一、应用 go get获取
go getgo --helpGo is a tool for managing Go source code.
Usage:
go <command> [arguments]
The commands are:
bug start a bug report
build compile packages and dependencies
clean remove object files and cached files
doc show documentation for package or symbol
env print Go environment information
fix update packages to use new APIs
fmt gofmt (reformat) package sources
generate generate Go files by processing source
get add dependencies to current module and install them
install compile and install packages and dependencies
list list packages or modules
mod module maintenance
run compile and run Go program
test test packages
tool run specified go tool
version print Go version
vet report likely mistakes in packages
Use "go help <command>" for more information about a command.
Additional help topics:
buildconstraint build constraints
buildmode build modes
c calling between Go and C
cache build and test caching
environment environment variables
filetype file types
go.mod the go.mod file
gopath GOPATH environment variable
gopath-get legacy GOPATH go get
goproxy module proxy protocol
importpath import path syntax
modules modules, module versions, and more
module-get module-aware go get
module-auth module authentication using go.sum
module-private module configuration for non-public modules
packages package lists and patterns
testflag testing flags
testfunc testing functions
Use "go help <topic>" for more information about that topic.get add dependencies to current module and install them这就是咱们明天要用到的货色。
go get --helpusage: go get [-d] [-f] [-t] [-u] [-v] [-fix] [-insecure] [build flags] [packages]
Run 'go help get' for details.
找到咱们要获取的库。
https://github.com/go-sql-driver/mysqlgo get github.com/go-sql-driver/mysql后果报错：
go: missing Git command. See https://golang.org/s/gogetcmd
package github.com/go-sql-driver/mysql: exec: "git": executable file not found in %PATH%这里要装置Git，博主是装置了Git的，不过这里须要配置一下。
在零碎变量的PATH外面增加Git的bin目录的门路。
go get github.com/go-sql-driver/mysql当初就胜利了。
github.com/go-sql-driver/mysqlgo get| 仓库名 | VCS | VCS | VCS |
|---|---|---|---|
| BitBucket | Mercurial | Git | |
| GitHub | Git | ||
| Google Code Project Hosting | Git | Mercurial | Subversion |
| Launchpad | Bazaar |
go get二、间接下载GO库
在 github 或者其余中央下载Go库。
而后在零碎变量查看GOPATH。
而后关上GOPATH的src目录
将文件复制进去。
而后就胜利获取了。
三、参数介绍
usage: go get [-d] [-f] [-t] [-u] [-v] [-fix] [-insecure] [build flags] [packages]
Run 'go help get' for details.go help getThe -d flag instructs get to stop after downloading the packages; that is,
it instructs get not to install the packages.
The -f flag, valid only when -u is set, forces get -u not to verify that
each package has been checked out from the source control repository
implied by its import path. This can be useful if the source is a local fork
of the original.
The -fix flag instructs get to run the fix tool on the downloaded packages
before resolving dependencies or building the code.
The -insecure flag permits fetching from repositories and resolving
custom domains using insecure schemes such as HTTP. Use with caution.
The -t flag instructs get to also download the packages required to build
the tests for the specified packages.
The -u flag instructs get to use the network to update the named packages
and their dependencies. By default, get uses the network to check out
missing packages but does not use it to look for updates to existing packages.
The -v flag enables verbose progress and debug output.简略来说就是：
- -d 下载实现后就进行工作，不装置库
- -f 这个参数只有在应用了-u 参数时才有用，强制-u不去验证import的每一个包是否曾经获取了，这对本地fork的包十分有用。
- -fix 这个-fix参数示意在解决依赖关系或构建代码之前先运行fix工具。
- -insecure 该参数容许通过不平安（例如 HTTP）的自定义域获取并解析应用存储库。
- -t 该参数容许在下载该包时也下载测试该包须要的包。
- -u 参数容许 get 应用网络来更新包以及它们的依赖。默认状况下，get 应用网络查看失落的包，但不应用它来查找现有包的更新。
- -v 启用具体进度和调试信息输入。
