Question

我正在开发一个带有laravel后端的ember.js应用程序。如果出现问题，我正试图用php返回http错误代码。我注意到，当发出PUT请求并返回400状态代码时，我的conf文件会被我的conf文件忽略，这会破坏我的前端。我不知道为什么PUT / 400代码组合让nginx忽略我的conf。任何帮助将非常感激。

 server {
  listen                *:80 ;

  server_name           userchamp.com;
  access_log            /var/log/nginx/embertest.com.access.log;

  location / {

    root  /var/www/embertest/public;
    try_files  $uri  $uri/  /index.php?$args ;
    index  index.html index.htm index.php;

  }

  location ~ \.php$ {

Answer 1

对于nginx＆gt; = 1.7.5

在标题定义中附加“always”：

add_header 'Access-Control-Allow-Origin' '*' always;

对于nginx＆lt; 1.7.5

根据ngx_header_module的nginx官方文档，add_header在响应代码为400时无法正常工作

syntax: add_header name value; default: — context: http, server, location, if in location Adds the specified field to a response header provided that the response code equals 200, 201, 204, 206, 301, 302, 303, 304, or 307. A value can contain variables.

另一方面，您可以尝试更强大的HttpHeadersMoreModule。

Answer 2

我认为@simon提供了正确答案：

如果您使用nginx＆gt; = 1.7.5，则可以添加名为“always”的第三个参数。

返回400个代码时，nginx添加标头
