从REST API调用，我尝试使用以下代码将响应存储在csv中

$response = Invoke-RestMethod 'http://api.ipstack.com/54.251.51.24?access_key=mykey&security=1&hostname=1' -Method 'GET' -Headers $headers |
    Select-Object ip,hostname -ExpandProperty time_zone |
    Select-Object ip,hostname,@{N='time_zone_code';E={$_.code}} -ExpandProperty location |
    Select-Object ip,hostname,time_zone_code,@{N='location_geoname_id';E={$_.geoname_id}} -ExpandProperty languages |
    Select-Object ip,hostname,location_geoname_id,time_zone_code,@{N='languages_native';E={$_.native}} |
        Export-Csv C:\Users\Lenovo\Desktop\Danial\response.csv -NoTypeInformation -Append

它给我下面的错误

Select-Object : Property "location" cannot be found.
At line:3 char:9
+         Select-Object ip,hostname,@{N='time_zone_code';E={$_.code}} - ...
+         ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
    + CategoryInfo          : InvalidArgument: (@{id=Australia/...e=1.132.104.84}:PSObject) 
[Select-Object], PSArgumentException
    + FullyQualifiedErrorId : 
ExpandPropertyNotFound,Microsoft.PowerShell.Commands.SelectObjectCommand

我尝试了很多东西，但不知道如何在Select-Object中扩展多个属性。

{
    "ip": "54.251.51.24",
    "hostname": "54.251.51.24",
    "type": "ipv4",
    "continent_code": "OC",
    "continent_name": "Oceania",
    "country_code": "AU",
    "country_name": "Australia",
    "region_code": "QLD",
    "region_name": "Queensland",
    "city": "Brisbane",
    "zip": "4000",
    "latitude": -27.467580795288086,
    "longitude": 153.02789306640625,
    "location": {
        "geoname_id": 2174003,
        "capital": "Canberra",
        "languages": [
            {
                "code": "en",
                "name": "English",
                "native": "English"
            }
        ],
        "country_flag": "https://assets.ipstack.com/flags/au.svg",
        "country_flag_emoji": "🇦🇺",
        "country_flag_emoji_unicode": "U+1F1E6 U+1F1FA",
        "calling_code": "61",
        "is_eu": false
    },
    "time_zone": {
        "id": "Australia/Brisbane",
        "current_time": "2023-03-07T18:54:34+10:00",
        "gmt_offset": 36000,
        "code": "AEST",
        "is_daylight_saving": false
    }
}

我想将csv中location和time_zone的所有列存储为可读，而不是System.Object

简单地从数据行创建新对象并导出这些对象可能比使用Select-Object更容易：
1.设置一些测试数据

$json = @"
{
    "ip": "54.251.51.24",
    "hostname": "54.251.51.24",
    "type": "ipv4",
    "continent_code": "OC",
    "continent_name": "Oceania",
    "country_code": "AU",
    "country_name": "Australia",
    "region_code": "QLD",
    "region_name": "Queensland",
    "city": "Brisbane",
    "zip": "4000",
    "latitude": -27.467580795288086,
    "longitude": 153.02789306640625,
    "location": {
        "geoname_id": 2174003,
        "capital": "Canberra",
        "languages": [
            {
                "code": "en",
                "name": "English",
                "native": "English"
            }
        ],
        "country_flag": "https://assets.ipstack.com/flags/au.svg",
        "country_flag_emoji": "🇦🇺",
        "country_flag_emoji_unicode": "U+1F1E6 U+1F1FA",
        "calling_code": "61",
        "is_eu": false
    },
    "time_zone": {
        "id": "Australia/Brisbane",
        "current_time": "2023-03-07T18:54:34+10:00",
        "gmt_offset": 36000,
        "code": "AEST",
        "is_daylight_saving": false
    }
}
"@

$data = $json | ConvertFrom-Json;

1.将数据格式化为CSV友好的格式

$formatted = $data | foreach-object {
    [pscustomobject] [ordered] @{
        "HostName" = $_.hostname
        "Capital"  = $_.location.capital
        "Timezone" = $_.time_zone.code
    }
}

# show the data for reference:
$formatted | format-table

# HostName     Capital  Timezone
# --------     -------  --------
# 54.251.51.24 Canberra AEST

1.转换格式化的数据（如果要保存到磁盘，请使用Export-Csv）：

$formatted | ConvertTo-Csv

# "HostName","Capital","Timezone"
# "54.251.51.24","Canberra","AEST"

访问location时出现错误，因为您已经在此处删除了此属性：
Select-Object ip,hostname -ExpandProperty time_zone |
将您将要使用的属性添加到所有前面的select-object中

使用以下代码解决了我的问题

$properties=@('ip','hostname'
    @{Name='time_zone_code';Expression={$_.time_zone.code}}
    @{Name='location_geoname_id';Expression={$_.location.geoname_id}}
    @{Name='location_languages_native';Expression={$_.location.languages.native}}
)
$response = Invoke-RestMethod 'http://api.ipstack.com/54.251.51.24?access_key=mykey&security=1&hostname=1' -Method 'GET' -Headers $headers |
    Select-Object -Property $properties |
        Export-Csv C:\Users\Lenovo\Desktop\Danial\response.csv -NoTypeInformation -Append
