这篇文章主要为大家详细介绍了php微信开发之百度天气预报的相关资料,具有一定的参考价值，感兴趣的小伙伴们可以参考一下
1.登录百度ak申请：http://lbsyun.baidu.com/apiconsole/key
2.实现天气信息功能
baiduweather.php
<?php
/**
* 使用百度天气预报接口获取城市天气信息案例实现
*/
//获取城市天气信息
function getweatherinfo($cityname){
if($cityname == "" || (strstr($cityname,"+"))){
return "发送城市加天气,例如北京天气";
}
//获取到的ak
$ak = your ak;
//获取到的sk
$sk = your sk;
//调用接口
$url = 'http://api.map.baidu.com/telematics/v3/weather?ak=%s&location=%s&output=%s&sk=%s';
$uri = '/telematics/v3/weather';
$location = $cityname;
$output = 'json';
$querystring_arrays = array(
'ak' => $ak,
'location' => $location,
'output' => $output
);
$querystring = http_build_query($querystring_arrays);
//生成sn
$sn = md5(urlencode($uri.'?'.$querystring.$sk));
$targeturl = sprintf($url,$ak,urlencode($location),$output,$sn);
$ch = curl_init();
curl_setopt($ch,curlopt_url,$targeturl);
curl_setopt($ch,curlopt_returntransfer,1);
$result = curl_exec($ch);
curl_close($ch);
$result = json_decode($result,true);
if($result["error"]!=0){
return $result["status"];
}
$curhour = (int)date('h',time());
$weather = $result["results"][0];
$weatherarray[]=array("title"=>$weather['currentcity']."天气预报","description"=>"","picurl"=>"","url"=>"");
for($i = 0;$i<count($weather["weather_data"]);$i++){
$weatherarray[] = array("title"=>
$weather["weather_data"][$i]["data"]."\n".
$weather["weather_data"][$i]["weather"].
$weather["weather_data"][$i]["wind"].
$weather["weather_data"][$i]["temperature"],
"description"=>"",
"picurl"=>(($curhour>=6)&&($curhour<
18))?$weather["weather_data"][$i]["daypictureurl"]:$weather["weather_data"][$i]["nightpictureurl"],"url"=>""
);
}
return $weatherarray;
}
3.实现天气消息事件
<?php

define("token", "weixin");
/**
* 百度天气预报案例实现
* 实现思路：
* 1.申请百度ak、sk
* 2.使用百度天气预报接口
* 3.实现天气信息功能
* 4.实现事件响应功能
