php WeChat public account js-sdk development application-PHP Tutorial-php.cn

This article mainly introduces the relevant information of PHP WeChat official account js-sdk development and application in detail. It has certain reference value. Interested friends can refer to

test js interface. Function, I am using BAE server not SAE server. The SAE server cannot write files and there will be problems with the test.
What is js-sdk, let me first demonstrate the specific function of the js-sdk interface.

I randomly open a push article on WeChat as shown below:

php WeChat public account js-sdk development application

Click on the first article

The above is our connection article. If we send this article to a friend, the display effect will be as follows:

php WeChat public account js-sdk development application

Share to Moments and let’s see the effect:

Why is it also an article link, in the official account, sent to friends, The interface effect displayed when sending to Moments is different. The display effect of the official account is because the WeChat official account calls the WeChat message interface when pushing, and the latter two are because the page calls the SDK interface related to js-sdk.
Send to friends calls the js interface to obtain the click status of the "Share to friends" button and the custom sharing content interface.
Send to Moments calls the js interface to obtain the click status of the "Share to Moments" button and the custom sharing content interface.

Let’s implement the steps to call the js-sdk interface:

Step one: Enter the "Function Settings" of the "Public Account Settings" on the WeChat public platform and fill in the "JS interface security domain name".

As shown below:

Only pages placed under this domain name can call the js interface.

Second step: http://demo.open.weixin.qq.com/jssdk/sample.zip Connect to this address to download, open the php folder inside, You found 4 php files

The first 3 php files are configuration files, don’t touch them, sample.php is what we opened in WeChat Connection page, in this page we write our page code. I used this file for testing, and the code inside is different from the original version.

<?php
// echo "nihao";
require_once "jssdk.php";
$jssdk = new JSSDK("wxaf471be5d2bc9521", "93f5c3817074d43e7a7ab3f403cc72dd");//JSSDK中的参数是appid和appsecret。
$signPackage = $jssdk->GetSignPackage();//获取配置参数。
?>

To test the interface function of js, I am using the BAE server, not the SAE server. The SAE server cannot write files and there will be problems with the test.
