2. I navigated to the directory /webtv/wangjie/channel-pub-api/images/2020/08 and checked its permissions. I found that the user and group for the 26 directory were root. Because the program was upgraded today, the user and group that generate the directory have changed. I decided to delete the 26 directory and regenerate it via the API. The error no longer occurred, as shown in Figure 2.

3. Conclusion: If the 26 directory is created by the root user from the command line, an error will occur when the nginx user writes files to it via the API. If the 26 directory is created by the nginx user via the API, no error will occur when the nginx user writes files to it via the API. I recommend writing files using the root user from the command line. This ensures that both directory creation and file writing are performed by the root user.
