Indy 10 in Lazarus RingCentral API RingOut TIdHTTP

如何解决Indy 10 in Lazarus RingCentral API RingOut TIdHTTP

拉撒路1.8.4
Indy 10（2020年3月）
Windows Server 2016

我正在尝试为我在Lazarus中建立的联系人列表构建一个小的“拨号程序”模块。经过几个月的摸索，我终于能够将所有RingCentral API设置转换为Postman，然后转换为Indy HTTP设置，以完成令牌的获取。该部分工作可靠。但是，我无法执行RingOut API。我总是找不到404。 RingCentral在其文档中提供的其他编程语言中的示例无法很好地转换为Indy。

if htpCall.Connected then
  htpCall.Request.Connection := 'close';  // Close the socket after using it to obtain the token
htpCall.Request.Clear;

htpCall.Request.Accept := 'application/json';
htpCall.Request.ContentType := 'application/json';
htpCall.Request.Username := '<redacted>';   // Client ID
htpCall.Request.Password := '<redacted>';   //  Client Secret
htpCall.Request.CustomHeaders.Clear;
htpCall.Request.CustomHeaders.FoldLines := False;
htpCall.Request.BasicAuthentication := False;
htpCall.Request.CustomHeaders.AddValue('Authorization','Bearer ' + acc_tkn);

prms_lst.Add('from=<redacted>');
prms_lst.Add('to=<redacted>');
prms_lst.Add('callerId=<redacted>');
prms_lst.Add('country=Canada');
prms_lst.Add('playPrompt=true');

// Remove the text ".devtest" for the production version of your code,and replace the phone account with the real main phone number
htpCall.Post('https://platform.devtest.ringcentral.com/restapi/v1.0/account/<redacted>/extension/101/ring-out',prms_lst);

更新：

如果我将TIdHTTP保持打开状态，然后运行上面的代码，则会收到其他错误。
