我如何配置django rest框架分页URL

Question

当我在django rest框架中获得一个对象时,url总是绝对地使用localhost,但是在生产中我通过nginx上的代理,有没有办法在设置中设置这个url

例

count: 11
next: "http://localhost:8000/api/accounts/?ordering=-date_registered&page=2"
previous: null

我需要它

count: 11
next: "http:/example.com/api/accounts/?ordering=-date_registered&page=2"
previous: null

请看我完整的nginx配置

server {
    listen 80;
    server_name 123.123.123.123;
    root            /home/admin/www/site-web/dist;
    index           index.html;

    location /static/ {

    location /nginx_status/ {
        # Turn on nginx stats

对不起伙计们,我有'underscores_in_headers on;' 我删除它,一切正常

听起来你的Host标题没有正确设置,这在你的nginx配置中会出现问题.问题是您Host发送的标头包含端口号,因此Django在构建URL时包含端口号.这将导致CSRF未来出现问题,因为CSRF检查在您不进行调试时会执行严格的端口检查.

众所周知,出于类似的原因会导致SSL出现问题.

您可以通过将HostNginx中的标头设置为不包括代理端口来解决此问题.

proxy_set_header Host $http_host;

请注意,我使用$http_host变量而不是$host或$host:$server_port.这将确保Django仍然会在非标准端口上遵守CSRF请求,同时仍然为您提供正确的绝对URL.

Answer 2

设置USE_X_FORWARDED_HOST在你的设置,True并确保你把它传递使用Web服务器(proxy)为好.

当django build_absolute_uri()调用它时get_host()- 请参阅下面的django.http.request:

def get_host(self):
    """Returns the HTTP host using the environment or request headers."""
    # We try three options, in order of decreasing preference.
    if settings.USE_X_FORWARDED_HOST and (
            'HTTP_X_FORWARDED_HOST' in self.META):
        host = self.META['HTTP_X_FORWARDED_HOST']
        ...

请参阅X-Forwarded-Host标头的实际使用情况？
