[英]Http request timeout at 2 minutes in NGINX 502 bad gateway in Node app
I'm been scratching my head on this timeout issue and hope to get some helps. 我一直在抓住这个超时问题并希望得到一些帮助。 I have a http request that might take 2.5 minutes to return the response. 我有一个http请求可能需要2.5分钟才能返回响应。 I have timeout handling in Angular for 3 minutes, and NodeJS for 3 minutes as well. 我在Angular中处理超时处理3分钟,NodeJS处理3分钟。 My nginx setting have 200 seconds timeout and my Elastic Load Balancing Connection Timeout is set to 4 minutes. 我的nginx设置有200秒超时,我的Elastic Load Balancing连接超时设置为4分钟。 However, I keep seeing the 502 bad gateway nginx 1.4.6 (Ubuntu) error at exact 2 minutes. 但是,我一直在2分钟内看到502坏网关nginx 1.4.6(Ubuntu)错误。 Is there any part that I miss to have longer timeout? 有没有我错过超时的部分?
My nginx setting: 我的nginx设置:
server {
listen 80;
server_name;
access_log /var/log/nginx/access.log;
error_log /var/log/nginx/error.log debug;
location / {
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header Host $http_host;
proxy_set_header X-NginX-Proxy true;

My NodeJS setting is using connect-timeout 我的NodeJS设置正在使用connect-timeout
var timeout = require('connect-timeout');
app.use(timeout(300000));
I just came across this today, and probably found an answer - there is 120 s hard coded timeout in node's http
module. 我今天刚刚遇到这个问题,并且可能找到了答案 - 节点的http
模块中有120秒的硬编码超时。 I had to set socket timeout in given request handler like this: 我不得不在给定的请求处理程序中设置socket超时,如下所示:
yourHandler(req, res) {
req.socket.setTimeout(3600e3); // 1 hour
// ... do the real work
res.json(...);
}
You can also set this limit to 0
to disable this timeout. 您也可以将此限制设置为0
以禁用此超时。
