这个方法如何调用
type Client interface {
/GetProductBasicInfo 按symbol和product_code返回产品, isActive字段不生效, 不会过滤对应状态
若不传入channel, 则返回对应基金isActive为0, 渠道相关信息为空
若传入channel, 则isActive和渠道信息根据当前channel返回/
GetProductBasicInfo(ctx context.Context, params mapping.ProductBasicInfoParams) (mapping.ProductBasicInfo, error)
}
你可以通过实现该 Client 接口,然后在需要调用 GetProductBasicInfo 方法的地方使用这个实现。以下是一个示例代码:
首先,定义 mapping.ProductBasicInfoParams 和 mapping.ProductBasicInfo 的结构体:
1 2 3 4 5 6 7 8 9 10 11 12 13 14
| package mapping
type ProductBasicInfoParams struct { Symbol string ProductCode string Channel *string }
type ProductBasicInfo struct { ProductCode string Symbol string IsActive bool }
|
然后,实现 Client 接口:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31
| package main
import ( "context" "fmt" "mapping" )
type MyClient struct{}
func (c *MyClient) GetProductBasicInfo(ctx context.Context, params mapping.ProductBasicInfoParams) (mapping.ProductBasicInfo, error) { if params.Symbol == "" || params.ProductCode == "" { return mapping.ProductBasicInfo{}, fmt.Errorf("symbol and product_code are required") }
info := mapping.ProductBasicInfo{ ProductCode: params.ProductCode, Symbol: params.Symbol, IsActive: true, }
if params.Channel != nil { info.IsActive = *params.Channel == "active" }
return info, nil }
|
接下来,调用 GetProductBasicInfo 方法:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25
| package main
import ( "context" "fmt" "mapping" )
func main() { client := &MyClient{} ctx := context.Background() params := mapping.ProductBasicInfoParams{ Symbol: "AAPL", ProductCode: "12345", Channel: nil, }
info, err := client.GetProductBasicInfo(ctx, params) if err != nil { fmt.Println("Error:", err) return }
fmt.Printf("Product Info: %+v\n", info) }
|
以上示例展示了如何实现并调用 GetProductBasicInfo 方法。你可以根据实际需求修改实现的细节。
