如何使用WCF Rest serice从客户端调用WCF Post方法 [英] How to call WCF Post method from Client Side using WCF Rest serice
问题描述
大家好，
我开发了一个WCF休息服务。 get方法和post方法如何从Web客户端调用wcf rest服务。我的代码是这样的
---- WCF接口方法
Hi All,
I developed one WCF Rest Service. get method and post methods how to call wcf rest service from web client. My code like this
----WCF Interface methods
[OperationContract]
[WebInvoke(UriTemplate = "UpdateTrackDetails",
Method = "POST", RequestFormat = WebMessageFormat.Json,ResponseFormat=WebMessageFormat.Json, BodyStyle = WebMessageBodyStyle.Wrapped)]
string UpdateTrackDetails(string trackdetails);
---接口的WCF实现
公共字符串UpdateTrackDetails（字符串trackdetails）
{
string time =;
DateTime dt = new DateTime（）;
try
{
// System.Web.Script.Serialization.JavaScriptSerializer json = new S. ystem.Web.Script.Serialization.JavaScriptSerializer（）;
string result =0;
TrackDetails _BusTrack = JsonConvert.DeserializeObject< trackdetails>（trackdetails）;
time = _BusTrack.TrackTime;
string daa = Convert.ToDateTime（time）.ToString（dd / MM / yyyy）;
dt = Convert.ToDateTime（daa）;
使用（var context = new SchoolBusTrackEntities（））
{
context.BusTrackDetails.Add（
新的BusTrackDetail
{
BusID = Convert.ToInt32（_BusTrack.BusID），
纬度= _BusTrack.Latitude ，
经度= _BusTrack.Longitude，
// TrackTime = DateTime.Now
追踪时间= dt，
TrackTime1 =时间
}
）;
result = context.SaveChanges（）。 ToString（）;
}
返回结果;
}
catch（Exception ex）
{
返回ex.Message;
}
}

----我的客户电话方式
public string call1（）
{
string sURL =http：// localhost：52305 / SchoolBusTrack.svc / UpdateTrackDetails;
BusTrack1 _test = new BusTrack1（）;
_test.BusID = txtBusID.Text;
_test.Latitude = txtLatitude.Text;
_test。经度= txtLongitude.Text;
_test.TrackTime = txtTrackTime.Text;
_test.TrackTime1 = txtTrackTime1.Text;
string JsonString = new JavaScriptSerializer（）。Serialize（_test）;
var httpWebRequest =（HttpWebRequest）WebRequest.Create（sURL）;
httpWebRequest.ContentType = 文本/ JSON;
httpWebRequest.Method =POST; // GET
string responseText =;
using（var streamWriter = new StreamWriter（httpWebRequest。 GetRequestStream（）））
{
streamWriter.Write（JsonString）; //任何参数
}
var httpResponse =（HttpWebResponse）httpWebRequest.GetResponse（）;
using（var streamReader = new StreamReader（httpResponse.GetResponseStream（）））
{
responseText = streamReader.ReadToEnd（）;
}
返回responseText;
}
---在客户端调用不同的方式
string reqUrl =http://192.168.1.46/BusWCF/SchoolBusTrack.svc/UpdateTrackDetails ;
BusTrack1 _Bus = new BusTrack1（）;
_Bus.BusID = BusID;
_Bus.Latitude =纬度;
_Bus.Longitude =经度;
_Bus.TrackTime = TrackTime;
_Bus.TrackTime1 = TrackTime1;
var JsonString = new JavaScriptSerializer（）。Serialize（_Bus）;
// Response.Write（JsonString）;
byte [] bytes = new UTF8Encoding（）。GetBytes（JsonString.ToString（））;
WebRequest request = WebRequest.Create（reqUrl）;
请求。超时= 2000;
request.Method =POST;
request.ContentType =application / json; charset = utf-8;
request.ContentLength = bytes.Length;
using（StreamWriter writer = new StreamWriter（request.GetRequestStream（）））
{
writer.Write（JsonString）;
}
WebResponse responce = request.GetResponse（）;
流阅读器= responce.GetResponseStream（）;
StreamReader sReader = new StreamReader（reader）;
string outResult = sReader.ReadToEnd（）;
sReader.Close（）;
但是我收到了错误
遥控器服务器返回错误：（400）错误请求。
描述：在执行当前Web请求期间发生了未处理的异常。请查看堆栈跟踪以获取有关错误及其来源的详细信息。代码。
异常详细信息：System.Net.WebException：远程服务器返回错误：（400）错误请求。
请告知我的错误是什么..
谢谢和问候

---calling Differnt way in client side

_Bus.Latitude = Latitude;
_Bus.Longitude = Longitude;
_Bus.TrackTime = TrackTime;
_Bus.TrackTime1 = TrackTime1;
var JsonString = new JavaScriptSerializer().Serialize(_Bus);
// Response.Write(JsonString);
byte[] bytes = new UTF8Encoding().GetBytes(JsonString.ToString());
WebRequest request = WebRequest.Create(reqUrl);
request.Timeout = 2000;
request.Method = "POST";
request.ContentType = "application/json; charset=utf-8";
request.ContentLength = bytes.Length;
using (StreamWriter writer = new StreamWriter(request.GetRequestStream()))
{
writer.Write(JsonString);
}
WebResponse responce = request.GetResponse();
Stream reader = responce.GetResponseStream();
StreamReader sReader = new StreamReader(reader);
string outResult = sReader.ReadToEnd();
sReader.Close();
but i got the error
The remote server returned an error: (400) Bad Request.
Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.
Exception Details: System.Net.WebException: The remote server returned an error: (400) Bad Request.
