go - Fabric SDK 无法初始化 cryptosuite 配置

Question

我在 IBM Cloud Blockchain Platform 2.0 上运行一个业务网络。我从平台控制台上的实例化智能合约部分下载了一个连接配置文件，并尝试使用 Fabric SDK for Go 进行连接，但我遇到了错误。

这是我当前的相关代码，在main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:我得到一个错误

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，请看下面。
