java - Getting a 411 Length Required error when parameters are very long -

i executing post request angular js against java servlet running on google app engine. code works fine, unfortunately i've noticed if 1 (or more) parameters long following error:

error: length required

post requests require content-length header.

this angular js code:

app.controller('mycontroller', ['$scope', '$http', '$log', function($scope,$http,$log) {  this.myfunction = function() {  $http({     method: 'post',     url: '/myservlet',     params: { method: 'my_method', param1 : $("#param1").val(), param 2: ... } }).success(function(data) {  }).error(function(data) {  });  }; } 

param1, param2 etc different fields, textarea though. suggestion? don't know do.

edit: tried setting content-length in header myself error expected...

headers : { 'content-length' : 0 }, 

refused set unsafe header "content-length"

so basically, if set content-length browser refuses execute call, if don't set server says it's required... can do?

the params argument using used pass variables as part of url when method post ($http docs). pass information in body of post request have use data argument.

so, request should be:

$http({     method: 'post',     url: '/myservlet',     data: { method: 'my_method', param1 : $("#param1").val(), param 2: ... } }).success(function(data) {  }).error(function(data) {  });
