With the popularity of the Internet, the demand for Web development is also increasing. In Web development, API interfaces have become an indispensable part, and in the field of PHP, thinkphp5 is undoubtedly one of the most popular frameworks. This article will introduce how to use the thinkphp5 framework to write API interface requests and returns.

1. API interface request

1.1 GET request

In thinkphp5, it is very simple to use GET request to send API request. The following is a sample code:

use thinkRequest;

$request = Request::instance();

$name = $request->get('name');

$age = $request->get('age');

//做出響應(yīng)

In the above code, we use the instantiated object of the Request class, and then use the get method to obtain the request parameters. Next you can respond to the parameters.

1.2 POST request

In thinkphp5, the method of using POST request to send API request is basically the same as GET request. The following is a sample code:

use thinkRequest;

$request = Request::instance();

$name = $request->post('name');

$age = $request->post('age');

//做出響應(yīng)

In the above code, we also use the instantiated object of the Request class, and then use the post method to obtain the request parameters. Next you can respond to the parameters.

1.3 JSON request

In API development, JSON request is also a very common method. In addition to GET and POST requests, thinkphp5 also provides methods to accept and respond to JSON data. The following is a sample code:

use thinkRequest;

$request = Request::instance();

$data = $request->getContent();

$json = json_decode($data, true);

$name = $json['name'];

$age = $json['age'];

//做出響應(yīng)

In the above code, we first use the getContent method to obtain the JSON data in the request body, and then use json_decode to convert the JSON string into an array. Next operate or respond to the array.

2. API interface return

When developing an API interface, returning data is also very important. We usually need to return json data. The following is a sample code:

use thinkController;

class ApiController extends Controller {

    public function index() {

        //數(shù)據(jù)數(shù)組

        $result = [
            'code' => 0,
            'msg' => 'success',
            'data' => [
                'name' => 'test',
                'age' => 18
            ]
        ];

        //返回json數(shù)據(jù)

        return json($result);

    }

}

In the above code, we first define the array of returned data, and then use the json function to convert the array into a json string and return it.

3. Summary

In this article, we introduced how to use the thinkphp5 framework to write API interface requests and responses. In actual development, we also need to pay attention to issues such as the security and data format of interface requests. I hope this article can be helpful to readers and provide some help for everyone's API development.
