Getting `Status Code:400 Bad Request` When calling Microsoft Azure Emotion API with data of type `Content-Type:application/octet-stream`

Question

I\'m trying to send data to Microsoft Cognitive Services\' Emotion API, in the form of Content-Type: application/octet-stream.

I\'m getting the Base64 strin

Answer 1

I was doing a very silly thing here. The API Documentation of the Emotion API here says that it needs data as binary image data.

But I was still giving it as JSON. I simply changed the implementation of getUserEmotion method. Instead of

return this.http.post(this.apiUrl, { "data": this.makeBlob(userImageBlob) }, { headers: headers });

I used this

return this.http.post(this.apiUrl, this.makeBlob(userImageBlob), { headers: headers });

Hope this helps someone who's facing the same issue!
