网上说出现的问题是由于两种原因

1、nocos未启动

我本地的nacos已经启动

2、未导入依赖

        <dependency>
            <groupId>com.alibaba.cloud</groupId>
            <artifactId>spring-cloud-starter-alibaba-nacos-discovery</artifactId>
        </dependency>

找了很久发现上边的两种情况都不是原因，而是我的配置文件中多了一个空格

com.alibaba.nacos.api.exception.NacosException: failed to req API:/nacos/v1/ns/instance,springcloud,spring cloud
