POST requests from grunt-connect-proxy plugin do not contain data

问题

It works so far that Angular can make a POST request to my local running Apache server. From that server, I return a Symfony JsonResponse object:

$http.post("/api", {"foo":"bar"})
          .success(function(data, status, headers, config) {
              $scope.data = data;
              console.log(data);
          }).error(function(data, status, headers, config) {
              $scope.status = status;
          });

Now I am stuck with the fact that it only returns []. If I return a hardcoded associative array, it works.

What could be the problem? (plugin)

回答1:

If you are getting [] as data on success, this means your server is giving empty response, thought still a valid response. Try running your API in browser(or better use POSTMAN plugin in Chrome) to check if the same API call is returning [] as a response.

Ok, the solution was to check for content_type:application/json because the $_POST will not get populated if it is set. Angular automaticly does this.

If you don't know this, it is looking for a needle in a haystack. In that regard, this post was extremely helpfull. and following that I stumbled on this page

this line did it

if(0 === strpos($request->headers->get('CONTENT_TYPE'), 'application/json')){
