POST Web API 4 için parametre parametresi JSID gövdesi

Question

ile Fiddler'den çağrıldığında bazı eski veritabanı kodlarına göre çok basit bir Web API 4 denetleyicim var. Böyle böyle varlık:

public class Employee 
{ 
    public string EmploymentStatus { get; set; } 
    public string CompanyCode { get; set; } 
    public string Division { get; set; } 
    public string OrgLevel1Code { get; set; } 
    public string OrgLevel2Code { get; set; } 
    public string OrgLevel3 { get; set; } 
    public string StoreName { get; set; } 
    public string EmployeeNumber { get; set; } 
    public string EmployeeFirstName { get; set; } 
    public string EmployeeMiddleInitial { get; set; } 
    public string EmployeeLastName { get; set; } 
    public string EmailAddress { get; set; } 
    public string JobCode { get; set; } 
    public string DateInJob { get; set; } 
    public string OriginalHire { get; set; } 
} 

yöntem aşağıdaki gibidir:

public HttpResponseMessage PostEmployee(Employee item) 
    { 
     DataHelpers.AddUser(item.CompanyCode, item.Division, item.OrgLevel1Code, item.OrgLevel2Code, item.OrgLevel3, item.EmployeeFirstName, item.EmployeeMiddleInitial, item.EmployeeLastName, item.EmailAddress, item.JobCode, item.OriginalHire); 
     var response = Request.CreateResponse<Employee>(HttpStatusCode.Created, item); 
     string uri = Url.Link("DefaultApi", new { id = item.EmployeeNumber }); 
     response.Headers.Location = new Uri(uri); 
     return response; 
    } 

böyle Fiddler aracılığıyla POST:

POST /api/identity HTTP/1.1 
User-Agent: Fiddler 
Host: localhost:1421 
Content-Length: 382 
contentType: "application/json; charset=utf-8" 
dataType: 'json' 

{ 
"employmentStatus":"zzz", 
"companyCode":"Titlemax", 
"division":"bbb", 
"orgLevel1Code":"ccc", 
"orgLevel2Code":"ddd", 
"orgLevel3":"eee", 
"storeName":"fff", 
"employeeNumber":"12343", 
"employeeFirstName":"Bill", 
"employeeMiddleInitial":"A", 
"employeeLastName":"sempf", 
"emailAddress":"bill@sempf.net", 
"jobCode":"GM", 
"dateInJob":"8/7/2005", 
"originalHire":"8/7/2005" 
} 

Ben .NET ve bir istisna olsun öğe parametresi boş.

{"Message":"An error has occurred.","ExceptionMessage":"Object reference not set to an instance of an object.","ExceptionType":"System.NullReferenceException"} 

Neyi eksik? Web API'sinde yeniyim. Şimdiden teşekkürler.

Bu, Fiddler'daki istek biçimi olduğunu düşünüyorum. Besteci sekmesinden Content-Type başlığına

tırnak işaretlerini kaldırmayı deneyin:

POST http://localhost:1421/api/identity HTTP/1.1 

talep Başlıkları:

User-Agent: Fiddler 
Host: localhost:1421 
Content-Type: application/json; charset=utf-8 

talep Gövde:

{ 
    "employmentStatus":"zzz", 
    "companyCode":"Titlemax", 
    "division":"bbb", 
    "orgLevel1Code":"ccc", 
    "orgLevel2Code":"ddd", 
    "orgLevel3":"eee", 
    "storeName":"fff", 
    "employeeNumber":"12343", 
    "employeeFirstName":"Bill", 
    "employeeMiddleInitial":"A", 
    "employeeLastName":"sempf", 
    "emailAddress":"bill@sempf.net", 
    "jobCode":"GM", 
    "dateInJob":"8/7/2005", 
    "originalHire":"8/7/2005" 
} 

Tepki:
