uwsgi + nginx + flask: upstream prematurely closed

flask

我在烧瓶上创建了一个端点,该端点从数据库查询(远程数据库)生成电子表格,然后将其作为下载内容发送到浏览器中。Flask不会抛出任何错误。Uwsgi没有抱怨。

但是当我检查nginx的error.log时,我看到了很多

2014/12/10 05:06:24 [错误] 14084#0:* 239436上游过早关闭连接,同时从上游读取响应头,客户端:34.34.34.34,服务器:me.com,请求:“ GET / download / export .csv HTTP / 1.1”,上游:“ uwsgi://0.0.0.0:5002”,主机:“ me.com”,引荐来源网址:“ https://me.com/download/export.csv

我像部署uwsgi

uwsgi --socket 0.0.0.0:5002 --buffer-size=32768 --module server --callab app

我的nginx配置:

server {
     listen 80;
     merge_slashes off;
     server_name me.com www.me.cpm;

     location / { try_files $uri @app; }
       location @app {
          include uwsgi_params;
          uwsgi_pass 0.0.0.0:5002;
          uwsgi_buffer_size 32k;
          uwsgi_buffers 8 32k;
          uwsgi_busy_buffers_size 32k;
     }

}

server {
      listen 443;
      merge_slashes off;
      server_name me.com www.me.com;

    location / { try_files $uri @app; }
       location @app {
          include uwsgi_params;
          uwsgi_pass 0.0.0.0:5002;
          uwsgi_buffer_size 32k;
          uwsgi_buffers 8 32k;
          uwsgi_busy_buffers_size 32k;
       }
}

这是nginx或uwsgi问题,还是两者都有?

更改nginx.conf以包括

sendfile        on;
client_max_body_size 20M;
keepalive_timeout  0;
