R Plumber API:防止"504网关超时“
R Plumber API:防止"504网关超时“
提问于 2017-06-19 19:02:14
我已经使用plumber编写了一个have，并将其部署到instructions中的数字海洋水滴。
我在.json数据中发布，并期待.json数据返回。为此，我从命令行使用curl命令，例如：
curl --data @data/data.json http://[API ADDRESS] > results/output.json当我发布一个小的数据集时，这很好用，但随着数据集变得更大，我开始收到如下的HTTP错误：
<html>
<head><title>504 Gateway Time-out</title></head>
<body bgcolor="white">
<center><h1>504 Gateway Time-out</h1></center>
<hr><center>nginx/1.10.0 (Ubuntu)</center>
</body>
</html>我试着编辑/etc/nginx/nginx.conf，以允许更长的超时和更大的文件，但仍然没有成功。nginx.conf文件如下所示：
user www-data;
worker_processes auto;
pid /run/nginx.pid;
events {
worker_connections 768;
# multi_accept on;
}
http {
##
# Basic Settings
##
sendfile on;
tcp_nopush on;
tcp_nodelay on;
keepalive_timeout 3000;
types_hash_max_size 2048;
# server_tokens off;
##
# Allow for longer jobs
##
client_header_timeout 3000;
client_body_timeout 3000;
fastcgi_read_timeout 3000;
client_max_body_size 100M;
fastcgi_buffers 8 128k;
fastcgi_buffer_size 128k;
# server_names_hash_bucket_size 64;
# server_name_in_redirect off;
include /etc/nginx/mime.types;
default_type application/octet-stream;
##
# SSL Settings
##
ssl_protocols TLSv1 TLSv1.1 TLSv1.2; # Dropping SSLv3, ref: POODLE
ssl_prefer_server_ciphers on;
##
# Logging Settings
##
access_log /var/log/nginx/access.log;
error_log /var/log/nginx/error.log;
##
# Gzip Settings
##
gzip on;
gzip_disable "msie6";
# gzip_vary on;
# gzip_proxied any;
# gzip_comp_level 6;
# gzip_buffers 16 8k;
# gzip_http_version 1.1;
# gzip_types text/plain text/css application/json application/javascript text/xml application/xml application/xml+rss text/javascript;
##
# Virtual Host Configs
##
include /etc/nginx/conf.d/*.conf;
include /etc/nginx/sites-enabled/*;
}然后我用sudo service nginx restart重新启动了nginx服务器，但仍然收到超时错误。
/var/log/nginx/error.log行如下所示：
*4 upstream timed out (110: Connection timed out) while reading response header from upstream, client: [MY IP], server: _, request: "POST [API]", upstream: "http://127.0.0.1:8000/[API]", host: "[HOST ADDRESS]"任何关于水管工如何在引擎盖下工作的帮助或提示都是非常有用的。非常感谢！
