我已经编写了Google云功能（HTTP触发器）。它在google云界面中成功测试。现在，我需要从Unity Game（C＃.Net核心）中调用它。
首先，我尝试从浏览器运行它。我带了显示在Google云功能界面中的URL。这是行不通的。我没有得到stackdriver日志（它甚至没有命中URL？）。 是因为它需要oauth 2.0令牌吗？
我正在创建Http请求，嵌入JSON
request.ContentType = "application/json";
request.Method = "POST";
request.Headers["Authorization"] = "Bearer " + token;
//token obtained from oauth 2.0 JWT call
byte[] JsonContentBytes = Encoding.UTF8.GetBytes(strjsonReqContent);
// my Json object. requestJSON.ToString());
request.ContentLength = JsonContentBytes.Length;
在这里，我也尝试使用Oauth 2.0令牌。 （它适用于存储API。我的云功能服务帐户具有项目编辑者访问权限）
我从云项目外部看到了一篇有关使用云功能的文章。它没有解决我的问题。
请让我知道从云项目外部使用云功能的所有条件。
EDIT1：
谢谢你的建议。这是Curl执行的日志。我不习惯进行网络调试。请提出我应该进一步检查的内容。我可以确定这是“错误请求”。该URL是我从云功能控制台中选择的URL。
>curl -v -X POST https://us-central1- myproject.cloudfunctions.net/myfunctiontest -H "Content-Type:application/json" -d '{"username":"myemail@mydomain.com","password":"password1"}'
Note: Unnecessary use of -X or --request, POST is already inferred.

“错误请求”可能不是由于URL引起的，因为我来自云功能UI。请提出我应该如何进行。谢谢。
