我正在尝试使用 phantomJS(顺便说一句,多么棒的工具!)为我有登录凭据的页面提交表单,然后将目标页面的内容输出到标准输出。我能够使用 phantom 成功访问表单并设置其值,但我不太确定提交表单并输出后续页面内容的正确语法是什么。到目前为止我所拥有的是:
var page = new WebPage();
var url = phantom.args[0];
page.open(url, function (status) {
  if (status !== 'success') {
      console.log('Unable to access network');
  } else {
    console.log(page.evaluate(function () {
      var arr = document.getElementsByClassName("login-form");
      var i;
      for (i=0; i < arr.length; i++) {
        if (arr[i].getAttribute('method') == "POST") {
          arr[i].elements["email"].value="mylogin@somedomain.com";
          arr[i].elements["password"].value="mypassword";
          // This part doesn't seem to work. It returns the content
          // of the current page, not the content of the page after 
          // the submit has been executed. Am I correctly instrumenting
          // the submit in Phantom?
          arr[i].submit();
          return document.querySelectorAll('html')[0].outerHTML;
        }
      }
      return "failed :-(";
    }));
  }
  phantom.exit();
}
