I want to upload a playlist image from my iOS application to the Spotify Web API.
I followed the instructions on the docs page: I requested the ugc-image-upload
, playlist-modify-public
and playlist-modify-private
scopes, added the content type header and made a jpeg Base64 String. But I keep getting back a 405 Method Not Allowed
error. I am able to create a image with the same URL and Authorization Token on android. I already tried to add the android generated Base64 String to my swift request, but this did not work either.
This is a swift code sample generated by Postman where I tried to debug this request. The Base64 String is a 100x100 orange jpeg image which was generated in my android app and worked there. The decoding process does work on this site and the result is the expected image: https://www.base64decode.org In Postman I cannot get this to work, too.
let headers = [
"Authorization": "Bearer […]",
"Content-Type": "image/jpeg",
"Cache-Control": "no-cache"
]
let postData = NSData(data: "/9j/4AAQSkZJRgABAQAAAQABAAD/2wBDAAEBAQEBAQEBAQEBAQEBAQEBAQEBAQEBAQEBAQEBAQEBAQEBAQEBAQEBAQEBAQEBAQEBAQEBAQEBAQEBAQEBAQH/2wBDAQEBAQEBAQEBAQEBAQEBAQEBAQEBAQEBAQEBAQEBAQEBAQEBAQEBAQEBAQEBAQEBAQEBAQEBAQEBAQEBAQEBAQH/wAARCABkAGQDASIAAhEBAxEB/8QAFQABAQAAAAAAAAAAAAAAAAAAAAj/xAAUEAEAAAAAAAAAAAAAAAAAAAAA/8QAFgEBAQEAAAAAAAAAAAAAAAAAAAkK/8QAFBEBAAAAAAAAAAAAAAAAAAAAAP/aAAwDAQACEQMRAD8AvABJ9oAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAf/9k=".data(using: String.Encoding.utf8)!)
let request = NSMutableURLRequest(url: NSURL(string: "https://api.spotify.com/v1/users/[…]/playlists/[…]/images")! as URL, cachePolicy: .useProtocolCachePolicy, timeoutInterval: 10.0)
request.httpMethod = "POST"
request.allHTTPHeaderFields = headers
request.httpBody = postData as Data
let session = URLSession.shared
let dataTask = session.dataTask(with: request as URLRequest, completionHandler: { (data, response, error) -> Void in
if (error != nil) {
print(error)
} else {
let httpResponse = response as? HTTPURLResponse
print(httpResponse)
}
})
dataTask.resume()
And here is the httpResponse
:
Optional(<NSHTTPURLResponse: 0x282fdf300> { URL: https://api.spotify.com/v1/users/[…]/playlists/[…]/images } { Status Code: 405, Headers {
"Access-Control-Allow-Origin" = (
"*"
);
"Cache-Control" = (
"private, max-age=0"
);
"Content-Length" = (
0
);
Date = (
"Fri, 20 Jul 2018 14:12:01 GMT"
);
Via = (
"1.1 google"
);
"access-control-allow-credentials" = (
true
);
"access-control-allow-headers" = (
"Accept, Authorization, Origin, Content-Type, Retry-After"
);
"access-control-allow-methods" = (
"GET, POST, OPTIONS, PUT, DELETE, PATCH"
);
"access-control-max-age" = (
604800
);
allow = (
"GET, HEAD, OPTIONS, PUT"
);
"alt-svc" = (
clear
);
} })
Since the Base64 String, Authorization Token and URL are the same I assume there is something wrong with my request body or header fields.
Thanks in advance!
