錯誤張貼JSON到WCF REST服務

Question

我有一個WCF REST服務，我正在嘗試用Firefox的REST客戶端測試，

的方法我打電話的簽名是

 [WebInvoke(Method = "POST", UriTemplate = "UploadEvidenceData/{userName}/{password}/{cdb}")] 
    public EvidenceData UploadEvidenceData(string userName, string password, string cdb, EvidenceData evidence) 

數據合同證據

[DataContract(Name = "EvidenceData", Namespace = "http://StudentEvidence.com")] 
public class EvidenceData 
{ 
    [DataMember] 
    public string LearnerID { get; set; } 

    [DataMember] 
    public string UnitID { get; set; } 

    [DataMember] 
    public string AssessorID { get; set; } 

    [DataMember] 
    public int MethodO { get; set; } //int 

    [DataMember] 
    public int MethodEwt { get; set; } //int 

    [DataMember] 
    public int MethodEp { get; set; } //int 

    [DataMember] 
    public int MethodQc { get; set; } //int 

    [DataMember] 
    public int MethodEps { get; set; } //int 

    [DataMember] 
    public int MethodPd { get; set; } //int 

    [DataMember] 
    public int MethodS { get; set; } //int 

    [DataMember] 
    public int MethodEwa { get; set; } //int 

    [DataMember] 
    public int MethodEch { get; set; } //int 

    [DataMember] 
    public int MethodEwe { get; set; } //int 

    [DataMember] 
    public int MethodApel { get; set; } //int 

    [DataMember] 
    public int EvidenceID { get; set; } //int 

    [DataMember] 
    public string EvidenceFileName { get; set; } 

    [DataMember] 
    public int EvidenceFileSize { get; set; } //int 

    [DataMember] 
    public string EvidenceDescription { get; set; } 

    [DataMember] 
    public string AssessorFeedback { get; set; } 

    [DataMember] 
    public string Signature { get; set; } 

    [DataMember] 
    public int RequirementID { get; set; } //int 

    [DataMember] 
    public int ModuleID { get; set; } //int 

    public EvidenceData() 
    { 
     this.LearnerID = string.Empty; 
     this.UnitID = string.Empty; 
     this.AssessorID = string.Empty; 
     this.MethodO = 0; 
     this.MethodEwt = 0; 
     this.MethodEp = 0; 
     this.MethodQc = 0; 
     this.MethodEps = 0; 
     this.MethodPd = 0; 
     this.MethodS = 0; 
     this.MethodEwa = 0; 
     this.MethodEch = 0; 
     this.MethodEwe = 0; 
     this.MethodApel = 0; 
     this.EvidenceID = 0; 
     this.EvidenceFileName = string.Empty; 
     this.EvidenceFileSize = 0; 
     this.EvidenceDescription = string.Empty; 
     this.AssessorFeedback = string.Empty; 
     this.Signature = null; 
     this.RequirementID = 0; 
     this.ModuleID = 0; 
    } 
} 

，當我使用客戶端使用該地址http://something.com/Service/UploadEvidence/user/pass/mydb

和身體，我把

{"AssessorFeedback":"Nothing to report","AssessorID":"32fac8c2-0f9b-4cad-a2e4-55b06e968da0","EvidenceDescription":"some evidence","EvidenceFileName":"Lighthouse.jpg","EvidenceFileSize":561276,"EvidenceID":0,"LearnerID":"61b9eca6-6c3e-4bd3-8963-69d9ad3e5eeb","MethodApel":0,"MethodEch":0,"MethodEp":0,"MethodEps":0,"MethodEwa":0,"MethodEwe":0,"MethodEwt":0,"MethodO":0,"MethodPd":0,"MethodQc":0,"MethodS":0,"ModuleID":1131,"RequirementID":30476,"Signature":null,"UnitID":"c33ea6e1-ac54-46dc-a512-3a2efafd5a0b"} 

和我的應用程序/ JSON

此的自定義頁眉一切工作正常，從一個.NET客戶端，而不是從Firefox 400每次其餘客戶端插件。

任何幫助是非常讚賞

400往往意味着錯誤的HTTP方法。 Firefox客戶端是否使用GET（這需要您的方法具有不同的屬性，並對您的web.config進行調整以允許Web獲取），或者您確定它是POST？

此外，還要檢查該內容類型的問題：Why does my C# client, POSTing to my WCF REST service, return (400) Bad Request?

而且看是否添加RequestFormat = WebMessageFormat.Json到[WebInvoke]屬性裝飾你的服務方法幫助。我認爲這默認爲xml，這可能是.NET客戶端發送的。 http://msdn.microsoft.com/en-us/library/system.servicemodel.web.webinvokeattribute.requestformat.aspx
