对接微信支付V3涉及的URI - URL处理

import okhttp3.HttpUrl;
import java.net.URI;
import java.net.URISyntaxException;

public class Demo {
    public static void main(String[] args) {
        try {
            //方式一：
            URI uri = new URI("https://api.mch.weixin.qq.com/v3/merchant/media/upload?a=1&b=0");
            String url = uri.getPath();
            String queryParams2 = uri.getQuery();
            System.out.println("url: "+ url);
            System.out.println("urqueryParams2l: "+ queryParams2);
            //方式二：
            HttpUrl httpurl = HttpUrl.parse("https://api.mch.weixin.qq.com/v3/merchant/media/upload?a=1&b=0");
            String canonicalUrl = httpurl.encodedPath();
            System.out.println("canonicalUrl: "+ canonicalUrl);
            String queryParams = httpurl.encodedQuery();
            System.out.println("queryParams: "+ queryParams);
            if (queryParams != null) {
                canonicalUrl += "?" + queryParams;
            }
            System.out.println("canonicalUrl: "+ canonicalUrl);
        } catch (URISyntaxException e) {
            e.printStackTrace();
        }
    }
}

输出结果：

url: /v3/merchant/media/upload
urqueryParams2l: a=1&b=0
canonicalUrl: /v3/merchant/media/upload
queryParams: a=1&b=0
canonicalUrl: /v3/merchant/media/upload?a=1&b=0
