如何使用Invoke-RestMethod上传jpg [英] How to use Invoke-RestMethod to upload jpg

问题描述

我正在尝试使用 PowerShell commandlet Invoke-RestMethod 将图片发布到 url.这是我的命令:

I'm trying to use the PowerShell commandlet Invoke-RestMethod to post a picture to a url. Here's my commands:

$usercreds = Get-Credential
$pic = Get-Content \\server\share\pic.jpg
$uri = http://website/sub/destination

Invoke-RestMethod -uri $uri -Method Put -Body $pic -ContentType 'image/jpg' -Credential $usercreds

出现错误:该文件不是有效的图像文件."我也尝试使用 Invoke-WebRequest，结果相同.Web 服务器不是我们的，他们方面的技术人员说使用 curl，但我们不知道如何使用，也没有 Linux 机器.有什么我想念的吗?我可以毫无问题地打开 jpg，所以它没有损坏或任何东西.

I get an error: "the file is not a valid image file." I tried using Invoke-WebRequest too, with the same result. The web server isn't ours, and the tech on their side said to use curl, but we don't know how and don't have a Linux box either. Is there something I'm missing? I can open the jpg without issue so it's not corrupt or anything.

我试过了，但服务器对我大喊:使用 PowerShell Invoke-RestMethod POST 大型二进制 multipart/form-data

I tried this, but the server yelled at me: Using PowerShell Invoke-RestMethod to POST large binary multipart/form-data

错误代码:

PS C:\Windows\system32> Invoke-WebRequest -uri $uri -Method Put -Body $pic -ContentType 'image/jpg' -Credential $usercreds
Invoke-WebRequest : {"error":{"message":"the file is not a valid image file"},"data":[],"meta":"error"}

推荐答案

尝试使用 -Infile 参数.Get-Content 将您的文件解释为一个字符串数组，只会把事情搞砸.

Try using the -Infile Parameter. Get-Content interprets your file an array of strings and just messes things up.

$usercreds = Get-Credential
$picPath = "\\server\share\pic.jpg"
$uri = http://website/sub/destination

Invoke-WebRequest -uri $uri -Method Put -Infile $picPath -ContentType 'image/jpg' -Credential $usercreds
