Member 12976241 7-Apr-17 8:45am

[System.Web.Services.WebMethod(EnableSession = true)]
[ScriptMethod(UseHttpGet=false)]
[WebInvoke(ResponseFormat=WebMessageFormat.Json, RequestFormat = WebMessageFormat.Json, BodyStyle=WebMessageBodyStyle.Bare, Method="POST")]
public void booking_sync()
{
var req = new StreamReader(HttpContext.Current.Request.InputStream);
req.BaseStream.Seek(0, SeekOrigin.Begin);
dynamic body = req.ReadToEnd();

//The Below Code was used when i change the request format
var token = JToken.Parse(body);
var data = token.Value<jarray>("JsonData");
}

Solution 1

Your data is not in a correct format, it must be enclosed in curly braces { and }. See JSON Introduction[^].

hi Mr.Richard, Thanks for your reply.I want to receive the Json Array. This is the correct format for Json Array.

Richard MacCutchan 7-Apr-17 9:45am

Yes, but it is not the correct format for a JSON string, which must be enclosed in curly braces.

Member 12976241 7-Apr-17 9:48am

ok, But the third party given the request in this type only.

Richard MacCutchan 7-Apr-17 9:57am

Then you need to tell them that the data is incorrect.

Solution 2

try

string json  = "[{ \"name\" : \"AAAA\", \"address\" : \"Chennai\"},{\"name\": \"BBBB\", \"address\":\"Trichy\"}]";
           json = "JsonData:{" +  json + "}";

Thanks for your Solution. When I assign the values manually inside the coding, it is working. But When i receive the value from outside, it is not working.

Karthik_Mahalingam 12-Apr-17 7:16am

what do you mean by " But When i receive the value from outside, "

Member 12976241 12-Apr-17 8:05am

Outside means, When the third Party calling this function, at the time they will send some post request. this request contains json array in the body content.

The Request format is
https://gracebeta.com/PMSDEV/TripIBAPI/InstantBooking.asmx/booking_sync -d '[{"reservation_id":"123","partner_hotel_code":"221"}]' -H "Content-Type:application/json"

Karthik_Mahalingam 12-Apr-17 8:16am

so how will you extract the json

Member 12976241 12-Apr-17 8:34am

By using this url, i am unable to get the json array.

Karthik_Mahalingam 12-Apr-17 8:42am

just do a check, if the json is in expected format then parse it directly else append the string as mentioned in the solution.

Member 12976241 12-Apr-17 8:50am

Ok Mr.Karthick. i'll Check it.

Karthik_Mahalingam 12-Apr-17 9:12am
