Requirements

Following are the software dependencies required to install and run hyperledger explorer
  • nodejs 6.9.x (Note that v7.x is not yet supported)
  • mysql 5.7 or greater
Hyperledger Explorer works with Hyperledger Fabric 1.0. Install the following software dependencies to manage fabric network.

Clone Repository

Clone this repository to get the latest using the following command.
  1. git clone https://github.com/hyperledger/blockchain-explorer.git
  2. cd blockchain-explorer

Database setup

Run the database setup scripts located under db/fabricexplorer.sql
mysql -u -p < db/fabricexplorer.sql

Fabric network setup

This repository comes with a sample network configuration to start with
  1. cd first-network
  2. ./bootstrap-1.0.2.sh - This is going to download the necessary binaries and hyperledger docker images.
  3. mkdir -p ./channel-artifacts
  4. ./byfn.sh -m generate -c mychannel
  5. ./byfn.sh -m up -c mychannel
Alternatively you can setup your own network using Build your network tutorial from Fabric. Once you setup the network, please modify the values in network-config.json accordingly.
This brings up a 2 org network with channel name mychannel .

Running blockchain-explorer

On another terminal,
  1. cd blockchain-explorer
  2. Modify config.json to update the values for
    • channels
    • mysql host, username, password details
    • tls
 "channelsList": ["mychannel"],
 "enableTls":true, 
 "mysql":{
      "host":"127.0.0.1",
      "database":"fabricexplorer",
      "username":"root",
      "passwd":"123456"
   }
  1. npm install
  2. ./start.sh
Launch the URL http://localhost:8080 on a browser.

SIMPLE REST-API

This also provides a simple rest-api to access the following
  • Block
  • Transaction
  • Peer Status
  • List of chaincodes deployed
//get block info
curl -X POST  http://localhost:8080/api/block/json -H 'cache-control: no-cache' -H 'content-type: application/json' -d '{
    "number":"${block number}"
}'

//get transcation JOSN
curl -X POST  http://localhost:8080/api/tx/json -H 'cache-control: no-cache' -H 'content-type: application/json' -d '{
    "number":"${ Tx hex }"
}'


//get peer status
curl -X POST  http://localhost:8080/api/status/get -H 'cache-control: no-cache' -H 'content-type: application/json' -d ''

//get chaincode list
curl -X POST  http://localhost:8080/chaincodelist -H 'cache-control: no-cache' -H 'content-type: application/json' -d ''
  • Query to fetch channels
http://localhost:8080/apis/channels?peer=peer1

returns:

{"channels":[{"channel_id":"mychannel1"},{"channel_id":"mychannel2"}]}
  • Query to get BlockCount on a channel
http://localhost:8080/apis/channels/:channelname/height

example:

http://localhost:8080/apis/channels/mychannel1/height

returns:

11
  • Query to fetch all Installed/instantiated chaincodes

example:

http://localhost:8080/apis/chaincodes?channel=mychannel1

returns:

[{"name":"mycc","version":"v1","path":"github.com/uniqueKeyValue"}]
  • Query for Channel Information
http://localhost:8080/apis/channels/:channelName?peer=peer1

example:

http://localhost:8080/apis/channels/mychannel1?peer=peer1

returns:

PHP, which stands for Hypertext Preprocessor, is a server-side scripting language designed for web development, but which is also used as a general-purpose programming language.
