如何做一个api接口?

本文目录一览:
中国国家气象局提供了获取所在城市天气预报信息接口。通过这个接口,我们就可以获取天气信息了。
关于获取天气预报的实例参考android学习手册,里面有源码。android学习手册包含9个章节,108个例子,源码文档随便看,例子都是可交互,可运行,源码采用android studio目录结构,高亮显示代码,文档都采用文档结构图显示,可以快速定位。360手机助手中下载,图标上有贝壳
中国国家气象局天气预报接口总共提供了三个:
http://www.weather.com.cn/data/sk/101010100.html
http://www.weather.com.cn/data/cityinfo/101010100.html
http://m.weather.com.cn/data/101010100.html
注:上面接口2014.3.4日已不再更新。换成这个:http://m.weather.com.cn/atad/101230201.html。各位看34楼。在此感谢tdwll和黄晓佳cobish。
最详细的信息来自第三个接口。上面url中的101010100是城市代码,这里是北京的城市代码。只需要改变城市代码,就可以得到所在城市的天气信息。笔者在福州,所以选择的城市代码是福州101230101。
在浏览器上输入url:http://m.weather.com.cn/data/101230101.html得到信息,天气信息是json的数据格式,数据如下:
{"weatherinfo":{"city":"福州","city_en":"fuzhou","date_y":"2012年5月14日","date":"","week":"星期一","fchh":"08","cityid":"101230101","temp1":"29℃~23℃","temp2":"26℃~20℃","temp3":"24℃~20℃","temp4":"25℃~20℃","temp5":"24℃~21℃","temp6":"25℃~22℃","tempF1":"84.2℉~73.4℉","tempF2":"78.8℉~68℉","tempF3":"75.2℉~68℉","tempF4":"77℉~68℉","tempF5":"75.2℉~69.8℉","tempF6":"77℉~71.6℉","weather1":"阵雨转中雨","weather2":"中雨转小雨","weather3":"小雨","weather4":"小雨","weather5":"小雨转阵雨","weather6":"阵雨转小雨","img1":"3","img2":"8","img3":"8","img4":"7","img5":"7","img6":"99","img7":"7","img8":"99","img9":"7","img10":"3","img11":"3","img12":"7","img_single":"3","img_title1":"阵雨","img_title2":"中雨","img_title3":"中雨","img_title4":"小雨","img_title5":"小雨","img_title6":"小雨","img_title7":"小雨","img_title8":"小雨","img_title9":"小雨","img_title10":"阵雨","img_title11":"阵雨","img_title12":"小雨","img_title_single":"阵雨","wind1":"微风","wind2":"微风","wind3":"微风","wind4":"微风","wind5":"微风","wind6":"微风","fx1":"微风","fx2":"微风","fl1":"小于3级","fl2":"小于3级","fl3":"小于3级","fl4":"小于3级","fl5":"小于3级","fl6":"小于3级","index":"热","index_d":"天气较热,建议着短裙、短裤、短套装、T恤等夏季服装。年老体弱者宜着长袖衬衫和单裤。","index48":"暖","index48_d":"较凉爽,建议着长袖衬衫加单裤等春秋过渡装。年老体弱者宜着针织长袖衬衫、马甲和长裤。","index_uv":"弱","index48_uv":"最弱","index_xc":"不宜","index_tr":"适宜","index_co":"较不舒适","st1":"27","st2":"21","st3":"24","st4":"18","st5":"22","st6":"18","index_cl":"较不宜","index_ls":"不太适宜","index_ag":"不易发"}}
我们可以解析json数据去得到自己想用的天气信息。

提交后得到API Key ,运行结果如下:
扩展资料:
API(Application Programming Interface,应用程序编程接口)是一些预先定义免费api天气接口的函数,目免费api天气接口的是提供应用程序与开发人员基于某软件或硬件得以访问一组例程免费api天气接口的能力,而又无需访问源码,或理解内部工作机制的细节。
API函数包含在Windows系统目录下的动态连接库文件中。Windows API是一套用来控制Windows的各个部件的外观和行为的预先定义的Windows函数。

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] =http://api.map.baidu.com/images/weather/day/qing.png
[nightPictureUrl] =http://api.map.baidu.com/images/weather/night/qing.png
[weather] = 晴
[wind] = 西南风3-4级
[temperature] = 13℃
)
[1] = Array
(
[date]= 周二
[dayPictureUrl] =http://api.map.baidu.com/images/weather/day/duoyun.png
[nightPictureUrl] = http://api.map.baidu.com/images/weather/night/yin.png
[weather]= 多云转阴
[wind]= 东北风3-4级
[temperature] = 24 ~ 9℃
)
[2] = Array
(
[date]= 周三
[dayPictureUrl] =http://api.map.baidu.com/images/weather/day/zhongyu.png
[nightPictureUrl] = http://api.map.baidu.com/images/weather/night/xiaoyu.png
[weather]= 中雨转小雨
[wind]= 东北风3-4级
[temperature] = 15 ~ 8℃
)
[3] = Array
(
[date]= 周四
[dayPictureUrl] =http://api.map.baidu.com/images/weather/day/duoyun.png
[nightPictureUrl] =http://api.map.baidu.com/images/weather/night/qing.png
[weather]= 多云转晴
[wind]= 北风3-4级
[temperature] = 14 ~ 6℃
)
)
)
)
)
<meta charset="UTF-8"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
$str = file_get_contents("http://api.map.baidu.com/telematics/v3/weather?location=".$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"8、返回的内容如下:
