.net 核心:不完整的 JSON 响应 [英] .net core : incomplete JSON response

问题描述

我正在尝试构建用于训练的简单 API，在我的数据库中，我有用户(名字、姓氏、电子邮件密码、list)和运动(姓名、用户 ID).当我想要我的用户时，一切都很好，我得到了一个充满运动的对象.但是JSON响应不完整，中间被切"了.

I'm trying to build simple API for training, in my database I got users (firstname, lastname, email password, list<sports>) and sports ( name, userID). All is okay when I want to get my users, I got an object populated with sports. But the JSON response is incomplete, it is "cut" in the middle.

[{"firstName":"Nicolas","lastName":"Bouhours","email":"[e-mail]","password":"[e-mail]","sports":[{"name":"Trail","userId":1

这是我的控制器:

// GET: api/Users
[HttpGet]
public IEnumerable<User> GetUsers()
{
    var users = _context.Users.Include(u => u.Sports).ToList();
    return users;
}

还有我的模型:

public class Sport : BaseEntity
{
    public string Name { get; set; }

    public int UserId { get; set; }
    public User User { get; set; }
}

public class User : BaseEntity
{
    public String FirstName { get; set; }
    public String LastName { get; set; }
    public String Email { get; set; }
    public String Password { get; set; }

    public List<Sport> Sports { get; set; }
}

public class SportAppContext : DbContext
{
    public SportAppContext(DbContextOptions<SportAppContext> options) : base(options)
    { }

    public DbSet<User> Users { get; set; }
    public DbSet<Sport> Sports { get; set; }
}

我真的不明白发生了什么，如果你有任何想法

I really don't understand what happen, if you have any idea

推荐答案

我现在遇到了同样的问题.您还可以更改 JSON 序列化/配置设置以忽略自引用循环，如已接受的答案所示 对于这个问题

I'm running into the same issue right now. You can also change the JSON serialization/configuration settings to ignore self-reference loops, as shown in the accepted answer for this question

public void ConfigureServices(IServiceCollection services)
{
    services.AddMvc().AddJsonOptions(options => {
        options.SerializerSettings.ReferenceLoopHandling = ReferenceLoopHandling.Ignore;
    });
}
