How can I change the Content-Type?

回答1:

It is the issue on the server side. If you have control to the Apache server, add following line in httpd.conf

application/json            json

EDIT : I was wrong of the syntax with my answer above. The lines like above should go into mime.types file as @James suggests. But you can use AddType directive and specify mime types in httpd.conf as well.

AddType application/json .json

回答2:

You'll need to add an appropriate entry for .json to the Apache mime.types file. See Setting up MIME Types with Apache

回答3:

If you don't have access to httpd.conf (like in many cases) you can create a .htaccess file and simply write AddType application/json .json inside. Put it next your json file and it should be OK !

回答4:

You can't change the content type for a .json file. Probably the error comes from the javascript, ther you sould change or parse as Json
