我的Asp.Net 5 web api服务收到Posted Json为NULL
本文关键字：Posted Json NULL 服务 Net Asp web api 我的 | 更新日期: 2023-09-27 18:20:59
您好，由于我无法将Json数据发送到Asp.Net 5的API服务，我使用在StackOverflow中找到的方法：
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'
但当我发展到更复杂的模型时，这个param方法无法转换像这样的数据模型
{ RoleStatuses: [{Role: "Admin", IsInRole: true}, {Role: "User", IsInRole: false}, ...], UserName: "MyUser" }
当我在API服务中收到这个模型时，UserName被识别，但Array计数=0，当我想将这个数据作为json发送时，UserName和Array都为空，我陷入了这种情况，无法继续，所以请帮助。
多亏了互联网，我找到了放置属性的答案：
[HttpPost]
[Route("UpdateRoles")]
public AdminAccountGenericResponse UpdateRoles([FromBody]RoleStatusUserModel model)
{
[FromBody]在Model参数前面。
POST是：
JSON-
角色状态[Object｛Role="Administrators"，IsUserInRole=false，$$hashKey="Object:53"｝，Object｛Role="Editors"，IsUserInRole=false，$$hashKey="Object:54"｝、Object｛Role="Members"、IsUserInRole=true、$$hashKey＝"Object:55"｝
0Object｛Role="Administrators"，IsUserInRole=false，$$hashKey="Object:53"｝
$$hashKey"对象：53"
IsUserInRole错误
角色"管理员"
1Object｛Role="Editors"，IsUserInRole=false，$$hashKey="Object:54"｝
$$hashKey"对象：54"
IsUserInRole错误
角色"编辑"
2Object｛Role="Members"，IsUserInRole=true，$$hashKey="Object:55"｝
$$hashKey"对象：55"
IsUserInRole真实
角色"会员"
3Object｛Role="Users"，IsUserInRole=true，$$hashKey="Object:56"｝
$$hashKey"对象：56"
IsUserInRole真实
角色"用户"
用户名"Armin"
来源｛"RoleStatuses"：[｛"角色"："Administrators"，"IsUserInRole"：false，"$$hashKey"："object:53"｝，｛"Role"："Editors"，"IsUserInRole"：false，"$$hashKey"："object:54"}，｛：55"｝，｛"角色"："用户"，"IsUserInRole"：true，"$$hashKey"："object:56"｝]，"用户名"："Armin"｝
