thinkphp5 determines whether it is a post request

When using ThinkPHP5 for web development, it is a common requirement to determine whether the current request is a POST request. Because POST requests are different from GET requests, POST requests are usually used to submit data to the server, while GET requests are usually used to get data from the server. Therefore, when distinguishing request types, the corresponding requests will be processed differently.

In ThinkPHP5, it is very simple to determine whether the current request is a POST request. Here are three methods to determine whether it is a POST request.

Method 1: Using the request object

In ThinkPHP5, you can obtain relevant information about the current request through the request object. By determining whether the current request method is POST, you can determine whether the current request is a POST request. The code is as follows:

use thinkRequest;

$request = Request::instance();
if ($request->isPost()) {
    // 处理POST请求的逻辑代码
}

In the above code, the Request class is first instantiated and the current request information is obtained. Then call the isPost() method of the Request object to determine whether the current request method is POST. If it is a POST request, the relevant business logic is executed.

Method 2: Using the input object

In the ThinkPHP5 controller, you can obtain relevant information about the current request through the input object. By judging whether the current request method is POST, you can judge whether the current request is a POST request. The code is as follows:

use thinkController;

class Index extends Controller
{
    public function index()
    {
        $request = $this->request->param();
        if ($this->request->isPost()) {
            // 处理POST请求的逻辑代码
        }
    }
}

In the above code, the input object is also used to obtain the information of the current request. Through the isPost() method of the request object, you can also determine whether the current request is a POST request or another type of request.

Method 3: Use the request helper function

In ThinkPHP5, a simpler method is also provided to determine whether the current request is a POST request. You can use the request helper function, the code is as follows:

if (request()->isPost()) {
    // 处理POST请求的逻辑代码
}

In the above code, obtain the current request information by calling the request() method, and directly use the isPost() method of the request() function to determine the current request Whether it is a POST request.

Whether you use the request object, input object or request helper function, you can easily determine whether the current request is a POST request. During the development process, you can choose to use different methods according to specific needs.
