Golang dcrjson.UnmarshalCmd函数代码示例

// This example demonstrates how to unmarshal a JSON-RPC request and then
// unmarshal the concrete request into a concrete command.
func ExampleUnmarshalCmd() {
	// Ordinarily this would be read from the wire, but for this example,
	// it is hard coded here for clarity.

	var request dcrjson.Request

	// like this as the caller already knows what response to expect based
	// on the command it sent.  However, this is done here to demonstrate
	// why the unmarshal process is two steps.
	if request.ID == nil {

	// Display the fields in the concrete command.
	fmt.Println("Hash:", gbCmd.Hash)
	fmt.Println("Verbose:", *gbCmd.Verbose)
	fmt.Println("VerboseTx:", *gbCmd.VerboseTx)

	// Output:
	// Hash: 000000000019d6689c085ae165831e934ff763ae46a2a6c172b3f1b60a8ce26f
