Question

当我使用POSTMAN或Fiddler测试它时，我创建了一个C＃WCF项目。我收到一条错误消息：“400 Bad Request”。我也创建了一个C＃windows项目进行测试，结果也是如此。这是我的WCF项目。

[ServiceContract]
public interface IService1
{

    [OperationContract]
    [WebInvoke(Method = "POST",
        ResponseFormat = WebMessageFormat.Json,
        RequestFormat = WebMessageFormat.Json,
        BodyStyle = WebMessageBodyStyle.Wrapped,
        UriTemplate = "api/createpr.json")]
    PRApplication AddPR(RequestData rData);

}

我在测试时使用此代码。

            try
        {
            var httpWebRequest = (HttpWebRequest)WebRequest.Create("http://localhost/WEB_Service_B1/Service1.svc/api/createpr.json");
            httpWebRequest.ContentType = "application/json; charset=utf-8";
            httpWebRequest.Method = "POST";

            using (var streamWriter = new StreamWriter(httpWebRequest.GetRequestStream()))
            {
                string json = "{\"Test\"}";

                streamWriter.Write(json);
                streamWriter.Flush();
                streamWriter.Close();
            }

            var httpResponse = (HttpWebResponse)httpWebRequest.GetResponse();
            using (var streamReader = new StreamReader(httpResponse.GetResponseStream()))
            {
                var result = streamReader.ReadToEnd();
            }
        }
        catch (Exception err)
        {
            MessageBox.Show(err.Message);
        }

我的Web.config中是否还有问题？

Answer 1

BodyStyle = WebMessageBodyStyle.Wrapped

这意味着请求需要是一个完整的json对象。尝试使用以下请求正文：

string json = "{\"rData\": {\"PropertyName\": \"Test\"}}";

其中PropertyName是RequestData字符串类型的公共属性。
