Java编程实现NBA赛事接口调用实例代码

2017-11-20 16:07 816 查看

第一步：找别人提供的接口，比如在这里我选择的是聚合数据提供的接口

第二步：要申请相应的AppKey方可使用，此参数会作为接口的参数调用。

第三步：调用别人提供的接口方法

代码如下：

package juheapi.nba;
/**

import net.sf.json.JSONObject;
import java.io.*;
import java.net.HttpURLConnection;
import java.net.URL;
import java.net.URLEncoder;
import java.util.HashMap;
import java.util.Map;

params.put("key",APPKEY);
//应用APPKEY(应用详细页查询)
params.put("dtype","");
//返回数据的格式,xml或json，默认json
try {
result =net(url, params, "GET");
JSONObject object = JSONObject.fromObject(result);
if(object.getint("error_code")==0){
System.out.println(object.get("result"));

System.out.println(object.get("error_code")+":"+object.get("reason"));
}

//2.球队赛程赛事查询

在使用上述代码时可能会出现异常，一般都是由于jar包不全导致的。

问题一：抛出 NestableRuntimeException
