Angular 2＆.NET核心Web Api HttpPost问题

Question

我在同一主题上看到过一两个帖子，但这两个问题的解决方案都不适合我，所以我会在这里问一下。

我有一个调用.netCore（1.0）Web API的角2（2.4）应用程序。

我的获取请求到web api工作正常。我的web api允许使用所有的方法（它确实限制了原点，但因为get可以工作，所以我觉得这不是问题）。

我的请求到达API，但请求内容未反序列化到参数对象中。 webapi上的参数始终为空。

目前我的web API方法是（用于测试目的）：

[HttpPost]   
    public Member Post([FromBody] DocMe.Model.Provider.Member member) 
    { 
     return member; 
    } 

我的要求是这样的：

我的代码生成请求从角是：

public post(url: string, data: any): Observable<Response> {  
    this.headers = new Headers(); 
    this.headers.append('Content-Type', 'application/json'); 
    this.headers.append('Accept', 'application/json'); 

    let token = this.authService.GetToken(); 

    if (token !== '') { 
     this.headers.append('Authorization', 'Bearer ' + token); 
    }  
    return this.http.post(url, JSON.stringify(data), { headers: this.headers }); 
} 

devtools ima中的Request Payload ge准确地表示传入方法的数据对象的内容。

当我调试该方法时，我看到呼叫通过签名但通过“member”参数= null。请求负载与成员类型的属性相匹配（这里的异常是有效负载是camelCase，而成员类型是PascalCase）。

我POCO的定义是：

public class Member 
{ 
    public Member() 
    { 
     this.Id = Guid.NewGuid(); 
     this.MemberTypeId = 1; 
     this.Deleted = false; 

     this.MemberPractices = new HashSet<MemberPractice>(); 
     this.Educations = new HashSet<Education>(); 
     this.Insurances = new HashSet<Insurance>(); 
     this.Languages = new HashSet<Language>(); 
     this.Specialties = new HashSet<Specialty>(); 
     this.WorkHours = new HashSet<WorkHour>(); 
     this.WorkHoursOverrides = new HashSet<WorkHoursOverride>(); 
    } 

    [Key]   
    [Display(Name = "Id")] 
    public Guid Id { get; set; } // uniqueidentifier, not null   
    [Display(Name = "Member Type Id")] 
    public int MemberTypeId { get; set; } // int, not null 
    [MaxLength(50)] 
    [StringLength(50)] 
    [Display(Name = "NPI")] 
    public string NPI { get; set; } // varchar(50), null 
    [MaxLength(100)] 
    [StringLength(100)] 
    [Display(Name = "First Name")] 
    public string FirstName { get; set; } // nvarchar(100), null 
    [MaxLength(100)] 
    [StringLength(100)] 
    [Display(Name = "Last Name")] 
    public string LastName { get; set; } // nvarchar(100), null 
    [MaxLength(256)] 
    [StringLength(256)] 
    [Display(Name = "Contact Email")] 
    public string ContactEmail { get; set; } // nvarchar(256), null 
    [MaxLength(10)] 
    [StringLength(10)] 
    [Display(Name = "Gender")] 
    public string Gender { get; set; } // varchar(10), null 
    [MaxLength] 
    [Display(Name = "Biography")] 
    public string Biography { get; set; } // varchar(max), null 
    [MaxLength(450)] 
    [StringLength(450)] 
    [Display(Name = "Identity Id")] 
    public string IdentityId { get; set; } // nvarchar(450), null   
    [Display(Name = "Deleted")] 
    public bool Deleted { get; set; } // bit, not null 
    [Display(Name = "Deleted Date")] 
    public DateTime? DeletedDate { get; set; } // datetime, null 
    [Display(Name = "Deleted By")] 
    public Guid? DeletedBy { get; set; } // uniqueidentifier, null 

    [ForeignKey("Id")] 
    public LkupMemberType LkupMemberType { get; set; } 
    public ICollection<MemberPractice> MemberPractices { get; set; } 
    public ICollection<Education> Educations { get; set; } 
    public ICollection<Insurance> Insurances { get; set; } 
    public ICollection<Language> Languages { get; set; } 
    public ICollection<Specialty> Specialties { get; set; } 
    public ICollection<WorkHour> WorkHours { get; set; } 
    public ICollection<WorkHoursOverride> WorkHoursOverrides { get; set; } 
} 

我的前端模式，即负责填充请求负载是：

export class ProviderModel { 
public id: string; 
public npi: string; 
public firstName: string; 
public lastName: string; 
public contactEmail: string; 
public gender: string; 
public biography: string; 
public specialties: SpecialityModel[]; 
public educations: EducationModel[]; 
public insurances: InsuranceModel[]; 
public languages: LanguageModel[]; 

constructor() { 
    this.id = null; 
    this.specialties = []; 
    this.educations = []; 
    this.insurances = []; 
    this.languages = []; 
} 
} 

鉴于.NET核心有多新，我不知道如果我做错了什么，或者有什么我可能遇到的错误。

我一直在盯着这个问题几天，所以我想把它放在那里来测试我的理智，希望它解决了，所以我可以继续从应该是相对微不足道的东西。

更新：我怀疑HashSet是问题。考虑编写你自己的JsonConverter for HashSet。

你有没有配置你的Web API的SerializerSettings解决骆驼外壳？

services.AddMvc().AddJsonOptions(options => 
        { 
         options.SerializerSettings.ContractResolver = 
          new CamelCasePropertyNamesContractResolver(); 
        });
