如何使用PHP调用API接口实现天气查询功能
最近在做微信公众平台测试时,想在里面子菜单上添加查询未来几天(包括今天)天气的功能,就查找了下好用的天气预报查询接口API,使用比较多的有:国家气象局天气接口、新浪天气预报接口、百度天气预报接口、google天气接口、Yahoo天气接口等等,我使用的是百度提供的免费天气查询接口API,下面与大家分享下...
1、查询方式:
百度提供的是根据纬度和城市名查询天气情况
2、接口事例:
3、接口参数说明:
4、返回结果说明:
5、
//城市名
$city = '上海';
//对json格式的字符串进行编码
$arr =json_decode($str,TRUE);
print_r($atr);
//城市名
$city = '上海';
//获取json格式的数据
$str =file_get_contents("".$city."output=jsonak=5slgyqGDENN7Sy7pw29IUvrZ");
//对json格式的字符串进行编码
$arr =json_decode($str,TRUE);
print_r($atr);
6、返回页面的是json编码后的数据:
[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, 实时:19℃)
[dayPictureUrl] =
[nightPictureUrl] =
[weather] = 晴
[wind] = 西南风3-4级
[temperature] = 13℃
)
[1] = Array
(
[date]= 周二
[dayPictureUrl] =
[nightPictureUrl] =
[weather]= 多云转阴
[wind]= 东北风3-4级
[temperature] = 24 ~ 9℃
)
[2] = Array
(
[date]= 周三
[dayPictureUrl] =
[nightPictureUrl] =
[weather]= 中雨转小雨
[wind]= 东北风3-4级
[temperature] = 15 ~ 8℃
)
[3] = Array
(
[date]= 周四
[dayPictureUrl] =
[nightPictureUrl] =
[weather]= 多云转晴
[wind]= 北风3-4级
[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, 实时:19℃)
[dayPictureUrl] =
[nightPictureUrl] =
[weather] = 晴
[wind] = 西南风3-4级
[temperature] = 13℃
)
[1] = Array
(
[date]= 周二
[dayPictureUrl] =
[nightPictureUrl] =
[weather]= 多云转阴
[wind]= 东北风3-4级
[temperature] = 24 ~ 9℃
)
[2] = Array
(
[date]= 周三
[dayPictureUrl] =
[nightPictureUrl] =
[weather]= 中雨转小雨
[wind]= 东北风3-4级
[temperature] = 15 ~ 8℃
)
[3] = Array
(
[date]= 周四
[dayPictureUrl] =
[nightPictureUrl] =
[weather]= 多云转晴
[wind]= 北风3-4级
[temperature] = 14 ~ 6℃
)
)
)
)
)
7、PHP中自带了处理json格式字符串的内置函数,下面做一个事例,并给出完整代码:
[php] view plain copy print?
metacharset="UTF-8"
?php
//城市名
$city = '上海';
//获取json格式的数据
$str = file_get_contents("".$city."output=jsonak=5slgyqGDENN7Sy7pw29IUvrZ");
//对json格式的字符串进行编码
$arr = json_decode($str,TRUE);
echo "城市:".$arr['results'][0]['currentCity']." 日期:".$arr['date']."br /br /";
foreach($arr['results'][0]['weather_data']as $val)
{
echo $val['date']."br/";
echo "天气:{$val['weather']}br/";
echo "风向:{$val['wind']}br/";
echo "温度:{$val['temperature']}br/br /";
}
?
metacharset="UTF-8"
?php
//城市名
$city = '上海';
//获取json格式的数据
$str = file_get_contents("".$city."output=jsonak=5slgyqGDENN7Sy7pw29IUvrZ");
//对json格式的字符串进行编码
$arr = json_decode($str,TRUE);
echo "城市:".$arr['results'][0]['currentCity']." 日期:".$arr['date']."br /br /";
foreach($arr['results'][0]['weather_data']as $val)
{
echo $val['date']."br/";
echo "天气:{$val['weather']}br/";
echo "风向:{$val['wind']}br/";
echo "温度:{$val['temperature']}br/br /";
}
?
8、返回的内容如下:
谁帮我找一个天气预报网页代码
代码如下:
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的代码.在那里上网就显示那里的天气
