一、什么是白银价格查询接口？

它聚焦于上海黄金交易所、上海期货交易所等权威市场，精准提供白银价格行情数据，助力用户实时把握市场脉搏，做出明智的投资决策。

二、应用场景

分析软件：金融类平台可以集成本接口，为用户提供实时的白银市场价值，帮助用户做出买卖决策。
贵金属商户：珠宝商和其他贩售白银产品的零售商可以使用API来设定和更新其产品的价格，确保其与国际白银市场价格保持一致，确保竞争力。
电商平台：在商品详情页嵌入白银实时价格，吸引投资者关注；或通过历史价格曲线分析，增强用户粘性。

三、如何用Java实现白银价格查询接口的调用？

下面我们以阿里云的接口为例，通过Java实现该接口的调用

接口地址：https://market.aliyun.com/apimarket/detail/cmapi00065850
	public static void main(String[] args) {
	    String host = "https://tssilver.market.alicloudapi.com";
	    String path = "/silver/london";
	    String method = "GET";
	    String appcode = "你自己的AppCode";
	    Map<String, String> headers = new HashMap<String, String>();
	    //最后在header中的格式(中间是英文空格)为Authorization:APPCODE 83359fd73fe94948385f570e3c139105
	    headers.put("Authorization", "APPCODE " + appcode);
	    Map<String, String> querys = new HashMap<String, String>();


	    try {
	    	/**
	    	* 重要提示如下:
	    	* HttpUtils请从
	    	* https://github.com/aliyun/api-gateway-demo-sign-java/blob/master/src/main/java/com/aliyun/api/gateway/demo/util/HttpUtils.java
	    	* 下载
	    	*
	    	* 相应的依赖请参照
	    	* https://github.com/aliyun/api-gateway-demo-sign-java/blob/master/pom.xml
	    	*/
	    	HttpResponse response = HttpUtils.doGet(host, path, method, headers, querys);
	    	System.out.println(response.toString());
	    	//获取response的body
	    	//System.out.println(EntityUtils.toString(response.getEntity()));
	    } catch (Exception e) {
	    	e.printStackTrace();
	    }
	}

正确的返回代码示例：
