getApplicationContext()方法未定义 - 片段问题

我收到以下错误:方法getApplicationContext()未定义方法findViewById(int)未定义类型Fragment1

当我的类扩展到一个Activity而不是片段时,这些错误似乎被消除了,但重要的是这个活动仍然是一个片段,所以我不太清楚如何解决这个问题.

任何帮助将不胜感激.提前致谢.

下面是代码

public class Fragment1 extends Fragment {

如何使用NodeJs的会话变量？

我有以下NodeJS代码:

  let sql = `SELECT box_id, cubby_id, occupied, comport
           FROM box
           WHERE longestDimension = ?
           AND LOWER(box_id) = LOWER(?)`;

    connection.query(sql, [boxSelectedDimension, boxSelectedValue] , function(err, rows, fields) {
        if (!err) {
            for(var i=0; i< rows.length; i++) {
                // Make the comparaison case insensitive
                if (rows[i].occupied == `unoccupied`) {
                    console.log("free");

                    var comport = rows[i].comport;
                    var command = "open" + rows[i].cubby_id;

本质上我想将comport和command变量的值存储在会话变量中,以便这些变量的值可以在nodejs中的另一个路由器页面中使用.

我不知道如何存储和检索会话变量.

如何在电子内运行快递？

我已经能够通过诸如的存储库在电子应用程序中成功运行express

https://github.com/theallmightyjohnmanning/electron-express

https://github.com/frankhale/electron-with-express

但是,由于他们施加的GNU通用公共许可证,我被告知不要这样做.我正在尝试创建一个可以货币化的商业应用.因此,像MIT这样的liscene可能会做,但不确定GNU.

无论如何,我一直在尝试遵循他的程序:https: //gist.github.com/maximilian-ruppert/a446a7ee87838a62099d

但是遇到了一些问题.这是迄今为止我所做的事情.
