BadRequest when PUT JSON data on Firebase REST API

Question

I have this code that I am using to PUT my JSON string on Firebase database:

RestRequest request = new RestRequest("MemberAndChannels/{userId}/{channelId}.json", Method.POST);

request.RequestFormat = DataFormat.Json;
request.AddParameter("auth", accessKey);
request.AddUrlSegment("userId", user.UUID);
request.AddUrlSegment("channelId", channel.UUID);
request.AddHeader("Content-Type", "application/json; charset=utf-8");

request.AddJsonBody(channelJson);

IRestResponse response = client.Execute(request);

if (response.StatusCode == HttpStatusCode.OK)
{

} 
else {

}

But I am getting following error (StatusCode: BadRequest):

"{\n  \"error\" : \"Invalid data; couldn't parse JSON object, array, or value.\"\n}\n"

I've tried PUTing same data using curl and it worked. Can't figure out where I am doing wrong.

Answer 1

The object is being serialized twice (double serialized).

Pass the channel object as it is to AddJsonBody and the request will serialize it to JSON before sending body

request.AddJsonBody(channel);

assuming here channel is an object of a Class

Answer 2

I have modified the code with slight changes. Please try with this

RestRequest request = new RestRequest("MemberAndChannels/{userId}/{channelId}.json", Method.POST);
request.AddParameter("auth", accessKey); // or request.AddHeader("auth", accessKey);
request.AddUrlSegment("userId", user.UUID);
request.AddUrlSegment("channelId", channel.UUID);

request.AddHeader("Content-Type", "application/json");
request.AddHeader("Accept", "application/json");
request.AddParameter("application/json", channelJson, ParameterType.RequestBody);

IRestResponse response = client.Execute(request);

if (response.StatusCode == HttpStatusCode.OK)
{

} 
else {

}

Answer 3

I had the same problem.

I soved it changing this code:

request.AddParameter("auth", accessKey);

by

request.AddQueryParameter("auth", accessKey);

I hope help you.
