Question

我使用以下内容：

    var url = '/api/Test/Mark';
        $http('POST', url, $scope.content.answers)
            .success(function (data, status, headers, config) {
                $scope.content = data.text;
            })
            .error(function (data, status, headers, config) {
                alert("Error: No data returned from " + url);
            });

当我尝试调用它时，这会给我一个错误：

TypeError: Cannot use 'in' operator to search for '3' in POST

有人可以就我可能做错的事给我建议吗？注意$ scope.content.answers是一个数据数组。

你在使用$ http

做错了

试试这个

  var url = '/api/Test/Mark';

         $http({
                method: 'POST',
                url: url
                data: $scope.content.answers // this should be a object e.g { a : 'one', b: 'Two' }
            })
            .success(function (data, status, headers, config) {
            $scope.content = data.text;
        })
        .error(function (data, status, headers, config) {
            alert("Error: No data returned from " + url);
        });

如何在$ http中使用POST将对象发送到服务器？
