Preface
During the epidemic, I had nothing to do, and then I took a small program, the most common mall category. I have done a few small programs before, and other colleagues are responsible for the preliminary work and materials. I just developed it only, and thought it would not be very troublesome. Then this time I started from scratch and found that the preparation work such as reviewing and filling in information takes more effort than development. Everyone used for back-end management is open source and finished quickly. The applet finds a small template, and changes the interface and interface as needed. It is also very fast to finish, so most of the time is spent on preparations, so record this time .
1. Apply for WeChat to apply for platform account
For details log on micro-channel public platform , steps can refer to the documentation . This step is relatively simple, of course, can be registered only small program can also register the public association of small numbers and then apply for the program documentation .
2. Merchant certification
You can ignore this step for simple display mini programs or mini programs that do not involve payment. There is no way for merchants without authentication, and payment cannot be initiated without information such as merchant numbers.
materials needed:
1. Business license
2. Public account
3. Official WeChat certification application letter (page download, stamp and signature and date)
4. Public account receipt certificate
Three, the server
Choose the server according to your own needs, and then build various environments.
Four, server domain name
Requirements: 1. For the specific requirements of the https protocol, check the WeChat document , and then parse it to the server to apply for a certificate. I applied for a free certificate in Alibaba Cloud.
2. Filing, if you have a well-filed domain name so fast, you need to review your own filing, the long time is one month or one week, because I am in a hurry to use my friend’s domain name, and at the same time I apply for it on Alibaba Cloud For sign
At this time, the development preparation is almost complete.
