This is similar to Kannan s answer  However  this fixes an issue where the token should not be sent to cross-domain sites  This will only set the header if it is a local request   HTML    lt meta name  csrf-token  content     csrf token       gt    JS     ajaxSetup       beforeSend  function xhr  type            if   type crossDomain                xhr setRequestHeader  X-CSRF-Token      meta name  csrf-token     attr  content

Another way to resolve this is to use the  token field in ajax data and set the value of   csrf token     in blade  Here is a working code that I just tried at my end     ajax       type   POST       url    your url       data    somefield   Some field value    token     csrf token             success  function  data           console log data              error  function  data  textStatus  errorThrown            console log data

Even though you have a csrf token  if you are authenticate your controller actions using Laravel Policies you can have 419 response as well  In that case you should add necessary policy functions in your Policy class

This works great for those cases you don t require a form   use this in header    lt meta name  csrf-token  content     csrf token       gt    and this in your JavaScript code     ajaxSetup           headers             X-CSRF-TOKEN     lt  php echo csrf token     gt

User · Answer

use this in your page   lt meta name  csrf-token  content     csrf token       gt    and in your ajax used it in data    token       csrf token           that is     ajax             url    fetch-company     companyId            dataType    json             type   POST             data                        token       csrf token                                       contentType  false            processData  false            success function response                   console log response                          Thanks

2019 Laravel Update  Never thought i will post this but for those developers like me using the browser fetch api on Laravel 5 8 and above  You have to pass your token via the headers parameter   var  token       csrf token      fetch    url  add new comment                         method   POST                   headers                         X-CSRF-TOKEN    token                       Content-Type    application json                                      body  JSON stringify name  email  message  article id                 then r   gt                    return r json                   then results   gt      catch err   gt  console log err

I had  SESSION SECURE COOKIE set to true so my dev environment didn t work when logging in  so I added SESSION SECURE COOKIE false to my dev  env file and all works fine my mistake was changing the session php file instead of adding the variable to the  env file

If you are loading  js from a file you have to set a variable with the csrf token in your  main   blade php file where you are importing the  js and use the variable in your ajax call   index blade php           lt script src     asset  js anotherfile js       gt  lt  script gt   lt script type  text javascript  gt          var token       csrf token         lt  script gt    anotherfile js    ajax       url   yourUrl       type   POST       data              token   token            dataType   json       beforeSend function              do stuff            success  function data              do stuff            error  function data              do stuff            complete  function              do stuff
