ArangoDB-NET Error: System.Net.WebException: 'No such host is known No such host is known'

Question

我正在做一个需要 Graph DB 的项目。我正在使用 C# .Net Core 开发项目。我不得不选择 ArangoDB 作为这个项目的 Graph DB。不幸的是，.Net 没有官方驱动程序。这就是我选择社区驱动程序的原因。即ArangoDB-NET.

https://www.nuget.org/packages/ArangoDB-NET/

https://github.com/yojimbo87/ArangoDB-NET

驱动程序在 我本地安装的 ArangoDB 数据库中工作正常。当我尝试在 ArangoDB Cloud (ArangoDB Oasis).

中部署数据库时，驱动程序返回错误

Error: System.Net.WebException: 'No such host is known No such host is known'

请检查以下有关数据库连接的信息：

连接字符串设置：

  "DatabaseSettings": {
    "ConnectionName": "CloudDBConnection",
    "Host": "https://xxxxxxxx.arangodb.cloud",
    "Port": 8529,
    "UserName": "root",
    "Password": "xxxxxxxx",
    "DatabaseName": "KKBDTestDB"
  }

数据库连接：

private readonly ADatabase db;
public DatabseService(IDatabaseSettings settings)
{
    ASettings.AddConnection(settings.ConnectionName, settings.Host, settings.Port, false, settings.DatabaseName, settings.UserName, settings.Password, true);
    db = new ADatabase(settings.ConnectionName);
}

Answer 1

1) 从您的主机名中删除 https，然后尝试。

连接字符串应该是：

"DatabaseSettings": {
    "ConnectionName": "CloudDBConnection",
    "Host": "xxxxxxxx.arangodb.cloud",
    "Port": 8529,
    "UserName": "root",
    "Password": "xxxxxxxx",
    "DatabaseName": "KKBDTestDB"
  }

2) 从 arongodb 云下载 public 密钥 windows 并按照以下步骤：

将证书 (PEM) 转换为 ca-9676da18.crt
以运行管理员身份打开 Powershell
certutil -addstore root ca-9676da18.crt
