How to connect uniapp to thinkphp

With the advent of the mobile Internet era, mobile APPs have gradually become an indispensable part of people’s lives. In order to meet market demand and improve user experience, many companies and developers have begun to choose to use uniapp (cross-terminal development framework) to develop their own apps. For back-end development, thinkphp is an excellent open source framework in the PHP language. So the question is, how to use thinkphp for interface development in uniapp? Below, this article will introduce in detail how to use uniapp to connect to the thinkphp framework.

1. Prerequisite knowledge

Before reading this article, you should have mastered the basic knowledge of uniapp, the difference between uniapp and vue, as well as the basic knowledge of PHP and thinkphp. If you haven’t already, it’s recommended to learn these basics first.

2. Backend environment configuration

Before starting to connect to thinkphp, we need to set up a local PHP environment and install the thinkphp framework in it. If not, you can refer to the following steps:

1. Download the PHP environment package (such as WAMP, XAMPP or LAMP)
2. Install the PHP environment package.
3. Download thinkphp framework.
4. Unzip the thinkphp framework into the server directory.
5. Start the server.
6. Visit http://localhost/thinkphp in the browser to determine whether the installation is successful.

3. Connect to thinkphp

To connect to thinkphp in uniapp, you can use the built-in network request library that comes with uni-app. You can use the uni.request method to make network requests. The following is a simple example:

uni.request({
    url: 'http://localhost/thinkphp/public/index.php',
    data: {
        name: 'foo',
        age: 20
    },
    success: function (res) {
        console.log(res.data);
    }
});

In this example, we send an HTTP GET request to the local thinkphp installation directory. The request parameter is a JSON object, which contains the values ​​​​of the two attributes name and age.

4. Server-side development

Finally, we need to receive the request and return the response through thinkphp on the server side. The following is a simple example:

<?php
// 接收 GET 请求
$name = $_GET[&#39;name&#39;];
$age = $_GET[&#39;age&#39;];

// 构造返回 JSON 数据
$data = array(
    &#39;name&#39; => $name,
    'age' => $age,
);
$json = json_encode($data);

// 返回 JSON 数据
echo $json;
?>

In this example, we use $_GET to receive the GET request and construct a JSON object containing the name and age values, and then encode it through the json_encode function Return in JSON format.

Summary:

The above code is just a simple request and response example. In actual development, more parameters may need to be received, and more complex logic may be required to process the request. But in general, this is the basic process for connecting uniapp to thinkphp. At the same time, it should be noted that cross-domain issues need to be resolved during the joint debugging process. Because uniapp uses the Hbuilder The following code can be added to the thinkphp configuration file:

header("Access-Control-Allow-Origin: *");
header("Access-Control-Allow-Headers: Origin, X-Requested-With, Content-Type, Accept");

The above is a simple example of uniapp accessing the thinkphp framework. It can provide an idea, and interested readers can perform practical operations accordingly.
