一、工具类，直接粘贴调用即可
package cn.com.service.httpReq;
import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;
import java.io.PrintWriter;
import java.net.URL;
import java.net.URLConnection;
import java.util.List;
import java.util.Map;
public class HttpRequest {
//工具类
public static String sendGet(String url, String param) {
String result = "";
BufferedReader in = null;
try {
String urlNameString = url + "?" + param;
URL realUrl = new URL(urlNameString);
// 打开和URL之间的连接
URLConnection connection = realUrl.openConnection();
// 设置通用的请求属性
connection.setRequestProperty("accept", "*
public static String sendPost(String url, String param) {
PrintWriter out = null;
BufferedReader in = null;
String result = "";
try {
URL realUrl = new URL(url);
// 打开和URL之间的连接
URLConnection conn = realUrl.openConnection();
// 设置通用的请求属性
conn.setRequestProperty("accept", "*/*");
conn.setRequestProperty("connection", "Keep-Alive");
conn.setRequestProperty("user-agent",
"Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1;SV1)");
// 发送POST请求必须设置如下两行
conn.setDoOutput(true);
conn.setDoInput(true);
// 获取URLConnection对象对应的输出流
out = new PrintWriter(conn.getOutputStream());
// 发送请求参数
out.print(param);
// flush输出流的缓冲
out.flush();
// 定义BufferedReader输入流来读取URL的响应
in = new BufferedReader(
new InputStreamReader(conn.getInputStream()));
String line;
while ((line = in.readLine()) != null) {
result += line;
}
} catch (Exception e) {
System.out.println("发送 POST 请求出现异常！"+e);
e.printStackTrace();
}
//使用finally块来关闭输出流、输入流
finally{
try{
if(out!=null){
out.close();
}
if(in!=null){
in.close();
}
}
catch(IOException ex){
ex.printStackTrace();
}
}
return result;
}
}
二、service接口层实现
//向数据库添加数据 传值指定插入多少 integer获取的值得数量
public void insertAddPKey(Integer integer) throws JSONException{
//向第三方发送请求获取数据
String string = HttpRequest.sendGet("http://data.zuolin.com/datav/v1/social/getLatestActivityList",
//拼接URL
"jwt=eyJ0eXAiOiJKV1QiLCJhbGciOiJIUzI1NiJ9.eyJpYXQiOjE1NjQ0NTc1NjcsIm5iZiI6MTU2NDQ1NzU2N"
+ "ywianRpIjoiZGU3ZTIwNGYtZmU5Ny00NjRjLTk1NDctOTZhN2UxYjIyYzk0IiwiZXhwIjoxNTY3MDQ5NTY3LC"
+ "JpZGVudGl0eSI6MTA5OTk5NTUsImZyZXNoIjpmYWxzZSwidHlwZSI6ImFjY2VzcyJ9.lQr_BfP_g6cB7kuI8k"
+ "uWVQTOA6uhS8psr9FBMHaM90c&ns=1&genre=1&size="+integer);
//拼接参数
System.out.println(string.toString());
三、测试
//测试
public static void main(String[] args) {
zuolindata zuoli = new zuolinserviceImp();
zuoli.insertAddPKey(1);
}
