Set up the Go Modules and proxy

Go Modules is the Go language dependency management solution

Mod file field content

Go.mod is the most important file required for a Go Moduels-enabled project. It describes the meta information for the current project (that is, the current module), and each line begins with a verb, which currently has the following five verbs:

  • Module: Defines the module path for the current project.
  • Go: Used to set the expected GO version.
  • Require: Used to set a specific module version.
  • Exclude: Used to exclude a particular module version from use.
  • Replace: Used to replace one module version with another.

Open the go. The mod

  1. Open Go Modules:go env -w GO111MODULE=on.
  2. Set GOPROXY:go env -w GOPROXY=https://goproxy.cn,direct# is required in China because its default value is blocked.
  3. Execute in the root directory of your projectgo mod init <OPTIONAL_MODULE_PATH>To generate the go.mod file.

Go modules Common command

  1. Use Go Help module-get and Go Help Gopath -get to understand the go Get behavior in the go Modules enabled and not enabled states respectively

  2. Pull new dependencies with Go Get

    • Pull the latest version (tag is preferred) :go get golang.org/x/text@latest
    • pullmasterBranch’s latest COMMIT:go get golang.org/x/text@master
    • Pull commit with tag v0.3.2:Go get golang.org/x/[email protected]
    • Pull commit with hash 342b231, which will be converted to v0.3.2:go get golang.org/x/text@342b2e
    • withgo get -uUpdate existing dependencies
    • withgo mod downloadDownload all dependencies specified in the go.mod file
    • withgo mod tidySort out existing dependencies
    • withgo mod graphLook at existing dependency structures
    • withgo mod initGenerate go.mod files (the only subcommand in Go 1.13 that can generate go.mod files)

  3. Edit the go.mod file with Go Mod Edit

  4. Export all existing dependencies with Go Mod Vendor (actually Go Modules are de-emphasizing the concept of vendor)

  5. Use Go Mod Verify to verify if a module has been tampered with
