GO GOPROXY proxy Settings

A background:

Show timeout when you execute go get command proxy.golang.org --> timeout

leyangjundeMacBook-Pro:photoleyangjun$ go get -u github.com/spf13/cobra
go get -u github.com/spf13/cobra

go get github.com/spf13/cobra: module github.com/spf13/cobra: Get https://proxy.golang.org/github.com/spf13/cobra/@v/list: dial tcp 142.251.10.141:443: i/o timeout

Two: Reasons

https://proxy.golang.org/github.com/ cannot be accessed in China

Third: Change to a domestic accessible address and set up a GOPROXY proxy

go env -w GOPROXY=https://goproxy.cn,direct

go env -w GOSUMDB=off (turn off package validation)

go env -w GOSUMDB=“sum.golang.google.cn” (sum verification service provided in China can also be set)

Note: the -w flag requires one or more parameters of the form NAME=VALUE and overrides the default setting

Let me introduce myself first. The editor graduated from Jiaotong University in 2013. I worked in a small company and went to big factories such as Huawei and OPPO. I joined Ali in 2018, until now.I know that most junior and intermediate java engineers want to upgrade their skills, they often need to explore their own growth or sign up to study, but for training institutions, the tuition fee is nearly 10,000 yuan, which is really stressful.Self-learning that is not systematic is very inefficient and lengthy, and it is easy to hit the ceiling and the technology stops.Therefore, I collected a "full set of learning materials for java development" for everyone. The original intention is also very simple. I hope to help friends who want to learn by themselves but don't know where to start, and at the same time reduce everyone's burden.Add the business card below to get a full set of learning materials
