通過XML接口根節點遞歸獲得全國幾千個縣以上城市cide code的代碼
如何使用PHP調用API接口實現天氣查詢功能
最近在做微信公眾平台測試時，想在裡面子菜單上添加查詢未來幾天（包括今天）天氣的功能，就查找了下好用的天氣預報查詢接口API，使用比較多的有：國家氣象局天氣接口、新浪天氣預報接口、百度天氣預報接口、google天氣接口、Yahoo天氣接口等等，我使用的是百度提供的免費天氣查詢接口API，下面與大家分享下…
1、查詢方式：
百度提供的是根據緯度和城市名查詢天氣情況
2、接口事例：
3、接口參數說明：
4、返回結果說明：
5、
//城市名
$city = ‘上海’;
//對json格式的字符串進行編碼
$arr =json_decode($str,TRUE);
print_r($atr);
//城市名
$city = ‘上海’;
//獲取json格式的數據
$str =file_get_contents(“”.$city.”output=jsonak=5slgyqGDENN7Sy7pw29IUvrZ”);
//對json格式的字符串進行編碼
$arr =json_decode($str,TRUE);
print_r($atr);
6、返回頁面的是json編碼後的數據：
[plain] view plain copy print?
meta charset=”UTF-8″
Array
(
[error] = 0
[status] = success
[date] = 2014-03-17
[results] = Array
(
[0] = Array
(
[currentCity]= 上海
[weather_data]= Array
(
[0]= Array
(
[date] = 周一(今天, 實時：19℃)
[dayPictureUrl] =
[nightPictureUrl] =
[weather] = 晴
[wind] = 西南風3-4級
[temperature] = 13℃
)
[1] = Array
(
[date]= 周二
[dayPictureUrl] =
[nightPictureUrl] =
[weather]= 多雲轉陰
[wind]= 東北風3-4級
[temperature] = 24 ~ 9℃
)
[2] = Array
(
[date]= 周三
[dayPictureUrl] =
[nightPictureUrl] =
[weather]= 中雨轉小雨
[wind]= 東北風3-4級
[temperature] = 15 ~ 8℃
)
[3] = Array
(
[date]= 周四
[dayPictureUrl] =
[nightPictureUrl] =
[weather]= 多雲轉晴
[wind]= 北風3-4級
[temperature] = 14 ~ 6℃
)
)
)
)
)
meta charset=”UTF-8″
Array
(
[error] = 0
[status] = success
[date] = 2014-03-17
[results] = Array
(
[0] = Array
(
[currentCity]= 上海
[weather_data]= Array
(
[0]= Array
(
[date] = 周一(今天, 實時：19℃)
[dayPictureUrl] =
[nightPictureUrl] =
[weather] = 晴
[wind] = 西南風3-4級
[temperature] = 13℃
)
[1] = Array
(
[date]= 周二
[dayPictureUrl] =
[nightPictureUrl] =
[weather]= 多雲轉陰
[wind]= 東北風3-4級
[temperature] = 24 ~ 9℃
)
[2] = Array
(
[date]= 周三
[dayPictureUrl] =
[nightPictureUrl] =
[weather]= 中雨轉小雨
[wind]= 東北風3-4級
[temperature] = 15 ~ 8℃
)
[3] = Array
(
[date]= 周四
[dayPictureUrl] =
[nightPictureUrl] =
[weather]= 多雲轉晴
[wind]= 北風3-4級
[temperature] = 14 ~ 6℃
)
)
)
)
)
7、PHP中自帶了處理json格式字符串的內置函數，下面做一個事例，並給出完整代碼：
[php] view plain copy print?
metacharset=”UTF-8″
?php
//城市名
$city = ‘上海’;
//獲取json格式的數據
$str = file_get_contents(“”.$city.”output=jsonak=5slgyqGDENN7Sy7pw29IUvrZ”);
//對json格式的字符串進行編碼
$arr = json_decode($str,TRUE);
echo “城市:”.$arr[‘results’][0][‘currentCity’].” 日期：”.$arr[‘date’].”br /br /”;
foreach($arr[‘results’][0][‘weather_data’]as $val)
{
echo $val[‘date’].”br/”;
echo “天氣：{$val[‘weather’]}br/”;
echo “風向：{$val[‘wind’]}br/”;
echo “溫度：{$val[‘temperature’]}br/br /”;
}
?
metacharset=”UTF-8″
?php
//城市名
$city = ‘上海’;
//獲取json格式的數據
$str = file_get_contents(“”.$city.”output=jsonak=5slgyqGDENN7Sy7pw29IUvrZ”);
//對json格式的字符串進行編碼
$arr = json_decode($str,TRUE);
echo “城市:”.$arr[‘results’][0][‘currentCity’].” 日期：”.$arr[‘date’].”br /br /”;
foreach($arr[‘results’][0][‘weather_data’]as $val)
{
echo $val[‘date’].”br/”;
echo “天氣：{$val[‘weather’]}br/”;
echo “風向：{$val[‘wind’]}br/”;
echo “溫度：{$val[‘temperature’]}br/br /”;
}
?
8、返回的內容如下：
誰幫我找一個天氣預報網頁代碼
代碼如下：
iframe id=weatherwin border=0 name=weatherwin marginWidth=0 marginHeight=0 src=”” frameBorder=no width=160 scrolling=no height=60/iframe
也可以用265.com的代碼.在那裡上網就顯示那裡的天氣
