Question

你好我做了一个rails api和angularJs的项目，我发现了以下错误。

angular.js：11821 POST http://localhost:3000/people 400（错误请求）

我找不到原因。

以下代码。

Rails控制器

 # POST /people
  def create
    @person = Person.new(person_params)

    if @person.save
      render json: @person, status: :created, location: @person
    else
      render json: @person.errors, status: :unprocessable_entity
    end
  end

AngularJS

$scope.SendData = function () {
           // use $.param jQuery function to serialize data from JSON 
            var data = $.param({
                name: $scope.name,
                age: $scope.age,
                gender:$scope.gender,
                lonlat:$scope.lonlat
            });

            var config = {
                headers : {
                    'Content-Type': 'application/x-www-form-urlencoded;charset=utf-8;'
                }
            }

            $http.post('http://localhost:3000/people', data, config)
            .then(function (data, status, headers, config) {
                $scope.PostDataResponse = data;
            })
            .catch(function (data, status, header, config) {
                $scope.ResponseDetails = "Data: " + data +
                    "<hr />status: " + status +
                    "<hr />headers: " + header +
                    "<hr />config: " + config;
            });
        };

HTML

<div ng-app="myApp" ng-controller="person">
<div class="modal-body">
<div class="form-group">
<label for="exampleInputEmail1">Name:</label>
<input type="text" class="form-control" name="name" ng-model="name" placeholder="Email">
</div>
<div class="form-group">
<label for="exampleInputEmail1">age:</label>
<input type="text" class="form-control" name="age" ng-model="age" placeholder="Email">
</div>
<div class="form-group">
<label for="exampleInputEmail1">gender:</label>
<input type="text" class="form-control" name="gender" ng-model="gender" placeholder="Email">
</div>
<div class="form-group">
<label for="exampleInputEmail1">lonlat:</label>
<input type="text" class="form-control" name="lonlat" ng-model="lonlat" placeholder="Email">
</div>
<button ng-click="SendData()"
class="btn btn-default">Submit</button>

    {{ PostDataResponse }}

感谢您的聆听

我看不到你的person_params定义，但是如果它就像是由rails生成器生成的那样，你就缺少将params包装在person哈希

中

var data = $.param({person: 
    { name: $scope.name,
      age: $scope.age,
      gender:$scope.gender,
      lonlat:$scope.lonlat }
});

Angularjs与rails API休息400（不良请求）
