AJAX 开机自检到服务器会导致错误 413:请求实体太大

Question

在JS插件中，我的Django视图接受base64编码图像的AJAXPOST。问题是图像太大。我收到以下错误。

django_1    | Traceback (most recent call last):
django_1    |   File "/usr/local/lib/python3.6/site-packages/raven/transport/threaded.py", line 165, in send_sync

关于如何解决这个问题的任何想法？我已经找到了nginx的解决方案，但是我正在cookiecutter-django项目中使用gunicorn。

免责声明：我强烈建议将 Nginx 服务器配置为代理传递给 Gunicorn...

看来nginx的client_max_body_size参数可能设置了两个低，以便将处理后的图像毫无问题地发布到服务器。我讨厌服务器配置，但您需要nginx配置进行编辑。感觉可以通过在nginx配置中的http{..}块中添加以下行来轻松解决：

http {
#...
client_max_body_size 100m;
client_body_timeout 1000s;
#...
} 

这甚至可能在您站点的nginx配置文件的服务器块中 -yoursite_nginx.conf：

server {
# the port your site will be served on
listen      8000;
# the domain name it will serve for
server_name example.com; # substitute your machine's IP address or FQDN
charset     utf-8;
# max upload size
client_max_body_size 100M;   # adjust to taste
# max timeout duration
client_body_timeout 1000s;  # adjust to taste
# Django media
location /media  {
alias /path/to/your/mysite/media;  # your Django project's media files - amend as required
}
location /static {
alias /path/to/your/mysite/static; # your Django project's static files - amend as required
}
# Finally, send all non-media requests to the Django server.
location / {
uwsgi_pass  django;
include     /path/to/your/mysite/uwsgi_params; # the uwsgi_params file you installed
}
}

请注意，您还需要在服务器上运行以下命令才能使更改生效：

$ service nginx reload

想通了。Django 的默认值对于 100mb+ 图像来说太低了。

不得不更改我的设置

DATA_UPLOAD_MAX_MEMORY_SIZE = XXXX
FILE_UPLOAD_MAX_MEMORY_SIZE = XXXX
