Json WCF WebInvoke方法POST
我有一个wcf服务,我想测试向它发布数据。但是我函数的参数从来没有得到任何值Json WCF WebInvoke方法POST,json,wcf,http-post,Json,Wcf,Http Post,我有一个wcf服务,我想测试向它发布数据。但是我函数的参数从来没有得到任何值 [OperationContract] [WebInvoke(UriTemplate = "TestPost", Method = "POST", ResponseFormat = WebMessageFormat.Json, RequestFormat = WebMessageFormat.Json, BodyStyle = WebMessageBodyStyle.W
[OperationContract]
[WebInvoke(UriTemplate = "TestPost", Method = "POST",
ResponseFormat = WebMessageFormat.Json,
RequestFormat = WebMessageFormat.Json,
BodyStyle = WebMessageBodyStyle.WrappedRequest)]
int Test(string value);
public int Test(string value) //Value stays null
{
return 0;
}
我发送的JSON请求,使用Fiddler2构建
http://localhost:49633/Service1.svc/TestPost
User-Agent: Fiddler
Host: localhost:49633
Content-Length: 42
Content-type: application/json
{"value":{"name":"value","name1":"value"}}
我希望参数包含一个JSON字符串,因此基本上我正在创建一个包含JSON对象的JSON请求,因为我希望稍后将JSON对象反序列化为一个自定义对象。你知道为什么value参数保持为null吗
谢谢我正在使用下面的方法将json字符串发布到上面定义的服务中,它适合我: 我的服务:
[WebInvoke(UriTemplate = "TestPost", ResponseFormat = WebMessageFormat.Json, RequestFormat = WebMessageFormat.Json)]
public int Test(string value)
{
Console.Write(value);
return 1;
}
我的客户:
private string UseHttpWebApproach(string serviceUrl, string resourceUrl, string method, string requestBody)
{
string responseMessage = null;
var request = WebRequest.Create(string.Concat(serviceUrl, resourceUrl)) as HttpWebRequest;
if (request != null)
{
request.ContentType = "application/json";
request.Method = method;
}
//var objContent = HttpContentExtensions.CreateDataContract(requestBody);
if(method == "POST" && requestBody != null)
{
byte[] requestBodyBytes = ToByteArrayUsingJsonContractSer(requestBody);
request.ContentLength = requestBodyBytes.Length;
using (Stream postStream = request.GetRequestStream())
postStream.Write(requestBodyBytes, 0, requestBodyBytes.Length);
}
if (request != null)
{
var response = request.GetResponse() as HttpWebResponse;
if(response.StatusCode == HttpStatusCode.OK)
{
Stream responseStream = response.GetResponseStream();
if (responseStream != null)
{
var reader = new StreamReader(responseStream);
responseMessage = reader.ReadToEnd();
}
}
else
{
responseMessage = response.StatusDescription;
}
}
return responseMessage;
}
private static byte[] ToByteArrayUsingJsonContractSer(string requestBody)
{
byte[] bytes = null;
var serializer1 = new DataContractJsonSerializer(typeof(string));
var ms1 = new MemoryStream();
serializer1.WriteObject(ms1, requestBody);
ms1.Position = 0;
var reader = new StreamReader(ms1);
bytes = ms1.ToArray();
return bytes;
}
我对客户端的UseHttpWebApproach调用如下:
string serviceBaseUrl = <<your service base url>>;
string resourceUrl = "/TestPost";
string method = "POST";
string jsonText = "{\"value\":{\"name\":\"value\",\"name1\":\"value\"}}";
UseHttpWebApproach(serviceBaseUrl, resourceUrl, method, jsonText);
参数是字符串,因此其值也应该是字符串。尝试传递
{“value”:“{\“name\”:“value\”,\“name1\”:“value\”}
。虽然我很惊讶服务没有给你一个错误而不是一个空参数。你能试着把BodyStyle删除为WrappedRequest默认的值吗
