注意看nacos地址后面少一个8

spring.cloud.nacos.config.server-addr=127.0.0.1:8848
spring.cloud.nacos.config.namespace=c05c7a06-5325-4444-ac2f-dddbc91196c0

spring.cloud.nacos.config.ext-config[0].data-id=oss.yml
spring.cloud.nacos.config.ext-config[0].group=DEFAULT_GROUP
spring.cloud.nacos.config.ext-config[0].refresh=true

这是配置的地址

解决办法
去掉nacos地址的http

spring.cloud.nacos.config.server-addr=127.0.0.1:8848
spring.cloud.nacos.config.namespace=c05c7a06-5325-4444-ac2f-dddbc91196c0

spring.cloud.nacos.config.ext-config[0].data-id=oss.yml
spring.cloud.nacos.config.ext-config[0].group=DEFAULT_GROUP
spring.cloud.nacos.config.ext-config[0].refresh=true

OK
