我有这个 WCF 服务：

IService.cs：

public interface IService
{
   [OperationContract]
   [WebInvoke(Method = "POST", UriTemplate = "/PostComments", BodyStyle = WebMessageBodyStyle.Wrapped,
    RequestFormat = WebMessageFormat.Json, ResponseFormat = WebMessageFormat.Json)]
   string PostComments(PostComment comment);

 [DataContract]
public class PostComment
{
    private string Id;
    private string FullName;
    private string Email;
    private string Location;
    private string Comments;
    private string Type;

    [DataMember]
    public string id { get { return Id; } set { Id = value; } }
    [DataMember]
    public string fullname { get { return FullName; } set { FullName = value; } }
    [DataMember]
    public string email { get { return Email; } set { Email = value; } }
    [DataMember]
    public string location { get { return Location; } set { Location = value; } }
    [DataMember]
    public string comments { get { return Comments; } set { Comments = value; } }
    [DataMember]
    public string type { get { return Type; } set { Type = value; } }
}

Service.svc.cs：

public string PostComments(PostComment commnt)
        {
            int ItemId;
            string Comments, FullName, Location, Email, Type;

            ItemId = Convert.ToInt32(commnt.id);
            Type = commnt.type;
            Comments = commnt.comments;
            FullName = commnt.fullname;
            Location = commnt.location;
            Email = commnt.email;
            int i = 0;

            if (Type == "Style")
            {
                adp = new SqlDataAdapter("insert into tblComment(intId,strComments,strFullName,strLocation,strEmail,dtPosted,blnApprove) values("+ItemId+",'"+Comments+"','"+FullName+"','"+Location+"','"+Email+"',GetDate(),1)", offcon);
                adp.Fill(ds1,"StComment");
                DataTable dt = ds1.Tables["StComment"];
                i++;
            }
            else if (Type == "Article")
            {
                adp = new SqlDataAdapter("insert into tblNewsComment(intArticleId,strComments,strFullName,strLocation,strEmail,dtPosted,blnApprove) values(" + ItemId + ",'" + Comments + "','" + FullName + "','" + Location + "','" + Email + "',GetDate(),1)", offcon);
                adp.Fill(ds1, "ArtComment");
                DataTable dt = ds1.Tables["ArtComment"];
                i++;
            }
            if (i > 0)
            {
                return "Comment Successfully Submitted.";
            }
            else
            {
                return "Comment falied to Submit.";
            }
        }

web.config文件：

            />
        </binding>
      </webHttpBinding>
    </bindings>
  </system.serviceModel>  
</configuration>

现在，如果我正在使用BasicHttpBindingWCF测试客户端进行测试，那么一切正常。

但是，当我使用WebHttpBinding和测试Google 的 Advanced Rest Client并通过它发布数据时，我收到了这个错误：

服务器在处理请求时遇到错误。异常消息是'格式化程序在尝试反序列化消息时抛出异常：反序列化操作'PostComments'的请求消息正文时出错。遇到了意想不到的字符'T'。'。有关更多详细信息，请参阅服务器日志。异常堆栈跟踪是：

有时这个：

服务器在处理请求时遇到错误。异常消息是“反序列化操作“PostComments”的请求消息正文时出错。OperationFormatter 遇到无效的消息正文。预计会找到名称为“类型”且值为“对象”的属性。找到值'数字'。'。有关更多详细信息，请参阅服务器日志。异常堆栈跟踪是：

我真的不知道我错在哪里，因为这项服务昨天在谷歌的同一个休息客户端上运行良好。我必须尽快在服务器上部署此服务。请帮忙！！！！

[更新 2] 我已经通过 Service Tracker 然后我发现我得到的根值有 Number 并且服务需要 Object. 所以如果它会触发一些事情，因为我现在完全空白......

您正在发布的 json 的所有键都以大写字母开头，您的公共属性（标有小写属性）以小写字母开头。您应该让它们匹配或添加使用 [Datamember(name="key")] 以确保它们正确映射。
