请问一下： 1、在Electron中，是否默认情况下，一般都是只有一个window？ const mainWindow = new BrowserWindow({...}) 2、在什么场景下，使用多个window呢？ 3、是否在Electron创建项目之后，默认情况下，是渲染进程上嵌入的一个SPA应用？

我不希望 git 记录 npz 结尾的文件 所以我在 ".gitignore" 里面添加了 "*.npz" 但是呢，我并不是所有的 npz 都想忽略 我想让 git 只追踪 "testing/std.npz" 如何声明让 git 忽略除了 "testing/std.npz" 之外的所有 npz 文件呢？

DRM 是给源文件加密，通过密钥解密播放。 那么在客户端就会有文件+密钥，既然客户端能解密，那么所有人都能解密，不就不安全了吗？所以他是如何保证安全的。 是不是可以通过转录，比如说 Web mediaSource 之类的东西直接把解密后的就存了？

可以使用工具类型 "Omit" 将需要修改的属性 "measure_value" 剔除掉，然后继承剔除后的接口，并对该属性进行重新声名。（PS：如下代码中，我将原接口的属性改成可选属性，以避免赋值时的报错。） export interface ITableData { flag?: 0 | 1; measure_name?: string; measure_value?: number; result_desc?: string; standard_deviation?: number; standard_value?: number; name?: string; } interface IMeasureData extends Omit { measure_value: number | string; } const measureList: IMeasureData[] = [{ measure_value: "2" }]; 希望对题主有所帮助！

They have three read-only attributes:* "partial.func" A callable object or function. Calls to the partial object will be forwarded to func with new arguments and keywords. * "partial.args" The leftmost positional arguments that will be prepended to the positional arguments provided to a partial object call. * "partial.keywords" The keyword arguments that will be supplied when the partial object is called.» «partial objects are like function objects in that they are callable, weak referencable, and can have attributes. There are some important differences. For instance, the "__name__" and "__doc__" attributes are not created automatically. Also, partial objects defined in classes behave like static methods and do not transform into bound methods during instance attribute look-up.»

用 responseStatus 属性: const observer = new PerformanceObserver((list) => { list.getEntries().forEach((entry) => { if (entry.responseStatus === 304) { console.log(`${entry.name} was loaded from cache`); } }); }); observer.observe({ type: "resource", buffered: true }); 或者用 transferSize 属性可以用来检查本地缓存有没有命中，如果 transferSize 的值为 0，就表示资源是从缓存加载的，不是从网络加载的

2023 年了，用 "async/await" 吧，在异步操作前加一个 "await"，再把自己的函数前加一个 "async"，剩下的就跟写同步函数差不多。 async mounted() { // 这里最好加一个错误处理，网络请求很容易出错 const data = await axios.get('....'); this.userData = data; // 后面也不要再手动操作 dom 了，直接写成模版吧 }

[Vue]父组件A通过props传入子组件B一个函数f，子组件B想要执行f(null,B的一个data)，并判断f中是否用到了第一个参数（通过try catch），如果用到了，再将f通过props传入孙组件C；否则将执行结果传入C？ 父组件A中： data() { return { f(p1, p2) } } 子组件B中： computed: { B_f(){ if 没有用到C的data return f(null, 自己的一个data){...} else return f } } 孙组件C中： ...C_f... computed: { C_f(){ return f(自己的一个data){...} } } 目的是 1在组件A里定义一个函数f(参数1为子组件B的一个data，参数2为孙组件C的一个data) 2不能修改孙组件C的代码 这个逻辑看着有点别扭，有什么更好的实现方式

1. 大体上没问题 2. pnpm 因为依赖树解析的问题，不支持直接使用“依赖的依赖”，即 A 依赖 B，你安装了 A，可以使用 A，但是不能直接使用 B 3. 所以最好的办法就是每个项目里单独安装一份 vue、vue-router 等 4. 不过不用担心，pnpm 使用硬链接，所以不存在重复下载和安装的问题

这个根据业务决定，你可问问你们后端，同时方法二也可以创建一个新的 axios 实例进行拓展啊，这种不需要考虑太多，两种都具备向后拓展的空间

大括号不匹配。第一个 if 右边的大括号没有写。

在 vue3.0 + typescript 项目中引入 @antv 报错，查看报错信息，原因是因为在 @antv 中使用了 ?? 和?. 的语法导致报错，尝试了多种方案，使用 babel 等，均未解决这个报错的问题。请问这个如何在 vue.config.js 中配置呢？ 报错信息如下所示： "image.png" (https://wmprod.oss-cn-shanghai.aliyuncs.com/c/user/20241009/e476c25699d19973e065d44888e943a8.png)

现在在编写一个脚本，希望在root用户下收集oracle用户下的一些信息，但是发现在脚本中切换用户执行命令会出现环境变量问题。 [root@oracle01 ~]# su - oracle -c "$ORACLE_HOME/OPatch/opatch lsinventory" -bash: /OPatch/opatch: No such file or directory [root@oracle01 ~]# su - oracle -c "echo $ORACLE_HOME" [root@oracle01 ~]# 如上面的命令所示，ORACLE_HOME是个空。 oracle用户下确实设置了环境变量，但是使用su - oracle -c "echo $ORACLE_HOME"这种样子查看时却显示该变量为空。 要如何才能在切换oracle用户后正确使用$ORACLE_HOME变量呢？ [root@oracle01 ~]# su - oracle Last login: Wed Mar 13 16:20:05 CST 2024 on pts/0 [oracle@oracle01 ~]$ cat ~/.bash_profile ...省略一些输出 export ORACLE_BASE=/u01/app/oracle export ORACLE_HOME=$ORACLE_BASE/product/11.2.0/db_1 ...省略一些输出 [oracle@oracle01 ~]$ echo $ORACLE_HOME /u01/app/oracle/product/11.2.0/db_1 [oracle@oracle01 ~]$ exit logout [root@oracle01 ~]# [root@oracle01 ~]# su - oracle -c "env|grep ORACLE_HOME" ORACLE_HOME=/01/app/oracle/product/11.2.0/db_1 [root@oracle01 ~]# su - oracle -c "echo $ORACLE_HOME" [root@oracle01 ~]#
