Sample Integration Code (Go)
Here’s a simple example of how to fetch k-line data using Go:
package main
import (
"io/ioutil"
"log"
"net/http"
)
func httpExample() {
url := "http://quote.aatest.online/quote-stock-b-api/kline?token=e945d7d9-9e6e-4721-922a-7251a9d311d0-1678159756806&query=%7B%22trace%22%20%3A%20%22go_http_test1%22%2C%22data%22%20%3A%20%7B%22code%22%20%3A%20%225.HK%22%2C%22kline_type%22%20%3A%201%2C%22kline_timestamp_end%22%20%3A%200%2C%22query_kline_num%22%20%3A%202%2C%22adjust_type%22%3A%200%7D%7D"
log.Println("request：", url)
resp, err := http.Get(url)
if err != nil {
log.Println("req error：", err)
return
}
defer resp.Body.Close()
body, err := ioutil.ReadAll(resp.Body)
if err != nil {
log.Println("read response error：", err)
return
}
log.Println("response：", string(body))
}This lightweight integration demonstrates how easily developers can pull structured financial data into their applications—without requiring specialized infrastructure or legacy languages.
