IIS loading JSON file error 404

Problem description

When the project is published, there are some files that are JSON files that are loaded in the Web page, but when the IIS7 is released, the JSON file is 404, cannot be found, and the address is entered on the URL.

Cause of error

IIS internal mechanism, does not support direct access to the JSON extension file, there is no MIME mapping. Therefore, IIS does not recognize the JSON file and needs to add a MIME map if it needs to support access to the JSON file (default IIS Express does not map)

Solution Solutions

1. In IIS Express the MIME类型 add JSON extension mapping
