Hi All,

I want to pass JSON Object to WCF service,
Here is my service method:

C#

[OperationContract]
       [WebInvoke(Method="POST", RequestFormat=WebMessageFormat.Json,     ResponseFormat=WebMessageFormat.Json,        UriTemplate = "/UplodImageAndroid")]
       bool uploadImageAndroid(CustomImage custImg);

C#

public bool uploadImageAndroid(CustomImage custImg)
        {
// logical stuf
}

Calling from jquery :

HTML

$(document).ready(function(){
$("#GetUserDetails").click(function(){

var searchRequest = new Object(); 
    searchRequest.fileName = "Chris";  

		$.ajax({
			type:"POST",
			url:"http://localhost/TestAndroidWcfService/Service1.svc/UplodImageAndroid",
			ProcessData:false,			
			contentType:"application/json;charset=utf-8",
			dataType:"json",
			data:searchRequest,			
			success:function(data){
			alert("Success:"+ data);
			},
			error:function(xhr,status,error){
			alert("Error"+error);
			}
		});
		alert("Hi2");
	});
});

Here I am getting error message as Bad Request!!

How to make it work? What is the mistake in code?

Please suggest.

Thanks
Avinash

the type of receiving parameter of your services must be an Array. i mean the "fileName" is the parameter in web services so, it must be an Array type.

VB

$.ajax({
                        type:"POST",
                        url:"http://localhost/TestAndroidWcfService/Service1.svc/UplodImageAndroid",
                        ProcessData:false,
                        contentType:"application/json;charset=utf-8",
                        dataType:"json",
                        data: "{'custImg':'+searchRequest +'}",
                        success:function(data){
			alert("Success:"+ data);
			},
			error:function(xhr,status,error){
			alert("Error"+error);
			}
                    });

Please note Im not sure but, the data parameter name "custImg" and Webservice receiving parameter name "custImg" must be same.

Following steps I followed to pass JSON object to WCF service:
1) format of JSON object as WCF data contract
2) pass the jsonText to wcf service

HTML

var jsonText = JSON.stringify({"fileName": fileName,"ImageBytes":strings});
      
      
      $.ajax({
          type:"POST",          
     url:"http://localhost/TestWcfService/Service1.svc/UplodFile",
          data:jsonText,
          contentType:"application/json;charset=utf-8",
          dataType:"json",
          success:function(data){
          alert("success"+data);
          //alert("Success:"+ data );
          },
          error:function(error){
          alert("Error:"+ error.message );
          }
         });
