Laravel项目无法访问

Question

I've uploaded the project to Laravel, however the site is not shown. I receive the following error log:

[19-May-2017 17:47:38 UTC] PHP Fatal error:  Interface 'JsonSerializable' not found in /home/behnamha/fueltrans.behnamhadipanah.ir/core/vendor/laravel/framework/src/Illuminate/Database/Eloquent/Model.php on line 18

Answer 1

Enable php-json

If you can access the server, check if it's active/installed

Run:

php --re "json"

You should see the following towards the bottom of the response:

- Classes [1] {
    Interface [ <internal:json> interface JsonSerializable ] {

      - Constants [0] {
      }

      - Static properties [0] {
      }

      - Static methods [0] {
      }

      - Properties [0] {
      }

      - Methods [1] {
        Method [ <internal:json> abstract public method jsonSerialize ] {

          - Parameters [0] {
          }
        }
      }
    }
  }

You can also check through your configuration. I use php-fpm while on php 7.1 and go here: /etc/php/7.1/fpm/conf.d

This may vary depending on your configuration, however you should see something along the lines of

20-json.ini -> /etc/php/7.1/mods-available/json.ini
