我目前正在阅读Adam Freeman撰写的"Pro AngularJS".通过这些示例,他让读者使用Angular(当然)和Deployd服务器资源创建了一个体育商店应用程序.Deployd资源设置为返回要填充到模型中的JSON数据.我正在使用NodeJS来运行我的服务器.它目前在端口5000(http://localhost:5000/sportsstore/app.html)上设置.Deployd资源在端口5500(http://localhost:5500/products)上运行.点击Deployd时,响应如下:

我有一段 PowerShell 代码，它从 Azure 读取项目列表，并将它们格式化为一个表格供用户选择：

if ($SubscriptionArray.Count -eq 1) {
    $SelectedSub = 1
}
# Get SubscriptionID if one isn't provided
while ($SelectedSub -gt $SubscriptionArray.Count -or $SelectedSub -lt 1) {
    Write-host "Please select a subscription from the list below"
    $SubscriptionArray | Select-Object "#", Id, Name | Format-Table
    try {
        $SelectedSub = Read-Host "Please enter a selection from 1 to $($SubscriptionArray.count)"
    }
    catch {
        Write-Warning -Message 'Invalid option, please try again.'
    }
}

在脚本的主要区域中执行时，会输出预期的结果：

我想多次使用这个逻辑，因此将它移到一个方法中：

function Get-IndexNumberFromArray(
    [Parameter(Mandatory = $True)]
    [array]$selectArray, …

我在文本文件上使用File :: Find和file i/o来解析一系列目录并将内容移动到一个新文件夹中.这是一个简单的脚本(见下文):

#!/usr/bin/perl

use strict;
use warnings;
use File::Find;
use File::Copy;

my $dir = "/opt/CollectMinderDocuments/coastalalglive"; #base directory for Coastal documents

#read file that contains a list of closed IDs
open(MYDATA, "Closed.txt");

mkdir("Closed");

while(my $line = <MYDATA>) {
  chomp $line;
  my $str = "$dir" . "/Account$line";
  print "$str\n";
  find(\&move_documents, $str);
}
sub move_documents {
  my $smallStr = substr $File::Find::name, 43;
  if(-d) {
    #system("mkdir ~/Desktop/Closed/$smallStr");
    print "I'm here\n";
    system("mkdir /opt/CollectMinderDocuments/coastalalglive/Closed/$smallStr");
    #print "Made a directory: /opt/CollectMinderDocuments/coastalalglive/Closed/$smallStr\n";
  }
  else {
    print "Now …

我可以用一些帮助搞清楚为什么我的游戏不允许我拿起一把剑.出现的错误消息是

回溯(最近一次调用最后一次):文件"",第36行,在文件"",第1行,在NameError中:名称'y'未定义

这是基本游戏,我对此非常新,所以简单的术语会很好.
