How to deal with it

1. First of all, we need to go to the development management of the WeChat public platform --> development settings, find (scan the QR code of the common link to open the applet), click Add, and the following page will appear. After configuration, click Save

Fill in the page configuration and click save to publish

2. Receive parameters on the page to be redirected in the WeChat applet, in the onLoad method

onLoad((option) => {
    
    
	console.log(option)
	
	if(option.q&&option.q!="undefined"){
    
    
		// 获取到二维码原始链接内容
		const qrUrl = decodeURIComponent(option.q) 
		console.log(qrUrl);
		//此处就是我们要获取的参数 json
			
	}				
});

3. Scan the QR code to jump to the Mini Program page (the domain name path returned by the QR code must be the same as the one set in the WeChat official page)
