开放平台，可以利用现在网络上的各种工具接口，为自己的公众平台增加亮点。天气查询，快递查询，手机归属地查询，身份证查询，公交查询，火车查询，健康指数查询，实时翻译(语音)，百度百科，百度问答，人品计算，笑话……等接口开发都已经成熟了。 今天我们先来看看最简单普遍的天气预报功能
中国天气网天气预报接口（官方接口）
请求地址： /data/101010100.html
首先我们创建一个类。
保存为：weather.class.php 天气预报的处理类
<?php
// 天气类
class getweather{
public function getw($str){
if ($code){
$content = file_get_contents("/data/{$code}.html");
if(!$content){
file_put_contents('', '没有接受到天气数据', FILE_APPEND); return '爱油，抱歉，暂时没有取到天气数据,请稍后再试';
}
$result=json_decode($content,true);
$info=$result['weatherinfo'];
//文本形式
$strw="{$info['date_y']} {$info['week']} \n{$info['city']}的天气情况\n";
$strw .= "今天：({$info['temp1']}){$info['weather1']}{$info['wind1']}{$info['fl1']}。\n";
$strw .= "明天：({$info['temp2']}){$info['weather2']}{$info['wind2']}{$info['fl2']}。\n";
return $strw;
}else{
return '没有获取到该城市的天气,请确定输入了正确的城市名称,如\'福州天气\'';
}
}
/**
* 验证接受到的数据是否合法
* @param string $str 传入的接受到的数据
* @return mixed|boolean 有数据返回$code,没有数据返回false;
*
*/
private function check($str){
// 引入天气代码数组
include"city_code.php";
if (is_array($CSArr)) {
return array_search($str, $CSArr);
}else {
return false;
}
}
}
?>
