node.js - 访问 Hyperldger 资源管理器时出错“无法获取 /”

Question

我已经用 Explorer（最新版本）配置了我们的 Fabric 网络（v1.4）。

node --version v8.16.0

数据库日志中没有错误没有应用程序级别错误资源管理器同步过程正在为网络持续进行能够查看数据库中的更新数据 http://localhost:8080/api-docs/（Explorer Swagger）工作正常。但是，在访问http://localhost:8080/时，我得到了

无法获取/错误。

Chrome 检查日志 -

Failed to load resource: the server responded with a status of http://localhost:8080/ 404 (Not Found)

Answer 1

所以，我找到了问题的答案——奇怪的是，问题在于它到处都显示它在 localhost:8080 上提供服务，但经过大量研究发现 node js 无法提供超级账本资源管理器在端口 8080 上的静态页面。所以，需要使用“服务”来构建和服务该页面。两天前我已经这样做了，它从端口 5000 和它自己的 IP 地址开始，但是由于违反“控制安全策略”而在 Web 浏览器上出现错误。

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

现在它将向您显示类似的输出：

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

如果您打开：http://localhost:5000它不会显示任何内容，并且在检查窗口的网络日志中会显示 - “控制安全策略违规”。

所以像这样使用端口 8080 ：

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

此外，您需要启动 hyperldger explorer 服务器：

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

您将看到选择了第一个网络的登录页面。

利用 ：

"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.

你在！
