Using gotron-sdk to Send gRPC Requests

gotron-sdk of the version 2.3.0 and earlier is supported. The gRPC client created in default mode does not support the connection to the gRPC solidity node.

Download the certificate on the node details page and place the ca.crt certificate in the package under the project directory.

Configure the gRPC endpoint in the SDK. The sample code is as follows:

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)
}
