# 本地文件路径
$FilePath = 'c:\Users\Administrator\Desktop\import.doc';
# 服务器保存的文件名
$FieldName = 'import.doc' ;
$URL = 'http://192.168.164.141/upload.php';  
# 换行符
$LF = "`r`n";

# boundary标记，用于区分多个文件
$boundary = [System.Guid]::NewGuid().ToString(); 
$ContentType = 'multipart/form-data; charset=utf-8; boundary='+$boundary;

# 读取本地文件
$File =[System.IO.File]::ReadAllBytes($FilePath);

# 编码器，用于将boundary等信息转为字节
$enc=[System.Text.Encoding]::GetEncoding('UTF-8');
# 拼接boundary与文件字节
[byte[]]$Body = $enc.GetBytes("--$boundary"+$LF+"Content-Disposition: form-data; name='file'; filename="+$FieldName+$LF+"Content-Type: application/octet-stream"+$LF+$LF);
[byte[]]$Body +=$File
[byte[]]$Body += $enc.GetBytes($LF+"--"+$boundary+"--"+$LF);

# $Body为字节数组时，即为发送数据流
Invoke-WebRequest -Uri $URL -Method Post -ContentType $ContentType -Body $Body ;
