[英]Call DELETE method of wcf restful service from client applicaiton
Here is how I try to call the DELETE method from my WCF service: 这是我尝试从WCF服务中调用DELETE方法的方法:
string tmpUrl1 = "http://localhost:1234/MyService.svc/EndPoint/MyMethod";
WebRequest request1 = WebRequest.Create(tmpUrl1);
request1.Method = "DELETE";
byte[] byteArray1 = Encoding.UTF8.GetBytes("{\"idName\":" + newIdName + "}");
request1.ContentType = "application/json";
request1.ContentLength = byteArray1.Length;
Stream dataStream1 = request1.GetRequestStream();
dataStream1.Write(byteArray1, 0, byteArray1.Length);
dataStream1.Close();
WebResponse response1 = request1.GetResponse();
But I get error 400. 但我收到错误400。
Here is the method's name in the wcf: 这是wcf中方法的名称:
[OperationContract]
[WebInvoke(
Method = "DELETE",
RequestFormat = WebMessageFormat.Json,
ResponseFormat = WebMessageFormat.Json,
UriTemplate = "/MyMethod/{deleteRP}/",
BodyStyle = WebMessageBodyStyle.Bare
)]
MyClass MyMethod(string deleteRP);
Where am I making a mistake? 我在哪里出错?
Try enabling Tracing on your service and inspect the trace log for the actual error. 尝试在服务上启用跟踪 ,并检查跟踪日志中的实际错误。 Also your url address should have something like
另外您的网址也应该是
"http://localhost:1234/MyService.svc/EndPoint/MyMethod/55"
rather than 而不是
"http://localhost:1234/MyService.svc/EndPoint/MyMethod" “ http:// localhost:1234 / MyService.svc / EndPoint / MyMethod”
UPDATE: 更新:
private static byte[] ToByteArrayUsingDataContractSer<T>(T requestBody)
{
byte[] bytes = null;
var serializer1 = new DataContractSerializer(typeof(T));
var ms1 = new MemoryStream();
serializer1.WriteObject(ms1, requestBody);
ms1.Position = 0;
var reader = new StreamReader(ms1);
bytes = ms1.ToArray();
return bytes;
}
Now replace the following line 现在替换以下行
byte[] byteArray1 = Encoding.UTF8.GetBytes("{\"idName\":" + newIdName + "}");
with 与
byte[] array = ToByteArrayUsingDataContractSer<string>("{\"idName\":" + newIdName + "}");
