Since Windows 8 was released, a large part of its functions have been designed for touch screens. However, Microsoft has not neglected the PC experience. This time, we skipped the traditional text password to experience the image password and simple PIN code operated by the mouse.
First, let's take a look at how to set the image password.Click your username on the Metro interface and select "Changeaccount picture" (Change account image)Then select "Us
Each boot is repeated Dial network connection this step, very troublesome; so share a little trick that makes the computer automatically connect to the network when it starts.
Operation Steps:
1, in Metro or traditional desktop, press the keyboard "win+x" combination hotkey to bring up the shortcut menu, using the left mouse button click Computer Management (G). As shown in the following picture:
2, in the Pop-up Computer Management window, using the left mouse button click on the

, except that the terms and means of implementation are not the same, such as the Interceptor Interceptor in Struts2, which is implemented by recursive stack of functions (not seen in other frameworks). The design idea is to enter the final processing method before the request through a pretreatment, in the processing method after processing after one after another, the order is exactly the opposite. A little bit topic, please see example:
1 middleware_classes = (

['code'])! = $ _ Code) {8 // The strtoupper () function converts the input letters into uppercase letters. Otherwise, the lower case is incorrect. 9 // back () function returns to the previous request page, use with to bring back the prompt information. The information is saved to 10 return back ()-> with ('msg ', 'verification code error'); 11} else {12 echo' OK '; 13} 14} else {15 16 return view ('admin. login
In fact, the most want to do is to choose the class plug-in, so this time to try to choose the course system, but the course selection system has a verification code. It's a sore egg. needs to be identified. But now you can use another method. is to download to local manual input. It only takes one time to be enough. Because the landing is successful, you can manipulate other things at will. Later, the intelligent identification of verification code is learned.The first is primarily analog logic

This example is briefly described in the previous article.
OK, let's start with the login page of the first page.
Or look at the interface
How do you really want to guide it in the end is how to achieve it? OK, let's look at the code:

What do you think of seeing this
Backend mounting: Write 8 interfaces in three lines of code !, Backend 3 rows
Some may think:
How is this possible?
Even with SpringBoot with almost zero configuration, three lines of code are required to write the simplest interface!
@RequestMapping("test/{request}") public String test(@PathVariable String request) { return request + ": Hello World"; }
There will be 24 lines of code for ei
