node_log.h

`node_log.h` 是一个头文件，通常用于在 C/C++ 代码中实现日志记录功能。在 Node.js 中，它是用于记录 Node.js 应用程序日志的头文件。

`node_log.h` 定义了几个日志级别，包括 `NODE_LOG_DEBUG`、`NODE_LOG_INFO`、`NODE_LOG_WARN` 和 `NODE_LOG_ERROR`。开发者可以使用这些级别来输出不同程度的日志信息。

例如，以下是使用 `node_log.h` 记录的示例代码：

#include "node_log.h"

int main() {
  NODE_LOG_INFO("Hello, world!");
  NODE_LOG_DEBUG("This is a debug message.");
  NODE_LOG_WARN("Warning: something is not right.");
  NODE_LOG_ERROR("Error: something went wrong!");
  return 0;
}

在上面的示例中，`NODE_LOG_INFO`、`NODE_LOG_DEBUG`、`NODE_LOG_WARN` 和 `NODE_LOG_ERROR` 分别输出不同级别的日志信息。开发者可以根据实际情况选择合适的日志级别，帮助调试和定位问题。

帮我修改下面的代码。要求建立一次weboscket链接，链接到wss://autopilot-test.t3go.cn:443/api/v1/vehicle/push/message/LFB1FV696M2L43840，当订阅到感知话题调用perceptionCallback时，通过wss发送serialized_data：#include "ros/ros.h" #include "std_msgs/String.h" #include <boost/thread/locks.hpp> #include <boost/thread/shared_mutex.hpp> #include "third_party/apollo/proto/perception/perception_obstacle.pb.h" #include "t3_perception.pb.h" #include <iostream> #include <websocketpp/config/asio_client.hpp> #include <websocketpp/client.hpp> #include <websocketpp/common/thread.hpp> apollo::perception::PerceptionObstacles perception_obstacles_; typedef websocketpp::clientwebsocketpp::config::asio_tls_client client; void perceptionCallback(const std_msgs::String& msg) { ROS_WARN("t3 perceptionCallback parse"); if (perception_obstacles_.ParseFromString(msg.data)) { double timestamp = perception_obstacles_.header().timestamp_sec(); ROS_INFO("t3 perceptionCallback timestamp %f count:%d", timestamp, perception_obstacles_.perception_obstacle().size()); std::string data; perception_obstacles_.SerializeToString(&data); VehData veh_data; veh_data.set_messagetype(5); veh_data.set_messagedes("PerceptionObstacles"); veh_data.set_contents(data); std::string serialized_data; veh_data.SerializeToString(&serialized_data); } else { ROS_ERROR("t3 perceptionCallback parse fail!"); } } int main(int argc, char **argv) { ros::init(argc, argv, "listener"); ros::NodeHandle n; ros::Subscriber sub = n.subscribe("/perception_node/perception_objects", 1000, perceptionCallback); ros::spin(); return 0; }

好的，这里是修改后的代码：

#include "ros/ros.h"
#include "std_msgs/String.h"
#include <boost/thread/locks.hpp>
#include <boost/thread/shared_mutex.hpp>
#include "third_party/apollo/proto/perception/perception_obstacle.pb.h"
#include "t3_perception.pb.h"
#include <iostream>
#include <websocketpp/config/asio_client.hpp>
#include <websocketpp/client.hpp>
#include <websocketpp/common/thread.hpp>

using namespace std;

apollo::perception::PerceptionObstacles perception_obstacles_;
typedef websocketpp::client<websocketpp::config::asio_tls_client> client;

void perceptionCallback(const std_msgs::String& msg, client* c) {
    ROS_WARN("t3 perceptionCallback parse");

    if (perception_obstacles_.ParseFromString(msg.data)) {
        double timestamp = perception_obstacles_.header().timestamp_sec();
        ROS_INFO("t3 perceptionCallback timestamp %f count:%d", timestamp, perception_obstacles_.perception_obstacle().size());

        std::string data;
        perception_obstacles_.SerializeToString(&data);

        VehData veh_data;
        veh_data.set_messagetype(5);
        veh_data.set_messagedes("PerceptionObstacles");
        veh_data.set_contents(data);

        std::string serialized_data;
        veh_data.SerializeToString(&serialized_data);

        try {
            c->send(serialized_data);
        } catch (const websocketpp::exception& e) {
            ROS_ERROR("t3 perceptionCallback send failed: %s", e.what());
        }
    } else {
        ROS_ERROR("t3 perceptionCallback parse fail!");
    }
}

int main(int argc, char **argv) {
    ros::init(argc, argv, "listener");
    ros::NodeHandle n;
    ros::Subscriber sub = n.subscribe("/perception_node/perception_objects", 1000,
                                      boost::bind(&perceptionCallback, _1, new client()));

    client* c = sub.getCallbackQueue()->getCallbackThread().get_context<client>();
    c->set_access_channels(websocketpp::log::alevel::none);
    c->set_error_channels(websocketpp::log::elevel::none);

    websocketpp::lib::error_code ec;
    client::connection_ptr con = c->get_connection("wss://autopilot-test.t3go.cn:443/api/v1/vehicle/push/message/LFB1FV696M2L43840", ec);

    if (ec) {
        ROS_ERROR("t3 websocket connection failed: %s", ec.message().c_str());
        return 1;
    }

    c->connect(con);
    ROS_INFO("t3 websocket connected");

    ros::spin();
    return 0;
}

主要的修改包括：

1. 将 `websocketpp::clientwebsocketpp::config::asio_tls_client` 改为 `websocketpp::client<websocketpp::config::asio_tls_client>`，因为 `websocketpp` 3.0 版本后改变了类模板的定义。
2. 修改 `perceptionCallback` 函数，将 `serialized_data` 发送到 websocket 服务器。由于该函数是回调函数，需要将 client 指针作为参数传递进去，这里使用 `boost::bind` 来实现。
3. 在 `main` 函数中建立 websocket 连接，并将 client 指针传递给 `perceptionCallback` 函数。注意要将 client 的日志级别设置为 none，以避免输出过多的日志。

It seems like there is a compilation error in your code. The error message indicates that the file "glog/logging.h" is not found. This file is part of the Google Logging Library (glog) and needs to be installed in order to compile your code successfully.

To resolve this issue, you can follow these steps:

1. Make sure that the glog library is installed on your system. You can check this by running the following command in your terminal:

   dpkg -l libgoogle-glog-dev

If it is not installed, you can install it using the package manager specific to your system (e.g., apt for Ubuntu):

   sudo apt-get install libgoogle-glog-dev

2. After installing the glog library, try compiling your code again. If the error persists, make sure that the glog library directory is included in the compilation flags. You can add the following line to your CMakeLists.txt file:

   include_directories(/path/to/glog/include)

Replace "/path/to/glog/include" with the actual path to the glog library include directory on your system.

3. Save the changes to your CMakeLists.txt file and try compiling your code again.

If you continue to encounter issues, please provide more details about your development environment and the steps you have already taken to troubleshoot the problem.
