2. The redirect_uri parameter is wrong

Log in to the public management backend - click Developer Center - find the web account, click Modify, write your own domain name, save and take effect.

3. The page URL is not registered

The test authorization directory I set up is: http://www.xxx.com.cn/m/test/wxpay/example/
My JsApi payment page is: http://www.xxx.com.cn/m/test/wxpay/example/money.php

4. Sample page

jsapi.php jsApi payment
micropay.php Pay by credit card
native.php scan code to pay
orderquery.php order query
refund.php order refund
refundquery.php refund query
download.php download order<script>ec(2);</script>
