angularjs - Avoid a property from body of Angular Resource POST request -

-

i creating angular resource follows.

var book = $resource(baseurl + 'v1/users/:username/books/:id', {         username: '@username'         id: '@bookid'       });

i sending post call using save() follows. book.save({username:'testuser', bookid:1, show: true})

this generates url properly

v1/users/testuser/books/1

but sends username,id in body along show:true want avoid. how avoid username,id in body?

here how, acheived it. used transformrequest property of actions , deleted unnecessary properties.

var book = $resource(baseurl + 'v1/users/:username/books/:id', {         username: '@username'         id: '@bookid'       }, {       customsave: {          method: 'post',          transformrequest: function(body) {             delete body.username;             delete body.id;             return angular.tojson(body);          }       } });

suddenly have started receiving above error without changes having been made script. host 1and1 (i know...) the script still works fine on different server, , suspicion there must have been server config change has lead this, although hosts plead ignorance. there's no information on above error @ in google can find - have ideas? server running apache if helps. had similar problem. came out of blue. no php code changed. what changed: php upgraded 5.5.25-1 5.5.26. a security risk in php mail() function has been fixed , newlines in additional_headers allowed no more. because newlines mean: starts email message (and surely don't want inject newlines through headers followed evil message). what have worked fine, e.g. having newlines after headers or passing whole message additional_headers , function no more. solution : sanitize headers. no multiple newlines in additional_headers argument. these count "multiple or malformed newlines":...
