首先可以明确一点,所有的气象数据一定都是来自官方的,以非官方名义公布天气数据应该还没有人敢,只是国家天气数据也有不准的时候,所有的公司都面临一个问题,怎么样让自己的数据比竞品更准?1、国家天气数据为什么也会不准?

国家天气数据中的一部分是地面、高空、雷达观测数据,会自动汇总到国家气象信息中心通信台。

一部分是卫星数据,比如中国的风云卫星一般需要20多分钟才能完成全球扫描,所以这部分的数据通常有半小时左右的延迟。

最后是预报数据,气象学上有一些标准模型,跑模型的时间,数据打包传输分发的时间其实是比较长的(由于数据量的关系),比如气象局可能采用欧洲中心模式系统的数据,有一些延迟,但是预报的特性就是随着时间不断接近,预测越是准确,很容易理解。就我所知,国家高校的一些研究机构也有自己的模型,也不敢说哪个就一定是最准的。

(一部分信息来自中国气象网)

2、国家天气数据可能是不全面的

有些时候我们想要通过手机传感器获得的经纬度来获取天气数据,或者通过?IP?地址来获取天气数据,这些都是很常见的需求,而国家天气数据的?API?可能不支持。

或者,地方气象台有一些地方的气象数据,它们属于省级气象数据,并不需要上报到国家级,那么自然国家天气数据的?API?不支持,但是地方依旧会公布它们。

亦或者,很多人关心 PM2.5,这些数据不是来自气象局,而是来自环保局,而且环保局还没有空气质量预报,又要从其他机构接入。

Android weather API 昨天好像发现 m.weather.com.cn/data

如何使用百度天气预报API接口

这是官方论坛上的通知,那个接口已经停用,可以申请新的接口使用,谢谢。

致广大气象开发爱好者:

近期很多网友反馈该地址的数据不更新,特此声明,该地址并非官方发布的面向公众的数据接口。后续将不在维护!

如需使用天气数据,请到官方正式对外提供的平台(SmartWeatherAPI平台),按固定格式填写表格申请使用:

申请地址:

该接口免费向公众提供3天天气预报、实况、指数等数据信息,如需申请开通更多数据接口,请走商务合作渠道!

感谢大家配合!

3. ?我们来写个demo,代码如下:

package com.example.administrator.jsontest;

public class MainActivity extends Activity {

private Button button;

private TextView textView;

private Handler handler = new Handler() {

@Override

public void handleMessage(Message msg) {

switch (msg.what) {

case 0:

String re = (String) msg.obj;

textView.setText(re);

break;

}

}

};

@Override

protected void onCreate(Bundle savedInstanceState) {

super.onCreate(savedInstanceState);

setContentView(R.layout.activity_main);

button = (Button) findViewById(R.id.button);

textView = (TextView) findViewById(R.id.textView);

button.setOnClickListener(new View.OnClickListener() {

@Override

public void onClick(View v) {

Log.i("TAG", "点击了Button");

sendRequestWithHttpClient();

}

});

}

private void sendRequestWithHttpClient() {

new Thread(new Runnable() {

@Override

public void run() {

HttpURLConnection connection = null;

try {

URL url = new URL("南昌&output=json&ak=8ixCCFzlBB617YX7tONI2P5B&mcode=1C:6B:42:33:E8:A6:DC:A2:11:6E:26:EC:84:BD:42:E3:8E:6B:57:9A;com.example.administrator.jsontest");

connection = (HttpURLConnection) url.openConnection();

connection.setRequestMethod("GET");

connection.setConnectTimeout(5000);

connection.setReadTimeout(5000);

InputStream in = connection.getInputStream();

BufferedReader reader = new BufferedReader(new InputStreamReader(in));

StringBuilder response = new StringBuilder();

String line;

while ((line = reader.readLine()) != null) {

response.append(line);

}

Log.i("TAG", response.toString()); parseJSONObjectOrJSONArray(response.toString());

} catch (MalformedURLException e) {

e.printStackTrace();

} catch (IOException e) {

e.printStackTrace();

}

}

}).start();

}

//解析JSON数据

private void parseJSONObjectOrJSONArray(String jsonData) {

try {

String count = "";

JSONObject jsonObject = new JSONObject(jsonData);

JSONArray jsonArray = jsonObject.getJSONArray("results");

if (jsonArray.length() > 0) {

JSONObject object = jsonArray.getJSONObject(0);

String city = object.optString("currentCity");

JSONArray array = object.getJSONArray("weather_data");

for (int i = 0; i < array.length(); i++) {

JSONObject jsonObject1 = array.getJSONObject(i);

String dateDay = jsonObject1.optString("date");

String weather = jsonObject1.optString("weather");

String wind = jsonObject1.optString("wind");

String temperature = jsonObject1.optString("temperature");

count =count +"\n"+ dateDay + " " + weather + " " + wind + " " + temperature;

Log.i("AAA",count);

}

Message message = new Message();

message.what = 0;

message.obj = count;

handler.sendMessage(message);

}

} catch (JSONException e) {

e.printStackTrace();

}

}

}

4.?运行结果如下:?

因微信公共号提供城市天气预报服务,发现网山天气预报接口和环境数据接口方面资料比较乱,而且有不少内容已经失效,下面内容由过程日志整理形成,希望可用得上。

一 天气预报

国内的天气预报数据,主要是国家气象局和国外两个来源(指数据来源)。

国外方面主要是雅虎(XML格式,谷歌已经停掉了自家的天气API);

国内数据由国家气象局提供(JSON格式)。

在知乎看到过一篇专业人士评论,雅虎可以提供全球范围的且非常精细的天气数据(小时级更新),但主要是通过计算机自动生成。而国家气象局则是各地经验丰富的专家人士结合计算机综合分析得出,在准确性上更胜一筹。我就这样信了!

国家气象局接口资源及用法

特点:接口多,来自weather.com.cn和mobile.weather.com.cn都有,次数不限制,服务稳定,功能全面,优先推荐。
