2019独角兽企业重金招聘Python工程师标准>>>

重写window.onerror方法，将前端错误信息封装到一个get请求中。通过Image发送到服务端

  window.onerror = function(errorMessage, url, line) {
  var loggerUrl = "https://www.buglife.cn/js/logger";
  var parameters = "?description=" + escape(errorMessage)
      + "&url=" + escape(url)
      + "&line=" + escape(line)
      + "&parent_url=" + escape(document.location.href)
      + "&user_agent=" + escape(navigator.userAgent);

  /** Send error to server */
  new Image().src = loggerUrl + parameters;
  };
