$ http方法:"发布"没有传递数据

我使用angular' s $ http:

$http({
                url: '/api/Movies/UpdateMovie',
                method: "POST",
                data: movie,
                headers: { 'Content-Type': 'application/x-www-form-urlencoded' }

            })

检查客户端我看到电影正确填充,但是当向服务器发送数据时,电影模型没有填充发布的数据(或者可能没有发布数据),我使用web api进行服务。我服务器上的电影模型是:

 public class Movie
{
    public int Id { get; set; }

    [Required]
    [StringLength(256, ErrorMessage = "Maximum Title length is 256.")]
    public string Title { get; set; }

    [Required]
    [StringLength(256, ErrorMessage = "Maximum Director length is 256.")]
    public string Director { get; set; }

    [Required]        
    public decimal Price { get; set; }
}

如何将电影作为数据传递?

您可以将对象解析为表单数据,也许这个要点https://gist.github.com/ghinda/8442a57f22099bdb2e34对您有用,无论如何您可以将内容类型更改为application / json,如下所示:

标题:{'Content-Type':'application / json'}

使用此功能:

  var param = function (obj) {
        var query = '', name, value, fullSubName, subName, subValue, innerObj, i; for (name in obj) {
            value = obj[name]; if (value instanceof Array) {
                for (i = 0; i < value.length; ++i)
                { subValue = value[i]; fullSubName = name + '[' + i + ']'; innerObj = {}; innerObj[fullSubName] = subValue; query += param(innerObj) + '&'; }
            } else if (value instanceof Object) {
                for (subName in value)
                { subValue = value[subName]; fullSubName = name + '[' + subName + ']'; innerObj = {}; innerObj[fullSubName] = subValue; query += param(innerObj) + '&'; }
            } else if (value !== undefined && value !== null) query += encodeURIComponent(name) + '=' + encodeURIComponent(value) + '&';
        } return query.length ? query.substr(0, query.length - 1) : query;
    };   // Override $http service's default transformRequest  $httpProvider.defaults.transformRequest = [function(data) {    return angular.isObject(data) && String(data) !== '[object File]' ? param(data) : data;  }];}); 

并设置

data: param(logOn), headers: { 'Content-Type': 'application/x-www-form-urlencoded' }

现在可行。

在您的代码中尝试:

var movie = {};
movie.Title = "Title";
movie.Director = "Director";
movie.Price = 0.50;

并删除:headers: { 'Content-Type': 'application/x-www-form-urlencoded' }

$http({
   url: '/api/Movies/UpdateMovie',
   method: "POST",
   data: movie
});
