GO语言学习笔记（二） - GUI For Go（基于Electron）

前言

网上找了一下Golang的GUI，然后找到了一个基于Electron的介绍。
一开始觉得应该比较简单，但是还是碰到各种坑。
所以将碰到的一些坑和解决方法在这里记录一下。

使用Eletron作为Golang GUI的文章链接：
https://studygolang.com/articles/12065?fr=sidebar

简介

基于Electron，使用go-astilectron作为Golang和Electron的连接媒介。

go-astilectron Github地址：
https://github.com/asticode/go-astilectron

go-astilectron示例 Github地址：
https://github.com/asticode/go-astilectron-demo

配置

在GOPATH下新建 src, pkg, bin三个文件夹

执行Demo提供的命令

Github上Demo的readme中的命令

安装示例

下面的命令都是在PowerShell6.1.0-preview.1中执行的
操作过程中忘了关掉VPN了，在不的情况下不能保证一定能成功。

下载代码

go get -u github.com/asticode/go-astilectron-demo/...

然后就出错误了。
错误信息如下：

PS C:\Program Files\PowerShell\6.1.0-preview.1> go get -u github.com/asticode/go
-astilectron-demo/...
package github.com/asticode/go-astilectron-demo
        imports golang.org/x/crypto/ssh/terminal: unrecognized import path "gola
ng.org/x/crypto/ssh/terminal" (https fetch: Get https://golang.org/x/crypto/ssh/
terminal?go-get=1: dial tcp 216.239.37.1:443: connectex: A connection attempt fa
iled because the connected party did not properly respond after a period of time
, or established connection failed because connected host has failed to respond.
)
PS C:\Program Files\PowerShell\6.1.0-preview.1>

解决方法：

1 在GOPATH目录下的src目录新建目录golang.org，在golang.org目录下新建目录x，并进入到新建的目录x中。

PS C:\Program Files\PowerShell\6.1.0-preview.1> cd $GOPATH
PS C:\Users\Administrator> cd go
PS C:\Users\Administrator\go> cd src
PS C:\Users\Administrator\go\src> mkdir golang.org
略（此行非命令）
PS C:\Users\Administrator\go\src> cd golang.org
PS C:\Users\Administrator\go\src\golang.org> mkdir x
略（此行非命令）
PS C:\Users\Administrator\go\src\golang.org> cd x
PS C:\Users\Administrator\go\src\golang.org\x>

2.执行命令下载crypto。
注：前提是已安装Git。

git clone https://github.com/golang/crypto.git

执行过程

PS C:\Users\Administrator\go\src\golang.org\x> git clone https://github.com/gola
ng/crypto.git
Cloning into 'crypto'...
remote: Counting objects: 4615, done.
remote: Compressing objects: 100% (32/32), done.

Resolving deltas: 100% (2933/2933), done.
PS C:\Users\Administrator\go\src\golang.org\x>

继续执行下载代码的命令

go get -u github.com/asticode/go-astilectron-demo/...

然后继续出错。

PS C:\Program Files\PowerShell\6.1.0-preview.1> go get -u github.com/asticode/go
-astilectron-demo/...
package golang.org/x/sys/windows: unrecognized import path "golang.org/x/sys/win
dows" (https fetch: Get https://golang.org/x/sys/windows?go-get=1: dial tcp 216.

 did not properly respond after a period of time, or established connection fail
ed because connected host has failed to respond.)
PS C:\Program Files\PowerShell\6.1.0-preview.1>

解决方法：

进入到上面说的golang.org/x目录下，执行命令下载sys。
注：前提是已安装Git。

git clone https://github.com/golang/sys.git

执行过程

PS C:\Users\Administrator\go\src\golang.org\x> git clone https://github.com/gola
ng/sys.git
Cloning into 'sys'...
remote: Counting objects: 5475, done.

Resolving deltas: 100% (4609/4609), done.
PS C:\Users\Administrator\go\src\golang.org\x>

继续执行下载命令
出现下面的信息即为下载成功，其中的undefined: xxx 可忽略。

PS C:\Program Files\PowerShell\6.1.0-preview.1> go get -u github.com/asticode/go
-astilectron-demo/...
# github.com/asticode/go-astilectron-demo
C:\Users\Administrator\go\src\github.com\asticode\go-astilectron-demo\main.go:35
:13: undefined: Asset
C:\Users\Administrator\go\src\github.com\asticode\go-astilectron-demo\main.go:36
:13: undefined: AssetDir
C:\Users\Administrator\go\src\github.com\asticode\go-astilectron-demo\main.go:76
:18: undefined: RestoreAssets
PS C:\Program Files\PowerShell\6.1.0-preview.1>

删除bind.go
进入到go-astilectron-demo所在目录，删除bind.go文件。

好像不删除会出问题。
不一定非得使用命令删除。

PS C:\Users\Administrator\go\src\github.com\asticode\go-astilectron-demo> rm bin
d.go
PS C:\Users\Administrator\go\src\github.com\asticode\go-astilectron-demo>

安装bundler

！需要把$GOPATH/bin添加到系统环境变量$PATH中，不然会提示找不到命令！

Windows的系统环境变量PATH

%GOPATH%\bin;

执行命令安装bundler

go get -u github.com/asticode/go-astilectron-bundler/...

执行过程

PS C:\Program Files\PowerShell\6.1.0-preview.1> go get -u github.com/asticode/go
-astilectron-bundler/...
PS C:\Program Files\PowerShell\6.1.0-preview.1>

在当前环境中bundle应用程序

bundle应用程序
进入到go-astilectron-demo目录，执行bundle命令。

astilectron-bundler -v

执行过程略漫长，然后在下载electron的时候会出错误。

PS C:\Users\Administrator\go\src\github.com\asticode\go-astilectron-demo> astile

PS C:\Users\Administrator\go\src\github.com\asticode\go-astilectron-demo>

解决方法：
分析命令行bundler的日志，可以发现，需要下载electron-v1.8.1-win32-x64.zip。
从日志中复制下载链接：
https://github.com/electron/electron/releases/download/v1.8.1/electron-v1.8.1-win32-x64.zip
把下载的文件重命名为日志中指定的文件名electron-windows-amd64-1.8.1.zip。
然后把文件放到下面目录中

C:\Users\Administrator\AppData\Local\Temp\astibundler\cache

再次执行bundler命令

astilectron-bundler -v

执行编译后的程序

bundler命令执行成功后，会在程序所在目录下生成下面的目录。
output/-
我的目录是

C:\Users\Administrator\go\src\github.com\asticode\go-astilectron-demo\output\windows-amd64

目录中的文件是编译好的文件，文件名是Astilectron demo.exe。
双击执行，大功告成！！
