点击按钮后用PHP向Azure DevOps提交JSON数据报错求助

我正尝试向Azure DevOps提交JSON数据创建变量组，已编写并验证可用的PowerShell代码，但编写的PHP代码运行时出现致命错误。

可用的PowerShell代码 #

$organization = "DevOpsOrg"
$project = "Worldhealthgroup"
$url_base = "https://dev.azure.com/$organization/$project/"
$url_endpoint = "_apis/distributedtask/variablegroups?api-version=6.0-preview.2"
$url = $url_base + $url_endpoint

$pat = "xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx"
$token =[System.Convert]::ToBase64String([System.Text.Encoding]::ASCII.GetBytes(":$($pat)"))

$JSON = @'
{
    "description": "TestVariableGroup",
    "name": "TestVariableGroup",
    "providerData": null,
    "type": "Vsts",
    "variables": {"applicationID": {

        "isSecret": false,

$response = Invoke-RestMethod -Uri $url -Headers @{Authorization = "Basic $token"} -Method Post -ContentType application/json -body $JSON

报错信息 #

Fatal error: Uncaught Error: Call to undefined function curl_setpot() in C:\xampp\htdocs\restapi2\devopspost.php

解决步骤 #

1. 修正函数拼写错误：将代码中两处curl_setpot改为正确的curl_setopt，这是导致致命错误的直接原因。
2. 补充语句结束符：PHP每条语句必须以分号结尾，给前几行变量赋值添加分号：

   $organization = "DevOpsOrg";
   $project = "Worldhealthgroup";
   $url_base = "https://dev.azure.com/$organization/$project/";
   $url_endpoint = "_apis/distributedtask/variablegroups?api-version=6.0-preview.2";
   

3. 移除错误请求头：删除content-length: 0这个请求头，否则Azure DevOps无法正确解析提交的JSON内容。
4. 完善请求执行流程：添加curl执行和关闭代码，同时增加错误处理：

   $response = curl_exec($ci);
   if(curl_errno($ci)) {
       echo '请求错误: ' . curl_error($ci);
   } else {
       echo $response;
   }
   curl_close($ci);
