如何使 NGINX 服务器 JSON 文件类型为 application/json 而不是 text/plain？

如何使 NGINX 服务器 JSON 文件类型为 application/json 而不是 text/plain？

我的服务器以 text/plain 形式提供“manifest.json”文件，这意味着浏览器无法读取它。

肯定有一条线/etc/nginx/config/mime.types

application/json                      json;

但是我在 chrome dev tools 中看到类型错误：

操作系统：Ubuntu 16.04.6

NGINX：1.13.1

答案1

我添加了以下块到/etc/nginx/sites/example.com.conf

location ~ \.json {
    add_header  Content-Type    application/json;
    proxy_pass http://lospec;

    include /etc/nginx/config/proxy/proxy.conf;
}

看起来效果不错。但如果这样做有什么问题，请告诉我。

答案2

该文件可能mime.types未包含在 nginx 配置中，因此无法加载。

请检查一下主文件中是否有类似下面的行nginx.conf。路径nginx.conf可能是/etc/nginx/nginx.conf或/etc/nginx/config/nginx.conf

include /etc/nginx/config/mime.types;
