调用 "github.com/jackc/pgx".Connect 时参数过多
Too many arguments in call to "github.com/jackc/pgx".Connect
我正在尝试使用 pgx 打开与 postgres 数据库的连接,但出现以下错误:
./dbservice.go:12:26: too many arguments in call to "github.com/jackc/pgx".Connect
have (context.Context, string)
want ("github.com/jackc/pgx".ConnConfig)
./dbservice.go:13:18: too many arguments in call to conn.Close
have (context.Context)
want ()
./dbservice.go:21:44: cannot use context.Background() (type context.Context) as type string in argument to conn.Query
我不确定错误要求我在这里做什么。 pgx.Connect
当我从主文件调用它时有效,但在这里它不起作用。这是代码:
func initNodes(nodes *[]Node, searchNodes *[]SearchNode, storageNodes *[]StorageNode) error {
conn, err := pgx.Connect(context.Background(), DATABATE_URL)
defer conn.Close(context.Background())
if err != nil {
fmt.Printf("Connection failed: %v\n", err)
os.Exit(-1)
}
...
func main() {
a:= Arbiter{}
a.init()
}
有什么想法吗?
