Question

您好，因为我无法将Json数据发送到Asp.Net 5的API服务，我使用的方法是我在StackOverflow中找到的：

var param = function (obj) {
        var query = '';
        var 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;
    };

我设置：

'Content-Type': 'application/x-www-form-urlencoded'

但是当我进展到更复杂的模型时，这种param方法无法转换数据模型，如：

{ RoleStatuses: [{Role: "Admin", IsInRole: true}, {Role: "User", IsInRole: false}, ...], UserName: "MyUser" }

当我在API服务中收到此模型时，UserName被识别但是Array count = 0，当我想将此数据作为json发送时，UserName和Array都为null，我陷入了这种情况并且无法继续下去，所以请帮忙。

Answer 1

感谢互联网，我发现我的答案是放置属性：

[HttpPost]
    [Route("UpdateRoles")]
    public AdminAccountGenericResponse UpdateRoles([FromBody]RoleStatusUserModel model)
    {

Model参数前面的

[FromBody] 。

Answer 2

POST是：

JSON

RoleStatuses [Object {Role =“Administrators”，IsUserInRole = false，$$ hashKey =“object：53”}，Object {Role =“Editors”，IsUserInRole = false，$$ hashKey =“object：54”}，Object {Role =“Members”，IsUserInRole = true，$$ hashKey =“object：55”}，Object {Role =“Users”，IsUserInRole = true，$$ hashKey =“object：56”}]

0 对象{Role =“Administrators”，IsUserInRole = false，$$ hashKey =“object：53”}

$$ hashKey “对象：53”

的isUserInRole 假

角色 “管理员”

1 对象{Role =“Editors”，IsUserInRole = false，$$ hashKey =“object：54”}

$$ hashKey “对象：54”

的isUserInRole 假

角色 “编辑”

2 对象{Role =“Members”，IsUserInRole = true，$$ hashKey =“object：55”}

$$ hashKey “对象：55”

的isUserInRole 真

角色 “成员”

3 对象{Role =“Users”，IsUserInRole = true，$$ hashKey =“object：56”}

$$ hashKey “对象：56”

的isUserInRole 真

角色 “用户”

用户名 “阿明”

来源 { “RoleStatuses”：[{ “角色”： “管理员”， “的isUserInRole”：假， “$$ hashKey”： “对象：53”}，{ “角色”： “编辑” “的isUserInRole”：假， “$$ hashKey”： “对象：54”}，{ “角色”： “成员”， “的isUserInRole”：真， “$$ hashKey”：“对象：55 “}，{” 角色 “：” 用户”， “的isUserInRole”：真， “$$ hashKey”： “对象：56”}]， “用户名”： “阿明”}

客户服务：

updateRoles: function (roleStatusUserModel, successSucceed, successFailed, error) {                
            $http({
                url: '/api/AdminAccount/UpdateRoles',
                method: "POST",
                data: JSON.stringify(roleStatusUserModel),
                headers: {

                       theError = data.Error;

                   error();
               });
        }

和Api服务：

    [HttpPost]
    [Route("UpdateRoles")]
    public AdminAccountGenericResponse UpdateRoles(RoleStatusUserModel model)
    {

        ValidateRequestHeader(Request);

        if (!Authorize(Context, Request, new string[] { "Administrators" }))
            throw new ApplicationException("Not Authorized");

        var roles = Roles.GetAllRoles();
        //MembershipUser user = Membership.GetUser(model.UserName);

        foreach (string role in roles)
        {
            RoleStatus roleStat = model.RoleStatuses.FirstOrDefault(rs => rs.Role == role);

            if (roleStat != null)
            {
                if (roleStat.IsUserInRole == true && !Roles.IsUserInRole(model.UserName, role))
                {
                    Roles.AddUserToRole(model.UserName, role);
                }
                else if (roleStat.IsUserInRole == false && Roles.IsUserInRole(model.UserName, role))
                {
                    Roles.RemoveUserFromRole(model.UserName, role);
                }
                else
                { }
            }
            else
            {
                return new AdminAccountGenericResponse
                {
                    Success = false,
                    Message = "",
                    Error = "Role is null."
                };
            }
        }

        return new AdminAccountGenericResponse
        {
            Success = true,
            Message = "Roles Updated",
            Error = ""
        };
    }

模特：

public class RoleStatus
{
    public string Role { get; set; }
    public bool IsUserInRole { get; set; }
}

public class RoleStatusUserModel
{
    public List<RoleStatus> RoleStatuses { get; set; }
    public string UserName { get; set; }
}

我的Asp.Net 5 web api服务收到了发布的Json为NULL
