Re: [jxm28] How to access an API with Perl?

Hi
Another way is below. This is where I too need help as we need to use restful web services with bearer token. The first set of code is my attempt to replicate c# code (which works) using perl. What am I doing incorrectly? I have not copied the entire c# program but just the key part I am trying to replicate. The perl program is not sending the data correctly so the response I get back is 'error' => 'unsupported_grant_type. I am guessing I have not put the text 'application/x-www-form-urlencoded' or '/token' in the right places in my attempts.
non-coder so limited understanding of c# or perl.
Perl Code Attempt 1
-----------
use JSON;
use MIME::Base64;
use REST::Client;
use Data::Dumper;
my $username = 'someusername';
my $password = 'somepassword';
my $headers = {Accept => 'application/x-www-form-urlencoded', grant_type => "password", username => $username, password => $password};
my $client = REST::Client->new();
$client->setHost('https://api.service.com');
$client->GET(
'/token',
$headers
);
my $response = from_json($client->responseContent());
print Dumper($response);
Perl Code Attempt 2
use JSON;
use MIME::Base64;
use REST::Client;
use Data::Dumper;
my $username = 'someusername';
my $password = 'somepassword';
my $headers = {grant_type => 'password', username => $username, password => $password};
my $client = REST::Client->new();
$client->setHost('https://api.service.com');
$client->addHeader('Content-Type', 'application/x-www-form-urlencoded' );
$client->POST ('/token','',$headers);
my $response = from_json($client->responseContent());
print Dumper($response);
c# Equivalent Code - This Works
--------------------------------------
public async Task<TokenResponse> Login()
{
using (var client = new HttpClient())
{
client.BaseAddress = this.baseUri;
client.DefaultRequestHeaders.Accept.Clear();
client.DefaultRequestHeaders.Accept.Add(
new MediaTypeWithQualityHeaderValue("application/x-www-form-urlencoded"));
var content =
new FormUrlEncodedContent(
new[]
{
new KeyValuePair<string, string>("grant_type", "password"),
new KeyValuePair<string, string>("username", this.username),
new KeyValuePair<string, string>("password", this.password)
});
var response = await client.PostAsync("/token", content);
if (response.StatusCode != HttpStatusCode.OK)
{
return this.userObject;
}
var responseContent = await response.Content.ReadAsStringAsync();
this.userObject = new JavaScriptSerializer().Deserialize<TokenResponse>(responseContent);
return this.userObject;
}
}
