无法连接到本地 azure cosmosdb 模拟器

Question

我在我的 Win10 电脑上安装了Azure CosmosDB Emulator，并且我可以看到启动页面：

但是当我尝试通过 Robo3T 或命令行连接到数据库时，它不起作用。我使用以下命令：

mongo mongodb://localhost:foofoojf5%2FR%2Bob0N8A7Cgv30VRDJIWEHLM%2B4QDU5DE2nQ9nDuVTqobD4b8mGGyPMbIZnqyMsEcaGQy67XIw%2FJw%3D%3D@localhost:10255/admin?ssl=true

我遇到了以下问题：

2019-07-18T14:33:27.265+0200 W NETWORK [thread1] 5000ms 毫秒后无法连接到 127.0.0.1:10255，放弃。 2019-07-18T14:33:27.266+0200 E QUERY [thread1] 错误：无法连接到服务器 localhost:10255，连接尝试失败： 连接@src/mongo/shell/mongo.js:237:13 @(连接):1:6 异常：连接失败

它在本地，所以我认为没有端口问题。是否可能与本地证书或我的公司防火墙有关？

在我的例子中，要与用于 MongoDb 的 Azure CosmosDb API 交互，我们需要在 %localappdata%\CosmosDbEmulator 下创建一个专用的新文件夹并启用 MongoDb 端点 v3.6（请参阅下面 第 1 步中的 PowerShell 命令）。

注意： 出于任何原因，如果 CosmosDb 模拟器重置为默认文件夹路径 %localappdata%\CosmosDbEmulator（或）无法在 Robo 3T 中连接 然后总是在 Step 1 中再次执行下面的 PowerShell 脚本。

注意： 从 Robo 3T v1.4 开始，我们没有连接 SSL 标签 设置对话框。相反，我们有一个选项卡 TLS。

1. Download and install Azure CosmosDb Emulator from https://docs.microsoft.com/en-us/azure/cosmos-db/local-emulator?tabs=powershell%2Cssl-netstd21
2. Download and install Robo 3T (1.4.2 or latest) from https://robomongo.org/download
3. To show Azure CosmosDb emulator related database(s) in Robo 3T client app

Step 1
- Launch Azure CosmosDb Emulator 
  (Optional: Just to check CosmosDbEmulator is started successfully)
- Open Powershell as administrator and execute below commands

  # PowerShell Script
  # Change directory to default location where CosmosDb emulator is installed.
  cd\
  cd '.\Program Files\Azure Cosmos DB Emulator\'
             
  # [Optional] If any cosmosDb emulator instance is running then shutdown
  .\Microsoft.Azure.Cosmos.Emulator.exe /shutdown
        
  # To interact Azure CosmosDb API for MongoDb, create a new folder "<MongoDb>" under 
  # %localappdata%\CosmosDbEmulator and enable MongoDb endpoint v3.6
  .\Microsoft.Azure.Cosmos.Emulator.exe /DataPath="$env:localappdata\CosmosDBEmulator\MongoDb" /EnableMongoDbEndpoint=3.6

Step 2      
- Now CosmosDb emulator will be successfully started,
  and launches the URL https://localhost:8081/_explorer/index.html in the browser
- Note down MongoDb connection string details from browser which will be required 
  while creating new Robo 3T connection. The default MongoDb connection string format is 
  mongodb://username:password@host:port/[database]?ssl=true
    - Username: localhost
    - Password (Primary Key): C2y6yDjf5/R+ob0N8A7Cgv30VRDJIWEHLM+4QDU5DE2nQ9nDuVTqobD4b8mGGyPMbIZnqyMsEcaGQy67XIw/Jw==
    - Port: 10255
    - Database: admin
    
Step 3
- Launch Robo 3T
- Click on Create new connection 
- In "Connection" tab
    - Provide Name of the connection as "<CosmosDbEmulator>"
    - Add port number as 10255
        
- In "Authentication" tab provide details noted down in previous Step 2
    - Check "Perform authentication"
    - Add Database as "admin"
    - Add Username as "https://localhost:8081"
    - Add Password as "C2y6yDjf5/R+ob0N8A7Cgv30VRDJIWEHLM+4QDU5DE2nQ9nDuVTqobD4b8mGGyPMbIZnqyMsEcaGQy67XIw/Jw=="
        
- In "TLS" tab provide
    - Check "Use TLS protocol"
    - From Authentication Method dropdown select "Self-signed Certificate"
        
- Click on "Test" button. 
    - It should successfully connects to localhost:10255 via TLS tunnel
    - It should successfully authorise to database "admin"
    
- Click on "Save" button    
- Click on "Connect" button. 
    - It will show the admin database and its related collections.

我用ROBO3T工具连接了mongo模拟器，请看我的配置。

首先，从这个link获取模拟器连接字符串。

mongodb://localhost:C2y6yDjf5/R+ob0N8A7Cgv30VRDJIWEHLM+4QDU5DE2nQ9nDuVTqobD4b8mGGyPMbIZnqyMsEcaGQy67XIw/Jw==@localhost:10255/admin?ssl=true

然后创建连接配置：
