SMATERWEATHERAPI---Signature encryption and data access--a simple and brutal step

Use China Weather Network interface Friends, everyone (and i) hard

If you are interested, you can get to know http://smart.weather.com.cn/wzfw/smart/weatherapi.shtml.

At the beginning of the year stopped using the previous interface, instead of applying for use, so sent a request for mail, the middle of various twists ... 10,000 words:

Finally the application came down, but the interface document AH, see I feel tired not love, the document only PHP version of the Kay generation method, I use on the Androi, those encryption methods do not know how to implement Java

Rage, just write a PHP version of it, originally was just want to write a generator key interface, and later thought to want to write a few lines directly to a step, eliminating the client on the multi-step network operation and string splicing

For half a day, just look at the effect.

Example:

Full code:

<?php/*----------This file need to be uploaded to their own external network space, no words can be the entire free cloud space I use the magic of the--------------*//*----------role: Access to this file only need to pass type and Areaid These two parameters, can be directly to the weather data/not to go back and forth the signature splicing and so on a lot of trouble things--------------*///China Weather Network SMARTWEATHERAPI Signature interface//signature generated direct access data// Parameter type: request data type; Areaid: City id//appid$app_id= ' your own AppID ';//privatekey$privatekey= ' your own Privatekey '; if (isset request[' type ']) &&isset ($_request[' Areaid ')) {//Receive parameter $type=$_request[' type ']; $areaid =$_request[' Areaid ' ];//formatting the current time yyyymmddhhmm$date=date (' Ymdhi ', Times ())//api request a fixed section $api_head= ' http://open.weather.com.cn/data/?
