java - 如何使用 Cloudinary API 列出 Cloudinary 中的所有 Public_Id？

Question

我已尽力使这段代码正常工作，但是，唉!肯定有什么问题。我试图列出 Cloudinary 中的所有 public_ids 。但它总是打印 null。下面是代码 -

import java.util.HashMap;
import java.util.Map;

import com.cloudinary.Api;
import com.cloudinary.Cloudinary;
import com.cloudinary.utils.ObjectUtils;

public class AllResources {

    @SuppressWarnings("unchecked")
    public static void main(String[] Args) {

        Map<String, String> config = new HashMap<>();
        config.put("cloud_name", "*******");
        config.put("api_key", "**************");
        config.put("api_secret", "***************************");
        Cloudinary c = new Cloudinary(config);
        Api api = c.api();

        try {           
            Map<String, Object> result = api.resources(ObjectUtils.asMap());
            System.out.println(result.get("public_id"));
        } catch (Exception e) {
            e.printStackTrace();
        }
    }

}

您可以执行以下操作:

String nextCursor = null;
do {
 result = api.resources(ObjectUtils.asMap("max_results", 500, "next_cursor", nextCursor));
 nextCursor = result.get("next_cursor");

 for (Map.Entry<String, Object> data : result.entrySet()) { 
   String key = data.getKey().toString(); 
   Object value = data.getValue(); 
   System.out.println(key + value); 
 }
} while (nextCursor != null);
