Hi I'm trying to trigger a POST call to the following API. and here's code
var client = new HttpClient();
client.DefaultRequestHeaders.Accept.Clear();
client.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/octet-stream"));
client.DefaultRequestHeaders.Add("Ocp-Apim-Subscription-Key", key);
var queryString = HttpUtility.ParseQueryString(string.Empty);
queryString["returnFaceId"] = "true";
queryString["returnFaceLandmarks"] = "false";
queryString["returnFaceAttributes"] = "age,gender";
var filebytes = File.ReadAllBytes(@"C:\Users\user1\Desktop\IMG.jpg");
var uri = "https://southeastasia.api.cognitive.microsoft.com/face/v1.0/detect?" + queryString;
HttpResponseMessage response;
using (var content = new ByteArrayContent(filebytes))
{
response = client.PostAsync(uri, content).Result;
var result = response.Content.ReadAsStringAsync().Result;
}
I get the following error in result
:
{"error":{"code":"BadArgument","message":"JSON parsing error."}}
This code works fine if I use application/json
, and pass a http link.
As the example code given by Microsoft, can you try to set ContentType
like the sample :
using (var content = new ByteArrayContent(byteData))
{
content.Headers.ContentType = new MediaTypeHeaderValue("< your content type, i.e. application/json >");
response = await client.PostAsync(uri, content);
}
Try to set request content type as "application/octet-stream".
