一：首先到气象数据平台申请

AppId：8908902c30853b5 
Private_Key：890890_SmartWeatherAPI_890890
使用时换为自己申请的即可

二：订购常规气象数据接口

三：气象使用说明

1、调用规范规范用于指导三方合作伙伴合理调用指数、3天常规预报(24小时)预报服务数据。
请求方式：http get
接口组成：由固定URL加5个不同的参数组成，完整URL需客户端经过固定方式加密后使用。
数据返回：json
完整URL：http://open.weather.com.cn/data/?areaid=""&type=""&date=""&appid=""&key=".urlencode($key);
固定URL：http://open.weather.com.cn/data/

参数名称	参数含义	参数样例
Areaid	区域id	单区域:101010100；多区域:101010100\|101010200
Type	数据类型	指数:index_f(基础接口)；index_v(常规接口)； 3天预报:forecast_f(基础接口)；forecast_v(常规接口)；
Date	客户端日期	按照格式yyyyMMddHHmm获取客户端当前时间
Appid	固定分配的型号标识	某某:004906671841487 传递参数时:截取appid的前6位生成公钥时:取完整的appid
Key	令牌	由公钥(public_key)和私钥(private_key)通过固定算法加密生成

加密方式:
private_key
某某:793ffb_SmartWeatherAPI_662cbc7
private_key仅负责与public_key共同合成key传参，私钥不可见，客户端与服务端各存储一份;
public_key为不包含key在内的完整URL其它部分（此处appid为完整appid）
示例:
http://open.weather.com.cn/data/?areaid=101010100&type=index_f&date=201410230335&appid=22290667181111 key的算法
key=base64_encode(hash_hmac('sha1',$public_key,$private_key,TRUE));
key加密后通过urlencode对其编码后传参
注：每一个产品使用用户分配一个唯一标识appid,用于统计用户访问情况、区分用户提供差异服务，终端用户按照终端型号分配，一个型号对应一个标识。

返回参数说明书

四：编写JSON接口

<?php

date_default_timezone_set('PRC');
require_once 'Cache.class.php';

    const TYPE = "forecast_v"; //基础气象数据接口：type=forecast_f;常规气象数据接口：type=forecast_v

五：XML接口

　　1. XML接口
　　http://flash.weather.com.cn/wmaps/xml/china.xml　　这个是全国天气的根节点，列出所有的省，其中的pyName字段是各个省XML的文件名，比如陕西的是sanxi，那就意味着陕西的XML地址为
　　http://flash.weather.com.cn/wmaps/xml/sanxi.xml
　　一个省的天气，其中列出该省各个市的数据，北京,上海，天津等就列出各个区。那就意味着西安的XML地址为

　　http://flash.weather.com.cn/wmaps/xml/xian.xml

　　tmp1是最高温低，tmp2是最低温度，temNow是实时温度。
