import (
"fmt"
"strings"
cb "github.com/hyperledger/fabric/protos/common"
"github.com/golang/protobuf/proto"
)
像例子裡面的cb就是後面要引用的包的别名(防止沖突)
格式:别名+空格+引用的包名(包名加雙引号)
import (
"fmt"
"strings"
_ "github.com/hyperledger/fabric/protos/common"
"github.com/golang/protobuf/proto"
)
前面加下劃線,隻調用包裡面的init函數。無法調用包中别的函數。
import (
. "fmt"
"strings"
cb "github.com/hyperledger/fabric/protos/common"
"github.com/golang/protobuf/proto"
)
fmt前面加點,調用函數時可以省略包的名字。即:fmt.println()可以寫成println()
