c# - 反序列化 Json 无法使用 NewtonSoft 将字符串转换为对象

问题描述

{
  "access_token":"asfdasfdsf",
  "token_type":"bearer",
  "expires_in":15179999,
  "refresh_token":"sdsfsf",
  ".issued":"Sat, 28 Apr 2018 03:05:12 GMT",
  ".expires":"Sat, 20 Oct 2018 19:45:12 GMT",
  "ip_address":"111.111.11.1",
  "client_id":"asdsdfsf",
  "user":"{\r\n \"Active\": true,\r\n \"DisplayName\": \"Sakib Hasan\",\r\n \"Email\": \"test@testc.om\",\r\n \"EmailVarified\": true,\r\n \"Language\": \"en-US\",\r\n \"PhoneNumber\": null,\r\n \"ProfileImageUrl\": null,\r\n \"Roles\": [\r\n \"anonymous\",\r\n \"admin\"\r\n ],\r\n \"TenantId\": \"asfsf\",\r\n \"UserName\": \"test@testc.com\",\r\n \"FirstName\": null,\r\n \"UserSignup\": false,\r\n \"ProfileImageId\": null,\r\n \"EverLoggedIn\": true,\r\n \"PersonIdentifier\": null,\r\n \"UserId\": \"sdfsff\"\r\n}",
  "may_access":""
}

我正在尝试将上述字符串反序列化为我的 C# 对象。我的课程如下所示

internal class TokenResponse
{
    [JsonProperty("access_token")]
    public string AccessToken { get; set; }

    [JsonProperty("token_type")]
    public string TokenType { get; set; }

    [JsonProperty("refresh_token")]
    public string RefreshToken { get; set; }

    [JsonProperty("client_id")]
    public string ClientId { get; set; }

    [JsonProperty("user")]
    public TokenUser User { get; set; }
}

internal class TokenUser
{
    [JsonProperty("DisplayName")]
    public string DisplayName { get; set; }

    [JsonProperty("Email")]
    public string Email { get; set; }

    [JsonProperty("ProfileImageUrl")]
    public string ProfileImageUrl { get; set; }

    [JsonProperty("UserName")]
    public string UserName { get; set; }

    [JsonProperty("FirstName")]
    public string FirstName { get; set; }

    [JsonProperty("UserId")]
    public string UserId { get; set; }
}

现在当我尝试使用 Newtonsoft 反序列化

tokenResponse = JsonConvert.DeserializeObject<TokenResponse>(jsonTokenResponse);

我得到无法将字符串转换为用户错误。我在这里错过了什么吗？

解决方案

像这样试试

internal class TokenResponse
{
    [JsonProperty("access_token")]
    public string AccessToken { get; set; }

    [JsonProperty("token_type")]
    public string TokenType { get; set; }

    [JsonProperty("refresh_token")]
    public string RefreshToken { get; set; }

    [JsonProperty("client_id")]
    public string ClientId { get; set; }

    [JsonProperty("user")]
    public string User { get; set; }

    [JsonIgnore]
    public TokenUser UserToken { get; set; }

}



internal class TokenUser
{
    [JsonProperty("DisplayName")]
    public string DisplayName { get; set; }

    [JsonProperty("Email")]
    public string Email { get; set; }

    [JsonProperty("ProfileImageUrl")]
    public string ProfileImageUrl { get; set; }

    [JsonProperty("UserName")]
    public string UserName { get; set; }

    [JsonProperty("FirstName")]
    public string FirstName { get; set; }

    [JsonProperty("UserId")]
    public string UserId { get; set; }
}


tokenResponse = JsonConvert.DeserializeObject<TokenResponse>(jsonTokenResponse);
tokenResponse.UserToken = JsonConvert.DeserializeObject<TokenUser>(tokenResponse);

因为您的用户属性在期待 TokenUser 时得到一个字符串
