</html>。我想过滤掉这些数据。由于您可以将exec.Command编写器设置为stdout结构，我的想法是编写一个自定义Command，它基本上消耗输出并按给定的单词过滤输出。
io.Writer我不确定我是否会以正确的方式前往这里，但我确信我可以在某种程度上重复使用现有的type passwordFilter struct {
keyWord string
}
func (pf passwordFilter) Write(p []byte) (n int, err error) {
// this is where I have no idea what to do
// I think I should somehow use a scanner and then filter
// out = strings.Replace(out, pf.keyWord, "*******", -1)
// something like this
// but I have to deal with byte array here
}
func main() {
pf := passwordFilter{keyWord: "password123"}
cmd := exec.Command(someBinaryFile)
cmd.Stdout = pf
cmd.Stderr = &stderr
if err := cmd.Run(); err != nil {
log.Fatal(err)
}
}
或扫描仪。
答案 0 :(得分：3)
使用Cmd.StdoutPipe让读者了解程序输出。在该阅读器上使用扫描仪。
cmd := exec.Command(someBinaryFile)
r, err := cmd.StdoutPipe()
if err != nil {
log.Fatal(err)
}
if err := cmd.Start(); err != nil {
log.Fatal(err)
}
s := bufio.NewScanner(r)
for s.Scan() {
out := s.String()
out = strings.Replace(out, pf.keyWord, "*******", -1)
// write out to destination
}
if s.Err() != nil {
log.Fatal(s.Err())
}
if err := cmd.Wait(); err != nil {
log.Fatal(err)
}
