如何发送包含来自文件的数据的 JSON 正文的 Invoke-WebRequest

How to send Invoke-WebRequest with JSON body containing data from File

问题:
如何在没有不需要的文件元数据的情况下将文件内容放入 Invoke-WebRequest 的 JSON 主体中?

我的目标是像这样发送 HTTP 请求:

Invoke-WebRequest -Uri http://localhost:4321/updatefile `
    -ContentType 'application/json' `
    -Method POST `
    -Body $Body

其中:

PS C:\Users\User1234> $Body = ConvertTo-Json @(
    @{filename='file1.txt';filecontent=$file1},
    @{filename='file2.txt';filecontent=$file2}
)

PS C:\Users\User1234> $file1 = Get-Content "C:\path\to\file1.txt"
PS C:\Users\User1234> $file2 = Get-Content "C:\path\to\file2.txt"

当我打印变量时:

PS C:\Users\User1234> echo $file1
aaaaa
PS C:\Users\User1234> echo $file2
bbbbb

...它按我的预期打印文件的内容。
但是在 $Body 中打印文件内容会显示更多我不需要的信息:

PS C:\Users\User1234> echo $Body
{
    "filename":  "file1.txt",
    "filecontent":  {
                        "value":  "aaaaa",
                        "PSPath":  "C:\path\to\file1.txt",
                        "PSParentPath":  "C:\path\to",
                        "PSChildName":  "file1.txt",
                        "PSDrive":  {
                                        "CurrentLocation":  "Users\User1234",
                                        "Name":  "C",
                                        "Provider":  "Microsoft.PowerShell.Core\FileSystem",
                                        "Root":  "C:\",
                                        "Description":  "OS",
                                        "MaximumSize":  null,
                                        "Credential":  "System.Management.Automation.PSCredential",
                                        "DisplayRoot":  null
                                    },
                        "PSProvider":  {
                                           "ImplementingType":  "Microsoft.PowerShell.Commands.FileSystemProvider",
                                           "HelpFile":  "System.Management.Automation.dll-Help.xml",
                                           "Name":  "FileSystem",
                                           "PSSnapIn":  "Microsoft.PowerShell.Core",
                                           "ModuleName":  "Microsoft.PowerShell.Core",
                                           "Module":  null,
                                           "Description":  "",
                                           "Capabilities":  52,
                                           "Home":  "C:\Users\User1234",
                                           "Drives":  "C D Y"
                                       },
                        "ReadCount":  1
                    }
}

我尝试使用以下方法设置 $file1$file2 值:

$file1 = [IO.File]::ReadAllText("C:\path\to\file1.txt")    
$file2 = [IO.File]::ReadAllText("C:\path\to\file2.txt")

...但结果是一样的

首先设置$body,然后转换为json。

$body = @(
    @{
        filename = 'file1.txt'
        filecontent = [io.file]::ReadAllText("1.txt")
    }
)

$body | ConvertTo-Json

$body = @(
    @{
        filename = 'file1.txt'
        filecontent = (get-content 1.txt) -join "`r`n"
    }
)

$body | ConvertTo-Json

输出

{
    "filename":  "file1.txt",
    "filecontent":  "1\r\n2\r\n3\r\n"
}

原因很简单,get-content returns 一个数组,convertto-json 完成了它的工作,但可能不是你所期望的。
