Upload size control
client_max_body_size
Set the maximum client request size
The default size is 1M, which can be used in http, server, location blocks.
Set different size controls according to different request paths
server {
listen 9001;
client_max_body_size 2M;
location / {
root D:\\server\\nginx-1.22.0\\html\\9001;
}
location /upload/large {
# Set a 50MB limit for large file upload paths client_max_body_size 50M;
}
location /upload/small {
# Set a 10MB limit for small file upload path client_max_body_size 10M;
}
}
Download control
Download speed control
limit_rate $rate
Limit file download speed, the default value is limit_rate 0; no download speed control is performed. $rate is used to specify the amount of data that can be downloaded per second.
The scope of the limit_rate directive can be http, server, location, if in location.
Restrict file downloads
server {
listen 9001;
limit_rate 100k;
location / {
root html;
}
}
Downloading files under this server will limit the download speed to 100kb per second.
limit_rate_after
The limit_rate_after instruction can set the limit download speed after a certain amount of data is transferred. It is usually used to limit subsequent download speeds when a file has started downloading.
location /download {
root html;
limit_rate_after 2M;
limit_rate 100k;
}
The above configuration is to start speed limit after 2M download, which is 100kb per second.
Control download speed in different conditions
If you want to control the download speed based on different conditions (such as the requested file type, client IP, or the requested file size, etc.), you can combine map instructions and limit_rate to implement more complex logic.
http {
map $http_user_agent $download_speed {
default 100k; # Default speed limit 100KB/s ~*Chrome 300k; # For Chrome browser, download speed limit is 300KB/s ~*Firefox 200k; # For Firefox browsers, download speed limit is 200KB/s }
server {
listen 9001;
location /donload/ {
# Dynamically set download speed using map limit_rate $download_speed;
root html;
}
}
