PHP ajax achieves no refresh to obtain weather status_PHP tutorial

ajaxphprefreshweatherweather forecastaccomplishusyesstateObtainwantfirst

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 Copy code

getweather.php文件

 请输入城市:
 


为、

 include "citycode.php";
 $city = $_POST['city'];
 $citycode = @$citycode[$city];
 //echo "shibushi";
 if(empty($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");
 }
?>


 请输入城市:
 


为、  include "citycode.php";
 $city = $_POST['city'];
 $citycode = @$citycode[$city];
 //echo "shibushi";
 if(empty($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");
 }
?>

Select DependencyInjection (DI) for large applications, ServiceLocator is suitable for small projects or prototypes. 1) DI improves the testability and modularity of the code through constructor injection. 2) ServiceLocator obtains services through center registration, which is convenient but may lead to an increase in code coupling.

PHP Dependency Injection: Improve Code TestabilityPHP Dependency Injection: Improve Code TestabilityMay 12, 2025 am 12:03 AM

Dependency injection (DI) significantly improves the testability of PHP code by explicitly transitive dependencies. 1) DI decoupling classes and specific implementations make testing and maintenance more flexible. 2) Among the three types, the constructor injects explicit expression dependencies to keep the state consistent. 3) Use DI containers to manage complex dependencies to improve code quality and development efficiency.

SecLists

SecLists is the ultimate security tester's companion. It is a collection of various types of lists that are frequently used during security assessments, all in one place. SecLists helps make security testing more efficient and productive by conveniently providing all the lists a security tester might need. List types include usernames, passwords, URLs, fuzzing payloads, sensitive data patterns, web shells, and more. The tester can simply pull this repository onto a new test machine and he will have access to every type of list he needs.
