ajax请求标头在开发服务器上具有内容类型application / json，但在生产环境中具有text / html

Question

Running a Drupal website on a LAMP stack. Using the Advanced Poll module , where votes and canceled votes are processed via ajax.

On my dev server this works just fine; on my production server, I get HTTP 500 error ( screenshot ).

Looking at console headers output, I can see that the request is being sent by POST with content-type application/json on my dev server, but on my production server with content-type text/html and gzip content-encoding.

What the hell? Other ajax requests from other modules are working just fine on both servers...

Compare these two screenshots:

PRODUCTION SERVER

Answer 1

It is just mean that your application have some problem/issue on production server. So application send default response type (text/html). You need to check problems through web server logs or any other debug. Remeber all server type error like 404, 500 or similar response type will be text/html until you override this through application
