从Linux迁移至Windows的Curl脚本适配问题求助

一、修复"Content-type not supported"错误 #

Linux下的curl命令在Windows cmd/PowerShell执行时，核心问题是引号语法差异：Windows cmd不识别单引号，必须用双引号包裹HTTP头参数。修正后的命令如下：

CMD环境适用 #

curl --connect-timeout 30 --max-time 60 -sk https://ssl.wsgc.com/vedsdk/Certificates/Retrieve -X POST -d @cert-retrieve-labtesttop.wsgc.com.json -H "Accept: application/json" -H "Content-Type: application/json" -H "Authorization: Bearer <Redacted>"

PowerShell环境适用 #

PowerShell会将@解析为变量符号，需给文件名添加额外引号：

curl --connect-timeout 30 --max-time 60 -sk https://ssl.wsgc.com/vedsdk/Certificates/Retrieve -X POST -d "@cert-retrieve-labtesttop.wsgc.com.json" -H "Accept: application/json" -H "Content-Type: application/json" -H "Authorization: Bearer <Redacted>"

二、改用文本文件作为请求体 #

请求体文件无需强制使用.json后缀，只要文件内容是合法JSON格式，直接用.txt文本文件即可。例如创建cert-request.txt，内容与原JSON文件完全一致，修改后的curl命令：

curl --connect-timeout 30 --max-time 60 -sk https://ssl.wsgc.com/vedsdk/Certificates/Retrieve -X POST -d @cert-request.txt -H "Accept: application/json" -H "Content-Type: application/json" -H "Authorization: Bearer <Redacted>"

注意：确保文本文件编码为UTF-8（无BOM），避免CA服务器解析JSON时出错。

三、批量处理1000+设备的脚本示例 #

Windows批处理脚本（CMD） #

假设你有devices.txt文件（每行一个设备域名，如labtesttop.wsgc.com），脚本会自动生成对应请求体并执行请求：

@echo off
setlocal enabledelayedexpansion

set DEVICE_LIST=devices.txt
set TEMPLATE_FILE=request-template.txt
set AUTH_TOKEN=<Redacted>

for /f "tokens=*" %%i in (%DEVICE_LIST%) do (
    set DEVICE=%%i
    :: 替换模板中的设备名生成请求体
    powershell -Command "(Get-Content %TEMPLATE_FILE%) -replace '{DEVICE_NAME}', '!DEVICE!' | Out-File -Encoding UTF8 'request-!DEVICE!.txt'"
    
    echo 正在请求!DEVICE!的证书...
    curl --connect-timeout 30 --max-time 60 -sk https://ssl.wsgc.com/vedsdk/Certificates/Retrieve -X POST -d @request-!DEVICE!.txt -H "Accept: application/json" -H "Content-Type: application/json" -H "Authorization: Bearer %AUTH_TOKEN%"
    
    del "request-!DEVICE!.txt"
)
endlocal

request-template.txt模板示例（替换为你的实际JSON结构）：

{
    "deviceName": "{DEVICE_NAME}",
    "certType": "server",
    "validityDays": 365
}

PowerShell批量脚本（更简洁） #

$deviceList = Get-Content "devices.txt"
$template = Get-Content "request-template.txt" -Raw
$authToken = "<Redacted>"
$caUrl = "https://ssl.wsgc.com/vedsdk/Certificates/Retrieve"

foreach ($device in $deviceList) {
    $requestBody = $template -replace "{DEVICE_NAME}", $device
    Write-Host "处理设备：$device"
    # 直接传递字符串请求体，无需临时文件
    curl --connect-timeout 30 --max-time 60 -sk $caUrl -X POST -d $requestBody -H "Accept: application/json" -H "Content-Type: application/json" -H "Authorization: Bearer $authToken"
}
