快速解决angularJS中用post方法时后台拿不到值的问题

$http.post( "1.php", { id: 1 }).success(function (data) {
  console.log(data);
  });

$http({
 method: 'POST',
 url: '1.php',
 data: { id: 1 }
 }).success(function (data) {
 console.log(data);
 });

<?php
 echo json_encode($_POST);
?>

<form action="1.php" method="post">
 <input type="text" name="tid">
 <input type="submit" value="submit">
</form>

The $httpProvider provider and $http service expose defaults.transformRequest and defaults.transformResponse properties. If a request does not provide its own transformations then these will be applied.

You can augment or replace the default transformations by modifying these properties by adding to or replacing the array.

Angular provides the following default transformations:

Request transformations ($httpProvider.defaults.transformRequest and $http.defaults.transformRequest):

If the data property of the request configuration object contains an object, serialize it into JSON format.
Response transformations ($httpProvider.defaults.transformResponse and $http.defaults.transformResponse):

If XSRF prefix is detected, strip it (see Security Considerations section below).
If JSON response is detected, deserialize it using a JSON parser.

app.config(['$httpProvider', function ( $httpProvider ) {
  $httpProvider.defaults.transformRequest = function ( data ) {
  var str = '';
  for( var i in data ) {
   str += i + '=' + data[i] + '&';
  }
  return str.substring(0,str.length-1);
  }
 }]);
