将自定义标头添加到TIdHttp请求中，标头值带有逗号

我正在使用Delphi XE2和Indy 10.5.8.0。我有一个TIdHttp实例，我需要向请求添加一个自定义标头。标头值中包含逗号，因此会自动将其解析为多个标头。我不希望它那样做。我需要我的自定义标头的标头值仍然是一个字符串，而不是基于逗号分隔符。

I'm using Delphi XE2 and Indy 10.5.8.0. I have an instance of TIdHttp and I need to add a custom header to the request. The header value has commas in it so it's getting parsed automatically into multiple headers. I don't want it to do that. I need the header value for my custom header to still be one string and not split based on a comma delimiter.

我尝试设置 IdHttp1。 Request.CustomHeaders.Delimiter：=';'没有成功。有没有办法确保标头不会被拆分？

I have tried setting IdHttp1.Request.CustomHeaders.Delimiter := ';' with no success. Is there a way to make sure the header doesn't get split up?

procedure SendRequest;
const HeaderStr = 'URL-Encoded-API-Key VQ0_RV,ntmcOg/G3oA==,2012-06-13 16:25:19';
begin
  IdHttp1.Request.CustomHeaders.AddValue('Authorization', HeaderStr);
  IdHttp1.Get(URL);
end;
