aspnetboilerplate - 将 JSON 序列化从 camelCase 更改为 PascalCase [重复 - 没有解决方案？]
问题描述
我知道这是过去一些问题的重复。但没有真正的解决方案。
我正在使用 .Net Core 3 多页模板。我已经尝试了下面给出的一切。但是没有用。
这是我的应用程序项目界面：
using System.Collections.Generic;
using System.Linq;
using System.Threading.Tasks;
using Abp.Application.Services;
using Abp.Application.Services.Dto;
using TSE.Kalibrasyon.Roles.Dto;
using TSE.Kalibrasyon.Users.Dto;
namespace TSE.Kalibrasyon.Labs
{
public interface ILabAppService : IApplicationService
{
string Test();
Task<List<Entities.Labs.Labs>> GetAllAsync();
System.Threading.Tasks.Task Update(Entities.Labs.Labs input);
System.Threading.Tasks.Task Create(Entities.Labs.Labs input);
}
}
实施是：
using System.Collections.Generic;
using System.Linq;
using System.Text.RegularExpressions;
using System.Threading.Tasks;
using Abp.Application.Services;
using Abp.Application.Services.Dto;
using Abp.Authorization;
using Abp.Domain.Entities;
using Abp.Domain.Repositories;
using Abp.Extensions;
using Abp.IdentityFramework;
using Abp.Linq.Extensions;
using Abp.Localization;
using Abp.Runtime.Session;
using Abp.UI;
using TSE.Kalibrasyon.Authorization;
using TSE.Kalibrasyon.Authorization.Accounts;
using TSE.Kalibrasyon.Authorization.Roles;
using TSE.Kalibrasyon.Authorization.Users;
using TSE.Kalibrasyon.Roles.Dto;
using TSE.Kalibrasyon.Users.Dto;
using Microsoft.AspNetCore.Identity;
using Microsoft.EntityFrameworkCore;
using TSE.Kalibrasyon.Entities.Labs.Dto;
using TSE.Kalibrasyon.Entities.Labs;
using TSE.Kalibrasyon.Labs.Dto;
using Abp.Web.Models;
using Newtonsoft.Json;
using Microsoft.AspNetCore.Mvc;
namespace TSE.Kalibrasyon.Labs
{
//[AbpAuthorize(PermissionNames.Pages_Users)]
public class LabAppService : KalibrasyonAppServiceBase, ILabAppService
{
private readonly IRepository<Entities.Labs.Labs> _labRepository;
public LabAppService(IRepository<Entities.Labs.Labs> labRepository)
{
_labRepository = labRepository;
}
[Microsoft.AspNetCore.Mvc.HttpGet]
public string Test()
{
return "merhaba";
}
[DontWrapResult]
public async Task<List<Entities.Labs.Labs>> GetAllAsync()
{
//var chk = await _labRepository.GetAllListAsync();
return await _labRepository.GetAllListAsync();
}
[DontWrapResult]
//public List<Entities.Labs.Labs> GetAll2()
public object GetAll2()
{
List<Entities.Labs.Labs> chk = _labRepository.GetAllListAsync().Result;
//return _labRepository.GetAllListAsync().Result;
var bak= new { Items = chk, Count = chk.Count() };
return new { Items = chk, Count = chk.Count() };
//return Json(new { Items = chk, Count = chk.Count() }, new JsonSerializerSettings { ContractResolver = new PascalCasePropertyNamesContractResolver() });
}
[DontWrapResult]
public string GetAll3()
{
List<Entities.Labs.Labs> chk = _labRepository.GetAllListAsync().Result;
var obj= new { Items = chk, Count = chk.Count() };
//return Json(new { Items = chk, Count = chk.Count() }, new JsonSerializerSettings { ContractResolver = new PascalCasePropertyNamesContractResolver() });
var settings = new JsonSerializerSettings { TypeNameHandling = TypeNameHandling.All };
//var text = JsonConvert.SerializeObject(configuration, settings);
var text = JsonConvert.SerializeObject(obj);
return text;
//return Json(new { Items = chk, Count = chk.Count() });
}
public async Task Update(Entities.Labs.Labs input)
{
await _labRepository.UpdateAsync(input);
}
public async Task Create(Entities.Labs.Labs input)
{
await _labRepository.InsertAsync(input);
}
}
//public class Data
//{
// public bool requiresCounts { get; set; }
// public int skip { get; set; }
// public int take { get; set; }
//}
}
响应正文是：
[
{
"labName": "BASINÇ KALİBRASYON LABORATUVARI",
"labKod": "BAS",
"bolgeKodu": 5,
"id": 1
}
]
我对该实体的模型是：
using Abp.Domain.Entities;
using Abp.Domain.Repositories;
using System;
using System.Collections.Generic;
using System.ComponentModel.DataAnnotations.Schema;
using System.Text;
namespace TSE.Kalibrasyon.Entities.Labs
{
[Table("Labs")]
public partial class Labs : Entity
{
private readonly IRepository<Labs> _lablarRepository;
//private readonly TownAppService _townAppService;
//private readonly IRepository<Town> _townRepository;
public Labs()
{
//this.Towns = new List<Town>();
//this.Districts = new List<District>();
//this.Neighborhoods = new List<Neighborhood>();
OnCreated();
}
//[System.ComponentModel.DataAnnotations.Key]
//[System.ComponentModel.DataAnnotations.Required()]
//public virtual int Id
//{
// get;
// set;
//}
[System.ComponentModel.DataAnnotations.Required()]
public virtual string LabName
{
get;
set;
}
[System.ComponentModel.DataAnnotations.StringLength(3)]
[System.ComponentModel.DataAnnotations.Required()]
public virtual string LabKod
{
get;
set;
}
[System.ComponentModel.DataAnnotations.Required()]
public virtual int BolgeKodu
{
get;
set;
}
#region Extensibility Method Definitions
partial void OnCreated();
#endregion
}
}
还有一个大问题，我使用 Syncfusion .Net Core Grid 作为第三方工具。它需要一种用于数据库操作的方法，如下所示。
[IgnoreAntiforgeryToken]
public IActionResult UrlDatasource([FromBody]DataManagerRequest dm)
{
Api api=new Api();
//IEnumerable DataSource = Orders.GetAllRecords();
IEnumerable DataSource = api.LabsGetAll();
DataOperations operation = new DataOperations();
if (dm.Search != null && dm.Search.Count > 0)
{
DataSource = operation.PerformSearching(DataSource, dm.Search); //Search
}
if (dm.Sorted != null && dm.Sorted.Count > 0) //Sorting
{
DataSource = operation.PerformSorting(DataSource, dm.Sorted);
}
if (dm.Where != null && dm.Where.Count > 0) //Filtering
{
DataSource = operation.PerformFiltering(DataSource, dm.Where, dm.Where[0].Operator);
}
int count = DataSource.Cast<Entities.Labs.Labs>().Count();
if (dm.Skip != 0)
{
DataSource = operation.PerformSkip(DataSource, dm.Skip); //Paging
}
if (dm.Take != 0)
{
DataSource = operation.PerformTake(DataSource, dm.Take);
}
return dm.RequiresCounts ? Json(new { result = DataSource, count = count }) : Json(DataSource);
}
当我不使用该方法的 [IgnoreAntiforgeryToken] 时。它没有命中带有 HTTP ERROR 415 的方法。
Syncfusion 说，这只是因为驼色外壳并提供添加
services.PostConfigure<MvcJsonOptions>(options =>
{
options.SerializerSettings.ContractResolver = new DefaultContractResolver();
});
进入 StartUp 文件的 ConfigureServices 方法。但我认为它只适用于.net core 2.x。ABP 在 .net core 3.0 上工作对我来说不是一个解决方案
我在 Host App 中的 StartUp.cs 是：

{
//options.SerializerSettings.ContractResolver = new AbpMvcContractResolver(IocManager.Instance)

options.SerializerSettings.ContractResolver = new DefaultContractResolver();
});
services.PostConfigure<MvcNewtonsoftJsonOptions>(options =>

options.SerializerSettings.ContractResolver = new DefaultContractResolver();
});
IdentityRegistrar.Register(services);
AuthConfigurer.Configure(services, _appConfiguration);
services.AddSignalR();
// Configure CORS for angular2 UI
services.AddCors(
options => options.AddPolicy(
_defaultCorsPolicyName,
builder => builder
.WithOrigins(
// App:CorsOrigins in appsettings.json can contain more than one address separated by comma.
_appConfiguration["App:CorsOrigins"]
.Split(",", StringSplitOptions.RemoveEmptyEntries)
.Select(o => o.RemovePostFix("/"))
.ToArray()

.AllowAnyHeader()

);
// Swagger - Enable this line and the related lines in Configure method to enable swagger UI
services.AddSwaggerGen(options =>
{
options.SwaggerDoc("v1", new OpenApiInfo() { Title = "Kalibrasyon API", Version = "v1" });
options.DocInclusionPredicate((docName, description) => true);
// Define the BearerAuth scheme that's in use
options.AddSecurityDefinition("bearerAuth", new OpenApiSecurityScheme()
{
Description = "JWT Authorization header using the Bearer scheme. Example: \"Authorization: Bearer {token}\"",
Name = "Authorization",
In = ParameterLocation.Header,
Type = SecuritySchemeType.ApiKey
});
});
// Configure Abp and Dependency Injection
return services.AddAbp<KalibrasyonWebHostModule>(
// Configure Log4Net logging
options => options.IocManager.IocContainer.AddFacility<LoggingFacility>(
f => f.UseAbpLog4Net().WithConfig("log4net.config")
)
);
}
public void Configure(IApplicationBuilder app, ILoggerFactory loggerFactory)
{
app.UseAbp(options => { options.UseAbpRequestLocalization = false; }); // Initializes ABP framework.
app.UseCors(_defaultCorsPolicyName); // Enable CORS!
app.UseStaticFiles();
app.UseRouting();
app.UseAuthentication();
app.UseAbpRequestLocalization();
app.UseEndpoints(endpoints =>
{
endpoints.MapHub<AbpCommonHub>("/signalr");
endpoints.MapControllerRoute("default", "{controller=Home}/{action=Index}/{id?}");
endpoints.MapControllerRoute("defaultWithArea", "{area}/{controller=Home}/{action=Index}/{id?}");
});
// Enable middleware to serve generated Swagger as a JSON endpoint
app.UseSwagger();
// Enable middleware to serve swagger-ui assets (HTML, JS, CSS etc.)
app.UseSwaggerUI(options =>
{
options.SwaggerEndpoint(_appConfiguration["App:ServerRootAddress"].EnsureEndsWith('/') + "swagger/v1/swagger.json", "Kalibrasyon API V1");
options.IndexStream = () => Assembly.GetExecutingAssembly()
.GetManifestResourceStream("TSE.Kalibrasyon.Web.Host.wwwroot.swagger.ui.index.html");
}); // URL: /swagger
}
}
}
有没有您可能知道的解决方案？提前致谢。
还有，使用 JsonResult 控制属性名称的序列化。但没有用。请问有什么想法吗？
解决方案
在 .NET Core 3.x 中，您现在需要修改JsonSerializerOptions.PropertyNamingPolicy.
对于 PascalCase - 遵循您的原始属性名称 - 设置为null：
services.AddMvc(...)
.AddJsonOptions(jsonOptions =>
{
jsonOptions.JsonSerializerOptions.PropertyNamingPolicy = null;
});
对于小写（或其他自定义命名策略），子类化JsonNamingPolicy并覆盖该ConvertName方法。
services.AddMvc(...)
.AddJsonOptions(jsonOptions =>
{
jsonOptions.JsonSerializerOptions.PropertyNamingPolicy = new JsonLowercaseNamingPolicy();
});
public class JsonLowercaseNamingPolicy : JsonNamingPolicy
{
public override string ConvertName(string name) => name.ToLowerInvariant();
}
