加载大文件时，Chrome上的nginx和代理服务器上的ERR_CONTENT_LENGTH_MISMATCH [英] ERR_CONTENT_LENGTH_MISMATCH on nginx and proxy on Chrome when loading large files

问题描述

  GET http：// localhost / grunt / vendor / angular / angular.js net :: ERR_CONTENT_LENGTH_MISMATCH 
  

只有当同时发生的请求朝向nginx时才会发生，例如当浏览器缓存为空并且整个应用程序加载时。

以下是从Chrome浏览器复制的这些请求的标题：

 远程地址：127.0.0.1：80

文件的真实大小：

  $ ll vendor / angular / angular.js 
 -rw-rw-r-- 1 xxxx staff 873444 Aug 30 07:21 vendor / angular / angular .js 
  

您可以看到 Content-Length 和文件的实际大小是一样的，所以这很奇怪。

以及此代理的nginx配置：

  location / grunt / {
 proxy_pass http：// localhost：9000 /; 
 
 $ / code> 

任何想法？



感谢



编辑：在错误日志中找到更多信息：

angular.js 并且不能由于权限问题。下面是解决这个问题的方法：

$ $ $ $ $ $ $ $ $ c $ root $ amac-2 / usr / local / var / run / nginx $ chown -R _www：admin proxy_temp

_www：admin might在你的情况下不同，取决于哪个用户拥有nginx进程。查看更多有关ServerFault的信息：

I'm getting the following error on my chrome console:

GET http://localhost/grunt/vendor/angular/angular.js net::ERR_CONTENT_LENGTH_MISMATCH 

This only happens when a simultaneous requests are shot towards nginx e.g. when the browsers cache is empty and the whole app loads. Loading the resource above as a single requests succeeds.

Here are the headers to this requests, copied from Chrome:

Remote Address:127.0.0.1:80

the real size of the file:

$ ll vendor/angular/angular.js
-rw-rw-r--  1 xxxx  staff  873444 Aug 30 07:21 vendor/angular/angular.js

As you can see Content-Length and the real size of the file are the same, so that's weird

And the nginx configuration to this proxy:

location /grunt/ {
    proxy_pass  http://localhost:9000/;
}

Any ideas?

Thanks

EDIT: found more info on the error log:

2014/09/23 13:08:19 [crit] 15435#0: *8 open() "/usr/local/var/run/nginx/proxy_temp/1/00/0000000001" failed (13: Permission denied) while reading upstream, client: 127.0.0.1, server: localhost, request: "GET /grunt/vendor/angular/angular.js HTTP/1.1", upstream: "http://127.0.0.1:9000/vendor/angular/angular.js", host: "localhost", referrer: "http://localhost/grunt/"

解决方案

It seems that under pressure, nginx tried to pull angular.js from its cache and couldn't due to permission issues. Here's what solved this issue:

root@amac-2:/usr/local/var/run/nginx $ chown -R _www:admin proxy_temp

_www:admin might be different in your case, depending which user owns the nginx process. See more information on ServerFault:
