Recently, I often see the slogan of a plastic advertisement "Be beautiful, be safe". When I think of today's personal visa free payment system, my slogan should be "collect money, be safe".
With the popularity of the Internet We Media and various personal website applets, the payment system has played an important role in the online media. Our common payment methods are WeChat, Alipay, and bank cards, which account for a relatively large proportion of online vx scanning and Alipay scanning, while formal access and application channels, The website operator is required to provide enterprise qualification and relevant procedures to apply for Alipay and WeChat merchant platforms. As for access technology, it is also a headache for everyone. In this case, Alipay WeChat Personal visa free system It was sought after by the majority of grassroots webmasters.
So, what technical problems need to be solved to enable individual users to connect to the website for collection like the merchant interface? First of all, prepare your own collection code (this is nonsense). The most important thing is to have a software or APP that can notify your collection information to your website and complete the callback. If you can timely and accurately transmit the collection content to the target website, then the basic closedown will be completed.
We have studied most of the visa free systems on the market. In combination with the technical bottleneck, the most effective way of personal visa free callback is to obtain the notice on the notice bar of Alipay and WeChat via mobile phone for text comparison, check the amount, and return to the target website for callback. Then, the problem arises. At present, there are some unformed monitoring APPs, what kind of XP framework to use, and various ROOTs, which make the user experience very poor. In fact, the callback app only needs two or three important parameters. The first is the return address, which is your callback address. The second is the payment amount. The third is the payment type. Then there are other parameters, such as user name and order number. Recently, a set of monitoring APP was built, and three parameter positions were reserved, including callback address, key and communication security code. Also, a set was opened to encapsulate the callback address to the back end, and then the front end user filled in his user name on the platform by himself for monitoring. In this way, the callback parameters in the past include the amount, user name, and payment type, These three parameters basically meet the requirements of the target website to judge the payment results. No matter what kind of monitoring, the collection notice of Alipay and WeChat must be enabled to ensure that the notice can be received in the notice bar.
With this monitoring tool, let's extend it a bit. We can use this tool to build a visa free payment website for personal collection. Of course, it can also be developed into a multi-user website. Today, let's talk about the idea of ordering users. First, the function of the main program should be able to communicate with the monitoring APP, establish communication verification, upload Alipay and WeChat collection, add multiple websites for collection API collection callback, order statistical identification, supplement, view order details, etc.
If it is a one-to-one monitoring application, it is not very useful. This website needs to make a collection code available in every website I call. So the problem comes again. What if the amount is repeated in the same time period? In my humble opinion, only when an order is submitted, can we judge whether there is the same amount in this type of time period. If there is, we will increase or decrease the amount in a small amount on this basis and then return it to the client, so that the customer can pay the increased or decreased amount when paying.
Here, I also built a visa free payment website for individuals to use multiple websites based on the above ideas, which can dock API interfaces with multiple websites, and is simple and convenient. The background adds websites, generates keys, and the front client modifies keys and security codes, The APP monitoring end uses the scanning ma configuration. Alipay uses UID to generate code in real time without transmitting code, which can effectively prevent code blocking. However, WeChat only transmits code and pulls code, and all back-end programs are encapsulated. There is no clear text and clear transmission in the front end. The connection with DEMO is also well written. Compared with personal payment, the security is still average, and you can correct it more, If you need a reference, you can do the test or reference according to my demonstration.
