Go—GOPROXY代理 invalid $GOPROXY setting error

Go 由於是谷歌研發出品，很多開源依賴包都在國外服務器，down包經常會出現當不下來的情況，此時就需要設置$GOPROXY 代理，通過國內代理鏈接來獲取包資源。

常用代理路徑：https://goproxy.io/

網站打開很直白的介紹瞭如何設置$GOPROXY變量。

In Linux or macOS, you can execute the below commands.
Bash /
# Enable the go modules feature
export GO111MODULE=on
# Set the GOPROXY environment variable
export GOPROXY=https://goproxy.io
Or, write it into the .bashrc or .bash_profile file.
In Windows, you can execute the below commands.
PowerShell 
# Enable the go modules feature
$env:GO111MODULE=on
# Set the GOPROXY environment variable
$env:GOPROXY=https://goproxy.io
Now, when you build and run your applications, go will fetch dependencies via goproxy.io. See more information in the goproxy repository.
If your Go version >= 1.13, the GOPRIVATE environment variable controls which modules the go command considers to be private (not available publicly) and should therefore not use the proxy or checksum database. For example:
Go version >= 1.13
go env -w GOPROXY=https://goproxy.io,direct
# Set environment variable allow bypassing the proxy for selected modules
go env -w GOPRIVATE=*.corp.example.com

簡單操作一番

注：首先在通過go get 獲取包時，報invalid $GOPROXY setting error，通過分析報錯信息，並輸出$GOPROXY可見是我的代理鏈接沒對，根據ttps://goproxy.io/中guide執行export後，再go get package方可正常下載資源。最後直接在程序中import包即可使用。
