call_cmd.md

Windows下调用cmd.exe，并隐藏窗口

• 创建manifest文件, 命名：call_cmd.manifest

    <?xml version="1.0" encoding="UTF-8" standalone="yes"?>
    <assembly xmlns="urn:schemas-microsoft-com:asm.v1" manifestVersion="1.0">
    <assemblyIdentity
        version="1.0.0.0"
        processorArchitecture="x86"
        name="controls"
        type="win32"
    ></assemblyIdentity>
    <dependency>
        <dependentAssembly>
            <assemblyIdentity
                type="win32"
                name="Microsoft.Windows.Common-Controls"
                version="6.0.0.0"
                processorArchitecture="*"
                publicKeyToken="6595b64144ccf1df"
                language="*"
            ></assemblyIdentity>
        </dependentAssembly>
    </dependency>
    </assembly>
  

• 生成syso文件

  • 引入生成类库

      go get github.com/akavel/rsrc
    

  • 执行生成命令(准备ico文件)

      rsrc -manifest call_cmd.manifest -ico call_cmd.ico -o main.syso
    

• 将生成的main.syso文件拷贝到main.go同级目录

• main.go

    package main
    import(
        "fmt"
        "os/exec"
        "syscall"
    )
  
    func main(){   
        datapath := "http://172.18.1.12"
        cmd := exec.Command("cmd.exe", "/c", "start "+datapath)
        cmd.SysProcAttr = &syscall.SysProcAttr{HideWindow:true} //隐藏DOS窗口
        if err := cmd.Run(); err != nil {
            fmt.Println("Error: ", err)
        }  
    }
  

• 编译命令

    go build -ldflags -H=windowsgui
