curl request in ruby RestClient - ruby-on-rails

Question

The fastbill API states in its docu to make this curl request in order to receive information:
curl -v -X POST \
–u {E-Mail-Adresse}:{API-Key} \
-H 'Content-Type: application/xml' \
-d '{xml body}' \
https://my.fastbill.com/api/1.0/api.php
Using RestClientI tried to translate this into a ruby like request:
How I read this:
- make a post request to https://my.fastbill.com/api/1.0/api.php using basic authentification and stating the content type in the header, correct?
Now this would be a resource based request in RestClient like this:
First I authenticate:
resource = RestClient::Resource.new( 'https://my.fastbill.com/api/1.0/api.php', 'my#email.de', 'API-KEY-XXXXX' )
which works and authorises me.
then putting my request in:
xml = '<?xml version="1.0" encoding="utf-8"?><FBAPI><SERVICE>customer.get</SERVICE><FILTER/></FBAPI>'
resource.post xml, content_type: 'application/xml'
It always returns 400 and I don't know what else to do here.
Also how would json work here?
resource.post param1: 'value', content_type: 'json'
would be obvious.

Answer 1

You can utilize the Restclient::Request.execute. 400 errors typically indicate that the request was not understood by the recipeint. This could be caused by the headers or malformed data. You may need to add the accept header. Try the example below
require 'rest_client'
RestClient::Request.execute(
method: :post,
user: 'api_user#example.com',
password: 'pass123',
url: "https://example/users.json",
headers: {content_type: :json, accept: :json},
payload: { 'user' => { 'name' => 'John Doe', 'email' => 'john.doe#example.com'} }.to_json,
)

$url="https://my.fastbill.com/api/1.0/api.php";
$curl = curl_init();
curl_setopt($curl,CURLOPT_URL, $url);
curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1);
$result = curl_exec($curl);
curl_close($curl);
print_r(json_decode($result));
