Raw bytes as RequestBody not working anymore in v107

[inimirpaz]

Hi everyone,

I used to send a POST API request with raw binary data as follows:

byte[] binaryStream

RestRequest request = new("api/apicall", Method.POST);
request.AddParameter("file", binaryStream, ParameterType.RequestBody);
IRestResponse response = await client.ExecuteAsync(request);

Since I updated and migrated to v107 (107.3.0) this stopped to work. The server receives the ".ToString()" of the bytes array:

--467e3b83-a3ad-4571-8af1-e505c56e0037
Content-Type: text/plain; charset=utf-8
Content-Disposition: form-data; name=file

System.Byte[]
--467e3b83-a3ad-4571-8af1-e505c56e0037--

Please read the docs and use AddFile.

Sorry to bother but using AddFile does not solve the issue for me. On the server side the POST API is processed and the file is extracted from a HttpListenerRequest.InputStream. With RestSharp < v107 the request.AddParameter("file", binaryStream, ParameterType.RequestBody); worked as expected from the server side which received the raw binary data only.

Using AddFile in v107 adds to the raw binary data also the HTTP "boundary" preamble and footer:

--5e04074f-915d-40ab-af14-019fd6116499 Content-Type: audio/wave Content-Disposition: form-data; name="name"; filename="filename"
[RAW BINARY DATA] <--- The server is supposed to receive only this (at least, this is how it worked with < v107)
--5e04074f-915d-40ab-af14-019fd6116499--

Ok, then you can use AddBody with the byte array. It won't work with a stream though.

Hi, thanks for your promptly reply!
I just tried with request.AddBody(byteArray); (byteArray is obviously a byte[]) but on the receiving end all I get is a 13 byte text file with the .ToString() of such array:

System.Byte[]

Edit: Now I am trying to encode the byte array beforehand...

I need to check, it should use the bytes array.

Ok, I will fix the issue later, but the following code should work:

request.AddParameter(new BodyParameter("", byteArray, contentType, DataFormat.Binary));

Thanks! It did the job.
