Question

我正在IBM Cloud Blockchain Platform 2.0上运行业务网络。我从平台控制台的实例化智能合约部分下载了连接配置文件，并尝试使用Fabric SDK for Go进行连接，但遇到错误。

这是我当前的相关代码，位于主菜单下

configOpts := fabricConfig.FromFile("./profiles/flex.json")
fabSDK, err := fabsdk.New(configOpts)
if err != nil {
    entry.WithError(err).Fatal("Error setting up Fabric SDK")
}
defer fabSDK.Close()

预期：连接到业务网络实例

实际：我遇到了错误

FATA[0000] Error setting up Fabric SDK env=DEV 
error="failed to initialize configuration: unable to initialize cryptosuite using crypto suite config: 
failed to initialize crypto suite: Unsupported BCCSP Provider: "

Answer 1

我将“ cryptoconfig”路径添加到客户端。

BCCSP是可选的，您可以删除。

我添加了示例配置，请参见下文。

在Github go-SDK config.yaml上更详细的配置
