如何通过PowerShell将用户输入传入JSON并生成用户名命名的JSON文件

直接先获取用户输入，再动态填充哈希表的对应字段，就能解决参数传递的问题。完整脚本如下：

# 1. 获取用户输入
$inputUsername = Read-Host "请输入用户名"
$inputIpAddress = Read-Host "请输入IP地址"
$inputPassword = Read-Host "请输入密码"  # 如果需要隐藏输入，改用 Read-Host "请输入密码" -AsSecureString 再转成明文

# 2. 构建带动态参数的哈希表
$body = @{
    devices = @(
        @{ 
            credentials = @(
                @{
                    label = 'username'
                    value = $inputUsername
                    sensitive = 'false'
                },
                @{
                    label = 'Password'
                    value = $inputPassword
                    sensitive = 'true'
                }
            )
            services = @(
               @{
                    name = 'RDP'
                    url = "https://$inputIpAddress/?pauth=[proxy_token]&data=[connection:$inputUsername]"
                    instructor = 'false'
                },
               @{
                    name = 'HTTPS'
                    url = "https://$inputIpAddress/?pauth=[proxy_token]&data=[connection:$inputUsername]"
                    instructor = 'false'
                },
               @{
                    name = 'SSH'
                    url = "https://$inputIpAddress/?pauth=[proxy_token]&data=[connection:$inputUsername]"
                    instructor = 'false'
                 }
            )
            connections = @(
                @{
                    id = "$inputUsername-rdp"
                    protocol = 'rdp'
                    hostname = $inputIpAddress
                    port ='3389'
                }
                )
               Parameters = @( 
               @{
                    name = 'username'
                    value = $inputUsername
                },
                @{
                    name = 'password'
                    value = $inputPassword
                }
            )
        }
    )
}

# 3. 转换为JSON并保存
$body | ConvertTo-Json -Depth 4 | Out-File "$inputUsername.json" -Encoding UTF8

关键说明： #

• 先通过Read-Host获取输入并赋值给变量，再把这些变量直接嵌入哈希表的对应位置，避免后续替换的麻烦
• 注意connections里的id字段需要拼接用户名，用双引号包裹字符串才能解析变量
• 保存文件时直接用用户名作为文件名，确保每次生成的文件对应当前输入的用户
• 如果需要安全处理密码，用-AsSecureString获取加密输入，再通过[System.Net.NetworkCredential]转换为明文填入哈希表

如果你坚持要先定义固定结构的哈希表再替换，也可以这么做：

# 先获取输入
$inputUsername = Read-Host "请输入用户名"
$inputIpAddress = Read-Host "请输入IP地址"
$inputPassword = Read-Host "请输入密码"

# 定义基础哈希表
$body = @{
        devices = @(
            @{ 
                credentials = @(
                    @{
                        label = 'username'
                        value = 'myname'
                        sensitive = 'false'
                    },
                    @{
                        label = 'Password'
                        value = 'Password@!'
                        sensitive = 'true'
                    }
                )
                services = @(
                   @{
                        name = 'RDP'
                        url = "https://$inputIpAddress/?pauth=[proxy_token]&data=[connection:$inputUsername]"
                        instructor = 'false'
                    },
                   @{
                        name = 'HTTPS'
                        url = "https://$inputIpAddress/?pauth=[proxy_token]&data=[connection:$inputUsername]"
                        instructor = 'false'
                    },
                   @{
                        name = 'SSH'
                        url = "https://$inputIpAddress/?pauth=[proxy_token]&data=[connection:$inputUsername]"
                        instructor = 'false'
                     }
                )
                connections = @(
                    @{
                        id = 'myname-rdp'
                        protocol = 'rdp'
                        hostname = "192.168.1.6"
                        port ='3389'
                    }
                    )
                   Parameters = @( 
                   @{
                        name = 'username'
                        value = 'myname'
                    },
                    @{
                        name = 'password'
                        value = 'Password@!'
                    }
                )
            }
        )
    }

# 逐个替换字段
$body.devices[0].credentials[0].value = $inputUsername
$body.devices[0].credentials[1].value = $inputPassword
$body.devices[0].connections[0].hostname = $inputIpAddress
$body.devices[0].connections[0].id = "$inputUsername-rdp"
$body.devices[0].Parameters[0].value = $inputUsername
$body.devices[0].Parameters[1].value = $inputPassword

# 生成并保存JSON
$body | ConvertTo-Json -Depth 4 | Out-File "$inputUsername.json" -Encoding UTF8

这种方式适合需要保留基础模板结构的场景，通过索引定位到哈希表的嵌套节点进行值替换。
