我很难用Flask-Restplus部署Flask应用程序。
中本地工作（wezkrug）时，一切都很有效但是当我使用nginx + uwgsi在我的应用程序中部署我的应用程序时，在访问http://example.com/api时，我继续从服务器获得404响应...
看起来Flask-Restplus正在使用swaggerui进行Swagger ...我是否必须在nginx.conf中添加一些东西才能提供这个服务？请原谅我的无知，但我以前没有使用过nginx的经验
这是我声明包含API
的蓝图的方式# Configure the Blueprint for API
blueprint = Blueprint('api', __name__, url_prefix='/api')
api.init_app(blueprint)
api.add_namespace(programs_namespace)
api.add_namespace(students_namespace)
app.register_blueprint(blueprint)
这是我在/etc/ngingx/conf.d/mysite.conf上的nginx配置
server {
listen 80;
server_name _;
client_max_body_size 400M;
location / {
auth_basic "Restricted";
auth_basic_user_file htpasswd;
try_files $uri @app;
}
location /static/ {
root /home/mysite/mysite/portal/src/portal;
access_log off;
error_page 404 = @app;
expires 7d;
}
location @app {
include uwsgi_params;
uwsgi_pass 127.0.0.1:5000;
access_log /var/log/nginx/mysite_access.log main;
error_log /var/log/nginx/mysite_error.log warn;
}
}
# SSL Server
server {
listen 443 default_server ssl;
client_max_body_size 400M;
ssl_certificate /etc/nginx/conf.d/mysite.crt;
ssl_certificate_key /etc/nginx/conf.d/mysite.key;
ssl_protocols SSLv2 SSLv3 TLSv1;
ssl_ciphers ALL:!ADH:!EXPORT56:RC4+RSA:+HIGH:+MEDIUM:+LOW:+SSLv2:+EXP;
ssl_prefer_server_ciphers on;
keepalive_timeout 70;
location / {
auth_basic "Restricted";
auth_basic_user_file htpasswd;
try_files $uri @app;
}
location /static/ {
root /home/mysite/mysite/portal/src/portal;
access_log off;
error_page 404 = @app;
expires 7d;
}
location @app {
include uwsgi_params;
uwsgi_pass 127.0.0.1:5000;
access_log /var/log/nginx/mysite_access.log main;
error_log /var/log/nginx/mysite_error.log warn;
}
}
我必须说当我尝试访问http://example.com/api时，根本没有输出日志文件。
应用程序使用uwgsi通过init脚本运行，您可以在此处查看内容：
mysite_dir=${mysite_DIR-/home/mysite/mysite/portal/src/portal}
pidfile=${PIDFILE-/var/run/mysite/mysite.pid}
uwsgi_bin=/usr/local/bin/uwsgi
uwsgi_url=127.0.0.1:5000
uwsgi_app=uwsgiapp
uwsgi_parameters="-p 4 -M -t 300"
logfile=${LOGFILE-/var/log/mysite.log}
user=mysite
chk_pidfolder() {
[ -d "${pidfile%/*}" ] || install -o $user -g $user -d "${pidfile%/*}"
}
start() {
log_daemon_msg "Starting mysite"
start-stop-daemon --start -c $user -g $user --pidfile $pidfile --exec $uwsgi_bin -- --chdir $mysite_dir --pidfile $pidfile -s $uwsgi_url -w $uwsgi_app $uwsgi_parameters -d $logfile --callable app --enable-threads --post-buffering 4096
log_end_msg $?
}
stop () {
log_daemon_msg "Stopping mysite"
if [ -e "$pidfile" ]; then
pid=`cat "$pidfile"`
else
pid=`pidofproc $uwsgi_bin`
fi
kill $pid
stopped=false
for ((i=0; i<10; i++)); do
if [ -d /proc/$pid ]; then
printf "."
sleep 2
else
stopped=true
break
fi
done
if $stopped ; then
rm -f $pidfile
log_end_msg 0
else
kill -6 $pid
log_warning_msg "no success, attempted to kill the process with -6, manual check recommended"
fi
}
case "$1" in
start)
chk_pidfolder
start
;;
stop)
stop
;;
status)
log_daemon_msg "Status of mysite"
status_of_proc -p $pidfile $uwsgi_bin mysite
# if [ $? -eq 0 ]; then
# log_end_msg 0
# exit 0
# else
# log_end_msg 1
# exit 1
# fi
;;
restart)
log_daemon_msg "Restarting mysite"
stop
sleep 4
start
;;
*)
echo $"Usage: $prog {start|stop|restart}"
exit 2
;;
esac
exit 0
谢谢！

正如Flask's documentation中所述，您可能希望对您的nginx配置使用ProxyFix +一些修改。
在您的应用程序代码中，您可能希望执行以下操作：
# Configure the Blueprint for API
blueprint = Blueprint('api', __name__, url_prefix='/api')
api.init_app(blueprint)
api.add_namespace(programs_namespace)
api.add_namespace(students_namespace)
app.register_blueprint(blueprint)
# Here we patch the application
from werkzeug.contrib.fixers import ProxyFix
app.wsgi_app = ProxyFix(app.wsgi_app)
然后你的nginx配置必须看：
server {
listen 80;
server_name _;
client_max_body_size 400M;
location / {
auth_basic "Restricted";
auth_basic_user_file htpasswd;
try_files $uri @app;
}
location /static/ {
root /home/mysite/mysite/portal/src/portal;
access_log off;
error_page 404 = @app;
expires 7d;
}
location @app {
include uwsgi_params;
proxy_set_header Host $host;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header X-Forwarded-Proto $scheme;
uwsgi_pass 127.0.0.1:5000;
access_log /var/log/nginx/mysite_access.log main;
error_log /var/log/nginx/mysite_error.log warn;
}
}
# SSL Server
server {
listen 443 default_server ssl;
client_max_body_size 400M;
ssl_certificate /etc/nginx/conf.d/mysite.crt;
ssl_certificate_key /etc/nginx/conf.d/mysite.key;
ssl_protocols SSLv2 SSLv3 TLSv1;
ssl_ciphers ALL:!ADH:!EXPORT56:RC4+RSA:+HIGH:+MEDIUM:+LOW:+SSLv2:+EXP;
ssl_prefer_server_ciphers on;
keepalive_timeout 70;
location / {
auth_basic "Restricted";
auth_basic_user_file htpasswd;
try_files $uri @app;
}
location /static/ {
root /home/mysite/mysite/portal/src/portal;
access_log off;
error_page 404 = @app;
expires 7d;
}
location @app {
include uwsgi_params;
proxy_set_header Host $host;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header X-Forwarded-Proto $scheme;
uwsgi_pass 127.0.0.1:5000;
access_log /var/log/nginx/mysite_access.log main;
error_log /var/log/nginx/mysite_error.log warn;
}
}
