网页API放正在识别查询字符串但不是身体 [英] web api put is recognizing query strings but not body

问题描述

当我在用户传递作为查询字符串（使用的$ HTTP PARAMS），并设置Web API方法寻找他们的URI一切桃色的。但是当我在下面通过他们，用户显示为空。我失去了什么吗？

角功能

  scope.saveChanges =功能（）{
        //创建用户ID的数组
        VAR用户= [];
        angular.forEach（scope.usersInRole，函数（V，K）{
            users.push（v.Key）;
        }）;        VAR数据= {用户：用户};        VAR令牌= angular.element（输入[名称= __ RequestVerificationToken']）VAL（）。        //把服务器更改
        HTTP（{
            网址：config.root +'API /角色/'+ scope.selectedRole +'/用户的，
            方法：把'，
            数据：数据，
            的contentType：应用/ JSON的;字符集= UTF-8，
            标题：{X-XSRF令牌：令牌}，
            xsrfCookieName：__RequestVerificationToken
        }）。成功（功能（结果）{
            //通知用户更改已保存
            。angular.element（'＃myModal）显示（{closeOnBackgroundClick：假}）;
        }）;
    };
 

网页API行动

 公开的Htt presponseMessage把（HTT prequestMessage要求，[FromUri]串角色，[FromBody]字符串[]用户）
            {                返回request.CreateResponse（的HTTPStatus code.NoContent）;
            }
 

解决方案

尝试：数据：用户而不是数据：数据。

在asp.net API，整个请求主体绑定到一个参数。出于这个原因，您不能在动作方法的参数多个参数与 [FromBody] 。只有一个=>我们不需要在请求主体以指定一个属性名称

when i pass in users as a query string (using params in $http) and set the web api method to look for them in the uri everything is peachy. but when i pass them in as below, users shows up as null. what am i missing here?

angular function

scope.saveChanges = function () {
        // create array of user id's
        var users = [];
        angular.forEach(scope.usersInRole, function (v, k) {
            users.push(v.Key);
        });

        var data = { user: users };

        var token = angular.element("input[name='__RequestVerificationToken']").val();

        // put changes on server
        http({
            url: config.root + 'api/Roles/' + scope.selectedRole + '/Users',
            method: 'PUT',
            data: data,
            contentType: "application/json; charset=utf-8",
            headers: { "X-XSRF-Token": token },
            xsrfCookieName: '__RequestVerificationToken'
        }).success(function (result) {
            // notify user changes were saved
            angular.element('#myModal').reveal({ closeOnBackgroundClick: false });
        });
    };

web api action

 public HttpResponseMessage Put(HttpRequestMessage request, [FromUri]string role, [FromBody]string[] user)
            {

                return request.CreateResponse(HttpStatusCode.NoContent);
            }

解决方案

Try: data: users instead of data: data.

In asp.net api, the whole request body is bound to a parameter. For this reason, you cannot have multiple parameters with the [FromBody] in the action method parameters. There is only one => we don't need to specify a property name in the request body.
