将JSON发布到WCF Rest Service时出错

Question

我有一个WCF Rest服务，我正在尝试使用Firefox Rest Client进行测试，

我正在调用的方法的签名是

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

数据合同的证据是

    [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;
    }
}

当我使用客户端时，请使用地址http://something.com/Service/UploadEvidence/user/pass/mydb

在我身上

{"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"}

而且我有application / json的自定义标头

所有这些都可以从.net客户端正常运行，但不能每次都从firefox 400的其余客户端插件正常运行。

很感谢任何形式的帮助

400通常意味着错误的Http方法。 Firefox客户端是否使用GET（这将要求您的方法使用不同的属性，并对Web.config进行调整以允许Web获取），或者确定是POST？

此外，请检查此内容类型问题： 为什么我的C＃客户端（发布到WCF REST服务）过后返回（400）错误请求？

另请参阅是否将RequestFormat = WebMessageFormat.Json添加到[WebInvoke]属性以装饰服务方法是否[WebInvoke]帮助。 我认为这默认为xml，这可能是.NET客户端发送的内容。 http://msdn.microsoft.com/zh-CN/library/system.servicemodel.web.webinvokeattribute.requestformat.aspx
