注册服务报“缺少 serviceName 参数

[USMQ]

系统 ubuntu 20 nacos-sdk-cpp 版本：1.0.8（C++ 版本）
nacos-server 版本：1.3.0（Java 版本）

修改 ：examples/registerInstances.cpp
#include
#include <unistd.h>

using namespace std;
using namespace nacos;

int main() {
Properties configProps;
configProps[PropertyKeyConst::SERVER_ADDR] = "10.1.27.20:8848";
NacosServiceFactory *factory = new NacosServiceFactory(configProps);
ResourceGuard _guardFactory(factory);
NamingService *namingSvc = factory->CreateNamingService();
ResourceGuard _serviceFactory(namingSvc);
Instance instance;
instance.clusterName = "DefaultCluster";
instance.ip = "192.168.64.253";
instance.port = 8888;

instance.ephemeral = true;

//Registers 5 services named TestNamingService-1...5
try {
    for (int i = 0; i < 5; i++) {
        NacosString serviceName = "TestNamingService-" + NacosStringOps::valueOf(i);
        instance.port = 1987 + i;
        std::cout << "IP:" << instance.ip << std::endl;
        std::cout << "Port: " << instance.port << std::endl;
        std::cout << "InstanceId: " << instance.instanceId << std::endl;
        std::cout << "Ephemeral: " << instance.ephemeral << std::endl;

        std::cout << "clusterName: " << instance.clusterName << std::endl;

        namingSvc->registerInstance(serviceName, instance);
    }
}
catch (NacosException &e) {
    cout << "encounter exception while registering service instance, raison:" << e.what() << endl;
    return -1;
}
sleep(300);
try {
    for (int i = 0; i < 5; i++) {
        NacosString serviceName = "TestNamingService" + NacosStringOps::valueOf(i);

        namingSvc->deregisterInstance(serviceName, "192.168.64.253", 1987 + i);
        sleep(1);
    }
}
catch (NacosException &e) {
    cout << "encounter exception while registering service instance, raison:" << e.what() << endl;
    return -1;
}
sleep(30);

return 0;

}

运行过程及运行结果如下：
g++ registerInstances.cpp -L. -lnacos-cli -I/usr/local/include/nacossdkcpp -o registerInstances.out
./registerInstances.out

IP:192.168.64.253
Port: 1987
InstanceId: 12345
Ephemeral: 1
ServiceName: TestNamingService-0
clusterName: DefaultCluster
Weight: 1
encounter exception while registering service instance, raison:failed to req API:/nacos/v1/ns/instance after all servers(http://10.1.27.20:8848) tried: failed to req API:http://10.1.27.20:8848/nacos/v1/ns/instance code:400 errormsg:caused: Param 'serviceName' is required.;

本机只运行了一个nacos server,是否还需要其他服务作为配置中心？

增加了configProps[PropertyKeyConst::LOG_LEVEL] = "DEBUG"; 输出的log
nacos-sdk-cpp.log
