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
和 $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
或
$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。
