我有這樣的WCF服務：WCF是給400錯誤請求的錯誤在POST方法
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.";
}
}

現在，如果我正在與BasicHttpBinding和測試WCF測試客戶端然後一切工作正常。
但是當我通過那麼我得到與WebHttpBinding工作和測試谷歌的高級REST客戶端和公佈數據這個錯誤：
服務器遇到錯誤處理請求。 消息的例外情況是：'格式化程序在嘗試對 進行反序列化時拋出異常：對操作'PostComments'的請求主體 消息進行反序列化時出錯。遇到意外字符 'T'。'。查看服務器日誌獲取更多詳細信的異常堆棧跟蹤是：

並且有時這樣的：

我真的不知道我在哪裏錯了，因爲這項服務是昨天罰款谷歌同其他客戶端上工作。 我必須儘快在服務器上部署此服務。 請幫忙!!!!

[UPDATE 2] 我已經通過服務追蹤器，然後我發現，我得到的數值和服務的根值是期待對象。 因此，如果它會觸發的東西，因爲我現在完全是空白...
請使用客戶端發佈您提交給服務的請求。 – shambulator
我正在使用Google的Rest客戶端 請求URL是http://192.168.1.2:801/Service.svc/PostComment 然後在參數中我發送的值ItemId，FullName，Email等 –
請使用類似的東西[Fiddler]（http://www.fiddler2.com/fiddler2/）捕獲Google客戶端發送給您的服務的實際請求（包括標頭和POST內容），然後使用這些詳細信息更新您的問題。 – shambulator
