[GitHub] [dubbo] yzlxlf opened a new issue, #10759: dubbo版本升级后，weight值修改问题
yzlxlf opened a new issue, #10759:
URL: https://github.com/apache/dubbo/issues/10759
consumer 版本alibaba dubbo 2.6.2
provider apache dubbo 2.7.15
loabbalance为：roundrobin
两个节点，两个节点权重都是默认的100
操作:修改zk中dubbo的providers中的某一个url中weight的值为0
现象:weight值被设置成0的节点仍有少量dubbo请求进入，估算为未设置时的1/50的流量
请问这个是啥原因

修改后注册中心都推送完毕了吗，可以consumer版本独立部署看下是哪个版本有问题

不好意思，问题已经得到解决
1、问题描述有误，实际我们修改的是configurators的url的override的节点的weight=0
2、出现2.7.15版本的流量无法摘除的原因是，版本2.7.15代码中解析url信息是解析encode 的url，如果写入节点中的是decode 的url，则2.7.15版本无法解析，而2.6.2版本，是先做decode，然后解析decode后的url，所以，2.7.15版本解析失败，导致weight=0解析失败，故流量无法摘除
