根据Moments.insert与Google+ API的文档说明,需要使用以下范围进行身份验证
https://www.googleapis.com/auth/plus.login
我正在使用所有可能的PlusService范围进行身份验证,但我仍然收到以下错误
Google.Apis.Requests.RequestError未经授权[401]错误[ 消息[未经授权]位置[ - ]原因[未经授权] 域[全球]

if (ex.InnerException.Message.IndexOf("access_denied") != -1) {
Console.WriteLine("User declined access");
Console.ReadLine();
return;
} else {
Console.WriteLine("Unknown Authentication Error:" + ex.Message);
Console.ReadLine();
return;
}
}
// Now we create a Google service. All of our requests will be run though this.
service = new PlusService(new BaseClientService.Initializer() {
HttpClientInitializer = credential,
ApplicationName = "Google Plus Sample",
});

我已经测试了身份验证,它正在运行,我可以列出活动和其他内容。它唯一的插入时刻给了我这个错误。我也试过在PHP中这样做,我得到同样的错误。我错过了什么?
更新:我在moments.insert
的文档中找到了一些内容在对moment.insert进行身份验证时,您必须包含 data-requestvisibleactions参数指定哪些类型的App 您的申请将要写的活动。
我还没想出如何设置这个数据请求可见的行为。
答案 0 :(得分:0)
正如您所注意到的,您需要将request_visible_actions
参数添加到请求中。来自Google的大多数其他OAuth库都添加了一个快捷方式来执行此操作,但看起来.NET库还没有。例如,PHP库有setRequestVisibleActions()。
在内部,便捷方法GoogleWebAuthorizationBroker.AuthorizeAsync()
调用AuthorizationCodeFlow.CreateAuthorizationCodeRequest()
来生成调用中使用的URL。您可以继承AuthorizationCodeFlow
和AuthorizationCodeRequestUrl
(它返回)以添加有问题的参数,然后更直接地浏览流程。
您可以在https://github.com/gguuss/google-dotnet-demo/blob/master/AuthWithAppActivities/Program.cs
查看如何执行此操作的示例您还可以使用Google+ Sign-In button执行初始身份验证流程并将一次性代码传递给服务器,然后服务器可以继续将其转换为有效令牌。由于登录按钮具有data-requestvisibleactions
属性,因此将为您处理身份验证的这一部分。
