Question

我正在尝试使用以下代码来运行“噩梦”脚本，以进行屏幕截图： “ usr.dir”包含直到“ \ src \ ....”的路径。

String root = System.getProperty("usr.dir");
String screenshotJS = "node " + root + "\\src\\main\\resources\\screenshot.js";
try {

  File tempFile = File.createTempFile(root, ".png");

  Process p = Runtime.getRuntime().exec(screenshotJS + " " + url + " " + tempFile.toString());

  p.waitFor();

  int exitCode = p.exitValue();
  if (exitCode != 0) {
    System.out.println("Error Execute when exitCode=1");
  }else{
    System.out.println("Fine Execute when exitCode=0");
    }

  BufferedImage bufferedImage = new BufferedImage(
          500, 500, BufferedImage.TYPE_INT_RGB );
  File outputfile = new File(tempFile.getName());
  ImageIO.write(bufferedImage, "png", outputfile);
  return tempFile.getName();

梦m脚本：

    const nightmare = require('nightmare')();
    nightmare
   .goto(process.argv[2])
   .viewport(1152, 864)
   .screenshot(process.argv[3] || 'screenshot.png')
   .end(() => {});

该过程的返回值为1。我做错了什么？有人可以协助我处理此案吗？

谢谢

伊多
