使用gotron-sdk发送gRPC请求

gotron-sdk截止至版本2.3.0，默认方式创建gRPC client暂不支持gRPC solidity节点连接。

在节点页面下载证书，将压缩包内的ca.crt证书放在项目内的目录。

在sdk中配置gRPC endpoint，示例代码如下：

import (
    "fmt"
    "google.golang.org/gRPC"
    "google.golang.org/gRPC/credentials"
    "github.com/fbsobreira/gotron-sdk/pkg/client"
)
func main() {
    gRPCWalletEndpoint := "your-gRPC-endpoint"
    credential := "your-credential"
    caPath := "your-ca.crt-file-path"
    creds, err := credentials.NewClientTLSFromFile(caPath, "")
    if err != nil {
        fmt.Printf("failed to load credentials: %v\n", err)
    }
    gRPCWalletClient := client.NewgRPCClient(gRPCWalletEndpoint)
    gRPCWalletClient.SetAPIKey(credential)
    gRPCWalletClient.Start(gRPC.WithTransportCredentials(creds))
    resp, err := gRPCWalletClient.GetNowBlock()
    if err != nil {
        fmt.Printf("failed to get now block: %v\n", err)
    }
    fmt.Println("wallet resp: ", resp)
}
