Where are mobile cookies hiding? Let me tell you a big secret!

In today’s mobile Internet era, mobile phones have become an indispensable part of people’s lives. When using mobile phones to surf the Internet, we often encounter situations where we need to log in, such as shopping, social media, banking and other applications. The storage of login information requires cookies. So, where are the cookies on your phone hidden? Today I'm going to reveal the big secret and give you a concrete code example.

First of all, we need to make it clear that cookies are actually stored in the mobile phone's browser. There may be some differences between different mobile phone systems and different browsers. Let's take the Chrome browser that comes with the Android system as an example to illustrate.

1. First of all, we need to install the Chrome browser on the phone and open a web page.
2. Click the menu button in the upper right corner of the browser and select the "Settings" option.
3. In the settings interface, slide down to find and click the "Website Settings" option.
4. In the website settings interface, click the "Cookie" option.
5. At this time, we can see all the cookie information stored in the mobile phone. These cookies can be viewed and deleted as needed.

Of course, if we want to access the cookies in the mobile phone through code, it can also be achieved. The specific code examples are as follows (taking Java language as an example):

----------------------Code to start accessing Cookie information--- ------------------

import android.webkit.CookieManager; // 获取CookieManager对象 CookieManager cookieManager = CookieManager.getInstance(); // 获取当前网页的URL String url = "https://www.example.com"; // 根据URL获取该网页的Cookie信息 String cookie = cookieManager.getCookie(url); // 打印Cookie信息 System.out.println(cookie);

----------------------End of visit Code for cookie information----------------------

Through the above code, we can obtain the cookie information of the specified web page and perform it in the console Printout. If we want to delete the cookie information of a specific web page, we can also use a similar method to achieve it. The specific code examples are as follows:

------------------- ---Code to start deleting cookie information----------------------

import android.webkit.CookieManager; // 获取CookieManager对象 CookieManager cookieManager = CookieManager.getInstance(); // 获取当前网页的URL String url = "https://www.example.com"; // 删除该网页的所有Cookie信息 cookieManager.removeAllCookies(null); // 删除指定名称的Cookie信息 cookieManager.setCookie(url, "cookie_name=; expires=Thu, 01 Jan 1970 00:00:00 UTC"); // 刷新网页 webView.reload();

------------ ----------End the code for deleting cookie information----------------------

With the above code, we can Delete the cookie information of the specified web page and refresh the web page to make the modification effective.

In short, the cookies on the mobile phone are actually stored in the mobile browser. We can view and delete this cookie information through the browser's settings interface. At the same time, if we need to access and modify the cookie information in the mobile phone through code, we can also use related class libraries and methods to achieve this.
