问题

今天调用上传接口上传文件时，遇到了一个 x509 类型报错，具体报错信息如下：

2021-10-15 17:46:13.145 ERROR oss/upload.go:210 upload process Failed {“error”: “Post “https://192.168.215.139:9443/store/file/upload”: x509: cannot validate certificate for 192.168.215.139 because it doesn’t contain any IP SANs”}
panic: send on closed channel

解决

网上也找了很多其他方法，看似很正确，实际上没有解决自己遇到的问题，于是自己找到了一种解决方法。

首先分析问题的大致原因是认证机制出了问题。

自己回想起之前也遇到一个 x509 的报错，但是具体的错误提示不一样，于是自己怀疑他们是不是属于一类错误呢？反正也没有什么好方法，那就死马当成活马医吧！

具体命令如下，步骤一：

sudo apt-get update

输出结果：

重启上传服务，再次调用上传接口，报错消失，问题解决了，赞！
