微信小程序为什么要放置校验文件？Why should the WeChat applet place the verification file?
微信小程序为什么要放置校验文件？社区的开发者朋友以及微信团队:
你们好！
我有一些问题请教一下：
背景: 本人负责公司 “用户登录和身份验证系统CIAM” 在中国的部分工作，并不直接负责小程序开发。但是很多的小程序开发团队会找到我，要求我放置小程序域名校验文件。由于我负责的这个CIAM系统是工作业务的基础，几乎所有和终端用户相关的系统都要通过跳转到这个用户登录和身份验证系统CIAM来完成用户登录和身份识别，我们这个系统就要收到放置各种小程序域名校验文件的要求。这些域名校验文件对应小程序的放置和信息维护是个要长期考虑的问题。
问题：
谢谢大家！
Community developer friends and wechat team: Hello! I have some questions to ask: BACKGROUND: I am responsible for part of the company's "user login and authentication system CIAM" in China, and I am not directly responsible for small program development. However, many applet development teams will find me and ask me to place the applet domain name verification file. Since the CIAM system I am responsible for is the basis of business, almost all systems related to end users need to complete user login and identification by jumping to the user login and authentication system CIAM. Our system needs to receive the requirements for placing various small program domain name verification files. The placement and information maintenance of these domain name verification files corresponding to small programs should be considered for a long time. Question: what is the reason for releasing the applet domain name verification file? Do you want to place the applet domain name verification file? (the environment is officially launched, and it can not be verified before it is launched.) the verification of applet domain name seems to be a unique demand in China. Our user login and authentication system CIAM is a global common system, and CIAM system is generally not customized. Can I avoid placing applet domain name verification files? If the answer to the above question is no, can Tencent come up with relevant schemes for our basic underlying services to allow many applets to place only one unified verification file, so as to avoid the maintenance of multiple verification files and related information? Thank you!

Welcome to China
1.放置校验文件一般是小程序内需要通过web-view访问的域名进行所有权校验。
2.验证通过后可以随时删除校验文件。
3.这个是小程序的规定，和国家无关。

1，他们微信官方不能让开发者随意设置域名，需证明开发者对该域名有权限（用放置校验文件来证明）。
2，3，4，可参考1的答案。
