[问题求助] powershell调用ddddocr

小白龙

刚刚发现一个专门识别验证码的免费开源项目 ddddocr, 开源项目地址如下：
https://github.com/86maid/ddddocr

下载地址如下：
https://github.com/86maid/ddddoc ... pc-windows-msvc.zip

我用命令行把服务启动起来后，然后用powershell调用，但总是识别输出为空，求路过大佬支招， 多谢

下面代码是GPT帮写的，不报错，但是输出为空，截图如下：

#先手动下面的命令启动服务
#ddddocr.exe -a 127.0.0.1 -p 9898 --ocr

# 设置服务器地址和图片路径
$hostUrl = "http://127.0.0.1:9898/ocr/file/text"
$imagePath = "$PSScriptRoot\test1.png"

# 检查图片文件是否存在
if (-Not (Test-Path -Path $imagePath)) {
    Write-Output "图片文件未找到: $imagePath"
    return
}

# 读取图片文件内容
$fileBytes = [System.IO.File]::ReadAllBytes($imagePath)

# 准备 multipart/form-data 请求
$boundary = [System.Guid]::NewGuid().ToString()
$formData = @"
--$boundary
Content-Disposition: form-data; name="image"; filename="test.png"
Content-Type: image/png

$fileBytes
--$boundary--
"@

try {
    # 发送 POST 请求
    $response = Invoke-RestMethod -Uri $hostUrl -Method Post -ContentType "multipart/form-data; boundary=$boundary" -Body ([System.Text.Encoding]::UTF8.GetBytes($formData))
    Write-Output "识别结果: $response"
} catch {
    Write-Output "请求失败，错误信息: $_"
}
