带有ImageFIeld和HTTPS的Django ModelSerializer

Question

我有一个带有图像的模型新闻,这些新闻可以通过JSON REST API加载.服务器使用来自管理局的证书进行签名,所有请求必须使用https完成.

我的问题是,ModelSerializer使用http而不是https序列化ImageField.我该如何改变？

这是代码和输出示例的摘要:

#myProject/models.py
class News(models.Model):
    image = models.ImageField()

#myProject/serializers.py
class NewsSerializer(serializers.ModelSerializer):
    class Meta:
        model = News
        fields = ('image')

#request for a news
https://myDomain/news/the-news-id-here/

#current output
{
    "image": "http://myDomain/media/news/imageName.jpg"
}

#wanted output
{
    "image": "https://myDomain/media/news/imageName.jpg"
}

谢谢大卫

请考虑proxy_set_header X-Forwarded-Proto https;在您的 Nginx 虚拟主机文件中添加，即位于/etc/nginx/sites-available/. 因此，简而言之，您的 conf 文件可能如下所示：

server {
    listen   443 ssl;
    server_name example.com www.example.com;
    root /var/www/html/static_files/;

    client_max_body_size 4G;
    proxy_pass_header Server;
    proxy_set_header Host $http_host;
    proxy_set_header X-Forwarded-Proto https;
    proxy_redirect off;
    proxy_set_header X-Real-IP $remote_addr;
    proxy_set_header X-Scheme $scheme;
    access_log /home/user/API/logs/nginx-access.log;
    error_log /home/user/API/logs/nginx-error.log;

    location /api/ {
        proxy_pass http://127.0.0.1:8000/api/;
    }

    location /media/ {
        proxy_pass http://127.0.0.1:8000/media/;
    }

    # Error pages
    # error_page 500 502 503 504 /home/user/API/500.html;
    ssl_certificate /etc/letsencrypt/live/example.com/fullchain.pem;
    ssl_certificate_key /etc/letsencrypt/live/example.com/privkey.pem;
}

总之，添加后proxy_set_header X-Forwarded-Proto https;。您的 REST API 将被重定向到 https。感谢dukeboy的评论。
