Nginx is a high performance open source web server and reverse proxy server. It can be used to process HTTP requests and responses, and provides functions such as static file serving, load balancing, reverse proxy, and caching. The following principles and explanations may be involved in the situation that sometimes succeeds and sometimes fails when uploading PDF files:
- Client request: The client uploads the PDF file to the Nginx server through an HTTP request. Requests may contain file data and other relevant information such as filename, size, etc.
- Nginx configuration: There may be related configuration items in the Nginx configuration file, for example
client_max_body_size, to limit the size of uploaded files. If the size of the uploaded file exceeds this limit, the upload may fail. - File processing: After receiving the uploaded file, Nginx may process the file, such as verifying, storing, renaming, etc. Errors or exceptions may have occurred during processing, causing the upload to fail.
- Server resources: Uploading large files may consume more server resources, such as memory and disk space. If the server resources are insufficient, the upload may fail or be limited.
