在C#/Mono中，无法与google云存储通信

我现在正在开发一个C#应用程序，通过Mono在Linux实例上运行。在完成图像处理后，它需要将图像存储在谷歌云存储中

我有身份验证凭据设置，.NET客户端库能够设置

StorageService

对象（即找到JSON文件并验证所有内容）。当我试图上传时，什么也没发生。因此，在我的

SetupConnection（）

函数中，我试图查询我在项目中拥有的单个bucket。我得到了这个错误：

我以前能够让C#与地面军事系统对话，但那是我在Windows环境下使用Microsoft的.NET虚拟机的时候。我之前做了一些研究，Mono处理CAs的方式与Microsoft的VM相比可能存在一些问题。

您的问题通常来自未更新的根证书

按照说明更新根证书

如果这没有帮助，那么可以将委托设置为

ServicePointManager.ServerCertificateValidationCallback

并接受所有证书。如果这样做有效，那么您就知道问题出在证书验证上，您可以尝试其他解决方案。（我不建议使用回调来接受生产中的所有证书，只需使用它来调试您的问题即可）。

我修复了这个问题

我使用的是Ubuntu附带的默认Mono版本，但它已经过时了。我在这里切换到使用官方Mono存储库：

然后还安装了

ca证书mono

软件包。（更多详情请参见此处：）

感谢Lex Li的帮助。

哪种版本的Mono？在终端运行

mono--version

。mono-JIT编译器版本3.2.8太旧了。首先通过研究他的站点升级，这是Ubuntu PPA中的默认站点。不过我会尝试一下，然后告诉你会发生什么。你遇到了Ubuntu支持的限制（他们希望你停留在旧版本上），而在.NET/Mono/GCS上正好相反，它通常要求你使用最新版本。你必须决定走哪条路。

ServicePointManager.ServerCertificateValidationCallback
