天气Api http://apicloud.mob.com/v1/weather/ip?key=270c4d225bcf0&ip=“ip”
更换ip
后台获取ip的方法：
request.getRemoteAddr()；
前台获取ip的方法：
java后台访问网站的方法：
public static String SendGET(){
String result=””;//访问返回结果
BufferedReader read=null;//读取访问结果
try {
//创建url
URL realurl=new URL("http://apicloud.mob.com/v1/weather/ip?key=270c4d225bcf0&ip=121.123.92.228");
//打开连接
URLConnection connection=realurl.openConnection();
// 设置通用的请求属性
connection.setRequestProperty("accept", "*/*");
connection.setRequestProperty("connection", "Keep-Alive");
connection.setRequestProperty("user-agent",
"Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1;SV1)");
//建立连接
connection.connect();
// 获取所有响应头字段
Map<String, List<String>> map = connection.getHeaderFields();
// 遍历所有的响应头字段，获取到cookies等
for (String key : map.keySet()) {
System.out.println(key + "--->" + map.get(key));
}
// 定义 BufferedReader输入流来读取URL的响应
read = new BufferedReader(new InputStreamReader(
connection.getInputStream(),"UTF-8"));
String line;//循环读取
while ((line = read.readLine()) != null) {
result += line;
}
} catch (IOException e) {
e.printStackTrace();
}finally{
if(read!=null){//关闭流
try {
read.close();
} catch (IOException e) {
e.printStackTrace();
}
}
}
return result;
}
