import java.io.BufferedReader;
import java.io.InputStream;
import java.io.InputStreamReader;
import java.util.HashMap;
import java.util.Map;

import org.apache.http.HttpEntity;
import org.apache.http.HttpResponse;

/**

public class weather {

public static void main(String[] args) {
System.out.println(getWeather("杭州市"));
}

public static String getWeather(String name) {
String host = "http://jisutqybmf.market.alicloudapi.com";
String path = "/weather/query";
String method = "GET";
String appcode = "你的appcode";
Map<String, String> headers = new HashMap<String, String>();
headers.put("Authorization", "APPCODE " + appcode);
Map<String, String> querys = new HashMap<String, String>();
querys.put("city", name);
try {
HttpResponse response = HttpUtils.doGet(host, path, method, headers, querys);
HttpEntity httpEntity = response.getEntity();
// 将HttpEntity中返回实体转化为输入流
InputStream is = httpEntity.getContent();
// 读取输入流，即返回文本内容
BufferedReader br = new BufferedReader(new InputStreamReader(is));
return br.readLine().toString();
} catch (Exception e) {
e.printStackTrace();
return "";
}
}
