java - 无法导入 org.json.simple.JSONObject 出现错误，提示 "org.jason cannot be resolved"

Question

我正在尝试编写一个程序，该程序读取 Web 服务并使用 JSONObject 对象对其进行表述。我正在使用 Eclipse

当我尝试导入库 org.json.simple.JSONObject 时；我收到一条错误消息“org.jason 无法解析”

代码 list

import java.net.URL;

import org.json.simple.JSONObject;

//错误信息“导入“org.json 无法解析”

import java.io.*;
import javax.net.ssl.HttpsURLConnection; // This is where I get the error message

public class cStart {

    cGraphData ReadData;

     public static void main (String[] args) {

               System.out.println("Welcome to the world of Java Programming.");
               String reply="";
               cGraphData ReadData= new cGraphData();
              try {
               String httpsURL = "https://bittrex.com/api/v1.1/public/getticker?market=BTC-LTC";
               URL myurl = new URL(httpsURL);
               HttpsURLConnection con = (HttpsURLConnection)myurl.openConnection();
               InputStream ins = con.getInputStream();
               InputStreamReader isr = new InputStreamReader(ins);
               BufferedReader in = new BufferedReader(isr);

               String inputLine;


               while ((inputLine = in.readLine()) != null)
               {
                   reply+=inputLine;
               }
              } catch (Exception e)
              {
                  System.out.println("Exception in getting data from server");
              }
              System.out.println(reply);
              JSONObject t;


}

}

只需将 gradle 或 maven 依赖项添加到您的项目中对于梯度:

compile group: 'org.json', name: 'json', version: '20180130'

对于行家

<dependency>
    <groupId>org.json</groupId>
    <artifactId>json</artifactId>
    <version>20180130</version>
</dependency>
