问题描述
我正在尝试连接到事务节点，我在"truffle-config.js"中定义了连接字符串。如示例中所述（https://docs.microsoft.com/en-us/azure/blockchain/service/send-transaction).
$
````
var alpha =" https://alpha-test.blockchain.azure.com:3200 / ***********" ;;
var myAccount =" 0x1B21e60D66a0598F95096c214Fe84c960f80fF89" ;;
var myPassword =" *******" ;;
alpha：{
    provider：new Web3.providers.HttpProvider（alpha），
    network_id：" *"，
   燃气：0，
    gasPrice：0
 每当我执行truffle console命令连接到alpha节点时，我都会返回以下错误：
$
``
```
`
$
$ truffle console --network alpha
无法连接到您的以太坊客户端。
请检查您的以太坊客户：
  - 正在运行
  - 正在接受RPC连接（即，" - rpc"选项用于geth）
  - 可通过网络访问
  - 已在您的Truffle配置文件（truffle-config.js）中正确配置
```
而我能够连接到defaultnode和beta节点。我已经尝试使用浏览器访问rpc端点，它们似乎有效。但我无法通过松露这样做。请帮帮我。
I am trying to connect to transaction nodes, I've defined the connection strings in "truffle-config.js" as described in the example (https://docs.microsoft.com/en-us/azure/blockchain/service/send-transaction).
```
var alpha = "https://alpha-test.blockchain.azure.com:3200/***********";
var myAccount = "0x1B21e60D66a0598F95096c214Fe84c960f80fF89";
var myPassword = "*******";
alpha: {
provider: new Web3.providers.HttpProvider(alpha),
network_id: "*",
gas: 0,
gasPrice: 0
}
```
whenever I execute the truffle console command to connect to alpha node, I am returned the following error:
```
$ truffle console --network alpha
Could not connect to your Ethereum client.
Please check that your Ethereum client:
- is running
- is accepting RPC connections (i.e., "--rpc" option is used in geth)
- is accessible over the network
- is properly configured in your Truffle configuration file (truffle-config.js)
```
whereas I am able to connect to both the defaultnode and beta node. I've tried hitting the rpc endpoints using browser and they seem to work. But I am unable to do so via truffle. Please help me out.
