I'm trying to use apache http components to interface with the Spotify api. The request I'm trying to send is detailed here under #1. When I send this request from bash using curl
curl -H "Authorization: Basic SOMETOKEN" -d grant_type=client_credentials https://accounts.spotify.com/api/token
I get back a token like the website describes
However the following java code, which as far as I can tell executes the same request, gives back a 400 error
Code
String encoded = "SOMETOKEN";
CloseableHttpResponse response = null;
try {
CloseableHttpClient client = HttpClients.createDefault();
URI auth = new URIBuilder()
.setScheme("https")
.setHost("accounts.spotify.com")
.setPath("/api/token")
.setParameter("grant_type", "client_credentials")
.build();
HttpPost post = new HttpPost(auth);
Header header = new BasicHeader("Authorization", "Basic " + encoded);
post.setHeader(header);
try {
response = client.execute(post);
response.getEntity().writeTo(System.out);
}
finally {
response.close();
}
} catch (Exception e) {
e.printStackTrace();
}
Error
{"error":"server_error","error_description":"Unexpected status: 400"}
The URI that the code prints is looks like this
https://accounts.spotify.com/api/token?grant_type=client_credentials
And the header looks like this
Authorization: Basic SOMETOKEN
Am I not constructing the request correctly? Or am I missing something else?
