天气预报代码调用查询_天气预报代码url调用
1.网站想调用一个天气预报的代码,请问哪个网站提供免费代码或是天气插件
2.怎么样用vb语言编写 获取当今的天气预报
3.ASP.NET实现天气预报
4.谁帮我找一个天气预报网页代码
5.求~一行天气预报代码(附参考站)
6.如何使用百度天气预报API接口
直接使用插件,如
<iframe width="214" scrolling="no" height="54" frameborder="0" allowtransparency="true" src="://i.tianqi/index.php?c=code&id=42&icon=1&num=3"></iframe>
效果如下
这个插件来源是://.tianqi/plugin/
网站想调用一个天气预报的代码,请问哪个网站提供免费代码或是天气插件
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
<h1>...</h1>标题字(最大 )
<h6>...</h6>标题字(最小)
<b>...</b>粗体字
<strong>...</strong>粗体字(强调)
<br>(换行)
<nobr>...</nobr>水域(不换行)
<p>...</p>水域(段落)
<center>...</center>置中

怎么样用vb语言编写 获取当今的天气预报
这里的天气预报调用支持DIY样式,并支持IP显示天气,根据用户所在地显示当前天气预报!
://t.xidie/WeatherCode.aspx
样式挺多的。
ASP.NET实现天气预报
首先你想获取当今的天气预报 你发布在网页制作 我姑且是以为你做的是vb.net 网页程序其次 获取当今的天气预报 都是调用各大网站给出的接口 (不会有人自己去整理这些资料的吧)最后 接口的使用 如果是软件 可以调用 WEB服务接口(各网站有) 网页也可以调用这些接口(实现方法输入城市地址,返回天气)还有更简单的 直接使用我给出一个简单框架代码实现:新浪天气预报代码 代码 :://news.sina.cn/iframe/weather/130101.html"></A>

代码如下:

也可以用265的代码.在那里上网就显示那里的天气
如何使用百度天气预报API接口
发送到这个网站的一个网址,会自动返回此城市的天气信息。对此信息再格式化就好了。
发送:://main.mapbar/weather.jsp?city=广州
返回:b4.gif^广州^雷阵雨^26℃ ~ 22℃^微风^紫外线:弱
发送:://main.mapbar/weather.jsp?city=上海
返回:b3.gif^上海^阵雨转阴^16℃ ~ 13℃^东南风3-4级^紫外线:最弱
至于如何判断访问者是哪一个城市,需要分析其IP地址然后再加判断吧,你到网上找个IP转城市的数据库看看。
百度API Key申请地址:://lbsyun.baidu/apiconsole/key

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++) {

}
Message message = new Message();

handler.sendMessage(message);
}
} catch (JSONException e) {
