First of all, we must understand that we cannot do weather forecasting by ourselves. Here we only need to call the data returned by the API interface. The following is an example of calling the API interface of China Weather Network for us to learn together. Weather has become an indispensable topic in life and is closely related to our lives. On the right side of my blog, I made a small weather query module using php+ajax.

The ideal state should be for users to automatically obtain local weather information based on different places they visit. However, the technology is currently limited and can only be completed manually. This is much simpler and does not use too many technologies. It mainly uses ajax to call an open interface and then processes the returned json data.

Interface address: http://www.weather.com.cn/data/cityinfo/101200101.html

Returned value: {"weatherinfo":{"city":"Wuhan","cityid":"101200101","temp1":"28℃","temp2":"36℃", "weather":"Sunny to cloudy","img1":"n0.gif","img2":"d1.gif","ptime":"18:00"}}

The interface address part is "101200101". This string of ID numbers is the city ID. I went to Baidu to get the ID corresponding to the city, and then encapsulated it into an array. When using it, just call it directly. There is not much core code, mainly cities - IDs are relatively large, so I won’t post the source code, just package it and share it. Friends who need it can download it directly!

Part of the code

The code is as follows

//echo "shibushi";
if(empty($citycode)){
echo "您输入的城市不在范围内";
}else{
echo file_get_contents("http://www.weather.com.cn/data/cityinfo/".$citycode.".html");
}
