Fabric-sdk-go开发指南

fabric-sdk-go相关的测试参考见fabric-sdk-go(master版本)的README.md文件，现把重要的部分摘抄如下：

  • E2E Test: Basic example that uses SDK to query and execute transaction
  • Ledger Query Test: Basic example that uses SDK to query a channel's underlying ledger
  • Multi Org Test: An example that has multiple organisations involved in transaction
  • Dynamic Endorser Selection: An example that uses dynamic endorser selection (based on chaincode policy)
  • E2E PKCS11 Test: E2E Test using a PKCS11 crypto suite and configuration
  • CLI: An example CLI for Fabric built with the Go SDK.
  • More examples needed!
