量化交易第一步，利用java获取交易实时数据

1.建立依赖

cn.hutool

hutool-all

5.5.9

2.输入代码

package projick;

import cn.hutool.http.HttpResponse;

import cn.hutool.http.HttpUtil;

public class opo {

public String splicingElement(String[] elements, int size,String comma) {

String ret = "";

String data_last = "";

for (int i = 0; i < size; i++) {

if(i<=size-2) {

ret += elements[i] + comma;

}

else {

data_last = elements[i];

}

}

return ret + data_last;

}

public static void main(String[] args) {

String[] list_1 = {"sh600104","sh600103","sh600104","sz000156","sh600587","sh113016", "sh113525", "sh111003", "sz123143"};

HttpResponse resp = HttpUtil.createGet("http://qt.gtimg.cn/q=" + new opo().splicingElement(list_1,9,",")).execute();

System.out.println(resp.body());

}

}
