在MS Access中将CURL请求转换为VBA xml对象

我正在尝试使用VBA代码处理我们学校MS Access数据库中的moodle数据，以发布xml.objects。 我从一个将RESTful API用于VBA代码的示例中实现了以下代码（源代码）：

json代码：

curl -X POST \
-H "Content-Type: application/json" \
-H "Accept: application/json" \
-H 'Authorization: {token}' \
-d'{"options": {"ids":[6]}}' \
"https://localhost/webservice/restful/server.php/core_course_get_courses"

这是我目前在ms access db模块中用VBA进行的转换：

Option Compare Database
Option Explicit

Private Sub btnTestMoodleApi_Click()

Dim objRequest As Object
Dim strResult As String
Dim strPostData As String
Dim strToken as String
Dim strURL as String

strToken = xxx
strURL = xxx

Set objRequest = CreateObject("MSXML2.XMLHTTP")

strPostData = "'options[ids][0]=8'" 

With objRequest
  .Open "POST", strURL & "/webservice/restful/server.php/core_course_get_courses"
  .setRequestHeader "Authorization", strToken
  '  .setRequestHeader Chr(34) & "Authorization" & Chr(34), Chr(34) & EncodeBase64(strToken) & Chr(34) ' is any of this necessary? I also tried single quotes chr(39)

  .setRequestHeader "Content-Type", " application/x-www-form-urlencoded"
  .setRequestHeader "Accept", "application/json"
  .Send (strPostData)
   While .ReadyState <> 4
    DoEvents
   Wend
  strResult = .responseText
    Debug.Print strResult
End With

End Sub

无论哪种方式，返回的都是一个错误，即请求{“异常”：“moodle_异常”，“错误代码”：“noauthheader”，“消息”：“在发送到moodle的请求中未找到授权头”}。我猜这是一个格式问题，所以我尝试了各种各样的引号，我猜是标题类型声明（“授权”）和标记，但没有任何效果。我还发现了另一个人在CURL源下的这句话： “我的Apache 2版本删除了授权标头，导致noauthheader错误。添加此指令时，它起作用： SetEnvIf授权“（*）”HTTP_授权=$1” 但是，我不知道该错误源是否适用于我的案例，以及如何在VBA代码中实现该指令。任何帮助都将不胜感激！顺便说一句，这是locallib.php文件中相应的php代码，我认为curl请求应该指向：

     * Get the webservice authorization token from the request.
     * Throws error and notifies caller on failure.
     *
     * @param array $headers The extracted HTTP headers.
     * @return string $wstoken The extracted webservice authorization token.
     */
    private function get_wstoken($headers) {
        $wstoken = '';

        if (isset($headers['HTTP_AUTHORIZATION'])) {
            $wstoken = $headers['HTTP_AUTHORIZATION'];
        } else {
            // Raise an error if auth header not supplied.
            $ex = new \moodle_exception('noauthheader', 'webservice_restful', '');
            $this->send_error($ex, 401);
        }

        return $wstoken;
    }
