【驱动量化交易28】教你如何通过股票数据api接口获取股票指数历史分时KDJ数据之Python、Java等多种主流语言实例代码演示通过股票数据接口获取数据

如今，量化分析在股市领域风靡一时，其核心要素在于数据，获取股票数据，是踏上量化分析之路的第一步。你可以选择亲手编写爬虫来抓取，但更便捷的方式，莫过于利用专业的股票数据API接口。自编爬虫虽零成本，却伴随着时间与精力的巨大消耗，且常因目标页面变动而失效。大家可以依据自己的实际情况来决定数据获取方式。

接下来，我将分享200多个实测可用且免费的专业股票数据接口，并通过Python、JavaScript（Node.js）、Java、C#、Ruby等五种主流语言，逐一演示如何高效获取各类股票数据，希望能够对大家有所帮助。

先把数据接口的地址给大家，大家可以直接点击地址或复制到地址栏打开，马上就可以验证接口的有效性

沪深指数历史分时KDJ数据API接口：http://api.mairuiapi.com/hsindex/history/kdj/000001.SH/d/n/LICENCE-66D8-9F96-0C7F0FBCD073

【特别提示】：下方验证接口的licence证书（LICENCE-66D8-9F96-0C7F0FBCD073）为官方提供的验证证书，该证书只能验证股票代码000001的股票，因此，下方的接口连接中，即使换掉代码实际返回的也是000001的数据，在实际应用中，需要自己去申请一个免费证书更换掉就可以随意请求数据了，免费证书的申请连接（点击即可马上得到证书）：https://www.mairuiapi.com/getlicence

1、python

import requests

url = "http://api.mairuiapi.com/hsindex/history/kdj/000001.SH/d/n/LICENCE-66D8-9F96-0C7F0FBCD073"
response = requests.get(url)
data = response.json()
print(data)

2、JavaScript (Node.js)

const axios = require('axios');

const url = "http://api.mairuiapi.com/hsindex/history/kdj/000001.SH/d/n/LICENCE-66D8-9F96-0C7F0FBCD073";
axios.get(url)
.then(response => {
console.log(response.data);
})
.catch(error => {
console.log(error);
});

3、Java

import java.net.URI;
import java.net.http.HttpClient;
import java.net.http.HttpRequest;
import java.net.http.HttpResponse;
import java.io.IOException;

public class Main {
public static void main(String[] args) {
HttpClient client = HttpClient.newHttpClient();
HttpRequest request = HttpRequest.newBuilder()
.uri(URI.create("http://api.mairuiapi.com/hsindex/history/kdj/000001.SH/d/n/LICENCE-66D8-9F96-0C7F0FBCD073"))
.build();

try {
HttpResponse response = client.send(request, HttpResponse.BodyHandlers.ofString());
System.out.println(response.body());
} catch (IOException | InterruptedException e) {
e.printStackTrace();
}
}
}

4、C#

using System;
using System.Net.Http;
using System.Threading.Tasks;

class Program
{
static async Task Main()
{
using (HttpClient client = new HttpClient())
{
string url = "http://api.mairuiapi.com/hsindex/history/kdj/000001.SH/d/n/LICENCE-66D8-9F96-0C7F0FBCD073";
HttpResponseMessage response = await client.GetAsync(url);
string responseBody = await response.Content.ReadAsStringAsync();
Console.WriteLine(responseBody);
}
}
}

5、Ruby

require 'net/http'
require 'json'

url = URI("http://api.mairuiapi.com/hsindex/history/kdj/000001.SH/d/n/LICENCE-66D8-9F96-0C7F0FBCD073")

http = Net::HTTP.new(url.host, url.port)
request = Net::HTTP::Get.new(url)
response = http.request(request)
data = JSON.parse(response.read_body)
puts data

返回数据示例：

{"t":"2024-12-17 10:30","k":9.55,"d":9.55,"j":9.55},{"t":"2024-12-17 11:30","k":7.12,"d":8.74,"j":3.88},{"t":"2024-12-17 14:00","k":12.45,"d":9.98,"j":17.39},{"t":"2024-12-17 15:00","k":10.15,"d":10.04,"j":10.37},{"t":"2024-12-18 10:30","k":24.72,"d":14.93,"j":44.3},{"t":"2024-12-18 11:30","k":38.38,"d":22.74,"j":69.66}

返回的数据字段说明：
