Question

我目前正在为我的网站创建一个api，使用nodejs和nginx，我为每个nodejs app设置了反向代理我将运行（api，mainsite，其他东西......）

但是，当我尝试使用api时，它会在每次请求时使用很长时间，有时会超时...

任何想法都错了吗？它已经有一段时间了，它杀了我:(

请帮忙，这会浪费我开发应用的时间：/

Answer 1

添加此内容是因为这对我有用

https://forum.nginx.org/read.php?15,239760,239760似乎表明您可以proxy_pass到127.0.0.1而不是localhost，并且请求可以顺利通过

macbresch

一岁，但我想指出，该问题可以解决。就像Cruz Fernandez所写的那样，您可以在proxy_pass指令上设置127.0.0.1而不是localhost。这样可以防止每秒钟请求延迟60秒。我正在使用Windows 8.1和nginx 1.9.5。

Cruz Fernandez写：

您可以使用127.0.0.1（而不是proxy_pass指令上的localhost）

location /nodejsServer/ {
    proxy_pass http://127.0.0.1:3000/;
}

Answer 2

我能够通过使用上游语句来解决这个问题。

例如。：

TextField field = new TextField(writer, new Rectangle(x, y - h, x + w, y), name);
field.BackgroundColor = new BaseColor(bgcolor[0], bgcolor[1], bgcolor[2]);
field.BorderColor = new BaseColor(
    bordercolor[0], bordercolor[1], bordercolor[2]);
field.BorderWidth = border;
field.BorderStyle = PdfBorderDictionary.STYLE_SOLID;
field.Text = text;
writer.AddAnnotation(field.GetTextField());

参考：http://nginx.org/en/docs/http/ngx_http_upstream_module.html

nginx每秒请求都会变慢
