Hi:
I tried std::process::Command today.it is good.
use std::process::Command;
fn main() {
let output = Command::new("ipconfig")
.arg("/all")
.output().unwrap_or_else(|e| {
panic!("failed to execute process: {}", e)
});
if output.status.success() {
let s = String::from_utf8_lossy(&output.stdout);
print!("rustc succeeded and stdout was:\n{}", s);
} else {
let s = String::from_utf8_lossy(&output.stderr);
print!("rustc failed and stderr was:\n{}", s);
}
}
but I meet a problem with character sets. my Windows system language is not english. I think the cmd character set should be GBK, not utf8. so some results seems as black squares, or gibberish.
I also searched for java solution. the Charset.forName can slove that confuse like the code below.
my questions : is there a function or cfg for command function for that purpose or I should change to another way?:grinning:
public static void main(String[] args) {
try {
// 执行ping命令
Process process = Runtime.getRuntime().exec("cmd /c e:&dir");
BufferedReader br = new BufferedReader(new InputStreamReader(process.getInputStream(), Charset.forName("GBK")));
String line = null;
while ((line = br.readLine()) != null) {
System.out.println(line);
}
} catch (IOException e) {
e.printStackTrace();
}
}
