java对第三方数据接口进行加密，具体方法如下：

package com.c;
import java.io.BufferedReader;
import java.io.InputStream;
import java.io.InputStreamReader;
import java.io.PrintWriter;
import java.net.HttpURLConnection;
import java.net.URL;
public static void interfaceUtil(String path,String data) {
try {
URL url = new URL(path);
//打开和url之间的连接
HttpURLConnection conn = (HttpURLConnection) url.openConnection();
PrintWriter out = null;
//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)"); 
conn.setDoOutput(true);
conn.setDoInput(true);
//获取URLConnection对象对应的输出流
out = new PrintWriter(conn.getOutputStream());
//发送请求参数即数据
out.print(data);
//缓冲数据
out.flush();
//获取URLConnection对象对应的输入流
InputStream is = conn.getInputStream();
//构造一个字符流缓存
BufferedReader br = new BufferedReader(new InputStreamReader(is));
String str = "";
while ((str = br.readLine()) != null) {
System.out.println(str);
}
//关闭流
is.close();
//断开连接
conn.disconnect();
System.out.println("完整结束");
} catch (Exception e) {
e.printStackTrace();
}
}
public static void main(String[] args) {
interfaceUtil("http://api.map.baidu.com/telematics/v3/weather?location=嘉兴&output=json&ak=5slgyqGDENN7Sy7pw29IUvrZ", "");
}
}
