Ethercalc的單元格取值

本地架設Ethercalc後，訪問http://localhost:8000進入ethercalc首頁，創建新的工作簿，在A1單元格輸入數據1，A2單元格輸入數據2，A3輸入公式（=A1+A2），頁面顯示如下：

取單元格數據代碼如下：

import javax.ws.rs.client.Client;  
import javax.ws.rs.client.ClientBuilder;  
import javax.ws.rs.core.Response;  
import javax.ws.rs.core.MediaType;  
  
public class getValue {  
    public static void main(String args[]) {  
  
        Client client = ClientBuilder.newClient();  
        Response response = client  
                .target("http://localhost:8000/_/aaa/cells/A1")  
                .request(MediaType.TEXT_PLAIN_TYPE).get();  
  
        System.out.println("status: " + response.getStatus());  
        System.out.println("headers: " + response.getHeaders());  
        System.out.println("body:" + response.readEntity(String.class));  
    }  
} 

控制檯顯示：

A1單元格：
