一: 提要:
参考项目:
https://github.com/Zzaphkiel/Seraphine
想做一个 lol 查战绩的软件,并且满足自己的需求(把混子和大爹都表示出来),做的第一步就是获取 lcu token ,网上清一色的使用 wmic 去查询的,这样也不是不行,不过需要使用管理员权限,恰好我在用Seraphine,发现别人根本不需要管理员权限就可以获取
但是我在全网并没有找到其他的实现,就自己研究了一下,发现谜底就在获取 token 的方式上。
二:获取过程:
wmic PROCESS WHERE name='LeagueClientUx.exe' GET commandline
一般来说其他进程的详细数据是敏感信息,如果没有管理员权限,不能随便访问。如上述代码 wmic 只能有管理员才能访问,但是 commandline 又不是非常敏感的数据,
这里最后是通过 windows api进行交互,理论上说,大部分编译型语言都没问题,这里给到go的演示
package mainimport ("fmt""golang.org/x/sys/windows""log""os/exec""strconv""strings""unsafe"
)func getProcessPidByName(name string) ([]int, error) {cmd := exec.Command("wmic", "process", "where", fmt.Sprintf("name like '%%%s%%'", name), "get", "processid")output, err := cmd.CombinedOutput()if err != nil {return nil, err}// 将输出按行分割lines := strings.Split(string(output), "\n")var pids []int// 处理每行输出for _, line := range lines {trimmed := strings.TrimSpace(line)if len(trimmed) > 0 {// 转换为数字并添加到结果中pid, err := strconv.Atoi(trimmed)if err == nil {pids = append(pids, pid)}}}return pids, nil
}const (ProcessCommandLineInformation = 60PROCESS_QUERY_LIMITED_INFORMATION = 0x1000
)var (modntdll = windows.NewLazySystemDLL("ntdll.dll")procNtQueryInformationProcess = modntdll.NewProc("NtQueryInformationProcess")
)type UNICODE_STRING struct {Length uint16MaximumLength uint16Buffer *uint16
