Recently, we are docking with the face recognition of the public security. Of course, we are also docking through a third party. After the system is online, various errors are reported, including empty parameters and no permissions. In the process of troubleshooting, it was found that the failed screens were all horizontal. But there is no evidence to prove that all horizontal screens have problems. This problem has been tangled for a long time. Finally, I thought of a very simple way to remember the same picture, adjust the interface once in the vertical screen, and then adjust the interface again in the horizontal screen. If the vertical screen can be crossed, but the horizontal screen fails, 80~90% is because of the horizontal screen. Call the interface directly and find that there is a problem with the horizontal screen (rotation of the vertical screen by 90 degrees), and there is no problem with the vertical screen.
If you can figure it out, it's actually very simple, but I really struggled for a long time before thinking about it. Sometimes it's dark under the lights, and there is the easiest way, but you have to look for it in various ways. This reminds me of the story of the doctoral student who spent 1 million to verify whether the soap box was empty, and the migrant workers solved the problem with two high-powered fans.
Record the bit of work, it is a bit of accumulation.
