Question

我正在Ubuntu服务器上运行Hyperledger fabric ver 1的Balance transfer example。在Node.js上暴露端口4000并尝试使用POSTMAN工具测试API。对于每个请求（POST或GET），我都收到同样的错误：

        </pre>
    </body>
</html>

我的猜测是，需要配置 jwt-express 库。有什么建议吗？

问题解决了！我没有传递用户在网络中注册时生成的授权标头 JSON Web Token（JWT）。

在通过Hyperledger结构v1上的Postman连接node.js表达API时出现UnauthorizedError
