefully().sync();
        }
    }
private void initServerBootstrap(ServerBootstrap bootstrap) {
        logger.debug("start init bootstrap");
        System.err.println("start init bootstrap");
        bootstrap.childHandler(new ChannelInitializer<DomainSocketChannel>() {
            @Override
            protected void initChannel(DomainSocketChannel channel) {
                channel.pipeline().addFirst("logger", new LoggingHandler())
                        .addAfter("logger", "payloadEncoder", new PayloadEncoder())
                        .addAfter("payloadEncoder", "delayedDecoder", new BinaryProtocolDecoder())
                        .addLast("payloadDecoder", new PayloadDecoder())
                        .addAfter("payloadDecoder", "prepareConfHandler", createConfigReqHandler(cache, beanProvider))
                        .addAfter("prepareConfHandler", "hTTPReqCallHandler", createA6HttpHandler(cache))
                        .addLast("exceptionCaughtHandler", new ExceptionCaughtHandler());

            }
        });
        System.err.println("start bootstrap success");
    }
    public PrepareConfHandler createConfigReqHandler(Cache<Long, A6Conf> cache, ObjectProvider<PluginFilter> beanProvider) {
        List<PluginFilter> pluginFilterList = beanProvider.orderedStream().collect(Collectors.toList());
        Map<String, PluginFilter> filterMap = new HashMap<>();
        logger.debug("get plugins List:{}",pluginFilterList);
        System.err.println("get plugins List:"+pluginFilterList);
        for (PluginFilter filter : pluginFilterList) {
            System.err.println(filter.name());
            filterMap.put(filter.name(), filter);
        }
        return new PrepareConfHandler(cache, filterMap);
    }

调用了接口之后时应该会使用到TokenCheckFilter2

@Override
    public String name() {
        return "TokenCheckFilter2";
    }
   @Override
    public void filter(HttpRequest request, HttpResponse response, PluginFilterChain chain) {
        log.info("TokenCheckFilter start");
        // parse `conf` to json
        String configStr = request.getConfig(this);
        Gson gson = new Gson();
        Map<String, Object> conf = new HashMap<>();
        conf = gson.fromJson(configStr, conf.getClass());

        // get configuration parameters
        String token = request.getHeader((String) conf.get("validate_header"));// token verification results

        Map<String, String> headers = request.getHeaders(); 

        Map<String, String> body = new HashMap<>();
        body = gson.fromJson(request.getBody(),body.getClass());// token verification results


        Map<String, String> params = request.getArgs();
        String rejectedCode ="0";
        if(checkAppIdToken(body)){
            log.info("token success");
            response.setBody(JsonResult.success().toString());
        }else {
            if(checkAppIdToken(params)) {
                log.info("token success");
                response.setBody(JsonResult.success().toString());
            }else {
                log.info("token failed");
                rejectedCode = (String) conf.get("rejected_code");
                response.setStatusCode(Integer.parseInt(rejectedCode));
                response.setHeader("x-token","no token");
                response.setBody(JsonResult.fail(GlobalResultStatus.AUTH_MISSING).toString());
            }
        }
        chain.filter(request, response);
    }
    public boolean checkAppIdToken(Map<String, String> map) {
        return map.containsKey("appId")&& map.containsKey("accessToken");
    }
   @Override
    public void postFilter(PostRequest request, PostResponse response, PluginFilterChain chain) {

    }
    @Override
    public List<String> requiredVars() {
        List<String> vars = new ArrayList<>();
        vars.add("appId");
        vars.add("accessToken");
        return vars;
    }

    @Override
    public Boolean requiredBody() {
        return true;
    }

对应的日志为

能够直接访问且没有出现对应插件中的日志打印，故判断插件确实没有生效

What's the actual result? (including assertion message & call stack if applicable)

请求没有通过插件的检测返回配置的数据，能够访问成功

What's the expected result?

当请求没有待遇偶需要的appId和accessToken会返回接口配置的rejected_code:403.

1. please adjust the format of the different contents of the issue (code, issue description, etc.), it's too confusing now.

it seems that all are successful,but the plugins are not working

1. what is the route you added on APISIX (route to configure java plugin runner)
2. how do you verify that the plugin is not working? I need this reproduction process like: bug: 使用apisix的ext-plugin-post-resp插件配合apisix-java-plugin-runner0.3.0支持过滤上游响应标头时，上游返回状态码为204时，会重复发送http的请求的问题 #189 (comment)

我已经修改了，请您再看一看

[tzssangglass]

Possible errors I see.

1. the built jar does not contain your custom filter;
2. 0.3.1-SNAPSHOT contains errors.

I suggest you

1. use 0.4.0 (already released)
2. try with https://github.com/apache/apisix-java-plugin-runner/blob/main/docs/en/latest/installation-guide.md#install， example: https://github.com/tzssangglass/java-plugin-runner-demo-1

原来的apache-apisix-java-plugin-runner已经更新代码生成使用apache-apisix-java-plugin-runner-0.4.0-bin.tar.gz，插件仍然没有起效：

"plugins": {
    "ext-plugin-pre-req": {
      "conf": [
        {
          "name": "StopRequestDemoFilter",
          "value": "{\"stop_response_body\":\"{\"hello\":\"success\"}\",\"stop_response_header_name\":\"x-test-header\",\"stop_response_header_value\":\"success\",\"stop_response_code\":\"401\"}"
        }
      ]
    },

对应的StopRequestDemoFilter为

@Component
public class StopRequestDemoFilter implements PluginFilter {
    @Override
    public String name() {
        return "StopRequestDemoFilter";
    }

    @Override
    public void filter(HttpRequest request, HttpResponse response, PluginFilterChain chain) {
        /*
         * If the conf you configured is of type json, you can convert it to Map or json.
         */

        String configStr = request.getConfig(this);
        Gson gson = new Gson();
        Map<String, Object> conf = new HashMap<>();
        conf = gson.fromJson(configStr, conf.getClass());

        /*
         * You can use the parameters in the configuration.
         */
        response.setStatusCode(Double.valueOf(conf.get("stop_response_code").toString()).intValue()); 
        response.setHeader((String) conf.get("stop_response_header_name"), (String) conf.get("stop_response_header_value"));
        /* note: The body is currently a string type.
                 If you need the json type, you need to escape the json content here.
                 For example, if the body is set as below
                 "{\"key1\":\"value1\",\"key2\":2}"

                 The body received by the client will be as below
                 {"key1":"value1","key2":2}
         */
        response.setBody((String) conf.get("stop_response_body"));

        /*  Using the above code, the client side receives the following

            header:
            HTTP/1.1 401 Unauthorized
            Content-Type: text/plain; charset=utf-8
            Connection: keep-alive
            new-header: header_by_runner
            Server: APISIX/2.6

            body:
            {"key1":"value1","key2":2}
         */
        chain.filter(request, response);
    }

    @Override
    public List<String> requiredVars() {
        return null;
    }

    @Override
    public Boolean requiredBody() {
        return null;
    }
}

按照逻辑来讲是无论成功与否都是返回401的，但是仍然返回：

明显没有生效，这是还有什么其他我需要添加的内容吗？
文档中https://github.com/apache/apisix-java-plugin-runner/blob/main/docs/en/latest/installation-guide.md#install%EF%BC%8C的
Add the apisix-java-plugin-runner dependency in your POM, like:

org.apache.apisix
apisix-runner-starter
0.4.0

这一部分是加在哪里的呢？

[Jimy-Guo]

Possible errors I see.

1. the built jar does not contain your custom filter;
2. 0.3.1-SNAPSHOT contains errors.

I suggest you

1. use 0.4.0 (already released)
2. try with https://github.com/apache/apisix-java-plugin-runner/blob/main/docs/en/latest/installation-guide.md#install， example: https://github.com/tzssangglass/java-plugin-runner-demo-1

我将https://github.com/tzssangglass/java-plugin-runner-demo-1的程序打包后，修改了以下地方的配置
java-plugin-runner-demo的application.yaml：

logging:
  level:
    root: debug
cache.config:
  expired: ${APISIX_CONF_EXPIRE_TIME}
  capacity: 1000

socket:
  file: ${APISIX_LISTEN_ADDRESS}

使用的DockerFile为：

#进入文件后
#依赖镜像名称和ID
FROM apache/apisix:2.15.1-debian
#指定镜像创建者信息
MAINTAINER jimyguo
#将宿主机的文件拷贝到容器的具体目录中。这里使用ADD，拷贝后自动解压，如果不需要解压，可以使用COPY
ADD jdk-11.0.16.1_linux-x64_bin.tar.gz /jdk
#ADD apache-apisix-java-plugin-runner-0.3.1-SNAPSHOT-bin.tar.gz /usr/local

#RUN apt -y install openjdk-11-jdk

#ADD apache-apisix-java-plugin-runner-0.4.0-bin.tar.gz /usr/local
ADD demo-0.0.1-SNAPSHOT.jar /usr/local
#ADD apisix-java-plugin-runner-0.4.0-SNAPSHOT-src.tgz /usr/local

#
### 配置jdk环境
ENV JAVA_HOME /jdk/jdk-11.0.16.1
ENV PATH ${JAVA_HOME}/bin:$PATH

apisix的config.yaml:

ext-plugin:
  cmd: ['java', '-jar', '-Xmx4g', '-Xms4g', '/usr/local/demo-0.0.1-SNAPSHOT.jar']

路由上配置为：

"plugins": {
    "ext-plugin-pre-req": {
      "conf": [
        {
          "name": "DemoFilter",
          "value": "{\"enable\":\"feature\"}"
        }
      ]
    },

配置完之后日志可见

可见未打印logger.warn("DemoFilter is running");，需确定是还有什么地方漏了吗？

my full route config is:

curl -i http://127.0.0.1:9080/apisix/admin/routes/1  -H 'X-API-KEY: edd1c9f034335f136f87ad84b625c8f1' -X PUT -d '
{
    "uri": "/get",
    "plugins": {
        "ext-plugin-pre-req": {
            "conf" : [
                {"name": "DemoFilter", "value": "{\"enable\":\"feature\"}"}
            ]
        }
    },
    "upstream": {
        "type": "roundrobin",
        "nodes": {
            "httpbin.org:80": 1
        }
    }
}'

and test it like:

curl http://127.0.0.1:9080/get

send request to hit route which has ext-plugin-pre-req plugin.

创建相同route的时候报错，为以下报错：

@Jimy-Guo I have the same problem as you，please modify apisix-docker/example/apisix_conf/config.yml，enbaled plugin，like this：
plugins:

• skywalking # 启用skywalking插件
• ext-plugin-pre-req # 开启插件
