推荐答案

因此，我找到了问题的答案-奇怪的是，该问题无处不在，它可以在localhost:8080上运行，但是经过大量研究发现，节点js无法为静态页面提供服务，而Hyperledger Explorer在8080端口上.因此，需要使用服务"来构建和服务该页面.我两天前就做了，它从端口5000开始，并且是它自己的IP地址，但是由于违反控制安全策略"，我在网络浏览器上收到错误消息.

So, I found the answer to the problem - Weirdly the problem was it shows everywhere that it serves on localhost:8080 but after a lot of research found out that node js cannot serve static pages which hyperledger explorer is on port 8080. So, needs to use "serve" to build and serve that page. I had did that 2 days back, it starts on port 5000 and it`s own IP address, but I was getting error on web browser for violation of "control security policy".

解决方案:

$ cd ~/Hyperledger/blockchain-explorer/client
$ npm install
$ npm test -- -u --coverage 
$ npm run build
$ npm install -g serve
$ serve -s build

现在它将显示类似以下内容的输出:

Now it will show you the output something like :

   ┌────────────────────────────────────────────────────┐
   │                                                    │
   │   Serving!                                         │
   │                                                    │
   │   - Local:            http://localhost:5000        │
   │   - On Your Network:  http://160.33.244.178:5000   │
   │                                                    │
   │   Copied local address to clipboard!               │
   │                                                    │
   └────────────────────────────────────────────────────┘

如果打开: http://localhost:5000 它不会显示任何内容，并且在网络上登录检查窗口将显示-违反控制安全策略".

If you open up : http://localhost:5000 it will not show anything and in the network logs on inspect window will show you - "control security policy violation".

因此使用端口8080代替:

so use port 8080 instead like this :

- Local:            http://localhost:8080        │
- On Your Network:  http://160.33.244.178:8080

此外，您还需要启动hyperldger Explorer服务器:

Also, you would need to start the hyperldger explorer server :

$ cd ~/<YourPath>/blockchain-explorer
$ ./start.sh

您将看到选择了第一个网络的登录页面.

You will see login page with first network selected.

使用:

"adminUser" is the the admin user of the network, in this case it's fabric CA or an identity user.
"adminPassword" is the password for the admin user.

您在！
