Convenient payment payment (2) - Convenient, Payment, two

In the previous article, I talked about generating a QR code for payment. The next step is WeChat payment. The program is almost written, just run with the merchant number to be tested by Weifutong. They gave it, but it didn’t work. I was puzzled. Later, I asked them in detail whether the WeChat Wap channel was still available. They said that the WeChat official had closed the payment channel permission for pure mobile browsers. At that time, I wanted to close it. Why Wei Fortis officially displayed the WeChat Wap document. What should I do? . . If this doesn’t work, change the course. You can also get the Openid of the user you want by authorization. Then study it again. The prerequisite for authorization is that the WeChat public account appid and secret development password must be required. With this, everything is easy to do, hahahaha share picture

General process:

Scan the code to display the individual merchant login page, enter the account password, enter the main page, the upper column displays the account number + individual merchant name, click on personal information to see the detailed information. Pending payment records, self-service payment, payment records. The key point is to talk about the records to be paid. The WeChat used here is scanned and entered, so only the WeChat payment channel is displayed. (Judging whether it is a WeChat browser or an Alipay browser can be distinguished)

So you can get it. Tell the customer that you need them They don’t provide the WeChat official account. It’s a bumpy road. It’s more like a bank. If you don’t give it, it’s understandable. But if you don’t give it to me, you won’t let the payment succeed. I finally negotiated and let me go. I asked them to return me a user Openid. I said that I still do so many things, so I can still learn something. 1. Check the order before payment 2. WeChat payment must have parameters
