天气查询代码_多城市天气预报代码

1.hao123网站左上的天气预报网页代码是什么？

2.单一城市的天气预报代码怎么写?越简单越好

3.如何使用百度天气预报API接口

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！

国家气象局接口及用法

气象局的天气预报主页：移动版普通版 ,仔细挖掘这两个地址可以发现很多好东西哦。

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

1. 实时天气接口

有多个接口，好像差别不大：

实时天气1：://.weather.cn/data/sk/101190408.html

实时天气2：://.weather.cn/data/cityinfo/101190408.html

实时天气3（带时间戳）：://mobile.weather.cn/data/sk/101010100.html?_=1381891661455

2. 一周天气预报接口

7天预报数据 URL： ://mobile.weather.cn/data/forecast/101010100.html?_=1381891660081

该接口来源气象局移动版网站，目测数据最为精确，详细接口格式如下：

{"c":{"c1":"101010100","c2":"beijing","c3":"北京","c4":"beijing","c5":"北京","c6":"beijing","c7":"北京","c8":"china","c9":"中国","c10":"1","c11":"010","c12":"100000","c13":"116.391","c14":"39.904","c15":"33","c16":"AZ9010","c17":"+8"},

"f":{"f1":

{"fa":"07","fb":"07","fc":"19","fd":"12","fe":"0","ff":"0","fg":"0","fh":"0","fi":"06:22|17:38"},

"f0":"201310121100"}}

详细接口分析如下：

该接口来源网络，应该是一个流传比较久的接口，现准确性和稳定性可能不稳定。接口分析如下：

hao123网站左上的天气预报网页代码是什么？

101070301 你可以上这个站看看://.weather.cn/比如你是找鞍山的://.weather.cn/html/weather/101070301.shtml其中101070301就是你要的代码了

单一城市的天气预报代码怎么写?越简单越好

hao123网站左上的天气预报网页代码如下：

<iframe src=

"://.tianqi123/small_page/chengshi_2250.html?

c0=red&c1=D96C00&bg=F4FFF4&w=178&h=20&text=yes"?

width=178 height=21?

marginwidth=0 marginheight=0 hspace=0 vspace=0 frameborder=0 scrolling=no?

align=center id=url></iframe>

制作网页时常用的代码有HTML，JaScript，ASP，PHP，CGI等，其中超文本标记语言（标准通用标记语言下的一个应用、外语简称：HTML）是最基础的网页代码。

扩展资料：

网页代码的一些简单使用：

<marquee>...</marquee>普通卷动

<marquee behior=slide>...</marquee>滑动

<marquee behior=scroll>...</marquee>预设卷动

<marquee behior=alternate>...</marquee>来回卷动

<marquee direction=down>...</marquee>向下卷动

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 sedInstanceState) {

super.onCreate(sedInstanceState);

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("T", "点击了Button");

sendRequestWithHttpClient();

}

});

}

private void sendRequestWithHttpClient() {

new Thread(new Runnable() {

@Override

public void run() {

HttpURLConnection connection = null;

try {

URL url = new URL("://api.map.baidu/telematics/v3/weather?location=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.end(line);

}

Log.i("T", 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();

}

}

}
