Today is November 14, 2020. Compared with the previous week, this week has a lot less sense of fulfillment, and I have not learned anything substantial.
Sandbox Alipay
I was in the group the night before. I was watching Vue's video, but suddenly I felt tired and wanted to fall asleep. After persisting for a while, there was no progress, and finally closed the vue video directly. Just when I had nothing to do and didn't know what to do next, I suddenly remembered the Alipay sandbox made on the back-end as a freshman, which seemed to make the balance on Alipay 999999.99, and my interest suddenly rose.
Before I knew that the back end was implemented by Alipay sandbox in java, I wondered if it could be implemented with node. Check out Baidu, by coincidence, the first blog is a demo. I followed the steps above and my spirits became more and more elevated. It was not until Alipay reminded me that my demo was suspected of phishing websites, which made me feel a little calm. Continue to Baidu, but has been unsuccessful.
Until the next day came to the group, started, failed! I got stuck thinking, why does Alipay remind me of the risk of phishing websites? Does it mean that there is a problem with my current network situation? I am currently using a campus network with a layer of proxy server in the middle. Could it be the problem of this proxy? Forget it, let's try the mobile hotspot...change the network...start, success!
PS: Later, I found that it was enough to change the browser, so the network proxy layer is not the main reason.
web performance
I bought a book "The Definitive Guide to Web Performance". I bought it on Pinduoduo for 20 yuan. Although I knew this book was pirated from the beginning, the level of piracy really exceeded mine after I bought it. Imagine, and I also met the customer service of the repeater for the first time . It really made me angry and laughed. I will put two pictures to give you your feelings:
