如何使用Go在Windows上请求管理特权

Question

What I want to achieve for my application, is to not need to right click and choose Run as administrator each time I want to run it. I want Windows to prompt me to gain admin permissions as with other windows applications.

consider the following code:

package main

import (
    "fmt"
    "io/ioutil"
    "time"
)

func main() {
    err := ioutil.WriteFile("C:/Windows/test.txt", []byte("TESTING!"), 0644)
    if err != nil {
        fmt.Println(err.Error())
        time.Sleep(time.Second * 3)
    }
}

If you compile it and double click on it it will print:

open: C:\Windows\test.txt: Access is denied.

But if you right-click and run as administrator, it will create and write the file.

How to make it ask for the admin permission just by double clicking on it?

You need to embed a manifest file which will tell Windows that you want elevated privileges.

The example from that page is:

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<assembly xmlns="urn:schemas-microsoft-com:asm.v1" manifestVersion="1.0">
<assemblyIdentity
    version="9.0.0.0"
    processorArchitecture="x86"
    name="myapp.exe"
    type="win32"
/>
<description>My App</description>
<trustInfo xmlns="urn:schemas-microsoft-com:asm.v3">
    <security>
        <requestedPrivileges>
            <requestedExecutionLevel level="requireAdministrator" uiAccess="false"/>
        </requestedPrivileges>
    </security>
</trustInfo>
</assembly>

This go-nuts post suggests that using rsrc should do the trick for you.
