How to use PHP to implement web page embedding technology in WeChat mini programs

With the rapid development of WeChat mini programs, more and more companies and developers have begun to pay attention to the development and use of WeChat mini programs. In the actual development process, we often encounter the need to embed web page content into small programs, which requires the use of web page embedding technology.

This article will introduce in detail how to use PHP to implement web page embedding technology in WeChat mini programs.

1. Introduction to webpage embedding technology in WeChat mini-programs

Webpage embedding technology in WeChat mini-programs refers to embedding webpage content into mini-programs so that users can directly Browse web content. In practical applications, many websites need to embed web content into mini programs to improve user experience and user stickiness.

There are two main methods of webpage embedding technology: one is to use the WebView component provided by the WeChat applet, that is, to display the webpage content through the WebView embedded in the applet; the other is to use the HTTP interface to display the webpage content in the applet. Web pages are embedded in the program's pages.

2. Use PHP to implement web page embedding technology in mini programs

1. Use the WebView component in mini programs

The WebView component is provided by WeChat mini programs A component used to display web pages, which can display web pages in mini programs.

Developers can use the web-view tag in the wxml file of the mini program page and add it to the page as a subcomponent. The specific code is as follows:

Among them, the src attribute specifies the The displayed web page address can be a complete URL link.

2. Embedding web pages through the HTTP interface in the mini program page

If developers want to embed web pages through the HTTP interface in the mini program page, they can do so by using PHP.

First, developers need to define an interface in the PHP code to obtain the web page content that needs to be embedded. The specific code is as follows:

header('Content-type:text/html;charset=utf-8');
$url = $_GET['url'];
$data = file_get_contents($url);
echo $data;
?>

Among them, $_GET['url'] represents the parameters passed through the GET request, which can be A complete URL link.

Next, introduce a WebView component into the mini program page, and call the interface defined by PHP by setting the src attribute of the component. The specific code is as follows:

Among them, webviewUrl is the one defined in the applet page Variable, used to store the URL link of the PHP interface.

3. Notes

1. When using the WebView component, you need to pay attention to controlling the size and position of the web page, otherwise the problem of incomplete web page display may occur.
2. When using the HTTP interface, you need to pay attention to security and cross-domain issues of the interface. Some security verification logic can be added to the PHP code.
3. When using PHP to implement web page embedding technology, you also need to pay attention to the compatibility of the PHP version and the optimization of the code to ensure the stability and performance of the code.

4. Summary

This article mainly introduces how to use PHP to implement web page embedding technology in WeChat mini programs, including two methods, one is to use the technology provided by WeChat mini programs WebView component, the other is to embed web pages in mini program pages through HTTP interface. Developers can choose the appropriate method according to specific needs and pay attention to relevant precautions.
