我有以下尝试在Linux OS上运行的代码。我手动运行curl命令，它按预期返回了响应，但是当我尝试通过Java运行时，它失败了，Process.waitFor（）返回了非零值。
码：
public static String runShellCmd(String url)throws Exception
{
String key="i_testonia";
String value="i_dba@088922";
String result="";
try
{
// String[] command = {"curl","-k", "-i" ,"-X", "GET" ,"-H", "Accept:application/json", "-u", key.trim()+":"+value.trim() , url};
//ProcessBuilder process = new ProcessBuilder(command);
ProcessBuilder process = new ProcessBuilder();
process.command("bash","-c","curl -k -i -u i_testonia:i_dba@088922 -XGET "+url);
Process p;
try
{
p = process.start();
BufferedReader reader = new BufferedReader(new InputStreamReader(p.getInputStream()));
StringBuilder builder = new StringBuilder();
String line = null;
while ( (line = reader.readLine()) != null) {
builder.append(line);
builder.append(System.getProperty("line.separator"));
}
result+=builder.toString();
System.out.print(result);
int exitVal = p.waitFor();
if (exitVal == 0) {
System.out.println("Success!");
System.out.println(result);
System.exit(0);
} else {
//abnormal...
System.out.println("Failed and"+exitVal ); // return 1 as output
}
}
catch (IOException e)
{ System.out.print("error");
e.printStackTrace();
}
}
catch(Exception ex)
{
ex.printStackTrace();
}
return result;
}
当我在linux框中运行上述代码并查看result.length（）返回0时，p.waitFor（）返回1作为值。
有人可以让我知道上面代码中缺少的内容吗？我只是在终端中运行curl命令，可以看到响应JSON。但是它不能通过JAVA工作。
我尝试使用1）processBuilder.command（“”）以及2）创建String []并将该值传递给ProcessBuilder构造函数（//在上面的示例中注释那些代码）。这两个选项均无效。
