gotdx
golang实现的一个通达信数据协议库
1. 概要
2. 编写测试代码
第一次运行时, 连接池会探测服务器网络速度会慢一些, 网络测速后会缓存到本地。
2.1. 创建 tdx.go
package tdx
import (
"gitee.com/quant1x/tdx/proto"
"gitee.com/quant1x/tdx/quotes"
"strings"
)
var (
stdApi *quotes.StdApi = nil
)
func prepare() *quotes.StdApi {
if stdApi == nil {
std_api, err := quotes.NewStdApi()
if err != nil {
return nil
}
stdApi = std_api
}
return stdApi
}
func startsWith(str string, prefixs []string) bool {
if len(str) == 0 || len(prefixs) == 0 {
return false
}
for _, prefix := range prefixs {
if strings.HasPrefix(str, prefix) {
return true
}
}
return false
}
// 判断股票ID对应的证券市场匹配规则
//
// ['50', '51', '60', '90', '110'] 为 sh
// ['00', '12','13', '18', '15', '16', '18', '20', '30', '39', '115'] 为 sz
// ['5', '6', '9'] 开头的为 sh, 其余为 sz
func getStockMarket(symbol string) string {
//:param string: False 返回市场ID,否则市场缩写名称
//:param symbol: 股票ID, 若以 'sz', 'sh' 开头直接返回对应类型,否则使用内置规则判断
//:return 'sh' or 'sz'
market := "sh"
if startsWith(symbol, []string{"sh", "sz", "SH", "SZ"}) {
market = strings.ToLower(symbol[0:2])
} else if startsWith(symbol, []string{"50", "51", "60", "68", "90", "110", "113", "132", "204"}) {
market = "sh"
} else if startsWith(symbol, []string{"00", "12", "13", "18", "15", "16", "18", "20", "30", "39", "115", "1318"}) {
market = "sz"
} else if startsWith(symbol, []string{"5", "6", "9", "7"}) {
market = "sh"
} else if startsWith(symbol, []string{"4", "8"}) {
market = "bj"
}
return market
}
func getStockMarketId(symbol string) uint8 {
market := getStockMarket(symbol)
marketId := proto.MarketShangHai
if market == "sh" {
marketId = proto.MarketShangHai
} else if market == "sz" {
marketId = proto.MarketShenZhen
} else if market == "bj" {
marketId = proto.MarketBeiJing
}
//# logger.debug(f"market => {market}")
return uint8(marketId)
}
// GetKLine 获取日K线
func GetKLine(code string, start uint16, count uint16) *quotes.SecurityBarsReply {
api := prepare()
marketId := getStockMarketId(code)
data, _ := api.GetKLine(marketId, code, proto.KLINE_TYPE_RI_K, start, count)
return data
}
2.2. 测试 tdx_test.go
package tdx
import (
"fmt"
"testing"
)
func TestGetKLine(t *testing.T) {
data := GetKLine("000002", 0, 1)
fmt.Println(data)
}
