Set Response Status Code

Question

I have an API call for which I need to be able to run some checks and potentially return various status codes  I don t need custom views or anything  I just need to return the proper code  If the user hasn t passed proper credentials  I need to return a 401 status  If they haven t sent a supported request format  I need to return a 400 status   Because it s an API  all I really want to do is set the response status and exit with a simple  stupid message about why the request failed  probably using a exit   Just enough to get the job done  but I haven t been able to get this to work right  I ve tried using PHP s header   and Cake s  this- gt header    this is all in the controller   but although I get the exit message  the header shows a 200 OK status   Using the code below  I get the message  but the header isn t set  What am I missing     if    this- gt auth api           header   401 Not Authorized         exit   Not authorized

I don t think you re setting the header correctly  try this   header  HTTP 1 0 401 Unauthorized

I had the same issue with CakePHP 2 0 1  I tried using  header   HTTP 1 1 400 BAD REQUEST       and   this- gt header   HTTP 1 1 400 BAD REQUEST       However  neither of these solved my issue   I did eventually resolve it by using   this- gt header   HTTP 1 1 400  BAD REQUEST       After that  no errors or warning from php   CakePHP    edit  In the last  this- gt header function call  I put a colon     between the 400 and the description text of the error

PHP  lt  5 3  The header   function has a parameter for status code   If you specify it  the server will take care of it from there   header  HTTP 1 1 401 Unauthorized   true  401     PHP   5 4  See Gajus  answer   https   stackoverflow com a 14223222 362536

Why not using Cakes Response Class  You can set the status code of the response simply by this    this- gt response- gt statusCode 200     Then just render a file with the error message  which suits best with JSON

Since PHP 5 4 you can use http response code   http response code 404     This will take care of setting the proper HTTP headers   If you are running PHP  lt  5 4 then you have two options    Upgrade  Use this http response code function implemented in PHP
