访问 Hyperldger 资源管理器时出错 "Cannot GET /"

Question

我已经使用 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错误 Explorer 同步过程正在为网络持续进行能够查看DB中更新的数据 http://localhost:8080/api-docs/ (Explorer Swagger) 工作正常。但是，在访问 http://localhost:8080/ 时，我得到

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

如果您使用 docker compose 启动资源管理器，即在 repo 的根目录中，然后检查您的 8090 端口，因为 docker 将容器的 8080 端口映射到您机器的 8090 端口。

见github:hyperledger/blockain-explorer/docker-compose.yaml

Answer 2

所以，我找到了问题的答案—— 奇怪的是，问题是它到处都显示它在 localhost:8080 上提供服务，但经过大量研究发现节点 js 无法提供 hyperledger explorer 在端口 8080 上的静态页面。因此，需要使用 "serve" 来构建和提供该页面。我在 2 天前做过，它从端口 5000 开始，它有自己的 IP 地址，但是我在网络浏览器上遇到错误，因为违反了 "control security policy".

解法：

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

现在它会向您显示如下输出：


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

如果你打开 : http://localhost:5000 它不会显示任何内容，在检查 window 的网络日志中会显示 - "control security policy violation".

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 资源管理器服务器：

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

您将看到选择了第一个网络的登录页面。

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.

你在！
